INSTRUCTIONS FOR
NO. 2 1/2 SERIES TOOLS
BE SURE TO LUBRICATE
All Sioux Air Tools are manufactured to extremely close tolerances. Reasonable care and preventative maintenance will greatly prolong
their service life.
This line of tools is designed for a long life of continuous duty on assembly lines, with a minimum of service and maintenance. Rotating
parts are mounted on extra-capacity ball bearings, rotors and spindles are finished to extreme accuracy for power and low air con-
sumption, gears and pinions are oversize and correctly hardened for quietness and long life.
Special attention has been given to ease of servicing. These tools can be disassembled and reassembled with ease.
Before connecting the tool, blow the air line to remove water and dirt which may have accumulated. This is especially important for a
new line or when the line has not been used for some time.
GEARS
The gears are lubricated at the factory. Every 100 hours of operation add 1/4 oz. of Sioux Grease No. 289A.
AIR MOTORS
Sioux Air line lubricators are recommended. When used, adjust lubricator to deliver 2 to 4 drops of Sioux Air Motor Oil No. 288 per
minute to the air tool. If tool is not used with a lubricator, place 10 to 15 drops of Sioux No. 288 oil into air inlet twice daily.
SCREW DRIVER AND NUT RUNNER CLUTCHES
Lubricate every 40 hours using No. 1232A Sioux Grease on the clutch jaws and bearing surfaces.
OPERATION
The air motor is started by depressing the operating lever or trigger. Motor speed may be controlled by adjusting the slotted head
control which is located on the tool housing or, on some models, on the trigger surface.
If the tool is equipped with reversing button, always depress the button fully to obtain maximum power.
Air supply hose should not be less than 3/8" I.D. If extension hose is necessary, use 1/2" I.D. hose, with couplings not less than 3/8 I.D.
SAFETY PRECAUTIONS
1. Keep Work Area Clean: Cluttered areas and benches invite accidents.
2. Wear Proper Apparel: No loose clothing or jewelry to get caught in moving parts.
3. Use Safety Glasses: Protect your eyes.

Clutch Selection Information
Screw Drivers And Nut Runners
HOW TO SELECT PROPER CLUTCH
STALL DRIVE—Spindle turns with motor Motor stalls when fastener is tight. For soft pull up, machine,
wood or self tapping screws.
DIRECT CLUTCH—Spindle doesn’t turn with motor. Pressure on spindle engages straight jaws to
turn spindle. Motor stalls when fastener is tight. Excellent stall type tool when tightening group of
fasteners without turning off motor.
POSITIVE CLUTCH-ANGULAR JAW—Spindle doesn’t turn with motor. Pressure on spindle
engages angular jaws to turn spindle. Clutch ratchets when certain tightness is reached. Tightness
determined from pressure by operator For wood screws, sheet metal screws, lag screws, machine
screws.
POSITIVE CLUTCH—Similar to angular jaw except 4 rollers engage angular teeth. Ratchets faster
and blow not as hard. Life increased on light applications.
ADJUSTABLE CLUTCH-Spindle doesn’t turn with motor. Pressure on spindle causes spindle to
turn. When fastener is tight clutch will ratchet. Adjusting spring pressure will change torque. For
consistent torque control, little operator reaction.
Above 25 Inch Pounds
To adjust clutch place adjusting wrench (No. 53099) with pin through
opening in the clutch case. Place 1/4" HEX (Allen type) wrench in the Bit
Holder, press in and turn until adjusting wrench falls into the slot of the Nut
of the Clutch. Keep Bit Holder depressed in with HEX Wrench and turn
clockwise to increase and counterclockwise to decrease Torque.
Below 25 Inch Pounds Change to Green Spring No. 41284
Again place adjusting wrench in position as for the higher Torque, but place
a screw driver blade through the bit holder opening until in contact with the
slot at the far end. Rotate screw driver until adjusting wrench falls into place,
again rotate screw driver clockwise to increase and counter-clockwise to
decrease Torque.
