OPERATION
To reduce the risk of injury, always
WARNING
wear safety goggles or glasses
with side shields. Never grind without proper
safety equipment.
Starting and Stopping the Motor
1. To start the tool, pull the trigger.
2. To stop the tool, release the trigger.
Always hold the tool firmly with
WARNING
both hands using the handles
provided before and during grinding.
To reduce the risk of injury or damage to the
tool, do not use the spindle lock button to stop
the spindle while the tool is in use or is coasting
after shut-off.
Locking the Trigger (Select Models)
The lock button holds the trigger in the ON position
for continuous use.
1. To lock the trigger on, hold in the lock-on button
while pulling the trigger. Release the trigger.
2. To unlock the trigger, pull the trigger and release.
The lock-on button will pop out.
Using the Dial Speed Control
(Cat. No. 6078 only)
Cat. No. 6078 has a dial speed control and variable
speed trigger switch. The maximum speed may be
preset using the speed control dial and the speed
may be varied by the trigger switch. Speed control
dial settings range from 1 to 5. Lower numbers
correspond to lower speeds and higher numbers
correspond to higher speeds. Use the setting that
best suits the work.
To control the speed, set the dial to the desired
number. Then, pull the trigger. Increase or decrease
pressure on the trigger to vary the speed. To stop the
tool, release the trigger.
General Operation
1. If you have just installed an accessory or are
beginning a period of work, test the wheel by
letting it spin for one minute before applying it to
the workpiece. WARNING! Never use a grinding
wheel that has been dropped. Out-of-balance or
damaged accessories can mar workpiece, dam-
age 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.
4. Allow accessory to come to full speed before
beginning work.
5. Control pressure and surface contact between
accessory and workpiece. WARNING! Never
bang grinding wheel 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 Sanding Discs
Hold tool at 5° to 15° angle to ensure proper sanding
pressure and control. Too great an angle will result
in too much pressure and could cause excessive
wear to the disc and workpiece. Too small an angle
will reduce control.
Use long, sweeping, side to side strokes, advancing
forward to produce the desired finish.

For best results, use only this portion of the disc.
Cross Sanding - When finishing a surface that
has been prepared by a coarse disc or wheel, sand
at right angles to the strokes made by the coarser
disc. Finishing marks left from previous sanding are
easily seen and removed for a uniform finish. Failure
to cross sand when changing from a coarse disc to
a finishing disc may result in deep scratches and
circular marks.
Removing Welds or Hammer Marks - When remov-
ing welds or hammer marks, limit coarse sanding to
the immediate area. Use successively finer grits to
smooth surface.
Finishing Metal - Constantly move across the sur-
face. Work faster on curved surfaces where contact
areas are smaller and pressure is greater. Flat areas
may appear at the end of the stroke when pressure
is too heavy. Ease up on pressure at end of each
stroke and when reversing strokes.
Deep scratches and circular marks can result from:
• Using too coarse a grit
• Using a partially glazed disc
• Dirt or loose metal on the workpiece
• Failure to sand across the grain when changing from
coarse to finishing discs
• Failure to use closed coated discs to reduce the
problem of grains working loose and scratching the
workpiece
Bluish discoloration of metal surface indicates:
• Excessive heat caused by circular motion in a small area
• Excessive pressure
• Use of worn out or glazed discs
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.
