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.

•DynabradeAir 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: APreventative 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 20 SCFM (example: if the tool specification states 40 SCFM, set the drip rate on the

filter-lubricator to 2 drops per minute). DynabradeAir 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®).

•ADrop-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 DynabradeAir 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.

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 58368 Bearing and the top of the balancer. Rest the separator on the table of the arbor press

and push the motor shaft balancer out of the 58368 Bearing. Remove 59057 “Top Hat” Seal and 59083 Felt from 59076 Front Bearing Plate.

11. Disassemble the balancer assembly as follows:

a.) Place motor shaft balancer assembly into a soft jaw vise. Using a thin screwdriver, pick out the end of 95630 Snap Ring and remove. 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 arbor press remove 59084 V-Seal.

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: Clean and inspect all parts for defects before assembling.

1. Assemble the balancer assembly as follows:

a.) Install 59084 V-Seal onto the balancer shaft. Install with flexible lip of seal facing hex of balancer shaft. Be certain seal is pressed

completely over shaft step. See Drawing 1.

b.) Install 95360 Snap Ring between flange of 59084 V-Seal and hex of balancer shaft.

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.) Use the 57091 Bearing Press Tool to press 56052 Bearing with seal side toward hex of balancer shaft up to shaft step as shown in Drawing 1.

This is a firm press fit for proper retention of bearing.

2. Place the motor shaft balancer in a soft aluminum or bronze jaw vise with large end pointing up.

3. Apply 1 drop of #271 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 is 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. Place the 59083 Felt into the 59057 “Top Hat” Seal.

5. Install the felt and the “Top Hat” Seal onto the motor shaft balancer so that they are centered as is shown in Drawing 2.

6. Use the small end of the 57091 Bearing Press Tool and the 96232 Arbor Press to install the 58368 Bearing onto the motor shaft balancer as

shown in Drawing 3.

7. Install the 59076 Front Bearing Plate onto the motor shaft balancer, fitting it to the bearing, felt, and “Top Hat” Seal as is shown in Drawing 4.

8. Install the rotor key and the rotor onto the motor shaft balancer.

9. Lubricate the 56073 Vanes with the 95842 DynabradeAir Lube (10W/NR or equivalent) and install them into the rotor.

10. Install the 59051 Cylinder so that the short line-up pin fits into the front bearing plate.

To Assemble (Continued):

11. Install the 58368 Bearing into the 59077 Rear Bearing Plate.

12. Use the small end of the 57091 Bearing Press Tool and the arbor press to install the rear bearing/plate onto the motor shaft balancer as is shown in

Drawing 5. Press the bearing/plate down until it touches the cylinder. This should create a snug fit between the bearing plates and cylinder.

13. Install the 01024 O-Ring into the cylinder and apply a small amount of the DynabradeAir Lube onto the o-ring.

14. Coat the 50659 O-Ring with the DynabradeAir Lube and install it into the 59058 Lock Ring. Slip these over the counter weight of the 3/32' and

the 3/16" orbit sanders.

15. Place a mark on the edge of the motor opening to identify the location of the line-up notch on the inside of the housing.

16. Install the motor assembly into the housing. Be certain that the line-up pin enters the notch in the housing.

17. Use the 57092 Collar to carefully hold the tool in a vise so that the counter balance is pointing up.

18. Use the 56058 Lock Ring Tool to tighten the 59058 Lock Ring by turning it clockwise. (Torque to 23 N•m/200 in.- lbs.)

19. Use the 26 mm open-end wrench to install a weight-mated sanding pad.
