Work Stations
The tool is intended to be operated as a hand held tool. It is always recommended that the tool be used when standing on a solid floor.
It can be in any position but before any such use, the operator must be in a secure position having a firm grip and footing and be aware
that the sander can develop a torque reaction. See the section "Operating Instructions".
Putting the Tool into Service
Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 PSI (6.3 bar) when the tool is running with the
lever fully depressed. It is recommended to use an approved 3/8 in. (10 mm) x 25 ft (8 m) maximum length airline. It is recommended
that the tool be connected to the air supply as shown in Figure 1.
Do not connect the tool to the airline system without incorporating an easy to reach and operate air shut off valve. The air supply
should be lubricated. It is strongly recommended that an air filter, regulator and lubricator (FRL) be used as shown in Figure 1 as this
will supply clean, lubricated air at the correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such
equipment is not used then the tool should be manually lubricated
To manually lubricate the tool, disconnect the airline and put 2 to 3 drops of suitable pneumatic motor lubricating oil such as Fuji Kosan
FK-20, Mobil ALMO 525 or Shell TORCULA® 32 into the hose end (inlet) of the machine. Reconnect tool to the air supply and run tool
slowly for a few seconds to allow air to circulate the oil. If the tool is used frequently, lubricate it on a daily basis or lubricate it if the tool
starts to slow or lose power.
It is recommended that the air pressure at the tool be 90 PSI (6.3 Bar) while the tool is running so the maximum r/min is not exceeded.
The tool can be run at lower pressures but should never be run higher than 90 PSI (6.3 Bar). If run at lower pressure the performance
of the tool is reduced.
Operating Instructions
1. Read all instructions before using this tool. All operators must be fully trained in its use and aware of these safety rules. All
service and repair must be carried out by trained personnel.
2. Make sure the tool is disconnected from the air supply. Select a suitable abrasive and secure it to the back-up pad. Be careful
and center the abrasive on the back-up pad.
3. Always wear required safety equipment when using this tool.
4. When sanding always place the tool on the work then start the tool. Always remove the tool from the work before stopping. This
will prevent gouging of the work due to excess speed of the abrasive.
5. Always remove the air supply to the sander before fitting, adjusting or removing the abrasive or back-up pad.
6. Always adopt a firm footing and/or position and be aware of torque reaction developed by the sander.
7. Use only correct spare parts.
8. Always ensure that the material to be sanded is firmly fixed to prevent its movement.
9. Check hose and fittings regularly for wear. Do not carry the
tool by its hose; always be careful to prevent the tool from
being started when carrying the tool with the air supply
connected.
10. Dust can be highly combustible. Vacuum dust collection
bag should be cleaned or replaced daily. Cleaning or
replacing of bag also assures optimum performance.
11. Do not exceed maximum recommended air pressure. Use
safety equipment as recommended.
12. The tool is not electrically insulated. Do not use where
there is a possibility of coming into contact with live
electricity, gas pipes, water pipes, etc. Check the area of
operation before operation.
13. Take care to avoid entanglement with the moving parts of
the tool with clothing, ties, hair, cleaning rags, etc. If
entangled, it will cause the body to be pulled towards the
work and moving parts of the machine and can be very
dangerous.
14. Keep hands clear of the spinning pad during use.
15. If the tool appears to malfunction, remove from use im-
mediately and arrange for service and repair.
16. Do not allow the tool to free speed without taking precau-
tions to protect any persons or objects from the loss of the abrasive or pad.

The 3”(77mm) Random Orbital Sander service instructions section provided is for use after completion of the warranty period.
Motor Disassembly
1. Lightly secure the tool in a vise using the XPA0026 Service collar or padded jaws. Use a 17mm pad wrench to secure the spindle
and Spin the Pad counter clock-wise off the spindle
2. Remove the lock ring with the XPA0025 Motor lock ring wrench/Spindle Puller Tool. The motor assembly can now be lofted out of
the housing. Remove the o-ring from the lock ring.
