OPERATING INSTRUCTIONS
Warning: Always wear eye protection. Operator of tool is responsible for following: approved eye, face, respiratory, hearing and body protection.
Caution: Hand, wrist and arm injury may result from repetitive work, motion and overexposure to vibration.
Warning: 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 or remove 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 accessory RPM rating. Check accessory manufacturer for details on maximum operating speed or special mounting instructions.
• Before mounting an accessory regularly clean and inspect collet assembly parts for wear or damage. DO NOT use worn or damaged components.
• With power source disconnected from air tool, mount recommended accessory into collet assembly.
• The mandrel diameter of the 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.
• After accessory change or height adjustment, reposition the throttle lever to best protect operator from unintentional starts.
• When adjusting bases/guides make sure the collet nut and any other adjustment devices are securely tightened.
• 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 router 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.
• Keep hand and clothing away from working end of the air tool.
• Working end of tool has a potential of cutting and severing.
• 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.
• Use a vise or clamping device to hold work piece firmly in place.
• Tool is rear exhaust. Exhaust may contain lubricants, vane material, bearing grease and other materials flushed through tool.
• When routing end grain the router bit can grab the work piece, causing the operator to lose control. Use jigs whenever possible.
• Kickback may occur when operating the router at slow speeds. Make sure the work piece is secure.
• Hold the router firmly with both hands. The reaction torque of the motor can cause the tool to twist.
• Always make sure the work surface is free from foreign objects. Cutting into a dissimilar material can cause the bit and the tool to jump and damage the bit.
• Never start the tool when the bit is touching the workpiece. The bit may grab the workpiece and cause loss of control.
• Always feed the bit into the workpiece in the same direction as the bit rotation.
• Feeding the tool in the wrong direction causes the cutting edge of the bit to climb out of the work piece and pull the tool toward the operator.
• DO NOT force the power tool. Use the tool at its designed speed. Guide in a smooth constant motion.
• DO NOT let the airline impede operating motion.
Warning: Grinding certain materials can create explosive dust. It is the employers responsibility to notify the user of acceptable dust levels.
• Grinding 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 and personal protective equipment which are suitable for the materials being processed.
• Always work with a firm footing, posture and proper lighting.
• Turn off router after cut has been completed, be cautious of run down time of accessory.
Report to your supervisor any condition of the tool, accessories, or operation you consider unsafe.
Air System
CORRECT MANDREL MOUNTING
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.
• When bits are fully inserted, a minimum of 1" in the collet,
the remaining exposed shaft must NOT exceed 1/4".

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.
To install or remove the router bit:
Disconnect tool from air supply.
• Use a 3/16" hex key to loosen the collar adapter screw. Remove the vacuum base.
• Use a 14 mm and a 19 mm open end wrench to install or remove the router bit.
• Install and secure the vacuum base.
• Adjust the router bit depth of cut.
Notice
All Dynabrade motors use the highest quality parts and metals available and are machined to exacting tolerances. The failure of quality pneumatic motors can most
often be traced to an unclean air supply or the lack of lubrication. Air pressure easily forces dirt or water contained in the air supply into motor bearings causing early
failure. Dirt often scores the cylinder walls and the rotor blades resulting in limited efficiency and power. Our warranty obligation is contingent upon proper use of our
tools and cannot apply to equipment which has been subjected to misuse such as unclean air, wet air or a lack of lubrication during the use of this tool.
