This tool is not insulated for contact with electric power sources.
Do not use near live electrical circuits or gas lines. When grinding, be aware that there might be hidden hazards such as gas
lines or electrical wires.
Electric shock can cause injury.
Slips, trips, and falls are major causes of workplace injury.
Be aware that the exhaust from this tool can cause slippery surfaces and the air hose can present a trip hazards. Proceed with
care in unfamiliar surroundings. Grinder should not be used in explosive atmospheres and is not insulated against contact with
electrical current.
In addition, proceed with care in unfamiliar surroundings as there can be hidden hazards.
Operating this grinder can create hazards.
Avoid contact with the spindle and mounted grinding wheel. Operators and maintenance personnel should be physically able to
handle the bulk, weight and power of the grinder. Hold the tool firmly and be ready to counteract normal or sudden movements
of the tool. Release the start-stop device in the case of an interruption of the energy supply. Use only lubricants suggested by
Sioux Tools. Wear a safety helmet for overhead work. When finished using the grinder, wait for the wheel rotation to stop and
place it in a stable position. The operator should make sure no bystanders are in the vicinity during operation. Wear personal
protective equipment such as gloves, apron and helmet. Ensure sparks do not land on clothing or flammable surfaces. Wear
fire-retardant clothing and have a bucket of water nearby.
Improper operation of the grinder can cause injury.
Maintain and replace inserted tools as recommended in order to prevent an increase in dust, noise and vibration.
This tool is not intended for use in a flammable or explosive atmosphere.
Do not use this tool in a flammable or explosive atmosphere.
Explosions and fire can cause injury.
Using excessive force on a tool makes it hard to control.
Do not force tool.
Hard to control tool can casue 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.
Operators and maintenance personnel shall be physically able to handle the weight and power of the tool.
All tools that are supplied with an auxiliary handle should only be used when that handle is in place and secured.
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.
Unexpected tool failures 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. Air under pressure can cause severe injury.
Never direct air at yourself or anyone else. Cold air such as exhaust air should always be directed away from the hands. Never
carry a tool by its hose. Whenever universal twist couplings (claw couplings) are used, lock pins shall be installed and whip
check safety cables shall be used to help prevent possible hose-to-tool and hose-to-hose 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.
Erratic operation in power tools can cause injury.
Improperly repaired tools perform unpredictably.
Do not modify the tool. Repair tools at an Authorized Sioux Service Center. Never use a damaged or modified tool.
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. Release the trigger in the case of an interruption of air supply.
Tools starting unexpectedly and flying keys and wrenches can cause injury. Always ensure that the work piece is securely fixed.
Working in poorly lit areas makes it hard to see hazards.
Keep work area well lit.
Poorly lit work areas can cause injury.
Grinder accessories may cause hazards.
Disconnect the air line before exchanging an accessory or abrasive tool. Ensure that the dimensions of the abrasive product
are compatible with the grinder and that the abrasive product fits the spindle. Inspect the abrasive product before use. Do
not use abrasive products which can have possible been dropped or which are damaged. Ensure that the abrasive product is
correctly mounted and tightened before use. Run grinder at no-load speed for at least 1 minute in a safe position. Stop use if
considerable vibration or other defects are detected. Where abrasive products are supplied or used with reducing adapters or
bushings, the user shall ensure that the adapter or bushing does not contact the face of the flange and that the clamping force
provides sufficient rotational driving action. Always fit the correct flanges for the abrasive being used. Avoid direct contact with
the inserted tool during and after use as it can become hot or sharp.
Store and handle the abrasive product with care.
Children are attracted to work areas.
Keep children away. All visitors must keep a safe distance away from work area.
Children in work areas can be injured.
