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 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.

Operating Instructions:

Warning:

Eye, face, sound, respiratory 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.

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 lubrication. Dynabrade recommends the following: 

11405

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 40 SCFM @ 100 PSIG has 3/8" NPT female port.

5.

Lubricate planetary gear case with gear oil fitting with 2-3 plunges every 

8 hours

of use for maximum gear life. 

Important:

Use recommended gear oil

only. 

Do not contaminate with any other oil or grease product (Order 95848 Gear Oil and 95541 Gun)

.

6.

Use only genuine Dynabrade replacement parts. To reorder replacement parts, specify the 

Model #

Serial #

and 

RPM

of your machine.

7.

A Motor Tune-Up Kit (P/N 

96533

) 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.

8.

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).

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.

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.
