Backing Pad Installation
The random orbit sander is equipped with a
backing pad of medium hardness, which is
suitable for general service. Hard and extra-
soft pads are available for other purposes,
and in general are used as follows;
Soft pad - Polishing or sanding large or
curved surfaces.
Medium pad - All purpose general sanding
and polishing.
Hard pad - Heavy sanding on flat surfaces,
especially with coarser abrasives.
This sander is unique in that it can accept
either 5" or 6" (Bosch) pads.
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).
Installing Accessories
The random orbit sander uses hook-and-
loop backed accessories, which firmly grip
the pad when applied with moderate
pressure. To change the accessory, merely
peel off the old accessory, remove dust
from the pad if necessary, and press the
new accessory in place (Fig. 3). Be sure to
align the sanding disc holes with the holes
in the backing pad to allow the dust
extraction system to function.
After considerable service the pad surface
will become worn, and the pad must be
replaced when it no longer offers a firm
grip. If you are experiencing premature
wearout of the pad hooks, it may be due to
pressure being applied to the tool during
operation.
Front Handle
Your sander is equipped with a removable
front handle when sanding in tight quarters.
To remove handle, remove screw with 5 mm
hex wrench. Always reinstall handle for
normal operation (Fig. 1).
Depending on the task, you may grip the
rear handle alone, the rear handle and the
front handle, or the rear handle and the top
of the ergonomically contoured soft grip
motor housing, which is designed for that
purpose.
