e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool's
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in
accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
5) SERVICE
a) 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.
SAFETY INSTRUCTIONS FOR ANGLE GRINDERS
1) SAFETY INSTRUCTIONS FOR ALL OPERATIONS
a) This power tool is intended to function as a grinder
or cut-off tool. Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious injury.
b) This power tool is not recommended for sanding,
wire brushing or polishing. Operations for which the
power tool was not designed may create a hazard and
cause personal injury.
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 running faster than their rated speed
can fly apart.
e) 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.
f) Threaded mounting of accessories must match the
grinder spindle thread. For accessories 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.
g) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, backing pads for cracks, tear or
excess wear, wire brushes for loose or cracked
wires. If the 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.
h) 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.
i) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of the
workpiece or of a broken accessory may fly away and
cause injury beyond the immediate area of operation.
j) Hold power tool by insulated gripping surfaces only,
when performing an operation where the cutting
accessory may contact hidden wiring or its own
cord. A cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live" and
could 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.
l) 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 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.
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 liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
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 the 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.
