9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or  
across running machines.  
10. Maintain tools with care. Keep tools clean for better and safer performance.  
Inspect tool cords periodically, and if damaged, have them repaired by an authorized  
technician. The handles must be kept clean, dry, and free from oil and grease at all  
times.  
11. Disconnect power. Unplug Charger Engine Starter when not in use.  
12. Avoid unintentional starting. Be sure the switch is in the Off position when not in  
use and before plugging in.  
13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool  
when you are tired.  
14. Check for damaged parts. Before using any tool, any part that appears damaged  
should be carefully checked to determine that it will operate properly and perform its  
intended function. Check for alignment and binding of moving parts; any broken parts  
or mounting fixtures; and any other condition that may affect proper operation. Any  
part that is damaged should be properly repaired or replaced by a qualified technician.  
Do not use the tool if any switch does not turn On and Off properly.  
15. Guard against electric shock. Prevent body contact with grounded surfaces such as  
pipes, radiators, ranges, and refrigerator enclosures.  
16. Replacement parts and accessories. No replacement parts available.  
17. Do not operate tool if under the influence of alcohol or drugs. Read warning  
labels on prescriptions to determine if your judgment or reflexes are impaired while  
taking drugs. If there is any doubt, do not operate the tool.  
18. Use proper size and type extension cord. If an extension cord is required, it must be  
of the proper size and type to supply the correct current to the tool without heating up.  
Otherwise, the extension cord could melt and catch fire, or cause electrical damage  
to the tool. This tool requires use of an extension cord of 0 to 15 amps capability (up  
to 25 feet), with wire size rated at 16 AWG. Longer extension cords require larger size  
wire. If you are using the tool outdoors, use an extension cord rated for outdoor use  
(signified by “WA” on the jacket).  
19. Maintenance. For your safety, maintenance should be performed regularly by a  
qualified technician.  
Note:Performance of this tool (if powered by line voltage) may vary depending on varia-  
tions in local line voltage. Extension cord usage may also affect tool performance.  
Warning:The warnings, cautions, and instructions discussed in this instruction manual  
cannot cover all possible conditions and situations that may occur. It must be under-  
stood by the operator that common sense and caution are factors which cannot be built  
into this product, but must be supplied by the operator.

Additional Battery Charger Safety Warnings:  
1. Only use this Charger Engine Starter with lead acid, rechargeable type batteries. Remove  
battery caps to check liquid level inside battery. If liquid is not present or if liquid appears to  
be frozen, do not attempt to charge battery.  
2. Do not use this Charger Engine Starter as a low voltage system power supply except in  
automotive applications.  
3. Do not try to start the automobile engine when the battery is still charging. It may damage  
the unit.  
4. Do not use this Charger Engine Starter to charge household dry cell batteries. Dry cell bat-  
teries may explode causing personal injury and property damage.  
5. Always charge lead acid batteries in well ventilated areas as explosive gases may be pro-  
duced during charging.  
6. Place the Charger Engine Starter as far away as possible from the battery you are  
charging.  
7. Never attempt to charge a battery with frozen fluid.  
8. Be careful not to drip any fluids in or around the Charger Engine Starter. Damage to the  
Charger Engine Starter can occur.  
9. Never touch the Charger Engine Starter cable clamps together when the charger is plugged  
in; touching the cables together will cause sparking and possible personal injury and/or  
property damage.  
10. Do not touch your eyes after working with a lead acid battery. Wash your hands  
thoroughly with soap and water.  
11. If battery fluids contact your skin, face, or eyes, immediately flush with plenty of fresh  
water, and then contact a doctor.  
12. Never smoke around a charging battery.  
13. Make all cable clamp connections before plugging in the Charger Engine Starter.  
14. Remove all metal objects (including tools, personal objects such as a watch or jewelry)  
from around the battery being charged.  
15. Don’t use the Charger Engine Starter in damp or wet locations.  
How Batteries Charge.  
A charger doesn’t force current into a battery, but makes a limited amount available, and the  
battery draws what it needs, up to or slightly greater than the output amp rating of the char-  
ger.  
The closer the battery is to zero charge, the more current is drawn. Beginning with a dead  
battery, the charger’s ammeter registers toward the high amp end, and falls toward zero as  
charging progresses. Remember, the ammeter registers the amount of current being drawn  
from the battery, not the delivery capability of the charger.  
After the charger reaches 100% charge, it continues to draw on low level, converting it into  
heat inside the battery. If left connected, after a full charge, the battery acid will eventually boil,  
overcharging and damaging the battery.  
Warning!! This Charger Engine Starter doesn’t have an automatic cut off. It is equipped with  
a 2-1/2 hour timer. Always check the battery and the time manually. Don’t depend solely on  
the timer. Leaving the Charger Engine Starter unattended can result in property damage and/

