12. 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.
13. 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.
14. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
15. Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
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 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 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. 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.
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.
Additional safety warnings:
16. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
17. Check that the workpiece is properly supported.
18. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
19. Keep hands away from rotating parts.
20. Do not touch the workpiece immediately after
operation; it may be extremely hot and could burn
your skin.
21. Always be sure you have a firm footing. Be sure
no one is below when using the tool in high
locations.
22. Do not use the tool on any materials containing
asbestos.
23. 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.
24. 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.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action (Fig. 1)
CAUTION:
• Before plugging in the tool, always check to see that
the switch lever actuates properly and returns to the
“OFF” position when released.
• Do not pull the switch lever forcibly without pushing in
the lock-off lever.
For tool with lock button
To prevent the switch lever from accidentally pulled, a
lock-off lever is provided. To start the tool, pull the lock-off
lever toward the operator and then pull the switch lever.
Release the switch lever to stop. For continuous
operation, pull the switch lever and then push in the lock
button. To stop the tool from the locked position, pull the
switch lever fully, then release it.
For tool without lock button
To prevent the switch lever from accidentally pulled, a
lock-off lever is provided. To start the tool, pull the lock-off
lever toward the operator and then pull the switch lever.
Release the switch lever to stop.
