h ) Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the tool
in unexpected situations.
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 ALL OPERATIONS
Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive, Cutting-Off Operations
a ) This power tool is intended to function as a grinder,
sander, wire brush, 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 ) 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.
c ) 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 break
and fly apart.
d ) 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.
e ) Threaded mounting of accessories must match the
grinder spindle thread. For accessories mounted by
flanges, the arbor 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.
f ) 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 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.
g ) 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.
h ) 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.
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.
j ) 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.
k ) 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.
l ) 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.
m ) 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.
n ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
o ) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may result in
electrocution or shock.
p ) Do not use Type 11 (flaring cup) wheels on this tool.
Using inappropriate accessories can result in injury.
q ) Always use side handle. Tighten the handle securely.
The side handle should always be used to maintain control of
the tool at all times.
r ) When starting the tool with a new or replacement
wheel, or a new or replacement wire brush installed,
hold the tool in a well protected area and let it run for
one minute. If the wheel has an undetected crack or
flaw, it should burst in less than one minute. If the wire
brush has loose wires, they will be detected. Never start
the tool with a person in line with the wheel. This includes
the operator.
s ) Use of accessories not specified in this manual is
not recommended and may be hazardous. Use of power
boosters that would cause the tool to be driven at speeds
greater than its rated speed constitutes misuse.
t ) Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding the
work by hand or against your body leaves it unstable and may
lead to loss of control.
u ) Avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the wheel
for cracks or flaws.
v ) Always handle and store wheels in a careful manner.
w ) Do not operate this tool for long periods of time.
Vibration caused by the operating action of this tool
may cause permanent injury to fingers, hands, and
arms. Use gloves to provide extra cushion, take frequent rest
periods, and limit daily time of use.
x ) Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught in
moving parts.
