SAFETY INSTRUCTIONS
(Continued)
• Before mounting an accessory, visually inspect for defects. Do not use defective accessories.
• Follow tool specifications before choosing size and type of accessory.
• Only use recommended fittings and air line sizes. Air supply hoses and air hose assemblies must have a minimum working pressure rating of 150 PSIG
(10 bars) or 150 percent of the maximum pressure produced in the system, whichever is higher.
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. A vibration level of 19.4 (m/s^2) was established.
• DO NOT use quick disconnect coupling at tool. Always separate tool from quick disconnect coupling with at least 12" of air hose.
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 (SPM) of Long Board Sander. The speed (SPM) 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 SPM requires a strobe
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 SPM
marked on the tool housing, or operating improperly, the tool must be serviced and corrected before use.
Warning:
Tool must never exceed abrasive/accessory SPM rating. Check accessory manufacturer for details on maximum operating speed or special
mounting instructions.
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 abrasives properly secured and centered to the backing pad provided with the Long Board Sander.
• 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 lubricants. See Maintenance Instructions.
• 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 a fire or explosion.
• Exhaust air may contain lubricants, 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
•
Dynabrade Air Power Tools are designed to operate at
90 PSIG (6.2 Bar) 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 air supply, the installation
of a refrigerated air dryer after the compressor and the use
of drain valves at each tool station is recommended.
