IMPORTANT SAFETY INFORMATION

GENERAL POWER TOOL SAFETY WARNINGS

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 term ″power tool″ in the warnings refers to your
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, 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. Do not overreach. Keep proper footing and
balance at all times. This enables better control

of the power tool in unexpected situations.

5. 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.

6. 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.

7. 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.

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 battery pack 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. 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.

Battery Tool Use and Care

1. 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.

Page 2 For technical questions, please call 1-888-866-5797. Item 58846

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

battery packs may create a risk of injury and fire.

3. 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

terminals together may cause burns or a fire.

4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the

battery may cause irritation or burns.

Service

1. 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.

2. Never service damaged BATTERY packs. Service

of BATTERY packs should only be performed by
the manufacturer or authorized service providers.

Safety Warnings Common

For Grinding Operations:

1. This power tool is intended to function
as a grinder. 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.

2. Operations such as sanding, wire brushing,
polishing or cutting-off are not recommended
to be performed with this power tool. Operations

for which the power tool was not designed may
create a hazard and cause personal injury.

3. Do not use accessories which are not
specifically designed and recommended
by the tool manufacturer. Just because

the accessory can be attached to your power
tool, it does not assure safe operation.

4. The RATED SPEED of the accessories must be at
least equal to the operating speed setting marked
on the power tool. Accessories running faster

than their RATED SPEED can break and fly apart.

5. The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized

accessories cannot be adequately controlled.

6. The arbour size of accessories must properly
fit the spindle or collet of the power tool.

Accessories that do not match the mounting

hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.

7. Do not use a damaged accessory. Before
each use inspect the accessory for chips and
cracks. If power tool or accessory is dropped,
inspect for damage or install an undamaged
accessory. After inspecting and installing an
accessory, position yourself and bystanders
away from the plane of the rotating accessory
and run the power tool at maximum no-load
speed for one minute. Damaged accessories

will normally break apart during this test time.

8. Wear personal protective equipment. Depending
on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and workshop
apron capable of stopping small abrasive or
workpiece fragments. The eye protection must

be capable of stopping flying debris generated by
various operations. The dust mask or respirator
must be capable of filtrating particles generated
by your operation. Prolonged exposure to high

intensity noise may cause hearing loss.

9. Keep bystanders a safe distance away
from work area. Anyone entering the
work area must wear personal protective
equipment. Fragments of workpiece or of

a broken accessory may fly away and cause

injury beyond immediate area of operation.

10. Hold power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting

accessory contacting a “live” wire may make

exposed metal parts of the power tool “live” and
could give the operator an electric shock.

11. Always hold the tool firmly in your hand(s) during
the start-up. The reaction torque of the motor, as it

accelerates to full speed, can cause the tool to twist.

12. Use clamps to support workpiece whenever
practical. Never hold a small workpiece in
one hand and the tool in the other hand while
in use. Clamping a small workpiece allows you

to use your hand(s) to control the tool. Round
material such as dowel rods, pipes or tubing

have a tendency to roll while being cut, and may

cause the bit to bind or jump toward you.

13. Never lay the power tool down until the
accessory has come to a complete stop.

The spinning accessory may grab the surface
and pull the power tool out of your control.

14. After changing the bits or making any
adjustments, make sure the collet nut, chuck
or any other adjustment devices are securely
tightened. Loose adjustment devices can

unexpectedly shift, causing loss of control, loose
rotating components will be violently thrown.

15. Do not run the power tool while carrying
it at your side. Accidental contact with the

spinning accessory could snag your clothing,
pulling the accessory into your body.

Page 3For technical questions, please call 1-888-866-5797.Item 58846

16. Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside

the housing and excessive accumulation of
powdered metal may cause electrical hazards.

17. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.

18. Do not use accessories that require liquid
coolants. Using water or other liquid coolants

may result in electrocution or shock.

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

20. Avoid unintentional starting. Prepare to
begin work before turning on the tool.

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

22. Use clamps (not included) or other practical
ways to secure and support the workpiece to
a stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control and personal injury.

23. 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.

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

25. 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:

• Avoid operating alone.

• Do not use with power switch locked on.

• Properly maintain and inspect
to avoid electrical shock.

26. 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.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or
snagged rotating accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the
accessory’s rotation at the point of the binding.

For example, if an accessory is snagged or pinched
by the workpiece, the edge of the accessory that is
entering into the pinch point can dig into the surface
of the material causing the wheel to climb out or
kick out. The wheel may either jump toward or away
from the operator, depending on direction of the
accessory’s movement at the point of pinching.

Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.

1. Maintain a firm grip on the power tool and

position your body and arm to allow you
to resist kickback forces. The operator

can control torque reactions or kickback

forces, if proper precautions are taken.

2. Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing

have a tendency to snag the rotating accessory
and cause loss of control or kickback.

3. Do not attach a toothed saw blade. Such blades
create frequent kickback and loss of control.

4. When using rotary files, always have the work
securely clamped. These accessories will grab

if they become slightly canted in the groove, and
can kickback. When a rotary file grabs, it may jump
from the groove and you could lose control of the
tool. Feeding the tool in the wrong direction causes
the cutting edge of the bit to climb out of the work
and pull the tool in the direction of this feed.

Safety Warnings Specific

For Grinding:

1. For threaded abrasive cones and plugs
use only undamaged wheel mandrels with
an unrelieved shoulder flange that are of
correct size and length. Proper mandrels

will reduce the possibility of breakage.

2. Do not position your hand in line with and behind
the rotating accessory. When the accessory, at

the point of operation, is moving away from your
hand, the possible kickback may propel the spinning
accessory and the power tool directly at you.

Lithium Battery Safety Warnings

LITHIUM BATTERIES STORE A
LARGE AMOUNT OF ENERGY AND
WILL VENT FIRE OR EXPLODE IF
MISTREATED:

1. Keep Battery Pack dry.

2. DO NOT DO ANY OF THE FOLLOWING
TO THE BATTERY PACK:

• Open,

• Drop,

• Short-circuit,

• Puncture,

• Incinerate, or

• Expose to temperatures greater than 140° F.

3. Charge Battery Pack only according to instructions.

4. Inspect Battery Pack before every use;
do not use or charge if damaged.

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 medical or
physical 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 between different 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.
