to be performed with this power
tool. Operations for which the
power tool was not designed may
create a hazard and cause personal
injury.
2.
Only persons well acquainted with
these rules of safe operation should
be allowed to use the tool.
Safety glasses and ear
protection must be worn
during operation.
3.
Do not wear loose fitting clothing,
scarves, or neck ties in work area.
Loose clothing may become caught
in moving parts and result in serious
personal injury.
4.
Do not wear jewelry when operating
any tool. Jewelry may become
caught in moving parts and result in
serious personal injury.
5.
Always use attachments designed for
use with this tool. Do not use
damaged or worn attachments.
6.
Never trigger the tool when not
applied to a work object.
Attachments must be securely
attached. Loose attachments can
cause serious injury.
7.
Never point a tool at oneself or any
other person. Serious injury could
occur.
8.
Use steady, even pressure when
using tool. Do not force. Too much
pressure can cause grinding wheel to
break or overheat.
9.
Keep all nuts, bolts and screws tight
and ensure equipment is in safe
working condition.
10.
Do not put hands near or under
moving parts.
11.
Always use proper guard with
grinding wheel. The guard protects
operator from broken wheel
fragements.
12.
Accessories must be rated for at least
11,000 RPM. Wheels and other
accessories running over rated speed
can fly apart and cause injury.
13.
Grinding wheel and guard must be
securely attached as described in this
operating manual before connecting
the grinder to a power source.
14.
Grinding wheels must be stored in a
dry place.
15.
Before attaching the grinding wheel,
inspect it for visible defects. If
cracked, chipped, or warped, do not
install it.
16.
Do not overtighten the clamp nut on
the grinding wheel. Excessive
tightening can cause the wheel to
crack during operation.
17.
Make sure that the guard is in good
condition and securely installed
before operating grinder.
18.
Do not clamp the grinder in a vise or
use as a fixed grinder.
19.
Never turn on the grinder with the
grinding wheel or any rotating parts
touching the workpiece.
20.

a
rnings
Read all
safety
warnings and all instructions. Failure
to follow the warnings and instruc-
tions may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for
future reference.
The term "power tool" in the warnings
refers to your mains-operated (corded)
power tool or battery-operated (cord-
less) power tool.
WORK AREA SAFETY
Keep
work
area clean and well lit. Cluttered or
dark areas invite accidents.
Do not operate power tools
in explosive atmospheres,
such as in the presence of flammable
liquids, gases or dust. Power tools cre-
ate sparks which may ignite the dust or
fumes.
Keep
children
and bystanders away while operating a
power tool. Distractions can cause you
to lose control.
Do not
operate
the power tool near flammable
materials. Sparks could ignite these
materials.
ELECTRICAL SAFETY
Power tool plugs must match
the outlet. Never modify the
plug in any way. Do not use
any adapter plugs with earthed
(grounded) power tools. Unmodified
plugs and matching outlets will reduce
risk of electric shock.
Avoid
body
contact with earthed or grounded sur-
faces, such as pipes, radiators, ranges
and refrigerators. There is an increased
risk of electric shock if your body is
earthed or grounded.
Do not
expose
power tools to rain or wet conditions.
Water entering a power tool will
increase the risk of electric shock.
Do not
abuse
the cord. Never use the cord for carry-
ing, pulling or unplugging the power
tool. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged
or entangled cords increase the risk of
electric shock.
When
operat-
ing a power tool outdoors, use an
extension cord suitable for outdoor
use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
If operat-
ing a
power tool in a damp location is
unavoidable, use a residual current
device (GFCI) protected supply. Use of a
GFCI reduces the risk of electric shock.
1.
Do not use accessories that require
liquid coolants. Using water or
other liquid coolants may result in
electrocution or shock.
2.
Do not operate tool with damaged
cord or plug.
•
Have a damaged or worn power
cord and/or strain relief replaced
immediately.
•
Do not attempt to repair power
cord.
3.
Make sure cord is located so that it
will not be stepped on, tripped
over, or otherwise subjected to
damage or stress.
4.
Do not use an extension cord unless
absolutely necessary. Use of
improper extension cord could
result in a risk of fire and electric
shock. If an extension cord must be
used, make sure:
