IMPORTANT SAFETY INFORMATION

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury. Save

all warnings and instructions for future reference.

The warnings, precautions, and instructions discussed
in this instruction manual cannot cover all possible
conditions and situations that may occur.
It must be understood by the operator that common
sense and caution are factors which cannot be built into
this product, but must be supplied by the operator.

1. The battery Charger gets hot during use.
The Charger’s heat can build up to unsafe
levels and create a fire hazard if it does
not receive adequate ventilation, due to

an electrical fault, or if it is used in a hot environment.
Do not place the Charger on a flammable surface.
Do not obstruct any vents on the Charger.

Especially avoid placing the Charger on carpets
and rugs; they are not only flammable, but they
also obstruct vents under the Charger. Place the

Charger on a stable, solid, nonflammable surface
(such as a stable metal workbench or concrete floor)
at least 1 foot away from all flammable objects, such
as drapes or walls. Keep a fire extinguisher and a
smoke detector in the area. Frequently monitor the
Charger and Battery Pack while charging.

2. Charge only designated battery packs;

others may overheat, leak, or burst.

3. Follow charging instructions.

4. Do not insert damaged battery pack.

5. Check frequently while charging.

6. Wear ANSI-approved safety goggles during use.

7. Use chargers only with specifically designated

battery packs. Use of any other battery
packs may create a risk of injury and fire.

8. When battery pack is not in use, keep it away

from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another. Shorting the battery pack

terminals together may cause burns or a fire.

9. Under abusive conditions, liquid may be

ejected from the battery pack; avoid contact.
If contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the

battery pack may cause irritation or burns.

10. Do not expose to rain or wet conditions.
Indoor use only.

11. Inspect before every use; do not use
if parts are loose or damaged.

12. Use as intended only.

13. Unplug after use and before
service, cleaning or storage.

14. Maintain labels and nameplates on
the Charger. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.

15. This product is not a toy.
Keep it out of reach of children.

16. 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.
In addition, people with pacemakers should properly
maintain and inspect to avoid electrical shock.

17. WARNING: The cord of this product contains
lead and/or di (2-ethylhexyl) phthalate (DEHP),
chemicals known to the State of California
