OPERATING INSTRUCTIONS
Warning: Always wear eye protection. Operator of tool is responsible for following: accepted eye, face, respiratory, hearing and body protection.
Caution: Hand, wrist and arm injury may result from repetitive work, motion and overexposure to vibration.
Warning: Be sure that any loose clothing, hair and all jewelry is properly restrained.
• Keep hand and clothing away from moving end of the air tool which has a potential hazard of cutting and severing.
• 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.
Warning: Regularly check free speed (RPM) of random orbital 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 the tool running. Checking the RPM requires either a strobe or magnetic tachometer. This
procedure is required after all tool repairs and whenever a tool is issued for use. If 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.
Warning: Tool RPM must never exceed abrasive/accessory RPM rating. Check accessory manufacturer for details on maximum operating speed or
special mounting instructions.
Warning: Do not free spin the tool away from the work surface with an abrasive sanding disc attached. The sanding disc may detach from the back-up pad causing injury.
Warning: Always start the tool with the sanding abrasive against the work. Stop the air flow to the tool as it is removed from the work.
• With power source connected at the air tool relieve hose of air pressure and disconnect tool from air supply when changing recommended accessories.
• Connect air tool to power source. Be careful NOT to depress throttle lever in the process.
Do not expose air tool to inlet pressure above 90 PSIG or (6.2 Bars).
Caution: After installing the accessory, before testing or use and/or after reassembling tool, the tool must be started at a reduced speed to check for good balance. Gradually
increase tool speed. DO NOT USE if tool vibration is excessive. Correct cause, and retest to insure safe operation.
Warning: Use only appropriately sized abrasive sanding discs properly secured and centered to the backing pad provided with the air sander.
• DO NOT USE grinding wheels or cutting-off wheels.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris.
Warning: Potentially explosive atmospheres can be caused by dust and fumes resulting from sanding or grinding. Always use dust extraction or suppression systems which are
suitable for the material being processed.
• Proceed with caution in unfamiliar surroundings. Hidden hazards may exist, such as electricity or other utility lines.
• Use only Dynabrade weight-mated pads to maintain low vibration levels.
• Use a vise or clamping device to hold work piece firmly in place.
• Work may generate hazardous dust.
• Always be aware of bystanders in work areas.
• Do not apply excessive force on tool or apply “rough” treatment to it.
• Always work with a firm footing, posture and proper lighting.
• Release the throttle lever in case of an interruption of the energy supply.
• Ensure that sparks and debris resulting from work do not create a hazard such as fire or explosion.
• This tool is rear exhaust. Exhaust may contain lubricants, vane material, bearing grease, and other materials flushed through the tool.
Report to your supervisor any condition of the tool, accessories, or operation you consider unsafe.

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 ensure 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: Check free speed of Dynorbital-Spirit
®
regularly using a strobe or magnetic tachometer without abrasive accessory
attached with 90 PSIG at inlet while tool is running. Always check tool speed after any maintenance or repair. If tool is operating at a higher RPM (speed)
than marked on the housing, or operating improperly, the tool must be 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 Drop-In Motor and Tune-Up Kit are 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.:

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.
Lifetime Warranty
All Dynabrade portable pneumatic power tools are rigorously inspected and performance tested in our factory before shipping
to our customers. If a Dynabrade tool develops a performance problem and an inherent defect is found during normal use and
service, Dynabrade will warrant this tool against defects in workmanship and materials for the lifetime of the tool. Upon
examination and review at our factory, Dynabrade shall confirm that the tool qualifies for warranty status, and will repair or
replace the tool at no charge to the customer. Normally wearable parts and products are NOT covered under this warranty.
Uncovered items include bearings, contact wheels, rotor blades, regulators, valve stems, levers, shrouds, guards, O-rings,
seals, gaskets and other wearable parts. Dynabrade’s warranty policy is contingent upon proper use of our tools in accordance
with factory recommendations, instructions and safety practices. It shall not apply to equipment that has been subjected to
misuse, negligence, accident or tampering in any way so as to affect its normal performance. To activate lifetime warranty,
customer must register each tool at www.dynabrade.com. Dynabrade will not honor lifetime warranty on unregistered tools. A
one-year warranty will be honored on all unregistered portable pneumatic power tools. Lifetime warranty applies only to portable
pneumatic tools manufactured by Dynabrade, Inc. in the USA. Lifetime warranty applies only to the original tool owner; warranty
is non-transferable.
