OPERATING INSTRUCTIONS (continued)
• Keep hand and clothing away from working end of the air tool.
Operation: Be sure that any loose clothing, hair and all jewelry is properly restrained.
• Secure inlet bushing on air tool with a wrench before attempting to install the air fitting to avoid damaging housing assembly.
• Check tool RPM (speed) with tachometer with air pressure set at 90 PSIG while the tool is running. If tool is operating at a higher speed than the RPM marked on the tool
housing, or operating improperly, the tool must be serviced and corrected before use.
Caution: Tool RPM must never exceed abrasive/accessory RPM rating. Check accessory manufacturer for details on maximum operating speed or special
mounting instructions.
• With power source disconnected from air tool, mount recommended accessory into collet assembly.
• Connect air tool to power source. Be careful NOT to depress throttle lever in the process. Do not expose air tool to inlet pressure above 90 PSIG or (6.2 Bars).
Caution: After installing the accessory, before testing or use and/or after assembling tool, the Dynorbital-Spirit™ must be started at a reduced speed to check for good
balance. Gradually increase tool speed. DO NOT USE if tool vibration is excessive. Correct cause, and retest to insure safe operation.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris.
• Use a vise or clamping device to hold work piece firmly in place.
• Do not apply excessive force on tool or apply “rough” treatment to it.
• Always work with a firm footing, posture and proper lighting.
Report to your supervisor any condition of the tool, accessories, or operation you consider unsafe.

LUBRICATOR SETTING
•Ideally the air supply should be free from moisture.
Incorporating a refrigerated air dryer after the
compressor and drain valves at each tool station
(as shown) further reduces moisture from
condensation in the air supply.
•Dynabrade Air Power Tools are designed to
operate at 90 PSIG (6.2 Bar/620 kPa) maximum
air pressure at the tool inlet, when the tool is
running. Use recommended regulator to control
air pressure.

Maintenance Instructions
Important: A Preventative Maintenance Program is recommended whenever portable power tools are used.
•Use only genuine Dynabrade replacement parts to insure quality. To order replacement parts, specify Model#, Serial# and RPM of your air tool.
•All Dynabrade Rotary Vane air tools must be used with a Filter-Regulator-Lubricator to maintain all warranties. Dynabrade recommends the following:
11405 Air Filter-Regulator-Lubricator (FRL) – Provides accurate air pressure regulation and two stage filtration of water contaminants. Operates 40
SCFM/1,133 LPM @ 100 PSIG with 3/8" NPT female ports.
•Dynabrade recommends one drop of air lube per minute for each 10 SCFM (example: if the tool specification states 40 SCFM, set the drip rate on the
filter-lubricator to 4 drops per minute). Dynabrade Air Lube (P/N 95842: 1 pt 473 ml) is recommended.
Routine Preventative Maintenance: Check free speed of Dynorbital-Spirit™ using a tachometer.
•Mineral spirits are recommended when cleaning the tool and parts. Do not clean tool or parts with any solvents or oils containing acids, esters,
ketones, chlorinated hydrocarbons or nitro carbons.
•DO NOT clean or maintain tools with chemicals that have a low flash point (example: WD-40®).
•A Drop-In Motor and Tune-Up Kit are available, see specific kit number on page 9.
•Air tool stampings must be kept legible at all times, if not, reorder and replace. User is responsible for maintaining specification information i.e.:
Model #, S/N, and RPM.
•Blow air supply hose out prior to initial use.
•Visually inspect air hoses and fittings for frays, visible damage and signs of deterioration. Replace damaged or worn components.
•Refer to Dynabrade's Warning/Safety Operating Instructions Tag (Reorder No. 95903) for safety information.
After maintenance is performed on tool, add a few drops of Dynabrade Air Lube (P/N 95842) to the air line and start the tool a few times to lubricate air motor.
Check for excessive tool vibration.
Handling and Storage:
•Protect tool inlet from debris (See Notice Below).
•DO NOT carry tool by air hose.
