INTENDED USE
This tool is intended for use with small mounted abrasive wheel for precision material removal.
Mounted wheels are defined as abrasive wheels that are secured to plain or threaded mandrels.
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.
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 die grinder operates in the clockwise direction when viewed from the operator’s position.
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.
INSTALLING MOUNTED WHEELS
Insert the mounted wheel into the collet. Make sure the wheel shank and the collet size match. Do not allow the wheel to extend beyond the collet an excessive
distance.
Hold the collet body with a 9/16” (14mm) wrench and the collet nut with a 3/4” (19 mm) wrench.
Turn the collet nut to the right and firmly tighten the collet on to the wheel shank.
REMOVING MOUNTED WHEELS
To remove the mounted wheel, hold the collet body with a 9/16” (14 mm) wrench and the collet nut with a 3/4” (19 mm) wrench.
Turn the collet nut to the left and loosen the collet.
Remove the mounted wheel.
WARNING
Disconnect tool from air supply before installing or removing wheel or making any adjustments
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.
Grinders that do not come to a complete stop before setting aside can cause injury.
Cut off wheels or router bits are not rated for the high speed of die grinders and could explode or fly apart.
Do not use cut off wheels or router bits with die grinders.
Exploding or flying parts can cause injury.
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.
The use of any accessory with this tool not provided or specified by Sioux Tools can perform unpredictably.
Use only accessories provided or specified by Sioux Tools.
Tools that perform unpredictably can cause injury.
When disposing of a tool, do it in a way that does not harm personnel or the environment.
