INSTALLING SANDING BANDS
Loosen the screw on the top of the sanding drum using the end of
the wrench to contract the width of the drum. Slide the sanding band
onto the sanding drum. Fully tighten the screw to expand the width of
the sanding drum to hold the sanding band in place. Make sure the
sanding drum is sufficiently expanded to secure the band during use.
If sanding band is loose on the drum, it may fly off during operation
and cause injuries.
INSTALLING FELT POLISHING ACCESSORIES
Thread the felt polishing accessory straight down onto the tip of the
screw mandrel. The accessory must be threaded all the way down to
touch the collar of the screw mandrel.
IMPORTANT:
Before operation, check to make sure that
all accessories are assembled correctly and securely.
