BACKING PAD INSTALLATION
The random orbit sander is equipped with a
backing pad of soft hardness, which is suitable
for general service. Hard and extra-soft pads
are available for other purposes, and in
general are used as follows;
Extra soft pad - Polishing or sanding large or
curved surfaces.
Soft pad - All purpose general sanding and
polishing.
Hard pad - Heavy sanding on flat surfaces,
especially with coarser abrasives.
To change backing pad, hold pad firmly and
remove the screw using a 5 mm hex wrench
that secures the backing pad and remove old
pad. Align new pad over drive gear on drive
spindle. Attention: always be sure the teeth
on the drive gear engage into the openings on
the backing pad. Replace screw and securely
tighten. Damaged or worn backing pads must
be replaced immediately (Fig. 2).
