when the manual was prepared. However,  
owing to Grizzly’s policy of continuous  
improvement, changes may be made at  
any time with no obligation on the part of  
Grizzly.  
Read the manual before assembly  
and operation. Become familiar with  
this machine, its safety instructions,  
and its operation before beginning  
any work. Serious personal injury  
may result if safety or operational  
information is not understood or fol-  
lowed.

Unpacking  
Site Placement  
When determining where to set up the air  
compressor in the shop or when taking the  
air compressor to a job site, the most  
important consideration is access to an  
adequate and properly fused power sup-  
ply. Refer to Circuit Requirements for the  
needs of your particular compressor.  
This air compressor is shipped from the  
manufacturer in a carefully packed carton.  
If you discover the machine is damaged  
after you have signed for delivery, and the  
truck and driver are gone, you will need to  
file a freight claim with the carrier. Save the  
containers and all packing materials for  
possible inspection by the carrier or its  
agent. Without the packing materials, filing  
a freight claim can be difficult. If you need  
assistance determining whether you need  
to file a freight claim, or with the procedure  
to file one, please contact our Customer  
Service at (570) 546-9663.  
Also, make sure the compressor is not  
operating in an environment where there  
are explosives, flammable or caustic  
fumes or gases. A clear and well ventilated  
area is best for safe operation.  
Place the compressor on a solid and level  
surface. Make sure that the hoses you  
attach to your pneumatic device will be  
unrestricted in movement and not subject  
to being run over by vehicles or punctured  
by any sharp objects in the area.  
Since air compressors are often used for a  
sustained period of time, sometimes in  
restricted areas, it is also best to wear ear  
protection to avoid long term exposure to  
the sound of the electric motor and piston.  
The Model H4517/H4518 represents  
a heavy load at 60 pounds. Seek  
assistance before moving.  
Do not place the compressor next to  
any flammable liquids or gas! The  
compressor cylinder head and feed  
pipe can reach high temperatures and  
could cause the flammable gas to  
ignite. Keep work area clear from  
flammable gas when using the com-  
pressor.  
Long term exposure to this machine  
may cause hearing loss. Wear  
approved hearing protection while  
operating this machine to minimize  
this risk!

CIRCUIT REQUIREMENTS  
110V Operation  
Grounding  
In the event of an electrical short, ground-  
ing reduces the risk of electric shock by  
providing a path of least resistance to dis-  
perse electric current. These machines are  
equipped with power cords having an  
equipment-grounding conductor. See  
Figure 1. The outlet must be properly  
installed and grounded in accordance with  
all local codes and ordinances.  
The Model H4517/H4518 Air Compressor  
is wired for 110V, single-phase operation  
only. The maximum amperage draw for the  
machine is 17 amps, with a fusing level rat-  
ing of 20 amps.  
It is best to operate a compressor on a  
dedicated circuit, i.e. a circuit where there  
are no other electrical appliances plugged  
in. The fuse requirements above assume  
the use of a circuit breaker or a slow-blow  
fuse. If an unusual load does not exist and  
the compressor still breaks the circuit, con-  
tact a qualified electrician or our service  
department at (570) 546-9663.  
Extension Cords  
If you find it necessary to use an extension  
cord with your compressor, make sure the  
cord is rated Standard Service (grade S) or  
better. Refer to the chart in the standard  
safety instructions to determine the mini-  
mum gauge for the extension cord. The  
extension cord must also contain a ground  
wire and plug pin. Always repair or replace  
extension cords when they become worn  
or damaged.  
Figure 1. Ground plug configuration.  
Overheating, short circuit, and fire  
damage may result from inadequate  
wiring. Follow the guidelines in this  
section.  
Potential for electrical shock hazard,  
this equipment must be grounded.  
Verify that any existing electrical  
outlet and circuit you use is actually  
grounded.

