Backing pads rotating at excessive speed can burst.
Check the speed printed on the backing pad. This speed must be greater than the nameplate speed of
the sander. Do not exceed rated operating air pressure.
Bursting backing pads can cause injury or death.
Sanders are not guarded for use with grinding wheels or cut off wheels.
Never mount a grinding wheel or cutoff wheel on a sander.
Unguarded grinding wheels and cut off wheels can cause injury.
Sanders can generate unexpected movement.
Keep a fi rm grip on the tool at all times. Be sure your body position allows you to have control of the
tool at all times. Make sure your footing is secure. When possible, secure the work piece in a vice or
with clamps.
Unexpected tool movement can cause injury.
Using excessive force on a tool makes it hard to control.
Do not force tool.
Hard to control tool can cause injury.
Taping or wiring the throttle valve in the "ON" position will prevent the tool from shutting off if the tool should
jam or malfunction or if anything unexpected happens.
Do not wire or tape down the "On-Off" valve of any power tool.
Tools that are prevented from shutting off can cause injury.
Poorly maintained and lubricated tools can fail unexpectedly.
Keep tool properly lubricated and in good repair at all times. Use only Sioux Air Motor Oil No. 288. See
the tool's information sheet to fi nd out what other greases and oils to use. Do not drop the end of the
hose on the fl oor where it will pick up dirt and transport it into the tool. See information sheet for any
additional maintenance requirements.
Unexpected tool failures can cause injury.
Backing pads, sanding discs and related equipment in poor shape or not the proper ones for the tool can
cause the tool to malfunction. Backing pads not properly tightened can spin off. Sanding disc not properly
attached can spin off. Dust collection equipment not properly attached can come off.
Be certain that all backing pads, sanding discs and related equipment are in good shape, the proper
ones for the type and size of tool being used, and are securely fastened.
Backing pads and sanding discs that spin off can cause injury. Dust collection equipment that comes off can
cause injury.
Sanding discs mounted off-center can expose an excessive portion of the edge and cause vibration.
Make sure the sanding disc is mounted concentrically on the backing pad.
Excessively exposed portions of the sanding disc can cause injury. Excessive vibration can cause injury.
Air hoses can come loose from power tools and whip.
Inspect and do not use tools with loose or damaged air hoses or fi ttings.
Whipping air hoses can cause injury.
Air hoses that are not oil resistant or are not rated for the working pressure can burst.
Make sure that all air hoses are oil resistant and rated for the working pressure.
Air hoses that burst can cause injury.
Tools not operated at proper air pressure can operate erratically.
Do not exceed a maximum air pressure of 90 psig/6.2 bar or as stated on the tool's nameplate or
operating instructions. Use an air regulator to maintain proper air pressure.
Erratic operation in power tools can cause injury.
Improperly repaired tools perform unpredictably.
Repair tools at an Authorized Sioux Service Center.
