VARIABLE SPEED DIAL
Your sander is equipped with a variable speed

preset by rotating the dial to any of six
positions from 1 (8000 OPM) to 6 (11000
OPM).

more quickly.
• Lower speeds are especially appropriate
when sanding soft materials or thin veneers
to minimize the possibility of over sanding.
The best results will be obtained by sanding a
test sample of the workpiece material and
determining the best combination of sanding
speed and sanding sheet (sanding paper).
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.
ABRASIVE SHEETS (SANDPAPER)
Aluminum oxide, silicon carbide, or other
synthetic abrasives are recommended for
power sanding use. Natural abrasives, such as
flint or garnet sheet are too soft for economical
use in power sanding. For best results, use
Bosch abrasive sheets: The uniform spacing
between grains minimizes filling or loading.
