Contact with a ″live″ wire will make exposed metal
parts of the tool ″live″ and shock the operator.
2. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
3. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
4. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.
5. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.
6. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
7. 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.
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.
8. This product is not a toy.
Keep it out of reach of children.
9. 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.
10. WARNING: The cord of this product contains
lead and/or di (2-ethylhexyl) phthalate
(DEHP), chemicals known to the State
of California to cause cancer, and birth
defects or other reproductive harm. Wash
hands after handling. (California Health
& Safety Code § 25249.5, et seq.)
11. 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.
This tool vibrates during use.
Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for
an extended period should first be examined
by a doctor and then have regular medical
check-ups to ensure medical problems are not
being caused or worsened from use. Pregnant
women or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or
Raynaud’s Disease should not use this tool.
If you feel any symptoms related to vibration (such
as tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.

3. Charge Battery Pack only according
to its Charger’s instructions.
4. Inspect Battery Pack before every use;
do not use or charge if damaged.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
E&$*- Extension cords must not be used with this item’s Charger.
