9. 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.
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 electric shock.
Position the cord clear of the spinning acces-
11.
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.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled 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
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 kick-
back forces, if proper precautions are taken.
b) Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
c) Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel's movement at the point of snagging.
d) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to snag
the rotating accessory and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades create
frequent kickback and loss of control.
Safety Warnings Specific for Grinding Operation:
a) Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
Safety Warnings Specific for Sanding Operations:
a) Do not use excessively oversized abrasive
disc. Follow manufacturers recommendations,
when selecting abrasive disc. Larger abrasive
disc extending beyond the pad presents a lacer-
ation hazard and may cause snagging, tearing of
the disc or kickback.
Additional safety warnings:
16. Always use a sanding disc or offset diamond
wheel specifically designed for wet operation.
17. Always install the dust cover before operation.
18. Ground Fault Circuit Interrupter (GFCI) pro-
tection should be provided on the circuit(s) or
outlet(s) to be used for the tool. Receptacles
are available having built-in GFCI protection
and may be used for this measure of safety.
19. For additional protection against electric
shock, be sure to WEAR RUBBER GLOVES
AND RUBBER BOOTS during operation.
20. When using the water feed, be careful not to let
water get into the motor. If water runs into the
motor, an electric shock hazard may result.
21. PROPER GROUNDING. This tool should be
grounding while in use to protect the operator
from electric shock.
22. EXTENSION CORDS. Use only three-wire
extension cords which have three-prong
grounding-type plugs and three-pole recepta-
cles which accept the tool's plug. Replace or
repair damaged or worn cord immediately.
23. Make sure the abrasive disc is not contacting
the workpiece before the switch is turned on.
24. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
25. Do not leave the tool running. Operate the tool
only when hand-held.
26. Do not touch the workpiece or the offset
diamond wheel immediately after operation;
it may be extremely hot and could burn your
skin.
27. Check that the workpiece is properly
supported.
28. Pay attention that the wheel continues to
rotate after the tool is switched off.
29. Do not use the tool on any materials contain-
ing asbestos.
