14. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
15. Do not use accessories that require liquid cool-
ants. Using water or other liquid coolants may result
in electrocution or shock.
16. 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 sur-
face 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
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back 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 snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating
accessory and cause loss of control or kickback.
17. Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
for your power tool.
b) Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them
to shatter.
c) Always use undamaged wheel flanges that
are of correct size and shape for your
selected wheel. Proper wheel flanges support
the wheel thus reducing the possibility of wheel
breakage.
d) Do not use worn down wheels from larger
power tools. Wheel intended for larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
18. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
19. Check that the workpiece is properly supported.

20. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
21. Keep hands away from rotating parts.
22. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
23. Always be sure you have a firm footing. Be sure
no one is below when using the tool in high loca-
tions.
24. Do not use the tool on any materials containing
asbestos.
25. 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.
26. Do not use this tool as cutter.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
OPERATING INSTRUCTIONS
Installing or removing wheel point (Fig. 1 & 2)
Important:
• Always be sure that the tool is switched off and
unplugged before installing or removing the wheel
point.
Loosen the collet nut and insert the wheel point into the
collet nut. Use the smaller wrench to hold the spindle and
the larger one to tighten the collet nut securely.
The wheel point should not be mounted more than 8mm
from the collet nut. Exceeding this distance could cause
vibration or a broken shaft.
To remove the wheel point, follow the installation proce-
dure in reverse.
CAUTION:
Use the correct size collet cone for the wheel point which
you intend to use.
Switch action (Fig. 3)
CAUTION:
Before plugging in the tool, always check to see that the
switch actuates properly and returns to the "OFF" posi-
tion when the side of the switch lever is depressed.
To start the tool, slide the switch lever toward the "I" posi-
tion. For continuous operation, press the front of the
switch lever to lock it. To stop the tool, press the rear of
the switch lever, then slide it toward the "O" position.
