devices are securely tightened. Loose adjustment devices can unexpectedly shift, causing loss of control, and 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.
Instruction that the maximum recommended diameter of mounted wheels, threaded cones and plugs shall not
exceed 2 3/16” (55 mm) and that the maximum recommended diameter of sanding accessories shall not exceed 3
1/8” (80 mm).
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.
• When using rotary files, cut-off wheels, high-speed cutters or tungsten carbide cutters, always have the work
securely clamped. These wheels will grab if they become slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself usually breaks. When a rotary file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from the groove and you could lose control of the tool.
SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE CUTTING-OFF
OPERATIONS:
Use only wheel types that are recommended for your power tool and only for recommended applications. For
example: do not grind with the side of a cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding,
side forces applied to these wheels may cause them to shatter.
For threaded abrasive cones and plugs use only undamaged wheel mandrels with an unrelieved shoulder flange
that are of correct size and length. Proper mandrels will reduce the possibility of breakage.
