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 bushing 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. An Air line Filter-Regulator-Lubricator must be used with this air tool to maintain all warranties. Dynabrade recommends the following: 11405 Air Line Filter-Regulator-

Lubricator — Provides accurate air pressure regulation, two-stage filtration of water contaminant's and micro-mist lubrication of pneumatic components. Operates up to 40
SCFM @ 100 PSIG has 3/8" NPT female ports.

5. Lubricate wick system through the angle gear head gear oil fitting with 2-3 plunges for every 8 hours of use, to achieve maximum gear life. Important: Use only the
recommended angle gear oil for the wick system. Do not contaminate the wick with any other oil or grease product (order 95848 Gear Oil and 95541 Gun).

6. Lubricate planetary gears through the gear casing grease fitting with 2-3 plunges for every 50 hours of use, to achieve maximum gear life (order
95542 Grease and 95541 Gun).

7. Use only genuine Dynabrade replacement parts. To reorder replacement parts, specify the model #, Serial #, and RPM of your machine.

8. A Motor Tune-Up Kit (P/N 96179) 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.

9. 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.

• Important: User of tool is responsible for following accepted safety codes such as those published by the American National Standards Institute (ANSI).

• Operate machine for one minute before application to workpiece to determine if machine is working properly and safely before work begins.

• Always disconnect power supply before changing abrasive/accessory or making machine adjustments.

• Inspect abrasives/accessories for damage or defects prior to installation on tools.

• Please refer to Dynabrade’s Warning/Safety Operating Instructions Tag (Reorder No. 95903) for more complete safety information.

• Warning: Hand, wrist and arm injury may result from repetitive work, 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.

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.

Safety Instructions:

Products offered by Dynabrade should not be converted or otherwise altered

Disassembly/Assembly Instructions - Right-Angle Tools

Important: Manufacturer’s warranty is void if tool is disassembled before warranty expires. Please refer to parts breakdown for part identification.
Special repair tools are mentioned in these instructions. These can be ordered from Dynabrade

®

through your Dynabrade®Distributor.

Motor Disassembly:

1. Disconnect the tool from the air supply. Important: Hold the air inlet adapter securely with a wrench before removing any air fitting to prevent damage to the composite housing.

2. Secure the motor housing in a vise using 52296 Repair Collar or padded jaws to provide protection for the housing. Position the tool so that the angle-head is pointing up.

3. Use a 34 mm or adjustable wrench to remove the 50024 Gear Case, turning it counter clockwise.

4. Pull motor assembly out of the motor housing.

5. Fasten a 2 in. bearing separator around the portion of the 01476 Cylinder nearest the 02676 Rear Bearing Plate.

6. Place the bearing separator on the table of the arbor press so that the sun gear end of the rotor is pointing toward the floor.
