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 which has a 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 A BACK-UP PAD/ABRASIVE, after all tool repairs and whenever a 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.
Warning: Back-up pad speed rating must be approved for at least the tool RPM rating. Check accessory manufacturer for details on maximum operating speed or special mounting instructions.
Back-Up Pad/Abrasive Mounting
• Disconnect air source from the tool.
• Clean spindle and locking flange nut mounting surfaces. Inspect for nicks,
cuts, sharp edges and thread wear.
• Install back-up pad onto spindle (ideal mounting is shown) with abrasive disc mounted
and locking flange nut secured. Spindle end should be flush with locking flange nut with
+ or - 1/16". Spacers may be needed to achieve ideal mounting.
• Check mounting by rotating spindle, make certain abrasive disc is concentrically
mounted and back-up pad is not excessively warped.
• Connect tool to air 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).
Warning: After installing the back-up pad/abrasive, make sure that no one is in the unguarded plane before starting the sander. IN A PROTECTED AREA, test run the sander 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 sander at its free speed (RPM) in a protected
area for at least one minute before use.
• DO NOT engage spindle lock while spindle is rotating.
• 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.
• Always be aware of bystanders in work areas.
• This tool has side exhaust, rotate muffler cover by hand to desired exhaust direction. Exhaust may contain lubricants, vane material, bearing grease, and other materials flushed through the tool.
Warning: Sanding certain materials can create explosive dust. It is the employers responsibility to notify the user of acceptable dust levels. Reduce the risk by using dust collection systems and
personal protective equipment.
• Sanding 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.
• Use side handle provided to best control tool during sanding.
• Release the throttle lever in case of an interruption of the energy supply.

• Check all connections and air hoses for good condition
and proper installation.
• 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 air supply, the
installation of a refrigerated air dryer after the
compressor and the use of drain valves at each
tool station.
