Important: 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.

• All Dynabrade Rotary Vane air tools must be used with a Filter-Regulator-Lubricator to maintain all warranties. Dynabrade recommends the following:

11411 Air Filter-Regulator-Lubricator (FRL) – Provides accurate air pressure regulation and two stage filtration of water contaminants. Operates 55

SCFM/1,558 LPM @ 90 PSIG with 1/2" NPT female ports.

• Dynabrade recommends one drop of air lube per minute for each 10 SCFM (example: if the tool specification states 40 SCFM, set the drip rate on the

filter-lubricator to 4 drops per minute). Dynabrade Air Lube (P/N 95842: 1 pt 473 ml) is recommended.

Routine Preventative Maintenance: Check free speed of grinder using a tachometer. This governor controlled grinder should be speed checked every 20

hours of use or weekly, whichever occurs more frequently.

• DO NOT disassemble the governor for any reason. Reorder correct speed – governor assembly (See Assembly Breakdown) and recheck free speed of

tool with a tachometer.

• 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 Motor Tune-Up Kit (P/N 96532) is available which includes high wear and medium wear motor parts.

• Air tool labels must be kept legible at all times, if not, reorder label(s) and replace. (See Assembly Breakdown)

• Blow air supply hose out prior to initial use.

• DO NOT carry tool by air hose or near the tool throttle lever.

• 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:

• Use of tool rests, hangers and/or balancers is recommended.

• Protect tool inlet from debris (See Notice Below).

• DO NOT carry tool by air hose.

• Protect cut-off wheels from exposure to water, solvents, high humidity, freezing temperatures and extreme temperature changes.

• DO NOT USE cut-off wheels that have been dropped or show signs of cracks, nicks or other defects.

• Store accessories in protective racks or compartments to prevent damage.

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.

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.