3. Secure the motor assembly by clamping the shaft balancer in a padded jaw vise and remove the retaining ring from the end of
the Shaft Balancer and the O-Ring from the cylinder.
4. Remove the rear end plate. This may require supporting the rear endplate with a bearing separator. Use A light press force to
push the shaft balancer through the bearing. Then remove the cylinder, Vanes and the rotor. Remove the key from the shaft
balancer. Support the front endplate with a bearing separator and use a light press force to push the shaft balancer through the
bearing it may be necessary to remove the bearing with a bearing separator if it came out of the front endplate and stuck to the
shaft of the shaft balancer.
5. Remove the bearing from the endplates by using the XPA0036 bearing removal tool to press out the bearings.
Shaft Balancer and Spindle Disassembly:
1. Grip the shaft end of the shaft balancer in a padded vise. With a thin screwdriver pick out the slotted end of the Retaining Ring
and peel out
2. Screw the threaded end of the 5/16-24 to 1/4-20 Adapter into the male end of the service wrench. Screw the service wrench
assembly into the spindle assembly until hand tight. apply a gentle heat from a propane torch or hot air gun to the large end of
the shaft balancer until it is about 100℃(212℉) to soften the adhesive. Do not over heat. Remove the spindle assembly by
using the slider to give sharp outward blows to the spindle. Allow the parts to cool so they are safe to handle. Follow one of the
appropriate directions below.
3. Remove the retaining ring from the spindle assembly. Use a small bearing separator to remove the bearing, shim, bearing, shim
and the washer from the spindle assembly.

ASSEMBLY INSTRUCTIONS
NOTE: All assembly must be done with clean dry parts and all bearings are to be pressed in place by the correct tools and procedures
as outlined by the bearing manufacturers.
Housing Assembly:
1. Install Throttle Lever into Housing with the Spring Pin.
2. Lightly grease the O-ring and place it on the Speed Control. Install Valve Stem. O-ring (cleaned and lightly greased) and insert
the Speed control into the Housing in the midway position. Install the Retaining Ring.
CAUTION: Make sure the Retaining Ring is completely snapped into groove in the Housing.
3. Install the Valve Seat, the Valve and the Valve Spring. Coat the threads of the Bushing Assembly with 1 or 2 drops of Luctite®
222 or equivalent non-permanent pipe thread sealant. Screw the assembly into the Housing. Torque to 60 in/lbs (6.77 Nm.)
Spindle Beaing, and Shaft Balancer Assembly:
1. Place the T-5A Spindle Bearing Pressing Tool Base onto a flat, clean surface of a small hand press or equivalent with the spindle
pocket facing upward. Place the Spindle into the spindle pocket with the shaft facing upwards. See Figures 1 and 2
2. Place the Washer on the Spindle shaft with the curve of the Washer facing out so that the outside diameter of the Washer will
contact the outer diameter of the Bearing (one seal). Lay the Shim on the shoulder of the Spindle. Place the Bearing (one seal)
on the Spindle with the seal side toward the Washer.
NOTE: Make sure that both the inner and outer races of the Bearings are supported by the Bearing Press Tool when pressing
them into place. Press the Bearing onto the shoulder of Spindle using the T-5B Spindle Bearing Pressing Tool Top as shown in
Figure 2.
3. Place the Shim over the Spindle shaft and onto the face of the Bearing making sure it is on center. Press the (no seals/shields)
Bearing down using the T-5A Spindle Bearing Pressing Tool Top, being careful to make sure the Shim is still centered on the
vertical axis of the Spindle shaft and Bearing. See Figure 3.
NOTE: When the Spindle Assembly is done correctly, the Bearings will rotate freely but not loosely and the Shim can be moved
but will not slide or move by gravity.
4. Secure the Retaining Ring onto the Spindle Assembly making sure it is completely snapped into the groove. Set the Spindle
Assembly aside.
