IMPORTANT OPERATING,
MAINTENANCE AND SAFETY
INSTRUCTIONS:
Carefully read all instructions before operating or servicing any
Dynabrade
®
Abrasive Power Tool.
WARNING: Hand, wrist and arm injury may result from repetitive work
motion and overexposure to vibration.
IMPORTANT: All Dynabrade Rotary Vane air tools must be used with a
Filter-Regulator-Lubricator to maintain all warranties.
OPERATING INSTRUCTIONS:
WARNING: Eye, face, respiratory, sound and body protection must be worn
while operating power tools. Failure to do so may result in serious
injury or death. Follow safety procedures posted in workplace.
1. With power source disconnected from tool, securely fasten
abrasive/accessory on tool.
2. Install air fitting into inlet bushing of tool. IMPORTANT: Secure inlet bush-
ing of tool with a wrench before attempting to install the air fitting
to avoid damaging valve body housing.
3. Connect power source to tool. Be careful not to depress
throttle lever in the process.
4. Check tool speed with tachometer. If tool is operating at a higher
speed than the RPM marked on the tool or operating improperly,
the tool should be serviced to correct the cause before use.
MAINTENANCE INSTRUCTIONS:
1. Check tool speed regularly with a tachometer. If tool is operating at
a higher speed than the RPM marked on the tool, the tool should be
serviced to correct the cause before use.
2. Some silencers on air tools may clog with use.
Clean and replace as required.
3. All Dynabrade Rotary Vane air motors should be lubricated.
Dynabrade recommends one drop of air lube per minute for each 10
SCFM (example: if the tool specifications state 40 SCFM, set the drip rate
of your filter-lubricator at 4 drops per minute). Dynabrade Air Lube
(P/N 95842: 1 pt. 473 ml.) is recommended.
4. 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 Line Filter-Regulator-
Lubricator—Provides accurate air pressure regulation, two-stage filtration
of water contaminants and micro-mist lubrication of pneumatic
components. Operates 40 SCFM @100 PSIG has 3/8" NPT female ports.
5. Lubricate planetary gears through the grease fitting with 2 plunges for
every 50 hours of use, to achieve maximum gear life (order 95542 Grease
and 95541 Gun).
6. Use only genuine Dynabrade replacement parts. To reorder replacement
parts, specify the Model #, Serial # and RPM of your machine.
7. A Motor Tune-Up Kit (P/N 96174) is available which includes assorted
parts to help maintain motor in peek operating condition. Please refer to
Dynabrade's Preventative Maintenance Schedule for a guide to expectant
life of component parts.
8. Mineral spirits are recommended when cleaning the tool and parts.
Do not clean tool or parts with any solvents or oils containing acids,
esters, keytones, chlorinated hydrocarbons or nitro carbons.

motion and overexposure to vibration.
NOTICE
All Dynabrade motors use the highest quality parts and metals 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.
MOTOR ASSEMBLY/DISASSEMBLY
INSTRUCTIONS
Important: Manufacturer's warranty is void if tool is disassembled before
warranty expires.
NOTICE: Dynabrade strongly recommends the use of their 52296 Repair
Collar (sold separately) during assembly/disassembly activities.
Failure to use this collar will highly increase the risk of damage
to the valve body of this tool. Please refer to parts breakdown for
part identification.
MOTOR DISASSEMBLY:
1. Disconnect tool from power source.
2. Secure air tool in vise using 52296 Repair Collar. Remove back-up pad.
3. With an adjustable pin wrench or 50971 Lock Ring Tool, remove 50781
Rear Exhaust Cover by turning counter-clockwise.
4. Remove 50784 Set Screw and pull 50782 Adapter and planetary
carrier assembly from 50776 Housing.
5. Press planetary carrier assembly from rear 54552 Bearing.
Remove ring gear and gears from 50786 or 50787 Planetary Carrier.
6. Secure planetary carrier in vise and remove 50782 Adapter.
Press carrier from front 54552 Bearing.
7. Grab onto pinion and pull motor assembly from motor housing.
Remove 50778 Spacer.
8. Press 54553 or 54554 Rotor from 02673 Rear Bearing Plate. Press 02696
Rear Bearing from rear bearing plate, remove 02679 Shield.
9. Remove cylinder and rotor blades from rotor.
10. Press 54553 or 54554 Rotor through 02649 Front Bearing and 01478
Front Bearing Plate.
MOTOR DISASSEMBLY COMPLETE.
VALVE BODY DISASSEMBLY:
1. Position valve body in vise using 52296 Repair Collar w/air inlet facing up.
2. Remove air fitting by securing 94523 Inlet Adapter with a wrench
and twist air fitting from inlet adapter.
IMPORTANT: 94523 Inlet Adapter must be secured before attempting

VALVE DISASSEMBLY COMPLETE.
MOTOR ASSEMBLY:
IMPORTANT: Be sure parts are clean and in good repair before
assembling. Follow all grease, oil, and torque specifications.
1. Slip 01479 Spacer onto 54553 or 54554 Rotor.
2. Place a .002" Shim into 01478 Front Bearing Plate for initial spacing.
Then slip 02649 Bearing into 01478 Front Bearing Plate.
Press assembly onto rotor.
3. Check the clearance between rotor and bearing plate by using a .001"
feeler gauge. Clearance should be at .001" to .0015". Adjust clearance by
repeating steps 1-3 changing shims as required.
4. Once proper rotor gap clearance is achieved, install lubricated blades into
rotor slots, (use 95842 Dynabrade Air Motor Oil or equivalent).
5. Install 01476 Cylinder so it rests against the 01478 Front Bearing Plate,
(make sure inlet holes of cylinder line up with inlet holes in 02673 Rear
Bearing Plate.
6. Press 02696 Bearing into 02673 Rear Bearing Plate. Press this
assembly onto rotor. Important: Fit must be snug between bearing plates
and cylinder. If too tight, rotor will not turn freely. Rotor must then be lightly
tapped at press end so it will turn freely while still maintaining a snug fit. A
loose fit will not achieve the proper preload or motor bearings. Next, place
a small amount of grease on the 02696 Bearing and stick 02679 Shield
against the bearing.
7. Secure housing in vise using 52296 Repair Collar or padded jaws so that
motor cavity points upward.
8
Install motor assembly into housing, making sure motor drops all the way
into housing.
9. Install 50778 Spacer so that flat side rests against 02649 Bearing.
10. Press front 54552 Bearing onto front end of 50786 or
50787 Planetary Carrier.
11. Hold planetary carrier in a soft jaw vise and apply one drop of #271
Loctite
