open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
kill.
3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.
Do not touch these “hot” parts with your bare
skin or wet clothing. Wear dry, hole-free
gloves to insulate hands.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:
FUMES AND GASES
can be dangerous.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases.When welding, keep
your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep

• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
fumes and gases away from the breathing zone. When
welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection
should be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical
(earth) ground.
5.b. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors to
form phosgene, a highly toxic gas, and other irritating prod-
ucts.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
5.c. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
3.h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage
between the two can be the total of the open circuit voltage
of both welders.
5.d. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.

SAFETY
WELDING SPARKS can
cause fire or explosion.
CYLINDER may explode
if damaged.
6.a. Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
the welding sparks from starting a fire.
Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.
process used and properly operating
regulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.
7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.
7.c. Cylinders should be located:
•Away from areas where they may be struck or subjected to
physical damage.
6.c. When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.
•A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even though they have
been “cleaned”. For information, purchase “Recommended
Safe Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.
7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a
welding area.
FOR ELECTRICALLY
powered equipment.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate cir-
cuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s
recommendations.
6.h. Also see item 1.c.

ELECTRIC SHOCK can kill.
STORING
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
1. Store the machine in a cool, dry place when it is not
in use. Protect it from dust and dirt. Keep it where
it can’t be accidentally damaged from construction
activities, moving vehicles, and other hazards.
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
2. Drain the engine oil and refill with fresh 10W30 oil.
Run the engine for about five minutes to circulate
oil to all the parts. See the MAINTENANCE section
of this manual for details on changing oil.
• Use in open, well ventilated areas or
vent exhaust outside.
------------------------------------------------------------------------
MOVING PARTS can injure.
3. If you are storing the machine for more than 30
days, drain the coolant from the radiator. Open the
cock at the bottom of the radiator and remove the
pressure cap so that the coolant drains completely.
Attach a note that says “NO WATER” on the radia-
tor.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
See additional warning information at
front of this operator’s manual.
-----------------------------------------------------------
4. Remove the battery, recharge it, and adjust the
electrolyte level. Store the battery in a dry, dark
place.
Only qualified personnel should install,
use, or service this equipment.
5. If the engine is not used for a long period of time,
every two to three months fill the radiator and run
the engine for about five minutes to keep it free
from rust.
LOCATION AND VENTILATION
Whenever you use the RANGER 300, be sure that
clean cooling air can flow through the machine’s
diesel engine and the machine case. Avoid dusty,
dirty areas. Also, keep the machine away from heat
sources. Do not place the engine end of the machine
anywhere near hot engine exhaust from another
machine or closer than two feet from a wall. And of
course, make sure that engine exhaust is ventilated to
an open, outside area.
STACKING
RANGER 300 machines CANNOT be stacked.
TILTING
Place the machine on a secure, level surface whenev-
er you use it or store it. Any surfaces you place it on
other than the ground must be firm, non-skid, and
structurally sound.
The RANGER 300 may be used outdoors. Do not set
the machine in puddles or otherwise submerge it in
water. Such practices pose safety hazards and cause
improper operation and corrosion of parts.
The diesel engine is designed to run in a level position
for best performance. It can operate at an angle, but
this should never be more than 20 degrees in any
direction. If you do operate it at a slight angle, be sure
to check the oil regularly and keep the oil level at the
FULL mark as it would be in its normal level condition.
Also, fuel capacity will be a little less at an angle.
Always operate the RANGER 300 with the case roof
on and all machine components completely assem-
bled. This will protect you from the dangers of moving
parts, hot metal surfaces, and live electrical devices.

WELDING CABLE CONNECTIONS
6. Check and tighten the connections periodically.
CABLE SIZE AND LENGTH
Be sure to use welding cables that are large enough.
The correct size and length becomes especially
important when you are welding at a distance from the
welder.
CAUTION
• Loose connections will cause the output terminals to
overheat. The terminals may eventually melt.
• Do not cross the welding cables at the output termi-
nal connection. Keep the cables isolated and sepa-
rate from one another.
Table A.1 lists recommended cable sizes and lengths
for rated current and duty cycle. Length refers to the
distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.

