•
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.
•
Hold the power tool by the insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden wiring or its own cord. A
cutting accessory contacting a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an electric shock.
•
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.
•
Use clamps to support the 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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
Do not operate the power tool near flammable materials. Sparks could ignite these
materials.
•
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, 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.
•
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.
•
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.
•
Do not attach a toothed saw blade. Such blades create frequent kickback and loss of
control.
•
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.
