General Operation
1. If you have just installed an accessory or are be-
ginning a period of work, test the wheel by letting it
spin for one minute before applying it to the work-
piece. WARNING! Never use a accessory that has
been dropped. Out-of-balance or damaged acces-
sories can mar workpiece, damage the tool, and
cause stress that may cause accessory failure.
2. Use a clamp, vise or other practical means to hold
the workpiece, freeing both hands to control the
tool.
3. WARNING! Hold tool securely with both hands.
Start the tool.
NOTE: If the battery is inserted when the tool is
ON, the tool will not run. Turn the tool OFF, then
back ON to begin work.
4. Allow accessory to come to full speed before
beginning work.
5. Control pressure and surface contact between ac-
cessory and workpiece. WARNING! Never bang
accessory onto work.Too much pressure causes
accessory failure or slows speed.
6. When nished, turn o the tool and make sure it
comes to a complete stop before laying it down.
Using Grinding Wheels
WARNING
The guard type must match the
wheel type to provide maximum
protection for the operator if the wheel should
break.
When grinding, hold tool at a 5⁰ to 15⁰ angle, using
constant pressure for a uniform nish. Too great an
angle causes concentrated pressure on small areas
which may gouge or burn work surface.
For best result use only this portion of disc
Hold at a
5° to 15° angle
Using Cut-O Wheels
Cut-O Wheels are suited for small cut-o and shal-
low notching operations only.
WARNING
The guard type must match the
wheel type to provide maximum
protection for the operator if the wheel should
break.
When using a cut-o wheel, hold the tool as shown,
using only the edge of the wheel. WARNING! Using
the face of a Cut-O Wheel (as in grinding) will cause
the Wheel to crack and break, resulting in serious
personal injury.
Using Wire Brushes
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc.
WARNING
Everyone in the area must wear
protective clothing and safety
goggles or face shields. Fatigued wires and
residue will y o the brush with considerable
force, causing potential for serious injury.
Never exceed Maximum Safe Operating Speed of
brush. Do not use a damaged brush or one that
is functioning improperly (throwing wires, out-
of-balance, etc.). These conditions increase the
possibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.
A Type "27" guard must be installed when using
a wire wheel brush to provide maximum protec-
tion for the operator when fatigued wires break.
(See "Removing/Installing/Adjusting the guard".)
Always install wire brushes according to the acces-
sory manufacturer’s instructions. Only use acces-
sories with threads matching the tool spindle.
