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, pressure regulator, and
lubricator will insure maximum output and service life of tools.
HOSE AND HOSE CONNECTIONS
Supply hose should be not less than 3/8" (10mm) I.D. Extension hoses should be at least 3/8" (10mm) I.D. Use couplings and fittings with at least 1/4"
(6.4mm) I.D.
LUBRICATION
An airline lubricator, set to deliver one drop per minute, is recommended. If a lubricator is not used, add .04 oz. (1.2cc, 12 to 15 drops) of SIOUX No.
288 air motor oil into the air inlet daily.
Lubricate the gearing every 150 hours of operation with SIOUX No. 1232A grease. Lubricate positive and adjustable clutches every 25 to 50 hours with
SIOUX No. 1232A grease.
GENERAL OPERATION
"1SM" LEVER OPERATED TOOLS
These tools are started by depressing the lever. The output spindle of the tool will not turn until the clutch is engaged by applying pressure to the
fastener after the air motor has started.
"1OM" TRIGGER OPERATED TOOLS
These tools are started by depressing the trigger. The output spindle of the tool will not turn until the clutch is engaged by applying pressure to the
fastener after the air motor has started.
Both lever operated and trigger operated reversing tools have a button to depress to reverse the air motor. 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.
ADJUSTABLE CLUTCH OPERATION
Adjustable clutch tools will continue to ratchet when the preset torque is reached and can only be stopped by removing the tool from the fastener.
Adjustable clutches are adjusted externally with the use of Sioux No. 2366 clutch adjustment wrench or a #1 (3/16", 4.8mm Dia. shank) Phillips
screwdriver. Clutch adjustment is accomplished by rotating the clutch cover until the slot in the clutch case appears. Turn the output spindle of the
tool with a 1/4 (6.4mm) hex key wrench until the groove in the adjusting washer is aligned with the slot in the clutch case. Insert the clutch adjustment
wrench into the groove and push to fully engage the teeth. Turn the clutch adjustment wrench counterclockwise to increase the torque.
Three clutch springs are available and are color coded for torque range.
