Sanding Disc Selection
Use sanding discs and accessories that are:
• correct size as written on tool's nameplate.
• rated at or above the RPM listed on the tool's name-
plate.
• correct accessory, wheel type and grit for the job.
Select the correct type of sanding disc for your job.
Generally, use 24 or 36 grit for heavy stock removal;
50, 60, or 80 grit for medium stock removal and 120
grit for finishing. Always begin with a coarse grit, us-
ing successively finer grits to obtain the desired finish.
•Aluminum Oxide: For fast cutting, general purpose
discs for most metal jobs. Best for cold-rolled steel,
stainless steel or metals requiring tough, fast cutting,
long lasting abrasives.
•Aluminum Zirconia Bi-Cut: Unique grit pattern is
arranged in clusters for faster stock removal and
cleaning. Ideal for removing paint from cars, boats,
etc. without clogging.
•Ceramic: Lasts up to 3 times longer than Aluminum
Oxide Discs. For general metal working. Ideal for
tough jobs.

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.
