IMPORTANT SAFETY INFORMATION

GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.

Failure to follow all instructions listed below may result
in electric shock, fire and/or serious injury.

Save all warnings and instructions
for future reference.

The term ″power tool″ in the warnings refers
to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.

Work Area Safety

1. Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools

create sparks which may ignite the dust or fumes.

3. Keep children and bystanders
away while operating a power tool.

Distractions can cause you to lose control.

Electrical Safety

Do not expose power tools to rain or wet
conditions. Water entering a power tool

will increase the risk of electric shock.

Personal Safety

1. Stay alert, watch what you are doing 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.

2. Use personal protective equipment. Always wear
eye protection. Protective equipment such

as dust mask, non-skid safety shoes, hard hat,

or hearing protection used for appropriate
conditions will reduce personal injuries.

3. Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to
power source and/or 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.

4. Remove any adjusting key or wrench before
turning the power tool on. A wrench or

a key left attached to a rotating part of the
power tool may result in personal injury.

5. Do not overreach. Keep proper footing and
balance at all times. This enables better control

of the power tool in unexpected situations.

6. 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.

7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

8. Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action

can cause severe injury within a fraction of a second.

9. Only use safety equipment that has been approved
by an appropriate standards agency. Unapproved
safety equipment may not provide adequate
protection. Eye protection must be ANSI-approved
and breathing protection must be NIOSH-approved
for the specific hazards in the work area.

10. 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.

11. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.

12. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.

Keep it out of reach of children.

14. 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.

15. 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.

Power Tool Use and Care

1. Do not force the power tool. Use the
correct power tool for your application.

The correct power tool will do the job better and
safer at the rate for which it was designed.

2. Do not use the power tool if the switch
does not turn it on and off. Any power tool

that cannot be controlled with the switch

is dangerous and must be repaired.

3. Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
from the power tool before making any
adjustments, changing accessories, or storing
power tools. Such preventive safety measures

reduce the risk of starting the power tool accidentally.

4. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions
to operate the power tool. Power tools are

dangerous in the hands of untrained users.

5. Maintain power tools and accessories.
Check for misalignment or binding of moving
parts, breakage of parts and any other
condition that may affect the power tool’s
operation. If damaged, have the power tool
repaired before use. Many accidents are

caused by poorly maintained power tools.

6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
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 hazardous situation.

8. Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles

and grasping surfaces do not allow for safe handling
and control of the tool in unexpected situations.

Battery Tool Use and Care

1. Prevent unintentional starting. Ensure the

switch is in the off-position before connecting
to battery pack, picking up or carrying the
power tool. Carrying the power tool with your
finger on the switch or energizing power tool

that have the switch on invites accidents.

2. Disconnect the battery pack from the
power tool before making any adjustments,
changing accessories, or storing power tool.

Such preventive safety measures reduce the

3. 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.

4. Use power tools only with specifically
designated battery packs. Use of any other

battery packs may create a risk of injury and fire.

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

Vibration Safety

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.

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.
