Sanding belts 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. Never run the tool unless the abrasive is applied to the work piece.
Bursting sanding belts 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 firm 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. Hold the tool correctly; be ready to
counteract normal or sudden movements and have both hands available. Maintain a balanced body position with secure footing.
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 find out what other greases and oils to use. Do not drop the end of the hose on the floor where it will pick up dirt and
transport it into the tool. See information sheet for any additional maintenance requirements. Never run the tool unless the
abrasive is applied to the work piece.
Unexpected tool failures can cause injury.
Abrasive belts and related equipment in poor shape or not the proper ones for the tool can cause the tool to malfunction. Abrasive
belts not properly mounted can spin off. Sanding disc not properly attached can spin off. Dust collection equipment not properly
attached can come off.
Be certain that all sanding belts, 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. Select, maintain, and replace the consumables as recommended by the supplier.
Sanding belts and sanding discs that spin off can cause injury. Dust collection equipment that comes off can cause injury. Tools should
be periodically inspected to ensure ratings and markings are legible. Replace labeling as needed. Avoid exposure to hazardous
substances deposited on the tool.
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. Inspect the belt before each use. Do not use if
cracked or broken or if it has been dropped.
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 fittings.
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. When universal twist couplings are used, lock pins
shall be installed and whipcheck safety cables shall be used to safeguard against hose-to-tool or hose-to-hose connection failure.
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. Air pressure should be checked at the point where air enters the tool while the tool is
running. Speed should be checked while the tool is running maximum free speed at maximum air pressure (90 psig/6.2 bar). Check
operating pressure and freespeed after any maintenance, repairs, or potentially damaging events to verify safe operating conditions.
Erratic operation in power tools can cause injury.
Improperly repaired tools perform unpredictably.
Repair tools at an Authorized Sioux Service Center. Only qualified and trained operators should install, adjust, or use the sander.
Tools that perform unpredictably can cause injury.
Tools left connected to the air supply can start unexpectedly.
Always remove tool from air supply and activate trigger to bleed air line before making any adjustments, changing accessories,
or doing any maintenance or service on tool. Make it a habit to check to see that all adjusting keys and wrenches have been
removed from tool before turning it on. Never carry an air tool by the hose. Avoid direct contact with accessories during or after
use, as they may be hot or sharp. When using a sander or polisher to perform work-related activities, the operator can experience
discomfort in the hands, arms, shoulders, neck or other parts of the body. Air under pressure can cause severe injury.
Tools starting unexpectedly and flying keys and wrenches can cause injury.
Working in poorly lit areas makes it hard to see hazards.
Keep work area well lit. For overhead work, wear a safety helmet. Slips, trips, and falls are a major cause of workplace injury. Be
aware of slippery surfaces caused by use of the tool; and the trip hazards cause by the air hose. Consider risks to bystanders.
While using a sander or polisher, the operator should adopt a comfortable posture whilst maintaining secure footing and
avoiding awkward or off-balance postures. The operator should change posture during extended tasks; this can help avoid
discomfort and fatigue.
Poorly lit work areas can cause injury.
Children are attracted to work areas.
Keep children away. All visitors must keep a safe distance away from work area. Exhaust air can be extremely cold or
contaminated. Never direct air at yourself or anyone else. Use appropriate precautions.
Children in work areas can be injured.
Unauthorized or untrained personnel can misuse unattended tools.
Do not operate tools without professional guidance. Store idle tools in a dry, high or locked-up place, out of the reach of children.
If the operator experiences symptoms such as persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness,
burning sensations or stiffness, these warning signs should not be ignored. The operator should tell the employer and consult a
qualified health professional.
Misused tools can cause injury.
