Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to reduce the
risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
2. Do not operate battery charger in explosive atmospheres, such as in the presence of flammable
liquids or dust. Batteries and battery chargers may create sparks which may ignite the dust or fumes.
Caution must be exercised when charging, hydrogen, an explosive gas, is released when charging
lead-acid batteries. Always allow proper ventilation to the charger and battery and keep the hood open
during use.
3. Keep bystanders, children, and visitors away while operating a battery charger. Distractions can
cause you to lose control. Protect others in the work area from debris such as corrosion materials and
sparks. Provide barriers or shields as needed.
4. Grounded battery chargers must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or modify the
plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in
doubt whether the outlet is properly grounded. If the battery charger should electrically malfunction
or break down, grounding provides a low resistance path to carry electricity away from the user.
5. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators.
There is an increased risk of electric shock if your body is grounded.
6. Do not expose battery charger to rain or wet conditions. Water entering a battery charger will
increase the risk of electric shock.
7. Do not abuse the Battery Cables. Never use the Battery Cables to carry the tool. Keep the Bat-
tery Cables away from heat, oil, sharp edges, or moving parts. Replace damaged Battery Cables
immediately. Damaged Battery Cables increase the risk of electric shock.

Personal Safety
8. Stay alert. Watch what you are doing, and use common sense when operating a battery charger.
Do not use a battery charger while tired or under the influence of drugs, alcohol, or medication.
A moment of inattention while operating a battery charger may result in serious personal injury.
9. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving
parts.
10. Do not overreach. Keep proper footing and balance at all times during installation. Proper foot-
ing and balance enables better control in unexpected situations.
11. Use safety equipment. Always wear eye protection. Always wear ANSI approved splash resistant
safety eye goggles and heavy work gloves when working on or around lead-acid batteries. Wear long
sleeve shirt, long pants and work shoes. Using personal safety devices reduce the risk for injury.
12. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure.
Battery Charger Use and Care
13. Use bolts and included clamps to secure and support the battery charger to a stable platform.
This battery charger is designed to be installed on the compartment wall, battery holder or other structure near the vehicle battery.
14. Do not force the battery charger. Use the correct battery charger for your application. The cor-
rect battery charger will do the job better and safer at the rate for which it is designed.
15. Do not use the battery charger if the automatic control does not turn it on or off. If you observe the
LED lights not reacting roughly as expected according to the chart on page 8, disconnect and remove
the Battery Charger from the vehicle.
16. Disconnect the Power Cord Plug (not included) from the power source and from the charger
before making any adjustments, changing accessories, storing the battery charger, or driving
the vehicle. Such preventive safety measures reduce the risk of accidents.
17. Keep battery charger maintained and clean. Properly maintained battery chargers are less likely
to fail and are easier to control. Do not use a damaged battery charger. Tag damaged battery chargers
“Do not use” until repaired.
18. Check for misalignment or binding of support brackets, breakage of parts, and any other condi-
tion that may affect the battery charger operation. If damaged, have the battery charger serviced
before using. Many accidents are caused by poorly maintained battery chargers.
19. Use only accessories that are recommended by the manufacturer for your model. Accessories
that may be suitable for one tool may become hazardous when used on another tool.
Specific Safety Rules
1. Maintain labels and nameplates on the Battery Charger. These carry important information. If unreadable
or missing, contact Harbor Freight Tools for a replacement.
2. Avoid contact with Battery Acid. If splashed, unplug Onboard Battery Charger and immediately wash
affected area with clean water away from the battery and charger. Continue washing area until medical
help arrives.
3. Turn vehicle ignition off before making cable connections. Vehicle’s engine must be cooled down before
making cable connections.
