counterclockwise

 to tighten them. Tighten the joint 

between 20 and 25 ft.-lb. (27.1 and 33.9 Nm) torque.

15. Using finger pressure, press the Seal Cup Assembly (55), 

felt end trailing, onto the rotor end of the Collet Body (58). 
Press the Cup Assembly to the shoulder of the Collet 
Body. Saturate the felt with 

Ingersoll Rand

 No. 50 Oil.

16. Insert a 5/32" pin through the opening in the Extension 

Housing and the cross hole in the Spindle to keep the 
Spindle from rotating. Thread the Collet Body and Seal 
Cup Assembly onto the Spindle and tighten it between 14 
and 19 ft.-lb. (19 and 26 Nm) torque. Install the Extension 
Housing Plug (52).

17. Slide the Spindle Bearing Shield (56), large opening first, 

over the Collet Body and into the Extension Housing. 

Using snap ring pliers, install the Shield Retainer (57) in 
the internal groove in the Extension Housing.

18. Slide the Handle Clamp (61) with the assembled handle 

onto the Extension Housing and position the handle in 
the most comfortable position. Tighten the Mounting 
Screw Nut (64) between 10 and 12 ft.-lb. (13.5 and 16.3 
Nm) torque.

19. Insert the Collet (59) into the Collet Body and thread the 

Collet Nut (60) onto the Collet Body.

20. Use the Collet Body Wrench (82) on the flats of the Collet 

Body and the Collet Nut Wrench (81) on the Collet Nut to

Troubleshooting Guide

Trouble

Probable Cause

Solution

Low power or low free 
speed

Insufficient air pressure

Check air line pressure at the Inlet of the Tool. It must be 90 
psig (6.2 bar/620 kPa).

Clogged muffler elements

Disassemble the Tool and agitate bare Motor Housing and 
Flange in clean kerosene. Back flush muffler elements by 
blowing into the exhaust ports with an air gun until all 
contaminants and obstructions are removed. If elements 
cannot be cleaned, replace the Motor Housing and/or the 
Flange.

Plugged Inlet Screen (2)

Clean the Inlet Screen with a stream of air or replace the 
Screen.

Worn or broken Vanes (17)

Install a 

complete

 set of new Vanes.

Loose Extension Housing (51) or Gear 
Case Adapter (32)

Tighten the Housing or Adapter to 20 to 25 ft.-lb. (27 to 34 Nm) 
torque.

Worn or broken Motor Housing (9)

Replace the Motor Housing.

Internal air leakage in the Motor 
Housing indicated by high air 
consumption/low speed.

Replace the Motor Housing.

Grit buildup under the Throttle Lever 
(10) restricting full Throttle Valve 
Plunger (12) movement.

Remove the Throttle Lever and clean the groove in the Motor 
Housing.

Bent stem on Throttle Valve (6)

Replace the Throttle Valve.

Front Seal Cup Assembly (20) dragging 
against the shield of the Front Rotor 
Bearing (21)

Reposition the Front Seal Cup Assembly.

Rough operation / 
vibration

Improper lubrication or dirt buildup

Inject 3 cc of clean kerosene into the Inlet, operate the Tool for 
30 seconds and 

immediately

 inject 3 cc of the recommended 

oil into the Inlet and run the Sander long enough to coat the 
internal parts with the oil.

Worn or broken Rear Rotor Bearing 
(13) or Front Rotor Bearing

Replace the worn or broken Bearings. Examine the Front End 
Plate (18), Front End Plate Spacer (19), Front Seal Cup 
Assembly (20) and Rear Rotor Bearing Spacers (14) and 
replace any damaged parts. If the attached rotor plate is 
damaged, replace the Rotor (16).

Worn or broken Rear Spindle Bearing 
(49) or Front Spindle Bearing (53)

Replace the Bearings.

Dirt contaminated Front Spindle 
Bearing

Replace the Bearing.

Worn, bent or broken Spindle (44)

Replace the Spindle if, when mounted between centers, the 
runout on the spindle body exceeds 0.002" T.I.R. or 0.0005" 
T.I.R. on the bearing mounting diameters.

Excessive runout

Loose Collet Nut (60)

Tighten the Collet Nut until snug.

Worn or damaged Collet (59), Collet 
Nut or Collet Body (58)

Replace the damaged component and retest.

Bent, worn or broken Spindle

Replace the Spindle if, when mounted between centers, the 
runout on the spindle body exceeds 0.002" T.I.R. or 0.0005" 
T.I.R. on the bearing mounting diameters.

Worn or damaged Front Spindle 
Bearing

Replace the Front Spindle Bearing.