•Protect abrasive accessories from exposure to water, solvents, high humidity, freezing temperature and extreme temperature changes.
•Store accessories in protective racks or compartments to prevent damage.
Notice
All Dynabrade motors use the highest quality parts and materials available and are machined to exacting tolerances. The failure of quality pneumatic motors
can most often be traced to an unclean air supply or the lack of lubrication. Air pressure easily forces dirt or water contained in the air supply into motor
bearings causing early failure. It often scores the cylinder walls and the rotor blades resulting in limited efficiency and power. Our warranty obligation is
contingent upon proper use of our tools and cannot apply to equipment which has been subjected to misuse such as unclean air, wet air or a lack of
lubrication during the use of this tool.
One Year Warranty
Following the reasonable assumption that any inherent defect which might
prevail in a product will become apparent to the user within one year from
the date of purchase, all equipment of our manufacture is warranted
against defects in workmanship and materials under normal use and
service. We shall repair or replace at our factory, any equipment or part
thereof which shall, within one year after delivery to the original purchaser,
indicate upon our examination to have been defective. Our obligation is
contingent upon proper use of Dynabrade tools in accordance with factory
recommendations, instructions and safety practices. It shall not apply to
equipment which has been subject to misuse, negligence, accident or
tampering in any way so as to affect its normal performance. Normally
wearable parts such as bearings, contact wheels, rotor blades, etc., are not
covered under this warranty.

Motor Assembly/Disassembly Instructions - Dynorbital -Spirit™
Important: Manufacturers warranty is void if tool is disassembled before warranty expires.
A Full Service Repair Kit P/N 57098, is available which includes special repair tools for correct disassembly/assembly of the sander.
To Disassemble
1. Disconnect sander from air supply.
2. Invert the sander, and place the 57092 Repair Collar (supplied in the 57098 Full Service Repair Kit) around the housing and secure in a vise. Padding
can be used on the vise jaws to protect the housing. Important: Do not over tighten the sander in the vise. If the sander is held too tight the
removal of the lock ring and air motor will be difficult.
3. Remove sanding pad with the 50679 26 mm Open-end Wrench (supplied with the sander).
4. Insert 56058 Lock Ring Tool (supplied in 57098 Full Service Repair Kit) into the corresponding tabs of lock ring. Loosen the 59058 Lock Ring
turning it counterclockwise.
5. Remove the 59058 Lock Ring and the 50659 O-Ring from the air motor assembly (3/32" and 3/16" dia. orbits only).
6. Remove 01024 O-Ring and 98463 Retaining Ring from motor assembly.
7. Fasten a 2 in. bearing separator (P/N 96346 available) around the 59051 Cylinder just below the 59077 Rear Bearing Plate. Place the air motor
assembly in a #2 arbor press (P/N 96232 available) so that the separator is resting on the table of the arbor press and with the balancer pointing down.
8. Use a flat nose 3/16" dia. drive punch as a press tool. Place it against the small end of the motor shaft balancer and push the shaft out of the
upper 58368 Bearing.
9. Remove the rotor, vanes and rotor key from the motor shaft balancer.
10. Again fasten the 2 in. bearing separator between remaining 59076 Front Bearing Plate/58368 Bearing and the top of the balancer. Rest the separator
on the table of the arbor press and push the motor shaft out of the 58368 Bearing.
11. Disassemble the balancer assembly as follows:
a.) Place motor shaft assembly into a soft jaw vise. Using a thin screwdriver, pick out the end of 95630 Snap Ring and peel out. This will loosen the
balancer assembly.
b.) Screw the threaded portion of the 56056 Bearing Puller (supplied in 57098 Repair Kit) into the 57069 Balancer Shaft and heat the outside of the
motor shaft balancer to approximately 200° F (approximately 10 seconds with a propane torch). Now, using the slider weight, pull
the assembly out.
c.) Press off 56052 Bearing with a bearing separator and remove bearing seal and bearing shield.