5. Take the Filter and center it on the small bore that the original filter was in before removal. With a small diameter screwdriver or
that end rod, press the filter into the bore until it is flat in the bottom of the bore. Place the valve into the bore so it oriented
correctly, then press the retainer into the bore until it is flush with the bottom of the bearing bore
6. Apply a pin head size drop of #271 Loctite® or equivalent to the outside diameter of each of the bearings on the Spindle
Assembly. Spread the drop of bearing locker around both bearings until distributed evenly.
CAUTION: Only a very small amount of bearing locker is needed to prevent rotation of the bearing OD. Any excess will make
future removal difficult. Place the spindle assembly into the bore of the Shaft Balancer and secure with the Retaining Ring.
CAUTION: Make sure that the Retaining Ring is completely snapped into the groove in the Shaft Balancer. Allow the adhesive to
cure.

Motor Assembly:
1. Use the larger end of the T-13 Bearing Press Sleeve to Press the front Bearing (with 2 Shields) onto the shaft of the Shaft
Balancer.
2. Slide the Front Endplate with the bearing pocket fac-ing down onto the Motor Shaft. Gently press the Front Endplate onto the
front Bearing using the larger end of the T-13 Bearing Press Sleeve until the front Bearing is seated in the bearing pocket of the
Front Endplate.
CAUTION: Only press just enough to seat the bearing into the pocket. Over-pressing can damage the bearing.
3. Place the Key into the groove on the Shaft Balancer. Place the Rotor onto the shaft of the Shaft Balancer, making sure that it is a
tight slip fit.
4. Oil the five vanes with a quality pneumatic tool oil and place in the slots in the Rotor. Place the Cylinder Assembly over the Rotor
with the shorter end of the Spring Pin engaging the blind hole in the Front Endplate.
NOTE: The Spring Pin must project .060 in. (1.5 mm) above the flanged side of the cylinder
5. Press fit the rear(2) bearing (2 shields) into the rear Endplate with the T-1B Bearing Press Tool. Make sure the T 1B Press Tool is
centered on the O.D. of the outer race. Lightly press fit the rear endplate and bearing assembly over the Shaft Balancer using
the small end of the T-13 Bearing Press Sleeve. The sleeve should press only the inner race of the bearing.
IMPORTANT: The Rear End-plate and Bearing Assembly is pressed correctly when the Cylinder is squeezed just enough
between the Endplates to stop it from moving freely under its own weight when the shaft is held horizontal, but be able to slide
between the Endplates with a very light force. If pressed to tightly the motor will not run freely. If the pressed assembly is to loose,
the motor will not turn freely after assembly in the Housing.
6. Secure the assembly by placing the Retaining Ring in the groove of the Shaft Balancer.
CAUTION: The Retaining Ring must be placed so that the middle and two ends of the hoop touch the bearing first. Both raised
center portions must be securely “snapped” into the groove in the Shaft Balancer by pushing on the curved portions with a small
screwdriver.
7. Carefully screw the Lock Ring into the Housing using the T-6 Motor Lock Ring Wrench. Torque to 60 in/lbs (6.77mm).
NOTE: A simple technique to assure first thread engagement is to turn the lock ring counter clockwise with the service tool while
applying light pressure. You will hear and feel a click when the lead thread of the lock ring drops into the lead thread of the
housing, then turn clockwise to tighten.
8. Spin on a new Pad and hand tighten it using a 17 mm Pad Wrench.
Testing:
Place 3 drops of quality pneumatic air tool oil directly into the motor inlet and connect to a 90 psig (6.2 bar) air sup-ply. The tool should
run between 9,500 RPM and 10,500 for 10,000 RPM machines or 11,500 and 12,500 RPM for 12,000 RPM machines when the air
pressure is 90 psig (6.2 bar) at the inlet of the tool while the tool is running at free speed. This free speed will be about 500 RPM to
1,000 RPM less when a Vacuum or Hook Face Pad is used because of wind resistance. This will not affect performance when
sanding.* Loctite® is a registered trademark of the Loctite Corp.
