Sanding operations
Once the machine and vacuum cleaner are set up and all safety measures and equipment
are in place, begin by turning on the vacuum cleaner and then the machine. (If you are
using a vacuum cleaner with integrated switching, then simply turn the machine on)
Begin sanding and carefully contact the work surface as lightly as possible - just enough to
keep the sanding head flat against the surface.
The joints in the sanding head allow the sanding disc to follow the contours of the work
surface.
The best technique is to use overlapping sweeps and keep the head in constant motion.
Never stop too long on 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
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.
The carbon brushes furnished will last approximately 50 hours of running time or
10.000 on/off cycles.
Replace both carbon brushes when either one has less than ¼” length of carbon
remaining.
To inspect or replace brushes, first unplug the machine.
Carefully remove the 14 screws on the right side to remove the right hand side only
handle and motor covers. Leave the left hand covers in place. The vacuum swivel
connector will also come apart when this is done.
