22. 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.

maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing 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.

repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
26. Follow instruction for lubricating and changing
accessories.
27. Keep handles dry, clean and free from oil and
grease.

GRINDER SAFETY WARNINGS

Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-Off Operations:
1.
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.
2.
Operations such as polishing are not recom-
mended to be performed with this power tool.
Operations for which the power tool was not
designed may create a hazard and cause personal
injury.
3.
Do not use accessories which are not specifi-
cally designed and recommended by the tool
manufacturer. Just because the accessory can be
attached to your power tool, it does not assure safe
operation.
4.
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.
5.
The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can-
not be adequately guarded or controlled.
6.
The arbour size of wheels, flanges, backing pads
or any other accessory must properly fit the
spindle of the power tool. Accessories with arbour
holes that do not match the mounting hardware of
the power tool will run out of balance, vibrate exces-
sively and may cause loss of control.
6
7.
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 accesso-
ries will normally break apart during this test time.
8.
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 vari-
ous operations. The dust mask or respirator must be
capable of filtrating particles generated by your oper-
ation. Prolonged exposure to high intensity noise
may cause hearing loss.
9.
Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
GEB033-6
personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away
and cause injury beyond immediate area of opera-
tion.
10. Hold the power tool by insulated gripping sur-
faces 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 elec-
tric shock.
11. Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
12. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the power
tool out of your control.
13. 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.
14. 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.
15. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
16. Do not use accessories that require liquid cool-
ants. Using water or other liquid coolants may result
in electrocution or shock.
