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.
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.
• 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 disconnected from air tool, mount types 16, 17, 18, 18R and 19 Cone and plug wheels onto 3/8"-24 UNF-2A Spindle thread.
CONE or PLUG MOUNTING
Typical Mounting for Cone or Plug Wheels
• Blotters must cover at least the adapter surface as shown.
• A blotter (compressible washer) shall always be used between the
abrasive cone or plug surface and the adapter to ensure uniform
distribution of pressure.
• Blotters shall cover the entire adapter contact area.
• New blotters shall be used each time a wheel is mounted unless blotters
are affixed to the cone or plug by the manufacturer.
• Connect air tool to power source. Be careful NOT to depress throttle lever in the process.
Caution:
After installing the accessory, before testing or use and/or after assembling tool, the cone or plug grinder 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.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris.
• Use a vise or clamping device to hold work piece firmly in place.
• Do not apply excessive force on tool or apply "rough" treatment to it.
• Always work with a firm footing, posture and proper lighting.
Report to your supervisor any condition of the tool, accessories, or operation you consider unsafe.
Regulator
Filter
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.
•
Incorporating a refrigerated air dryer after the
compressor and drain valves at each tool station
(as shown) further reduces moisture from
condensation in the air supply.
