Maintenance Instructions

Important:

To keep tool safe 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: 

10681

Air Filter-Regulator-Lubricator (FRL) – Provides accurate

air pressure regulation and two stage filtration of water contaminates.

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:

Regularly check the free speed (RPM) of the Mini-Dynorbital

®

Silver Supreme Sander. The speed (RPM) is checked with the back-up pad securely

fastened without any type of sanding accessory attached to the back-up pad. The air pressure must be set to 90 PSIG with tool running. Checking the 
RPM requires either a strobe or a magnetic tachometer. This procedure is required after all tool repairs and whenever a tool is issued for use. If the tool 
is operating at a higher speed than the RPM marked on the tool housing, or operating improperly, the tool must be serviced and corrected before use.

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 Tune-Up Kit is available, see specific kit number on page 7.

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.
