Preparing For Operation
Note:
This sander is designed for use on plastic and wood surfaces only. Do not use this sander for sanding
metals. Sanding metals will cause sparks that will ignite wood and dust particles on sander, in the dust
collector, or in workshop.
It is recommended that this tool not be used for extended work on any berglass or abrasive materials.
It has been found that those materials are subject to accelerated wear and possible premature failure,
as the berglass chips and grindings are highly abrasive to bearings, brushes, commutator, etc. During
any sanding of these materials, it is important the tool be cleaned frequently by blowing with an air
jet.
Do not use sander without a sand belt. Doing so will damage the rotating axle.
Make sure nut on the top of the rotating axle is tightened securely - but not overtightened.
SAND BELT SELECTION
Selecting the correct size diameter, type of grit and sanding sleeve is an extremely important step in achieving a
high quality nish:
Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding.
Natural abrasives, such as int and garnet are too soft for use in power sanding.
Select and install the desired sand belt for the particular application. Sand belts from 3/4”- 2” can be used with this
sander. Choose one that is close in size to the material you are sanding.
GRIT SELECTION
The condition of the surface to be sanded will determine which grit will do the proper job. In general, coarse grit will
remove the most material. Finer grit will produce the best nish in all sanding operations. If the surface is rough,
start with a coarse grit and sand until the surface is uniform. Medium grit may then be used to remove scratches
left by the coarser grit and ner grit used for nishing of the surface. Always continue sanding with each grit until
the surface is uniform.
WARNING! Do not use water with this sander. It is for dry
sanding only. Wet sanding will damage the machine,
and may present a shock hazard. Use only in dry
locations.
