Read and understand
"Safety Instructions For Air Tools"
and these instructions before
operating this tool.
AIR SUPPLY
The efficiency of the tool is dependent on the proper supply of clean dry air at 90 psig (6.2 bar). The use of a line filter, pres
-
sure regulator, and lubricator will insure maximum output and life of tools. Before connecting tool, blow out the air line to
remove water and dirt which may have accumulated.
HOSE AND HOSE CONNECTIONS
Supply hose should be not less than 1/4" (6.4 mm) I.D. Extension hoses should be at least 3/8" (10 mm) I.D. Use couplings
and fittings with at least 3/8" (10mm) I.D.
LUBRICATION
Use SIOUX No. 288 air motor oil. An airline lubricator, set to deliver 2 to 4 drops per minute, is recommended. If a lubricator is
not used, add .04 oz. (1.2cc, 12 to 15 drops) of oil into the air inlet twice daily.
Lubricate the gearing every 100 hours of operation with SIOUX No. 289A grease.
GENERAL OPERATION
Motor speed may be controlled by adjusting the slotted head screw in the trigger.
The direction of spindle rotation is controlled by the reversing button. When the button is depressed, the spindle
rotates counterclockwise. Always depress the button fully to obtain full power. The reversing button can be locked in
the reverse direction by fully depressing and rotating the button clockwise.
