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.

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