PREMISES WIRING
The RANGER 300 is suitable for temporary, standby,
or emergency power using the engine manufacturer’s
recommended maintenance schedule. With its three-
wire grounded neutral generator, it can be permanent-
ly installed as a standby power unit for 240 volt, three
wire, single phase 50 ampere service.
The control panel of the RANGER 300 features three
auxiliary power receptacles: See Figure B.1.
• Two 15 amp, 120 volt duplex (double outlet) recepta-
cles.
• One 50 amp 120/240 volt simplex (single outlet)
receptacle.
WARNING
Only a licensed, certified, trained electrician should
install the machine to a premises or residential elec-
trical system. Be certain that:
Through these receptacles the machine can supply up
to 12,000 rated continuous watts of single-phase, 60
Hz AC power.
• The installation complies with the National Electrical
Code and all other applicable electrical codes.
For further protection against electric shock, any elec-
trical equipment connected to the generator recepta-
cles must use a three-blade, grounded type plug or an
Underwriter’s Laboratories (UL) approved double
insulation system with a two-blade plug. Lincoln
offers an accessory plug kit that has the right type of
plugs. See the ACCESSORIES section of this manual
for more information.
• The premises is isolated and no feedbacking into
the utility system can occur. Certain state and local
laws require the premises to be isolated before the
generator is linked to the premises. Check your
state and local requirements.
• A double pole, double throw transfer switch in con-
junction with the properly rated double throw circuit
breaker is connected between the generator power
and the utility meter.
------------------------------------------------------------------------
The following information and the connection diagram,
Figure A.1, can be used as a guide by the electrician
for most applications to premises wiring.
If you need ground fault protection for hand-held
equipment refer to the K896-1 GFCI Receptacle kit in
the ACCESSORIES section of this manual for more
information.
CIRCUIT BREAKERS
1. Install a double pole, double throw switch between
the power company meter and the premises dis-
connect. The switch rating must be the same as or
greater than the premises disconnect and service
overcurrent protection.
The RANGER 300 machines are equipped with 50
amp circuit breakers on the 120/240 V receptacle and
15 amp circuit breakers on the 120 receptacles for
overload protection. Under high heat a breaker may
tend to trip at lower loads than it would normally.
2. Take the necessary steps to assure that the load is
limited to the capacity of the RANGER 300 by
installing a 50 amp 240 volt double pole circuit
breaker. Maximum rated load for the 240 volt auxil-
iary is 50 amperes. Loading above 50 amperes will
reduce output voltage below the allowable -10% of
rated voltage. This may damage appliances or
other motor-driven equipment.
CAUTION
Never bypass the circuit breakers. Without overload
protection, the RANGER 300 D/DLX could overheat
and/or cause damage to the equipment being used.
------------------------------------------------------------------------
3. Install a 50 amp 120/240 volt plug (NEMA type 14-
50) to a double pole circuit breaker using No. 8 or
larger, 4 conductor cable of the desired length.
(The 50 amp 120/240 volt plug is available in the
optional power plug kit.
4. Plug this cable in to the 50 amp 120/240 volt recep-
tacle on the RANGER 300 case front.

3. Attach the work clamp securely to the work you are
welding.
4. Insert the electrode into the electrode holder.
FIGURE B.4
WELDING CIRCUIT CONNECTIONS
5. Set the IDLER CONTROL to AUTO and start the
diesel engine.
AFTER YOU FINISH WELDING:
1. Stop the engine.
6. Set the RANGE switch to a setting equal to or
slightly lower than the welding current recommend-
ed for the electrode being used. For the best weld-
ing performance, always set the RANGE switch to
the lowest CC-blue setting that will give the desired
weld current. This will assure that the OUTPUT
dial is set towards the high end of the dial. If the
OUTPUT dial is set at 10 and the welding current
is to low, move the RANGE switch to the next high-
est setting.
2. Allow the electrode and work to cool completely.
3. Remove the work clamp from the work.
4. Remove any remaining piece of electrode from the
electrode holder.
5. If you are finished using the RANGER 300 for
welding, disconnect the welding cables from the
weld output terminals. Reattach the flange nuts
and leave them on the terminals.
7. Set the POLARITY switch to the desired polarity
(CC-blue setting).
8. Set the OUTPUT control. For stick welding,
always use a setting between 5 and 10 on the dial
(blue range).
9. Strike an arc and begin welding. The OUTPUT
control can be adjusted while welding.
CAUTION
DO NOT change the RANGE switch setting while
welding. This can result in damage to the switch.

