Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating 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.
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. The operator can control
kickback forces, if proper precautions are taken.
b) 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.
c) Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of control.
d) Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direction
as the chips are thrown). Feeding the tool in the
wrong direction causes the cutting edge of the bit
to climb out of the work and pull the tool in the
direction of this feed.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications.
Additional Safety Warnings:
20. The tool is intended for use with bonded
abrasive wheel
permanently mounted on plain, unthreaded
mandrel (shanks).
21. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
22. 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.
23. Use the specified surface of the wheel to
perform the grinding.
24. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
points (grinding stones)
25. Do not leave the tool running. Operate the tool
only when hand-held.
26. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
27. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
28. Check that
supported.
29. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure
operator safety.
30. Do not use the tool on any materials
containing asbestos.
31. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.

1. Before using battery cartridge, read all
instructions and cautionary markings on (1)
battery charger, (2) battery, and (3) product
using battery.
2. Do not disassemble battery cartridge.
3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
4. If electrolyte gets into your eyes, rinse them
out with clear water and seek medical
attention right away. It may result in loss of
your eyesight.
5. Do not short the battery cartridge:
(1) Do not touch the terminals with any
conductive material.
(2) Avoid storing battery cartridge in a
container with other metal objects such
as nails, coins, etc.
