WARNING:

Important safety information en­closed.
Read this manual before operating
tool.
It is the responsibility of an em­ployer to place the information in
this manual into the hands of any­one who operates this device.
Failure to observe the following
warnings could result in injury.

SANDER SPECIFIC
WARNINGS

• These Sanders will operate at
the free speed specified on the
label if the air supply line fur­nishes 90 psig (6.2 bar/620
kPa) air pressure at the tool.
Operation at higher air pressure
will result in excessive speed.

• Use only a sanding pad, buffing
wheel or polishing bonnet with
these tools. Do not use any
grinding wheel, bur or metal
removing accessory with these
tools. Never use an accessory
having a maximum operating
speed less than the free speed
of the Sander in which it is
being used.

• When using a pad having a
shank, insert the shank to full
depth in the collet. When using
a pad on a threaded arbor,
make certain the flange nut is
tightened securely. Check the
tightness of the collet nut or
flange nut before operating a
Sander to make certain it will
not loosen during operation.

NOTICE: The use of other than

genuine Craftsman replacement
parts may result in safety hazards,
decreased tool performance, in­creased maintenance, and may
invalidate all warranties.

Repairs should be made only by
authorized trained personnel.

PLACING TOOL IN SERVICE

• Always operate, inspect and
maintain this tool in accordance
with all regulations (local, state,
federal and country), that may
apply to hand–held/hand–oper­ated pneumatic tools.

• For safety, top performance,
and maximum durability of
parts, operate this tool at
90 psig (6.2 bar/620 kPa) maxi­mum air pressure at the inlet
with 5/16” (8 mm) inside diame­ter air supply hose.

• Always turn off the air supply
and disconnect the air supply
hose before installing, removing
or adjusting any accessory on
this tool, or before performing
any maintenance on this tool.

• Do not use damaged, frayed or
deteriorated air hoses and fit­tings.

• Be sure all hoses and fittings
are the correct size and are
tightly secured. See Figure 4,

arrangement.

• Always use clean, dry air at
90 psig maximum air pressure.
Dust, corrosive fumes and/or
excessive moisture can ruin the
motor of an air tool.

Air Supply and Connections

Always use clean dry air. Dust,
corrosive fumes and/or excessive
moisture can ruin the motor of an
air tool. An air line filter can greatly
increase the life of an air tool.

The filter removes dust and mois­ture. Be sure all hoses and fittings
are the correct size and are tightly
secured. See Figure 4 for a typical
piping arrangement.
