–
Threaded mounting of accessories must
match the grinder spindle thread. For ac
cessories mounted by flanges, the arbour
hole of the accessory must fit the locating
diameter 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.
–
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 power tool or accessory is drop
ped, inspect for damage or install an un
damaged 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 mi
nute. Damaged accessories will normally
break apart during this test time.
–
Wear personal protective equipment. De
pending on application, use face shield,
safety goggles or safety glasses. As ap
propriate, wear dust mask, hearing pro
tectors, gloves and workshop apron capa
ble of stopping small abrasive or work
piece fragments. The eye protection must
be capable of stopping flying debris gener
ated by various operations . The dust mask
or respirator must be capable of filtrating
particles generated by your operation. Pro
longed exposure to high intensity noise may
cause hearing loss.
–
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.
–
Hold the power tool by insulated gripping
surfaces only, when performing an opera
tion where the cutting accessory may con
tact hidden wiring. Cutting accessory con
tacting a "live" wire may make exposed
metal parts of the power tool "live" and
could give the operator an electric shock.
–
Never lay the power tool down until the
accessory has come to a complete stop.
The spinning accessory may grab the sur
face and pull the power tool out of your
control.
–
Do not run the power tool while carrying it
at your side. Accidental contact with the
spinning accessory could snag your cloth
ing, pulling the accessory into your body.
–
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 haz
ards.
–
Do not operate the power tool near flam
mable materials. Sparks could ignite these
materials.
–
Do not use accessories that require liquid
coolants. Using water or other liquid cool
ants may result in electrocution or shock.
Further safety instructions for all operations
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 cau
ses 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, de
pending 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 incor
rect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
–
Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxili
ary handle, if provided, for maximum con
trol over kickback or torque reaction dur
ing start-up. The operator can control tor
que reactions or kickback forces, if proper
precautions are taken.
–
Never place your hand near the rotating
accessory. Accessory may kickback over
your hand.
–
Do not position your body in the area
where power tool will move if kickback oc
curs. Kickback will propel the tool in direc
tion opposite to the wheel’s movement at
the point of snagging.
