Never stop too long in any one place or there
will be swirl marks. With experience it will be
very easy to create excellent results.
NOTE: Ensure that the sandpaper you are using is
suited to the task. Overly coarse grit paper may
remove material too quickly to control. While
overly fine grit paper may clog too often and not
shape down the surface.
CAUTION: Take care to avoid pointed projections
and nails, etc. This will wipe out the sandpaper
and probably damage the sponge pad as well.
MAINTENANCE
Every 50 hours of operation blow compressed air
through the motor while running at no load to clean
out accumulated dust. (If operating in especially
dusty conditions, perform this operation more
often.)
KEEP TOOL CLEAN
Periodically blow out all air passages with dry
compressed air. All plastic parts should be cleaned
with a soft damp cloth. NEVER use solvents to clean
plastic parts. They could possibly dissolve or
otherwise damage the material.
Wear safety glasses while using compressed air.
Clean the vacuum swivel connector as too much
dust will keep it from turning freely.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
When the brushes are worn to a length of 1/4", they
should be replaced.
NOTE: Checking and replacing the carbon
brushes should be entrusted to a qualified
service center.
TO CHANGE THE BRUSHES
1. Unplug the machine.
2. Remove the brush cap with a slothead
screwdriver
3. Remove the brush.
4. Install new brushes in reverse order and replace
covers
If the replacement of the power supply
cord is necessary, this has to be done by the
manufacturer or their agent in order to avoid a
safety hazard.
WARNING: All repairs must be entrusted to an
authorized service center. Incorrectly performed
repairs could lead to injury or death.
