• Follow tool specifications before choosing size and type of accessory.
• Only use recommended fittings and air line sizes. Air supply hoses and air hose accessories must have a minimum working pressure of 150 PSIG (10 Bars, g) or 150 percent of the maximum pressure
produced in the system, whichever is higher. (See tool Machine Specifications table.)
Warning: Always wear personal protective equipment. Operator of tool is responsible for the 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 tool has a potential 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 A BACK-UP PAD, after all tool repairs and whenever a Vacuum Disc Sander 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.
• Disconnect air hose from tool when changing abrasive discs.
Back-Up Pad/Abrasive Mounting
• Disconnect air source from the tool.
• Secure spindle with wrench.
• Thread back-up pad onto spindle securely.
• Check mounting by rotating spindle, make certain abrasive disc is
concentrically mounted and back-up pad is not excessively warped.
• 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 Vacuum Disc Sander 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. Test tool at its free speed (RPM) in a protected area for at least one minute before
applying the tool to the work.
• Release throttle lever when air supply is interrupted.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris.
• 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.
• 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 does not create a hazard.
• USE ONLY ON NON-FERROUS MATERIALS.
• This tool has rear exhaust. Exhaust may contain lubricants, vane material, bearing grease, and other materials flushed thru the tool.
Warning: Sanding certain materials can create explosive dust. It is the employers responsibility to notify the user of acceptable dust levels.
• Sanding certain materials can cause sparks which can cause fires or explosions. It is the users responsibility to make sure the work area is free of flammable materials.
• Always use dust extraction or suppression systems which are suitable for the materials being processed.

90 PSIG
(6.2 Bar)
• 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 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.