OPERATION
operated at 120 V or 9 to 11 Amps when operated at
240 V, it should be connected to the 120/240 dual
voltage receptacle. The full load current of a 1.5 HP
motor is typically 15 to 17 Amps when operated at 120
V or 7.5 to 8.5 Amps when operated at 240 V, it also
should be connected to the 120/240 dual voltage
receptacle. a 1.0 HP that draws less than 15 Amps at
120 V can be plugged into one of the 120 V duplex
receptacles.
AUXILIARY POWER
The Ranger 300 can provide up to 12,000 watts of
120/240 volts AC, Single phase 60 HZ power for con-
tinuous use. The front of the machine includes three
receptacles for connecting AC power Plugs, one 50
amp 120/240 volt NEMA 14-50R receptacle and two
15 amp 120 volt NEMA 5-15R receptacles. Do not
connect any plugs that connect to the power recepta-
cles in parallel.
SIMULTANEOUS WELDING AND POWER
LOADS
Start the engine and set the "IDLER" control switch to
the desired operating mode. Set the "CONTROL" to
10. Voltage is now correct at the receptacles for auxil-
iary power.
Auxiliary power ratings are with no welding load.
Simultaneous welding and power loads are permitted
by the following table. The permissible currents
shown assume that current is being drawn from either
the 120 volt or 240 volt supply (not both at the same
time).
Most single phase motors through 2.0 HP can be
started if there is no load on the motor or other load
connected to the machine. Since the full load current
of a 2.0 HP motor is typically 18 to 20 Amps when

Ambient Temperature
Above 25°C (77°F)
0°C (32°F) to 25°C(77°F)
Below 0°C (32°F)
5. Refill the engine with the proper amount and type
of oil as described in the CHANGING THE OIL
section. Start the engine and check for leaks
around the filter element. Correct any leaks (usu-
ally by retightening the filter, but only enough to
stop leaks) before placing the RANGER 300 back
in service.
SAE 10W-30, SAE10W-40 or SAE30
SAE 10W-30, SAE10W-40 or SAE20
SAE 10W-30, SAE10W-40 or SAE10
4. Reinstall the oil fill cap and the dipstick and start
the engine. Run for several minutes and stop
engine - Wait 5 minutes to allow the oil to come
down to the oil pan and check oil level again.
6. If there are no leaks, stop the engine and recheck
the oil level. If necessary, add oil to bring the level
up to the FULL mark, but do not overfill.

MAINTENANCE
FUEL
AIR CLEANER
At the end of each day’s use, refill the fuel tank
to minimize moisture condensation and dirt contami-
nation in the fuel line. Do not overfill; leave room for
the fuel to expand.
The Kubota diesel engine is equipped with a dry type
air filter. Never apply oil to it. Service the air cleaner
as follows:
Use only fresh, No. 2 grade DIESEL fuel. Do not use
kerosene.
1. Remove the dust cup from the bottom of the air
cleaner housing. Clean out any accumulated dust.
See the Kubota Engine Operator's Manual for instruc-
tions on replacing the fuel filter.
2. If dust is sticking to the element, blow compressed
air through the element from the inside out. Turn
the element as you apply air. Air pressure should
be under 99 psi (68 newton/cm2). Replace the fil-
ter if there is carbon or oil on the element.
BLEEDING THE FUEL SYSTEM
You will need to bleed air from the fuel system any
time the fuel filter or fuel lines have been detached
and refitted; after the fuel tank has been run out of
fuel; or before using the engine after long storage.
Bleed the fuel system as follows:
3. Replace the element at least every 600 hours of
operation and sooner under dusty conditions.
TIGHTENING THE FAN BELT
If the fan belt is loose, the engine can overheat and
the battery lose its charge. Check tightness by press-
ing on the belt midway between the pulleys. It should
deflect bout .25 in. under a load of 20 lbs. (9 Kg) (6
mm).
WARNING
To avoid personal injury, do not bleed a hot engine.
This could cause fuel to spill onto a hot exhaust mani-
fold, creating a danger of fire.
------------------------------------------------------------------------
Refer to Figure D.2
1. Fill the fuel tank, Open the fuel cock.
COOLING SYSTEM
2. Open the air vent plug on the fuel injection pump
two turns using a 10mm wrench.
WARNING
HOT COOLANT can burn skin.
3. Move the fuel feed pump lever by hand until fuel
flows out of the air vent plug.
• Do not remove cap if radiator is
hot.
4. Tighten the air vent plug.
------------------------------------------------------------------------
AIR VENT PLUG
Check the coolant level by observing the level in the
plastic reserve overflow tank. Add 50/50 antifreeze /
water solution if the level is close to or below the
"LOW" mark. do not fill above the "FULL" mark.
Remove radiator cap and add coolant to radiator if
overflow tank is empty.
To drain the coolant, open the petcock at the bottom
or the radiator. Open the radiator cap to allow com-
plete drainage. (Tighten the petcock and refill with a
50/50 antifreeze/water solution.) Use an automotive
grade (low silicate) ethylene glycol antifreeze. The
cooling system capacity is 5.4 quarts (5.1L.). Replace
and tighten the radiator cap.

