INSTRUCTIONS & PARTS LIST FOR NO. 2S SERIES SCREWDRIVERS & DRILLS
Read and understand these instructions before operating this tool.
Everyone using, maintaining, changing accessories or working near this tool must read, understand and follow these Safety Instructions!
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
Depress the trigger to start the tool. Motor speed may be controlled by adjusting the slotted head screw on the top rear of the tool.
On reversing tools, the direction of spindle rotation is controlled by the reversing lever on the bottom front of the tool.

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
