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. Air tools are not intended for use in explosive atmospheres and are not insulated for contact with electrical power sources.
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 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 peak 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.

®
Important: Manufacturer’s warranty is void if tool is disassembled before warranty expires. Notice: Dynabrade recommends the use of the 52296 Repair Collar (sold separately) during the disassembly and assembly of the Right-Angle Mini-Dynorbital Sander. All of the special tooling referred to in these instructions can be ordered from Dynabrade. Please refer to the parts page for the proper part identification.
Motor Disassembly:
1. Shut the air supply and disconnect the sander from the air supply hose. Important: Hold the air inlet adapter with a wrench before removing the air fitting so as to prevent damage to the composite housing.
2. Hold the motor housing in a vise by using the 52296 Repair Collar to provide protection for the housing. Position the tool so that the angle head is pointing up.
3. Use a 34mm or an adjustable wrench to remove the 50024 Gear Case by turning it counterclockwise.
4. Pull the motor assembly out of the motor housing.
5. Fasten the 96346, 2" Bearing Separator around the portion of the 01476 Cylinder that is closest to the 02676 Bearing Plate.
6. Place the bearing separator on the table of the 96232, #2 Arbor Press so that the gear end of the rotor is pointing toward the floor.
7. Use a 3/16" dia. flat end drive punch as a press tool to push the rotor out of the 02696 Bearing. The 02696 Bearing can be removed from the 02676 Bearing Plate with the 96210 Bearing Removal Tool and the arbor press.
