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.

• Keep hand and clothing away from working end of the air tool.
• Working end of the air tool has potential hazard of cutting and severing.

Operation:

Be sure that any loose clothing, hair and all jewelry is properly restrained.

• Secure inlet bushing on air tool with a wrench before attempting to install the air fitting to avoid damaging housing assembly.
• BEFORE MOUNTING AN ACCESSORY, after all tool repairs and whenever a 8" Random Orbital Polisher is issued for use, check tool RPM 

(speed) with tachometer with air pressure set at 90 PSIG while the tool is running. 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.

Caution:

Tool RPM must never exceed abrasive/accessory RPM rating. Check accessory manufacturer for details on maximum operating speed or special
mounting instructions.

• 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 assembling tool, the 8" Random Orbital Polisher 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.

• Release the throttle lever in case of an interruption of the energy supply.
• Ensure that self-fixing accessories are mounted concentrically.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris. 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.
• Air tools are not intended for use in explosive atmospheres and are not insulated for contact with electric power sources. 
• Use a vise or clamping device to hold work piece firmly in place.
• Work may generate hazardous dust.
• Do not apply excessive force on tool or apply “rough” treatment to it.
• Always work with a firm footing, posture and proper lighting.
• Ensure that sparks and debris resulting from work do not create a hazard.
• This tool is rear exhaust. Exhaust may contain lubricants, vane material, bearing grease, and other materials flushed thru the tool.

Report to your supervisor any condition of the tool, accessories, or operation you consider unsafe.

LUBRICATOR SETTING

Dynabrade Air Power Tools are designed to
operate at 90 PSIG (6.2 Bar/620 kPa) maximum
air pressure at the tool inlet, when the tool is
running. Use recommended regulator to control
air pressure.

Ideally the air supply should be free from moisture.
To facilitate removing moisture from the air supply,
the installation of a refrigerated air dryer after the
compressor and the use of drain valves at each
station is recommended.
