use. Clamping a small workpiece allows you to
use your hand(s) to control the tool. Round
material such as dowel rods, pipes or tubing have
a tendency to roll while being cut, and may cause
the bit to bind or jump toward you.
14. Position the cord clear of the spinning
accessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning accessory.
15. Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grab the surface and pull
the power tool out of your control.
16. After changing the bits or making any
adjustments, make sure the collet nut, chuck
or any other adjustment devices are securely
tightened. Loose
unexpectedly shift, causing loss of control, loose
rotating components will be violently thrown.
17. 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.
18. 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.
19. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
20. 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 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.
adjustment devices
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.
b) Do not position your hand in line with and
behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your
hand, the possible kickback may propel the
can spinning wheel and the power tool directly at you.
Additional safety warnings:
21. The tool is intended for use with bonded
abrasive
permanently mounted on plain, unthreaded
mandrel (shanks).
22. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
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. Use the specified surface of the wheel to
perform the grinding.
25. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
26. Do not leave the tool running. Operate the tool
only when hand-held.
27. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
28. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
29. Check that the workpiece is properly supported.
30. 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.
31. Do not use the tool on any materials
containing asbestos.
32. Always be sure you have a firm footing. Be sure no
one is below when using the tool in high locations.
