WARNING
Disconnect tool from air supply before installing or removing wheel or making any adjustments
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.
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. Periodically check the speed and vibration of the grinder. If the speed
exceeds the nameplate speed, have grinder repaired. Verify all safety markings are legible. Inspect spindle threads, clamping devices and abrasive location
features for wear. If wear is present, replace components.
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.
