forces applied to these wheels may cause 
them to shatter.
e) 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.
f)  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.
g) 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.
h) 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.
i)  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.
j)  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.
k) 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.
I)  Hold the 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.
m) Position the cord clear of the spinning 
accessory. lf you lose control, the cord 
may be cut or snagged and your hand or 
arm may be pulled into the spinning wheel.
n) 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.
o) 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.
p) 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.
q) Do not operate the power tool near 
flammable materials. Sparks could ignite 
these materials.
r)  Do not use accessories that require 
liquid coolants. Using water or other 
liquid coolants may result in electrocution 
or shock.
