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 air tools must be used with a Filter-Regulator-Lubricator to maintain all warranties.

Operating Instructions:

Warning:

Eye, face 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 air motors should be lubricated. Dynabrade recommends one drop of air lube per minute for each 10 SCFM (example : if the tool

specification state 40 SCFM, set the drip rate of your filter-lubricator at 4 drops per minute). Dynabrade Air Lube (P/N 95842: 1pt. 473ml.) is recommended.

4. An air line filter-regulator-lubricator must be used with this air tool to maintain all warranties. Dynabrade recommends the following: 11411 Air Line Filter-

Regulator-Lubricator — Provides accurate air pressure regulation, two-stage filtration of water contaminants and micro-mist lubrication of pneumatic

components. Operates up to 100 CFM @ 100 PSI has 1/2" NPT female ports.

5. Lubricate planetary gears through 50970 Gear Casing grease fitting ever 50 hours of use for maximum gear life.

6. Lubricate 02048 Wick System through angle gear head grease fitting ever 8 hours of use for maximum gear life. Important: Use recommended

angle gear oil only for wick system. Do not contaminate wick with any other oil or grease product (Order 95848 Gear Oil 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 96178) 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. A lubrication accessory kit (P/N 50790) is available which contains Dynabrade's 95542 Grease, 95541 Lubrication Gun (2) and 95848 Gear Oil.

10. 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.

•

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.

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.
