				Therefore, the adjustment, although simple, should only be
				attempted by a competent technician using the proper
				equipment.

Always wear eye protection when operating or performing maintenance on this tool.

Always turn off the air supply and disconnect the air supply hose before installing, removing or adjusting any accessory on this tool, or before performing any maintenance on this tool.

LUBRICATION

Each time a Series QS Screwdriver is disassembled for maintenance and repair or replacement of parts, lubricate the tool as follows:

1.Coat all exposed gears with Ingersoll-Rand No. 67 Grease and work some of the Grease into the gearing of the Spindle Assembly (42).

2.Work approximately 6 to 8 cc of Ingersoll-Rand No. 28 Grease into the ball pockets, jaws, adjusting nut lock and shaft threads of the clutch mechanism.

3.Use Ingersoll-Rand No. 10 Oil to lubricate the motor. Inject approximately 1 to 2 cc of oil into the air inlet before attaching the air hose to the tool.

SPEED ADJUSTMENT

In addition to adjustable clutches for controlling torque, Series QS Lever Inline Screwdrivers are furnished with the ability to precisely control speed, within certain ranges. Setting the speed requires a tachometer.

The Back Cap (6) has a small, molded stud on the end face of the Cap nearest the Exhaust Diffuser (15). That stud controls the radial location of the Diffuser which controls the opening size of the exhaust ports. Take an initial reading of the tool speed by applying a tachometer with a convex tip to the inside of the Bit Holder (84). Using the procedure required to activate the motor of your particular model tool, bring the motor to maximum free speed.

After determining the actual velocity, shut off the air supply and disconnect the air line. Use a 3/4” wrench to loosen the Inlet Bushing. The longest slot in the Exhaust Diffuser will contain the molded stud on the Back Cap. Rotate the Diffuser to open the exhaust ports to increase speed or rotate it to restrict the exhaust to reduce speed. Being careful not to allow the Diffuser to damage the molded stud, tighten the Inlet Bushing to 15 ft-lbs. (20 Nm) torque. Connect the air line and restore the air supply and check the velocity again. Determine which direction you need to rotate the Diffuser to obtain the desired speed and then rotate it accordingly. Best results are achieved by using gradual increments and frequent tachometer readings. Be sure to turn off the air supply and disconnect the line when making adjustments.
