7. 
Do not use a damaged accessory. Before each 
use inspect the accessory such as abrasive 
wheels 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.
 Cutting accessory contacting a 
"live" wire may make exposed metal parts of the 
power tool "live" and shock the operator. 
11.  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. 
12.  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.   
13.  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. 
14.  Do not operate the power tool near flammable 
materials. Sparks could ignite these materials. 
15.  Do not use accessories that require liquid 
coolants. Using water or other liquid coolants may 
result in electrocution or shock. 
16.  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. 
a) 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. 
b)  Never place your hand near the rotating 
accessory.
 Accessory may kickback over your 
hand. 
c) Do not position your body in the area where 
power tool will move if kickback occurs.
 
Kickback will propel the tool in direction opposite to 
the wheel’s movement at the point of snagging. 
d)  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. 
e)  Do not attach a saw chain woodcarving 
blade or toothed saw blade.
 Such blades create 
frequent kickback and loss of control 
17.  Safety Warnings Specific for Grinding: 
a) Use only wheel types that are recommended 
for your power tool.
 Wheels for which the power 
tool was not designed cannot be adequately 
guarded and are unsafe. 
b) 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. 
c)  Do not use worn down wheels from larger 
power tools.
 Wheel intended for larger power tool 
is not suitable for the higher speed of a smaller tool 
and may burst.
