d. Store idle power tools out of the reach of children and do not
allow persons unfamiliar with the power tool or these instructions
to operate the power tool. Power tools are dangerous in the hands of
untrained users.
e. Maintain power tools. Check for misalignment or binding of
moving parts, breakage of parts and any other condition that may
affect the power tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused by poorly maintained
power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier to
control.
g. Use the power tool, accessories and tool bits etc., in accordance
with these instructions, taking into account the working conditions
and the work to be performed. Use of the power tool for operations
different from those intended could result in a hazardous situation.
SERVICE
a. Have your power tool serviced by a qualified repair person using
only identical replacement parts. This will ensure that the safety of the
power tool is maintained.
MULTITOOL SAFETY WARNINGS
SAFETY WARNINGS COMMON FOR
GRINDING, SANDING, WIRE BRUSHING,
POLISHING, CARVING OR ABRASIVE CUTTING-
OFF OPERATIONS
a. This power tool is intended to function as a grinder, sander, wire
brush, polisher, carving or cut-off tool. Read all safety warnings,
instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
b. Do not use accessories which are not specifically designed and
recommended by the tool manufacturer. Just because the accessory
can be attached to your power tool, it does not assure safe operation.
c. The rated speed of the grinding accessories must be at least
equal to the maximum speed marked on the power tool. Grinding
accessories running faster than their rated speed can break and fly
apart.
d. The outside diameter and the thickness of your accessory must
be within the capacity rating of your power tool. Incorrectly sized
accessories cannot be adequately controlled.
e. The arbour size of wheels, sanding drums or any other accessory
must properly fit the spindle or collet of the power tool. Accessories
that do not match the mounting hardware of the power tool will run out of
balance, vibrate excessively and may cause loss of control.
f. Mandrel mounted wheels, sanding drums, cutters or other
accessories must be fully inserted into the collet or chuck. If the
mandrel is insufficiently held and/or the overhang of the wheel is too
long, the mounted wheel may become loose and be ejected at high
velocity.
g. Do not use a damaged accessory. Before each use inspect the
accessory such as abrasive wheels for chips and cracks, sanding
drum for cracks, tear or excess wear, wire brush for loose or
cracked wires. If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After inspecting and
installing an accessory, position yourself and bystanders away
from the plane of the rotating accessory and run the power tool at
maximum no-load speed for one minute. Damaged accessories will
normally break apart during this test time.
h. Wear personal protective equipment. Depending on application,
use face shield, safety goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece fragments. The
eye protection must be capable of stopping flying debris generated by
various operations. The dust mask or respirator must be capable of
filtrating particles generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
i. Keep bystanders a safe distance away from work area. Anyone
entering the work area must wear personal protective equipment.
Fragments of workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
j. Hold power tool by insulated gripping surfaces only, when
performing an operation where the cutting accessory may contact
hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could
give the operator an electric shock.
k. Always hold the tool firmly in your hand(s) during the start-up.
The reaction torque of the motor, as it accelerates to full speed, can
cause the tool to twist.
l. 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. 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.
m. 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.
n. 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.
o. After changing the bits or making any adjustments, make sure
the collet nut, chuck or any other adjustment devices are securely
tightened. Loose adjustment devices can unexpectedly shift, causing
loss of control, loose rotating components will be violently thrown.
p. 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.
q. 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.
r. Do not operate the power tool near flammable materials. Sparks
could ignite these materials.
s. Do not use accessories that require liquid coolants. Using water
or other liquid coolants may result in electrocution or shock.
t. Use completely unrolled and safe extension cords with a capacity
of 5 Amps at least.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating wheel,
sanding band, 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. 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
