SAFETY OPERATION MAINTENANCESETUP
Cut-Off Machine Safety Warnings
1. The guard provided with the tool must be
securely attached to the power tool and
positioned for maximum safety, so the least
amount of wheel is exposed towards the
operator. Position yourself and bystanders
away from the plane of the rotating wheel.
The guard helps to protect operator from broken
wheel fragments and accidental contact with wheel.
2. Use only bonded reinforced or diamond
cut-off wheels for your power tool. Just
because an accessory can be attached to your
power tool, it does not assure safe operation.
3. The rated speed of the accessory must be at
least equal to the maximum speed marked
on the power tool. Accessories running faster
than their rated speed can break and fly apart.
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
5. Always use undamaged wheel flanges that
are of correct diameter for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
6. Do not use worn down reinforced wheels
from larger power tools. Wheels intended
for a larger power tool are not suitable for the
higher speed of a smaller tool and may burst.
7. 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 guarded or controlled.
8. The arbour size of wheels and flanges
must properly fit the spindle of the power
tool. Wheels and flanges with arbour holes
that do not match the mounting hardware of
the power tool will run out of balance, vibrate
excessively and may cause loss of control.
9. Do not use damaged wheels. Before each
use, inspect the wheels for chips and
cracks. If power tool or wheel is dropped,
inspect for damage or install an undamaged
wheel. After inspecting and installing the
wheel, position yourself and bystanders
away from the plane of the rotating wheel
and run the power tool at maximum no load
speed for one minute. Damaged wheels will
normally break apart during this test time.
10. Wear personal protective equipment. Depending
on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and shop
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.
11. 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 wheel may fly away and
cause injury beyond immediate area of operation.
12. Hold the power tool by insulated gripping
surfaces only, when performing an
operation where the cutting accessory may
contact hidden wiring. Cutting accessory
contacting a “live” wire may make exposed
metal parts of the power tool “live” and could
give the operator an electric shock.
13. Never lay the power tool down until the
accessory has come to a complete stop.
The spinning wheel may grab the surface
and pull the power tool out of your control.
14. 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.
15. 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.
16. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
17. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
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.
3. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.

SAFETYOPERATIONMAINTENANCE SETUP
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush
or any other 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 abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel 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 wheel’s
movement at the point of pinching. Abrasive wheels
may also break under these conditions.
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. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.
2. Never place your hand near the
rotating accessory. Accessory
may kickback over your hand.
3. Do not position your body in line with
the rotating wheel. Kickback will propel
the tool in direction opposite to the wheel’s
movement at the point of snagging.
4. 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.
5. Do not attach a saw chain, woodcarving
blade, segmented diamond wheel with
a peripheral gap greater than 10mm or
toothed saw blade. Such blades create
frequent kickback and loss of control.
6. Do not “jam” the wheel or apply excessive
pressure. Do not attempt to make an
excessive depth of cut. Overstressing the
wheel increases the loading and susceptibility
to twisting or binding of the wheel in the cut and
the possibility of kickback or wheel breakage.
7. When wheel is binding or when interrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the wheel from the cut while
the wheel is in motion otherwise kickback
may occur. Investigate and take corrective
action to eliminate the cause of wheel binding.
8. Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel
may bind, walk up or kickback if the power
tool is restarted in the workpiece.
9. Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
10. Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.

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
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.
6. 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.
7. Do not use a battery pack or power tool that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
8. Do not expose a battery pack or power tool to
fire or excessive temperature. Exposure to fire
or temperature above 140°F may cause explosion.
9. Follow all charging instructions and do
not charge the battery pack or power tool
outside of the temperature range specified
in the instructions. Charging improperly or at
temperatures outside of the specified range may
damage the battery and increase the risk of fire.

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.
