Keep your fingers and clothing away from the sanding
disc. Do not sand pieces that are so small that your fin-
gers touch the sanding disc while sanding. Don't use a
rag to hold workpiece while sanding. They could get cut
or wedged between the pad and the table.
Do not sand pieces of material that cannot be supported
by the table. When sanding larger workpieces provide
additional support at the sanding table height. Oversized
workpiece may cause the table to shift and you could lose
control.
Use miter fence when sanding. Supporting the workpiece
prevents it from being ejected from the sander and leaves
both hands to control the work.
Do not wet sand with this sander. A liquid entering the
motor housing is an electrical shock hazard.
Use special precautions when sanding chemically pres-
sure treated lumber, paint that may be lead based, or any
other materials that may contain carcinogens. All per-
sons entering the work area must wear a suitable breathing
respirator and protective clothing. Plastic sheeting should
seal Work area and persons not protected should be kept out
until work area is thoroughly cleaned.
Flex Shaft Safety Rules
Do not operate the flexible shaft with a sharp bend. Over
bending the shaft can generate excessive heat on the jacket
or hand piece. The recommended minimum is 6" radius.
Be aware of the switch location, when placing the flex
shaft down or when picking the tool up. You may acci-
dentally activate the switch.
Always hold the hand piece firmly in your hands during
the start-up. The reaction torque of the motor, as it acceler-
ates to full speed, can cause the shaft to twist.
After changing the bits or making any adjustments, make
sure the collet nut and any other adjustment devices are
securely tightened. Loose adjustment device can unex-
pectedly shift, causing loss of control; loose rotating compo-
nents will be violently thrown.
Do not reach in the area of the spinning bit. The proximi-
ty of the spinning bit to your hand may not always be obvious.
Allow brushes to run at operating speed for at least one
minute before using wheel. During this time no one is to
stand in front or in line with the brush. Loose bristles or
wires will be discharged during the run-in time.
Wear protective gloves and face shield with wire or bris-
tle brushes. Apply wire or bristle brushes lightly to the
work as only the tips of the wire/bristles do the work.
"Heavy" pressure on bristles will cause the wire or bristle to
become overstressed, resulting in a wiping action and will
cause the bristles/wire to be discharged.
Carefully handle both the tool and individual grinding
Specific Safety Rules
wheels to avoid chipping or cracking. Install a new wheel
if tool is dropped while grinding. Do not use a wheel that
may be damaged. Fragments from a wheel that bursts dur-
ing operation will fly away at great velocity possibly striking
you or bystanders.
Never use dull or damaged bits. Sharp bits must be han-
dled with care. Damaged bits can snap during use. Dull bits
require more force to push the tool, possibly causing the bit
to break.
Use clamps to support workpiece whenever practical.
Never hold a small workpiece in one hand and the tool in
the other hand while in use. Allow for sufficient space, at
least 6", between your hand and the spinning bit. Round
material such as dowel rods, pipes or tubing have a tenden-
cy to roll while being cut, and may cause the bit to "bite" or
jump toward you. Clamping a small workpiece allows you to
use both hands to control the tool.
Inspect your workpiece before cutting. When cutting
irregularly shaped workpieces, plan your work so it will
not slip and pinch the bit and be torn from your hand. For
example, if carving wood, make sure there are no nails or
foreign objects in the workpiece. Nails or foreign objects
can cause the bit to jump.
Never start the tool when the bit is engaged in the mate-
rial. Let the bit reach its full set speed before contacting
the workpiece. The bit cutting edge may grab the material
causing loss of control of the cutter.
Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can cause
loss of control and kickback.
The direction of feed with the bit into the material when
carving, routing or cutting is very important. Always feed
the bit into the material in the same direction as the cut-
ting 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.
If the workpiece or bit becomes jammed or bogged down,
turn the tool "OFF" by the switch. Wait for all moving
parts to stop and unplug the tool, then work to free the
jammed material. If the switch to the tool is left "ON" the tool
could restart unexpectedly causing serious personal injury.
Do not leave a running tool unattended, turn power off.
Only when tool comes to a complete stop it is safe to put it
down.
Do not grind or sand near flammable materials. Sparks
from the wheel could ignite these materials.
Do not touch the bit or collet after use. After use the bit
and collet are too hot to be touched by bare hands.
Do not allow familiarity gained from frequent use of your
rotary tool to become commonplace. Always remember
