SANDER/POLISHER SPECIFIC WARNINGS
These Sanders and Polishers will operate at the free
speed specified on the nameplate 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 other than
a sanding pad with these tools. Never use an
accessory having a maximum operating speed less
than the free speed of the Sander or Polisher in
which it is being used.
When using a pad on a threaded arbor, make
certain the flange nut is tightened securely. Check
the tightness of the flange nut before operating a
Sander to make certain it will not loosen during
operation.
WARNING: Incorrect combinations of grinding wheel, wheel guard and tool speed could result in injury.
Correct combinations are specified below:
