Grinding metals creates sparks that can ignite flammable materials and vapors.
Only grind metals if the area is free of combustible or explosive materials or vapors.
Explosions and fire can cause injury.
Overspeeding wheels can explode.
Check the speed rating of the accessory or the speed printed on the wheel.This speed must be greater than the nameplate speed
of the grinder and the actual speed of the grinder as measured with a tachometer. Do not exceed rated operating air pressure.
Exploding wheels can cause injury or death.
Power tools vibrate.
Excessive vibration can cause injury. If numbness, tingling, pain or whitening of the skin occurs, stop using tool and consult a
physician. See the tool’s information sheet for the vibration level.
Prolonged exposure to vibration can cause injury.
Grinders 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.
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.

Damaged grinding wheels can explode.
Check the wheel for damage before mounting, such as chips and cracks. Handle wheels carefully to avoid dropping or bumping.
Protect wheels from extremes of temperature and humidity. Check wheels immediately after any unusual occurrence that may
damage wheels. Check wheels daily. Hold tool under bench or provide other protection when starting up a new wheel, a used
wheel that has been remounted, or at the beginning of an operation. Run at operating speed in this protected area for at least
one minute before applying to the work. No one shall stand in front of or in line with the wheel during this test.
Exploding wheels can cause serious injury or death.
Flanges and other related mounting equipment in poor shape or not the proper ones for the wheel or tool used can cause wheels to
malfunction. Grinding wheels not properly tightened can spin off.
Be certain that all flanges and related mounting equipment are in good shape, the proper ones for the type and size of wheel
being used, and are securely fastened. Match wheel mounting hole to spindle size.
Grinding wheels that malfunction or spin off 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.
Abnormal sounding or excessively vibrating grinders can indicate a hazard that could cause wheel to explode.
If the normal sound of the grinder changes, or if it vibrates excessively, shut it off immediately, remove the wheel, and check
speed with tachometer. Tool could be overspeeding or the wheel could be damaged or not mounted properly.
Exploding wheels can cause injury or death.
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.
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.
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.
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.
Children in work areas can be injured.
Unauthorized or untrained personnel can misuse unattended tools.
Store idle tools in a dry, high or locked-up place, out of the reach of children.
Misused tools can cause injury.
Tools with the actuator left in the “ON” position when an unexpected air pressure loss occurs can start unexpectedly when the air
pressure is restored.
Release the actuator if an unexpected loss of air pressure occurs.
Unexpected tool starts can cause injury.
Grinders with the actuator left in the “on” position can cause unexpected starts when the tool is connected to the air supply.
Be sure actuator is off before hooking up air.
Unexpected starts can cause injury.
Grinders may coast for a short time after the trigger is released.
Be sure tool has come to a complete stop before setting it aside.

INTENDED USE
This tool is intended for use with Type 27 depressed center grinding wheels for metal removal.
It is not to be used with cone wheels, cup wheel or straight wheels.
THE GUARD MUST BE IN PLACE AT ALL TIMES!
AIR SUPPLY
The efficiency and life of this tool depend on the proper supply of clean, dry air at a maximum of 90 PSI. The use of an air line filter, pressure regulator, and
lubricator is recommended.
Before connecting to tools, blow out the air line to remove water and dirt that may have accumulated.
HOSE AND HOSE CONNECTIONS
The air supply hose recommended is 3/8” (10mm) I.D. If an extension hose is necessary, use 1/2" (13mm) ID hose with couplings not less than 3/8” (10mm)
I.D.
LUBRICATION
All models may operate without airline lubrication. However, operating the tool without airline lubrication may reduce tool performance and vane life.
If an airline lubrication is not used, it is recommended that the tool be oiled daily before use to improve performance. Add 2-4 drops of air motor oil and run the
tool for 10-20 seconds to distribute oil through the tool.
For maximum performance and tool life, an air line lubricator, set to deliver 2 drops per minute, is recommended. SIOUX No. 288 Air Motor Oil is
recommended.

Form Z823 3Date 2016November29/B
For Angle Head
Lubricate the angle head assembly with 2 shots of SIOUX #1232A grease every 8 working hours.
MAINTENANCE
Water, dust and other airline contaminants can cause rust and vane sticking. For long periods between tool use, flush the tool with a few drops of oil and run
for 10 seconds. This will help remove contaminants and reduce the formation of rust.
OPERATION
The tool is equipped with a locking type lever in order to prevent accidental start-up.
Speed of the tool may be adjusted by turning the regulator, which is located opposite the throttle lever.
The angle head can be repositioned by loosening the retaining collar and positioning the angle head in the desired position and retighten the retaining collar.
INSTALLING GRINDING WHEELS
Place Wheel Flange and wheel on spindle.
Thread Wheel Retainer onto spindle.
Tightened Wheel Retainer with enclosed spanner wrench while holding spindle with enclosed open end wrench. Tighten Wheel retainer to a maximum of 120
in-lb.
