OPERATION
To reduce the risk of injury, always
WARNING
wear safety goggles or glasses
with side shields. Never grind without proper
safety equipment.
Controlled Start
The controlled start feature reduces the torque reac-
tion "jerk" when the trigger is pulled.
Always hold the tool firmly with
WARNING
both hands using the handles
provided before and during grinding.
Paddle Switch Operation
To start the tool, grasp the handle and side handle
firmly. Pull the lock-off button back and squeeze the
paddle switch.
To stop the tool, release the paddle switch. Make
sure the tool comes to a complete stop before laying
the tool down.
General Operation
1. If you have just installed an accessory or are
beginning a period of work, test the wheel by let-
ting it spin for one minute before applying it to the
workpiece. WARNING! Never use a accessory
that has been dropped. Out-of-balance or dam-
aged accessories 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
your work, 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 finished, turn off the tool and make sure it
comes to a complete stop before laying it down.
Using Grinding Wheels
The guard type must match the
WARNING
wheel type to provide maximum
protection for the operator if the wheel should
break.
When grinding, hold tool at a 5
constant pressure for a uniform finish. 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
to 15 angle, using
o o
Hold at a
5° to 15°
angle
Using Cut-Off Wheels
Cut-Off Wheels are suited for small cut-off and shal-
low notching operations only.
The guard type must match the
WARNING
wheel type to provide maximum
protection for the operator if the wheel should
break.
When using a cut-off wheel, hold the tool as shown,
using only the edge of the wheel. WARNING! Using
the face of a Cut-Off 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.
Everyone in the area must wear
WARNING
protective clothing and safety
goggles or face shields. Fatigued wires and
residue will fly off 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.
Guard
Test wheel for balance and loose or damaged wires
by letting it spin for one minute before applying it to
the workpiece. During this time, no one should stand
in front of or in line with it.
