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.

2. Use the larger end of the XPA0494 Bearing Press Sleeve to press the front Bearing (with 2 Shields) onto the shaft of the Shaft
Balancer.
3. Slide the Front Endplate with the bearing pocket facing down onto the Motor Shaft. Gently press the Front End Plate onto the
Bearing using the larger end of the XPA0494 Bearing Press Sleeve until the Front Bearing is seated in the bearing pocket of the
Endplate.
CAUTION: Only press just enough to seat the bearing into the pocket. Over-pressing can damage the bearing.
4. Place the Key into the groove on the Shaft Balancer. Place the Rotor on the Shaft Balancer, making sure that it is a tight slip fit.
5. Oil the five Vanes with a quality pneumatic tool oil and place them in the slots of the Rotor. Place the Cylinder Assembly over the
Rotor with the short end of the Spring Pin engaging the blind hole in the Front Endplate.
NOTE: The Spring Pin must project 0.6”(1.5mm) above the flanged side of the Cylinder.
6. Press fit the rear Bearing (2 shields) into the Rear Endplate with the XPA0195 Bearing Press Tool. Make sure the XPA0195
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 XPA0494 Bearing Press Sleeve. The sleeve should press only the inner race of the bearing.
IMPORTANT: The Rear Endplate 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 the assembly is 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. 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. Lightly grease the O-Ring and place in the air inlet of the Cylinder Assembly.
8. Lightly grease or oil the inside diameter of the Housing, line up the Spring Pin with the marking on the Housing and slide the
Motor Assembly into the Housing. Make sure the Spring Pin engages the pocket in Housing.
9. Carefully screw the Lock Ring into the Housing with the XPA0025 Motor Lock Ring Wrench/Spindle Puller Tool. Torque to 60
in/lbs (6.77 Nm.)
NOTE:A simple technique to assure first thread engagement is to turn the lock ring counter clockwise with the XPA0025
Motor Lock Ring Wrench/ Spindle Puller 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.
10. Spin on a new Pad and hand tighten it using a 24 mm Pad Wrench.
Testing:
Place 3 drops of quality pneumatic air tool oil directly
into the motor inlet and connect it to a 90 PSI (6.3 bar)
air supply. A 12,000 r/min tool should run between
11,500 to 12,500 r/min when the air pressure is 90 PSI
(6.3 bar) at the inlet of the tool while the tool is running
at free speed. This free speed will be about 500 r/min to
1,000 r/min less when a Vacuum or Hook Face Pad is
used because of wind resistance. This will not affect
performance when sanding.

Vibration/Rough Operation
For vacuum machines it is possible to
have too much vacuum while sanding on
a flat surface causing the pad to stick to
the sanding surface.
For LSG machines add extra washer(s)
to the pad spindle to increase the gap
between the pad and shroud. For LSC
machines reduce vacuum through
the vacuum system and/or add extra
washer(s) to the pad.
