OPERATION
WARNING
To reduce the risk of injury, always
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.
WARNING
Always hold the tool firmly with
both hands using the handles
provided before and during grinding.
Paddle Switch Operation
To
start
the tool, grasp the handle and side handle
firmly. Push the lock-off button forward and squeeze
the paddle switch.
To
stop
the tool, release the paddle switch. Make
sure the tool comes to a complete stop before laying
down the tool.
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.
If the tool stalls, release the trigger to reset. Lighten
pressure to avoid stalling.
6. When finished, turn off 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 5
o
to 15
o
angle, using
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
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.
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-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.
WARNING
Everyone in the area must wear
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.