PREPARING FOR USE  
Before using your Grizzly Air  
Compressor, follow these steps:  
NOTICE  
1. Remove all packing materials and any  
protective plastic bags, zip tie labels  
or tags from the compressor.  
The machine should never be run  
without a full oil reservoir. The oil  
provides lubrication to the cylinder  
rings which deliver the compressed  
air. Severe damage to the internal  
moving parts can occur if there is  
not adequate oil flow. Check the oil  
level frequently, and change the oil  
every 3 months.  
2. Be sure the air filter is attached to the  
cylinder head as shown in Figure 2.  
5. Know and understand the duty cycle  
of the compressor before operating.  
Duty Cycle  
The Model H4517/H4518 Air Compressor  
should NOT be operated on more than a  
50% duty cycle. (This means an air com-  
pressor that pumps air for over 30 minutes  
in one hour is considered misuse. Also,  
this could mean that the air compressor is  
undersized for the required air demand.)  
Note—The maximum compressor pump  
time per hour is 30 minutes.  
Figure 2. Air filter attached to  
cylinder hear.  
3. ADD OIL TO THE CRANKCASE. Oil  
has been supplied with your air com-  
pressor. Remove the oil breather on  
top of the crankcase and add oil into  
the hole. The oil level should be in the  
center of the sight gauge shown in  
Figure 3.  
Overheating, short circuit and fire  
damage will result from operating  
beyond the recommended duty  
cycle. Severe injury and property  
damage could occur.  
Figure 3. Proper oil level.  
4. Make sure the drain valve on the air  
tank is closed.

STARTING  
To start the air compressor:  
Check the pressure gauge to see that the  
tank pressure climbs to approximately 100-  
115 PSI or around 8 BAR, then automati-  
cally turns off.  
1. Make sure the compressor switch is in  
the OFF position (lever with red cap  
above pressure gauges shown in  
Figure 4) before connecting to the  
power supply.  
Note—If the compressor does not auto-  
matically kick off, flip the ON/OFF switch to  
OFF before the pressure gets too high.  
See the Pressure Regulator section.  
Operating this equipment has the  
potential for flying debris to cause  
eye injury. Always wear safety glass-  
es or goggles when operating equip-  
ment. Everyday glasses or reading  
glasses only have impact resistant  
lenses, they are not safety glasses.  
Be certain the safety glasses you  
wear meet the appropriate standards  
of the American National Standards  
Institute (ANSI).  
Figure 4. ON/OFF lever.  
2. Close the drain valve, shown in  
Figure 5, so the tank can build up  
pressure.  
Figure 5. Drain valve location.  
3. Double check the oil level to make  
sure it is at the proper height.  
4. Connect the compressor to the power  
supply.  
5. Flip the switch to the ON position  
(where it reads AUTO).

AIR CONTROL  
Air Release  
Delivered Pressure  
The tank pressure is displayed on the left  
pressure gauge, and the air to be delivered  
to the tool is displayed on the right pres-  
sure gauge, shown in Figure 6.  
There are two ways to release air from the  
compressor tank other than through your  
regulator and the use of air tools:  
—The drain valve  
—The safety drain valve  
To release air by using the drain valve, you  
simply turn the release nut to allow air to  
flow out of the tank. The drain valve is  
shown in Figure 5. The drain valve is also  
used to drain condensation that builds up  
in the tank.  
The safety valve automatically releases  
pressure if the tank reaches 130 PSI.  
Figure 6. Pressure gauges.  
To manually release the air in the tank  
by using the safety drain valve:  
To control the air delivery to your tool:  
1. Locate the safety drain valve on the  
tank. The drain valve is shown below  
in Figure 8.  
1. Adjust the air control knob, shown in  
Figure 7, to set the PSI that will be  
delivered to your tool. Turn the knob  
clockwise to increase the pressure  
and counter-clockwise to decrease  
the pressure.  
Figure 8. Safety drain valve.  
2. Pull the metal ring on top of the safe-  
ty valve to bleed pressure from the  
tank. Note—The ring is preset to  
release air if the tank exceeds its  
maximum pressure. DO NOT try to  
adjust the safety valve pressure set-  
ting!  
Figure 7. Air control knob.  
Note—The air tool that you attach to the air  
compressor should have a preferred PSI  
operating level. Set the pressure to be  
delivered to the tool according to the  
required level of the tool. Understand the  
duty cycle of the air compressor.

Tank Pressure  
Regulator  
To adjust the pressure regulator:  
1. Unplug the air compressor from  
the power supply.  
The pressure regulator has been factory  
set for the highest quality operating perfor-  
mance.  
2. Make sure the compressor switch is in  
the OFF position.  
3. Drain the pressure from the tank.  
The pressure regulator ensures the pump  
will shut off when the correct PSI is  
reached for the air compressor tank.  
4. Remove the black ON/OFF switch  
cover by removing the screw which is  
in the recess on the top of the cover.  
Pull the black cover up and set it  
aside.  
NOTICE  
The Model H4517/H4518 Air  
Compressors have been factory set  
to kick off at the proper PSI range.  
Only attempt to adjust the pressure  
regulator if your air compressor  
does not reach or pressurizes  
beyond the proper PSI level.  
5. Turn the pressure adjustment screw  
(Figure 9) a half turn clockwise to  
increase the tank pressure and a half  
turn counter-clockwise to decrease  
the pressure.  
6. Connect the compressor to the power  
supply and start compressor.  
7. If the PSI level still needs adjustment,  
repeat steps 1 through 6.  
8. Replace the cover when the proper  
adjustments have been made.

