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.

• 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 recommended accessory into collet assembly.
• The mandrel diameter of the abrasive/accessory must insert freely, but not loosely, all the way to the base of the collet body before tightening the collet

cap.  Use wrenches provided.

• 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, the Extension Die 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.

MANDREL MOUNTING

Correctly Mounted

Caution:

The mandrel shall be inserted to the full depth of the gripping jaws of the collet.  At least one-half the mandrel length shall be inserted into the collet
to prevent excessive overhang.  Refer to accessory manufacturer's instructions for proper overhang.  (Ref. ANSI B186.1)

Warning:

Sliding the accessory’s mandrel out from the collet insert creates an “OVER HANG” condition.  This practice is NOT recommended, reducing the
free speed of the tool by reducing the air pressure must be done to avoid cutting tool breakage and serious injury.

LUBRICATOR SETTING

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.