Operation  
1. Place the Charger Engine Starter at least five feet from the battery to be charged.  
2. If the battery is to be charged in a vehicle, make sure the ignition is off and the key is  
removed. Then, connect the positive (red with + sign) cable clamp to the positive (P or  
+) terminal of the battery.  
3. Connect the negative (Black with the - sign) to an unpainted solid metal portion of the  
vehicle.  
4. Set the Charger Engine Starter Switch to the proper setting for the type of battery being  
charged. Refer to Table 1 on Page 6.  
5. With the battery clamps in place, and the Rotary Switch correctly set, plug the 3-prong  
line cord into a grounded electrical outlet or extension cord.  
6. The Charger Engine Starter is now supplying charging current to the battery. View the  
Ammeter to see the amount of charging current. (The Ammeter displays the amount of  
the “current draw” of the battery. As it charges, it draws less current.The Ammeter moves  
toward zero as the battery charges.)

Ammeter  
Timer: The main function of the timer is to prevent over charging while allowing a battery time  
to obtain a satisfactory charge. To properly set the timer, you must know the size of the battery  
in ampere hours or reserve capacity in minutes, and the state of charge. Often the state of  
charge is not known, which is one reason why the timer is limited to 3 hours. With the aid of  
a battery load tester (not included) the state of the charge can be obtained in a few seconds.  
For example, the average size automotive battery at a 50% state of charge will

Operation (continued)  
require 1 to 1-1/2 hours of charging at the 40 amp rate to reach the full charge state. For the  
same battery with its timer set to maximum, 3 hours overcharging will occur.Slight overcharging  
will not likely harm a battery that was otherwise in good condition. When the state of charge  
is unknown, start out with a timer setting of one hour or less.  
Hold: This position defeats the timer function, allowing for continuous operation. Use it when  
you want to charge more than 3 hours. This is normally used when the 2 amp charge rate  
is selected. Be sure to monitor the charging and stop the charge when the battery is fully  
charged.  
Rotary Switch: Use the rotary switch to select the charge rate or engine start setting your  
require. Read the switch dial for the appropriate setting.  
Ammeter: The ammeter indicates the amount of current measured in amperes that’s drawn  
from the battery. For example, in the 40 amp charge rate a typical discharged battery will ini-  
tially draw approximately 40 amps. As the battery continues to charge, current will taper to 15  
to 20 amps at full charge. When cranking an engine, the starter motor draws upward to 200  
amps. The meter needle will be at the extreme right side. The 2 amp charge rate may indicate  
some activity on the meter. The meter doesn’t have the resolution to display this low rate.  
Engine Start  
1. Set the charge rate and timer to the off positions.  
2. With the Charger unplugged from the AC outlet, connect the Charger to the battery.  
3. Plug the Charger AC power cord into the AC outlet, then move OFF to HOLD position.  
4. Set the charge rate to the engine start position that matches the vehicle battery, and then  
crank the engine. Follow the duty cycle printed on the front panel of your charger for  
proper ON/OFF times. During extremely cold weather, or when the battery is severely  
exhausted, charge the battery for about five minutes before attempting to crank the en-  
gine.  
5. If the engine fails to start, charge the battery for five more minutes before cranking the  
engine.  
6. After the engine starts, move the charge rate switch to OFF and unplug the AC power  
cord from the outlet before disconnecting the DC cable clamps.
