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.

•

It is strongly recommended that all Dynabrade rotary vane air tools be used with a Filter-Regulator-Lubricator to minimize the possibility of misuse due to unclean air, wet air or insufficient lubrication. Dynabrade recommends the following: 11405 Air Filter-Regulator-Lubricator (FRL) – Provides accurate air pressure regulation and two stage filtration of water contaminates. 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). 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.

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 Dynabrade Air 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. Check the fit between the bearing plates and cylinder. Grasp the outer diameter of

the bearing plates, one in each hand. Twist the plates back and forth, if they move, carefully tighten the fit until you cannot move the plates.

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

14. Coat the 50659 O-Ring with the Dynabrade Air 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 17 N•m/150 in.- lbs.)

19. Use the 26mm open-end wrench to install a 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 94590 Pin from housing, lever and comfort platform.

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.

6. Apply a small amount of #567 Loctite

(or equivalent) around the threads of the first inlet bushing and tighten into housing to 23 N•m/200 in.-lbs.

7. Install lever and comfort platform on housing with 94590 Pin centered on housing.

Note: Motor should operate at between 11,000 and 12,000 RPM at 6.2 bar (90 PSIG). RPM should be checked with a tachometer. Before operating,

we recommend that 2-3 drops of Dynabrade Air Lube P/N 95842 (or equivalent) be placed directly into the air inlet with throttle lever depressed. Operate the machine for approximately 30 seconds before application to workpiece to determine if machine is working properly and safely and to allow lubricating oils to properly dispense through machine.
