KNOW HOW TO USE TOOL

= Use right tool for job. Do not force tool or attachment to do

a job for which it was not designed.

• Disconnect tool when changing belt or abrasive disc.

• Avoid accidental start-up. Make sure that the tool is in the
"OFF" position before plugging in.

• Do not force tool. It will work most efficiently at the rate for
which it was designed.

• Keep hands away from moving parts and sanding surfaces.

• Never leave tool running unattended. Turn the power off
and do not leave tool until it comes to a complete stop.

• Do not overreach. Keep proper footing and balance.

° Never stand on tool. Serious injury could occur if tool is

tipped or if belt or disc are unintentionally contacted.

• Know your tool. Learn the tool's operation, application and
specific limitations.

• Use recommended accessories (refer to page 15). Use of
improper accessories may cause risk of injury to persons.

• Handle the workpiece correctly. Protect hands from possi-
ble injury.

• Turn machine off if it jams. Belt jams when it digs too
deeply into workpiece. (Motor force keeps it stuck in the
work.)

• Support workpiece with miter gauge, belt platen or work
table.

° Maintain V_J'maximum clearance between table and sand-

ing belt or disc.

CAUTION: Think safety! Safety is a combination of operator
common sense and alertness at all times when tool is being

used.

DESCRIPTION

The Craftsman Belt and Disc Sanders are constructed of
rugged die cast aluminum and cast iron providing stability and

vibration-free operation. The belt and disc are used to sand,

deburr, bevel and grind large workpieces of wood and plastic.
The belt housing can be pivoted from vertical to

horizontal for sanding large, straight workpieces. The idler
drum permits the sanding of contoured shapes and finishes.

The disc can be used to sand or bevel surfaces.
Built-in dust collection system collects dust from the belt and

disc, and exhausts the dust into an included 30-micron
collection bag.

The adjustable miter gauge can be used on both the belt and
disc tables for guiding the workpiece at a desired angle while
sanding. Work stop included for sanding long pieces on the