12. If during step 11, the 56052 Bearing remains in the motor shaft balancer, it can be removed by the heating the shaft balancer again and using either an
inside bearing puller or a blind hole bearing puller.
To Assemble:
Important: Be certain parts are clean and in good repair before assembling.
1. Assemble the balancer assembly as follows:
a.) Install 95630 Snap Ring onto balancer shaft. Install 95628 Shield with convex face toward hex of balancer shaft.
b.) Install 56053 Seal. Note: Be certain seal is pressed completely over shaft step.
c.) Apply 1 drop of #271 Loctite®(or equivalent) and spread over several places around inside diameter of 56052 Bearing and the outside diameter
of the 57069 Balancer Shaft.
d.) Press fit 56052 Bearing with seal side toward hex of balancer shaft up to shaft step as shown in Drawing 1. This must be a firm press fit for
proper retention of bearing.
2. Place the motor shaft balancer in a soft jaw vise with large end-up.
3. Apply 1 drop of #609 Loctite®(or equivalent) and spread over several places around the outside diameter of the 56052 Bearing and slide balancer
assembly into the motor shaft balancer until 56052 Bearing are firmly seated at bottom. Squeeze 95630 Snap Ring into groove in motor shaft balancer
to complete the assembly. Remove from vise. Place 50659 O-Ring and 59058 Lock Ring onto the motor shaft balancer (3/8" orbit models only).
4. Apply 1 drop of #609 Loctite®(or equivalent) and spread around lower area of motor balancer shaft where the front 58568 Bearing will be located.
5. Install 58368 Bearing onto the motor shaft balancer down to the shoulder as shown in Drawing 2.
6. Press 59076 Front Bearing Plate onto 58368 Bearing as shown in Drawing 3 and check for smooth rotation.
7. Install the 98451 Rotor Key and 57090 Rotor on the motor shaft balancer. Place the 56073 Vanes into the rotor slots.
Note: Vanes should be lubricated with Dynabrade Air Lube P/N 95842 (or equivalent) before installation.
8. Place 59051 Cylinder Assembly over rotor. The “short” line-up post goes toward the front bearing plate.
9. Place 58368 Bearing into 59077 Rear Bearing Plate. Apply 1 drop of #609 Loctite®(or equivalent) and spread around inside diameter of 58368 Bearing.

shown in Drawing 4.
11. Install 98463 Snap Ring in groove.
12. Place 01024 O-Ring into recess in side wall of cylinder.
13. Install 50659 O-Ring into 59058 Lock Ring. Slide the lock ring assembly over the motor shaft balancer (3/32" and 3/16" orbits only). Apply 1 drop of
pneumatic tool oil and spread between the motor bearing plate and 50659 O-Ring.
14. Place 1 drop of pneumatic tool oil on 01024 O-Ring.
15. Secure motor housing in vise, using 57092 Collar or padded jaws. Slide motor assembly into second housing. Note: Be certain line-up post enters the
notch in the bottom of the housing and 01024 O-Ring stays seated in cylinder.
16. Tighten lock ring with 56058 Lock Ring Tool to 23 N•m/200 in.-lbs. Attach weight-mated sanding pad.
Valve and Speed Regulator Assemblies:
1. Secure housing in vice using 57092 Collar or padded jaws.
2. Remove inlet bushing, 01468 Spring, 58365 Tip Valve and 01464 Seal from housing. Remove 98927 Pin from housing and lever.
3. Remove 95697 Snap Ring. Press the speed regulator and valve stem out of the housing. Remove the 01025 O-Rings (2) and 98459 O-Ring.
4. Place new 01025 O-Rings (2) on the speed regulator and a new 98459 O-Ring on the valve stem. Then place in housing with valve stem. Install new
95967 Snap Ring. Apply a small amount of pneumatic tool oil to valve o-rings.
5. Place new 01464 Seal in housing. Using tweezers or needle nose pliers, place the tip valve into housing so that the tip valve goes under the valve
stem. Place new 01468 Spring into housing so small end is towards tip valve.
