INSTRUCTIONS FOR SD9APB SERIES SCREWDRIVERS
SERIAL “B”
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,
pressure 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 3/8" (10mm) I.D. Extension hoses should be at least 1/2" (13mm) 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.
Lubricate positive and adjustable clutches every 40 hours with SIOUX No. 1232A grease.
GENERAL OPERATION
The air motor is started by depressing the operating lever or trigger.
On reversing tools, 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 revers-
ing button on some models can be locked in the reverse direction by fully depressing and rotating the button
clockwise.
Clutch Operation Information
Screw Drivers And Nut Runners
STALL DRIVE ........................................... Spindle turns with motor. Motor stalls when fastener is tight.
DIRECT CLUTCH ...................................... Spindle doesn’t turn with motor. Pressure on spindle engages straight jaws to turn
spindle. Motor stalls when fastener is tight.
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. Torque on the fastener is
determined by how hard the operator pushes on the tool.
POSITIVE CLUTCH ROLLER JAWS ........ Similar to angular jaw except 4 rollers engage angular teeth. Ratchets faster and blow
not as hard.
ADJUSTABLE CLUTCH ............................ Spindle doesn’t turn with motor. Pressure on spindle engages the clutch, causing the
spindle to turn. When fastener reaches a preset torque, clutch will ratchet. Adjusting
spring pressure will change torque.
Adjustment of Adjustable Clutch
ABOVE 25 INCH POUNDS
To adjust clutch place adjusting wrench (No. 53099) with pin
through opening in the clutch case. Place 1/4" (6.4 mm) HEX
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 counterclockwise to decrease
Torque.
