2. personal safety
ate standards agency. Unapproved
safety equipment may not provide
adequate protection. Eye protection
must be ANSI-approved and breath-
ing protection must be NIOSH-ap-
proved for the specific hazards in the
work area.
a.stay alert, watch what you are do-
ing and use common sense when
operating a power tool. do not use
a power tool while you are tired
or under the influence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
3. power tool use and care
a.do not force the power tool. use
the correct power tool for your ap-
plication. The correct power tool will
do the job better and safer at the rate
for which it was designed.
b.use personal protective equip-
ment. always wear eye protection.
Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or
hearing protection used for appropri-
ate conditions will reduce personal
injuries.
b.do not use the power tool if the
switch does not turn it on and off.
Any power tool that cannot be con-
trolled with the switch is dangerous
and must be repaired.
c.prevent unintentional starting.
ensure the switch is in the off-
position before connecting battery
pack, picking up or carrying the
tool. Carrying power tools with your
finger on the switch or energizing
power tools that have the switch on
invites accidents.
c.disconnect the battery pack from
the power tool before making any
adjustments, changing accesso-
ries, or storing power tools. Such
preventive safety measures reduce
the risk of starting the power tool ac-
cidentally.
d.do not overreach. Keep proper
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
d.store idle power tools out of the
reach of children and do not allow
persons unfamiliar with the power
tool or these instructions to oper-
ate the power tool. Power tools are
dangerous in the hands of untrained
users.
e.dress properly. do not wear loose
clothing or jewelry. Keep your
hair, clothing and gloves away
from moving parts. Loose clothes,
jewelry or long hair can be caught in
moving parts.
e.maintain power tools. check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. if dam-
aged, have the power tool repaired
before use. Many accidents are
caused by poorly maintained power
tools.
f. if devices are provided for the con-
nection of dust extraction and col-
lection facilities, ensure these are
connected and properly used. Use
of these devices can reduce dust-
related hazards.
g.only use safety equipment that
has been approved by an appropri-

f. use the power tool and tool bits
in accordance with these instruc-
tions, taking into account the
working conditions and the work
to be performed. Use of the power
tool for operations different from
those intended could result in a haz-
ardous situation.
tool performance is decreasing.
When tool performance begins to
diminish, stop the tool, recharge the
Battery Pack, and use the fresh Bat-
tery Pack for optimal performance.
5. service
a.Have your power tool serviced by
a qualified repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.
4. Battery tool use and care
a.recharge only with the charger
specified by the manufacturer. A
charger that is suitable for one type of
battery pack may create a risk of fire
when used with another battery pack.
drill safety Warnings
1. Hold power tools by insulated grip-
ping surfaces when performing an
operation where the cutting tool
may contact hidden wiring or its
own cord. Contact with a ″live″ wire
will make exposed metal parts of the
tool ″live″ and shock the operator.
b.Use power tools only with specifi-
cally designated battery packs.
Use of any other battery packs may
create a risk of injury and fire.
c.When battery pack is not in use,
keep it away from other metal ob-
jects, like paper clips, coins, keys,
nails, screws or other small metal
objects, that can make a connec-
tion from one terminal to another.
Shorting the battery terminals togeth-
er may cause burns or a fire.
2. Maintain labels and nameplates on
the tool. These carry important safety
information. If unreadable or miss-
ing, contact Harbor Freight Tools for a
replacement.
d.under abusive conditions, liquid
may be ejected from the battery;
avoid contact. if contact acciden-
tally occurs, flush with water. If
liquid contacts eyes, additionally
seek medical help. Liquid ejected
from the battery may cause irritation
or burns.
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.
e.always switch to a fresh Battery
pack when tool performance be-
gins to diminish. Severe heat is de-
structive to a Battery Pack. The more
heat generated, the faster the Battery
Pack loses power. A Battery Pack
that gets too hot can be permanently
damaged. Never over-discharge a
Battery Pack by using the tool while
6. Do not leave the tool unattended
when it is plugged into an electrical
outlet. Turn off the tool, and unplug it
from its electrical outlet before leav-
ing.

10. Some dust created by power sand-
ing, sawing, grinding, drilling, and
other construction activities, contains
chemicals known [to the State of Cali-
fornia] to cause cancer, birth defects
or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints
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.
• Crystalline silica from bricks and ce-
ment or other masonry products
• Arsenic and chromium from chemi-
cally treated lumber
Do not place the charger on a flam-
mable surface. Do not obstruct any
vents on the charger. especially
avoid placing the charger on car-
pets 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. Fre-
quently monitor the charger and
battery during use.
Your risk from these exposures var-
ies, depending on how often you do
this type of work. To reduce your
exposure to these chemicals: work in
a well ventilated area, and work with
approved safety equipment, such as
those dust masks that are specially
designed to filter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
11. WARNING: Handling the cord on
this product will expose you to lead,
a chemical known to the State of
California to cause cancer, and birth
defects or other reproductive harm.

instructions.
1. Anyone using vibrating tools regu-
larly 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, ner-
vous 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 pos-
sible.
2. Do not smoke during use. Nico-
tine 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 between dif-
ferent processes.
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.