CONNECTING TOOLS  
To connect air tools to your air com-  
pressor:  
Consideration should also be given to the  
type of usage. A nailer or staple gun uses  
air in short bursts and it is easier for the  
compressor to maintain pressure. A paint  
sprayer or grinder tends to use a more  
continuous stream of air as these tools are  
run for longer time periods. It is always  
better to oversize a compressor to allow  
for variation in the type of usage and the  
number of tools to be powered. Air tools  
being operated with insufficient air volume  
will not perform their function satisfactorily.  
1. Make sure the compressor model you  
use has a sufficient cubic feet per  
minute (CFM) output for the air tool  
you plan to connect. (Most air tools  
will have an air requirement stated in  
terms of a specific CFM at a specific  
pressure.)  
2. The compressor should put out a  
higher CFM than the tool requires.  
If you are connecting multiple tools  
that will be used simultaneously, then  
the CFM for each tool should be  
added together and compared to the  
compressor output value.  
3. Connect the tool, using a good quality  
air line with an adequate length to  
reach from the compressor to the  
point of use.  
NoteQuick-connect couplers, shown in  
Figure 10, are a good option for a fast and  
sure connection of tools and air hoses.  
Always disconnect air hose from  
tools whenever not in use or while  
servicing! During maintenance, a  
tool connected to air may operate  
accidentally, causing serious per-  
sonal injury!  
The  
Model  
H4517/H4518  
Air  
Compressors  
are specifically  
designed for air tool operation. DO  
NOT MODIFY OR USE THIS  
MACHINE FOR ANY OTHER PUR-  
POSE. Modifications or improper  
use of this tool will void the warran-  
ty. If you are confused about any  
aspect of this machine, DO NOT use  
it until you have answered all your  
questions. Serious personal injury  
may occur.  
Figure 10. Quick connect couplers  
These couplers are included with the air  
compressor. Make certain the air hose will  
not be placed in a position where it can  
become constricted or cut by a sharp  
object. Note—Running over a hose with  
heavy vehicles may not cause an immedi-  
ate leak, but it will shorten the life of the  
hose.

MAINTENANCE  
Each Use  
Regular periodic maintenance on your  
air compressor will ensure its optimum  
performance. Make a habit of inspect-  
ing your compressor each time you use  
it. Check the following items:  
The air compressor will cycle auto-  
matically when it is on. When per-  
forming any type of maintenance  
always make sure the AUTO/OFF  
lever is in the OFF position the unit  
is unplugged and bleed out all tank  
pressure.  
1. Check Oil Level! Use the sight gauge  
on the bottom of the crankcase to  
make sure the oil level is at the prop-  
er height.  
2. Drain tanks daily of any condensation  
by opening the drain valve on the bot-  
tom of the tank and leave open until  
the next time it is used.  
3. Clean off the cylinder head cooling  
fins. Dirt interferes with heat transfer.  
4. Check for worn or damaged cords  
and plugs.  
Depending upon the amount of use and  
the surrounding humidity, a certain amount  
of condensed water may accumulate in the  
tanks. For longevity of the compressor  
seals and the air tools you connect, it is  
best to drain water from the tanks. The  
tanks are best drained if the drain valve is  
open when the system is pressurized.  
5. Check for any other condition that  
could hamper the safe operation of  
this machine.  
6. Check the safety drain valve to make  
sure it is working properly.  
Always wear safety glasses and use  
extreme caution when working  
around compressed air. The force of  
the air stream can cause small bits  
of debris to become airborne and  
cause potential injury to the eyes or  
other parts of the body. Never let the  
full force of the air stream come in  
direct contact with the skin as it can  
cause abrasions or bruising, pene-  
tration of skin and could even lead  
to death!  
Always drain the air from the tank  
before performing any maintenance  
or transporting your air compressor.  
Damage to the air compressor while  
under pressure could cause burst-  
ing or explosion and injury or prop-  
erty damage could occur.
