c) 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.
d) The rated speed of the accessory must be at least equal to the maximum speed marked on the
power tool. Accessories runningfaster than their ratedspeed can break and fly apart.
e) The outside diameter and the thickness of your accessory must be within the capacity rating of
your power tool. Incorrectlysized accessoriescannot be adequatelyguarded or controlled.
f) Threaded mounting of accessories must match the GRINDER spindle thread. For accessories
mounted byFLANGES, thearbour hole of the accessorymust fit the locatingdiameter of the FLANGE.
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.
g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels
for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked
wires. If a 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 normallybreak apart during this test time.
h) Wear personal protective equ
i
pment. 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
filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing
loss.
i) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear
personal protectiveequipment.Fragments of workpiece or of a broken accessory may fly away and cause
injury beyond immediate area of operation.
j) Hold the power tool by insulated gripp
i
ng 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 give the operator an electric shock.
k) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning accessory.
I) 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.
m)Do not runthe power tool while carrying it at your side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into your body.
n) 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.
o) Do not operate the power tool near flammable materials. Sparks could ignite these materials.
p) Do not use accessories that require liqu
i
d coolants. Usingwater or otherliquid coolants may result in
electrocution or shock.
3.2 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 wheelsmayalso 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 auxiliaryhandle, if provided, for maximum control o
v
er kickback or torque reaction
during start-up. The operatorcan control torque reactionsor kickback forces, if properprecautions are taken.
b) Never place your hand near the rotating accessory. Accessory may kickback over your hand.