MAINTENANCE
To prevent ELECTRICAL DAMAGE when:
CAUTION
a) Installing a battery.
b) Using a booster.
Always premix the antifreeze and clean tap water
before adding to the radiator or the overflow tank. It is
very important that a precise 50/50 solution be used
with this engine year round. This gives proper cooling
during hot weather and freezing protection to -34° F (-
37° C).
Use correct polarity - Negative Ground.
To prevent BATTERY DISCHARGE, if you have an
ignition switch, turn it off when engine is not
running.
Cooling solution exceeding 50% ethylene glycol can
result in engine overheating and damage to the
engine. Coolant solution must be premixed before
adding to radiator.
------------------------------------------------------------------------
CLEANING THE BATTERY
Keep the battery clean by wiping it with a damp cloth
when dirty. If the terminals appear corroded, discon-
nect the battery cables and wash the terminals with an
ammonia solution or a solution of 1/4 pound (0.1113
kg) of baking soda and 1 quart (0.946 l) of water. Be
sure the battery vent plugs (if equipped) are tight so
that none of the solution enters the cells.
------------------------------------------------------------------------
Periodically remove the dirt from the radiator fins.
Periodically check the fan belt and radiator hoses.
Replace if signs of deterioration are found.
After cleaning, flush the outside of the battery, the bat-
tery compartment, and surrounding areas with clear
water. Coat the battery terminals lightly with petroleum
jelly or a non-conductive grease to retard corrosion.
Keep the battery clean and dry. Moisture accumula-
tion on the battery can lead to more rapid discharge
and early battery failure.
BATTERY MAINTENANCE
WARNING
GASES FROM BATTERY can explode.
CHECKING ELECTROLYTE LEVEL
● Keep sparks, flame and cigarettes
away from battery.
If battery cells are low, fill them to the neck of the filler
hole with distilled water and recharge. If one cell is
low, check for leaks.
To prevent EXPLOSION when:
● INSTALLING A NEW BATTERY — disconnect
negative cable from old battery first and connect to
new battery last.
The battery is a group 45, with a rating of 495 cold
cranking amps.
● CONNECTING A BATTERY CHARGER —
remove battery from welder by disconnecting nega-
tive cable first, then positive cable and battery
clamp. When reinstalling, connect
negative cable last. Keep well ventilated.
● USING A BOOSTER — connect positive lead to
battery first then connect negative lead to negative
battery lead at engine foot.
BATTERY ACID can burn eyes and
skin.
● Wear gloves and eye protection and
be careful when working near battery.
● Follow instructions printed on battery.

MAINTENANCE
CHARGING THE BATTERY
When you charge, jump, replace, or otherwise con-
nect battery cables to the battery, be sure the polarity
is correct. Improper polarity can damage the charging
circuit. The RANGER 300 positive (+) battery termi-
nal has a red terminal cover.
If you need to charge the battery with an external
charger, disconnect the negative cable first, then the
positive cable before you attach the charger leads.
after the battery is charged, reconnect the positive
battery cable first and the negative cable last. Failure
to do co can result in damage to the internal charger
components.
Follow the instructions of the battery charger manu-
facturer for proper charger settings and charging
time.
