• Before mounting an accessory, visually inspect for defects. Do not use defective accessories.
• Use only accessories of the correct shaft size for the collet.
• Follow tool specifications before choosing size and type of accessory.
• Only use recommended fittings and air line sizes. Air supply hoses and air hose assemblies must have a minimum working pressure rating 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.)
• If a grinding wheel is broken, a careful investigation should be made by the user to determine and correct the cause.
Warning: Always wear personal protection equipment. Operator of tool is responsible for following: accepted eye, face, respiratory, hearing and
body protection. Adjacent personnel must be protected from potential injury.
Caution: Hand, wrist and arm injury may result from repetitive work, motion and overexposure to vibration.
Operation: Be sure that any loose clothing, hair and all jewelry is properly restrained. Keep hand and clothing away from working end of the air tool.
• BEFORE MOUNTING AN ACCESSORY, after all tool repairs and whenever a pencil grinder 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.
• With power source disconnected from air tool check the collet to assure it is in good condition. If so mount the recommended accessory.
• Make sure tool is off and connect power source.
Do not expose air tool to inlet pressure above 90 PSIG or (6.2 Bars).
• This tool should use filtered and regulated air, but does not require lubricated air. Lubricated air is not detrimental to tool life.
Caution: After installing the accessory, before testing or use and/or after assembling tool, the pencil grinder must be started at a reduced speed to check
for good balance. Make sure no one is in the unguarded plane of the wheel. Gradually increase tool speed. DO NOT USE if tool vibration is
excessive. Correct cause, and retest to insure safe operation. Run tool for 1 minute of operating speed in a protected area.
• 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.
• Ensure that sparks and debris resulting from work do not create a hazard.
• Tools exhaust may contain lubricants, bearing grease, and other materials. Direct exhaust away from operator.
• Do not use cut off wheels or router bits in this tool.
• Make sure that insert tools have the correct shaft size for the collet insert. i.e. 1/8" shaft = 1/8" collet insert
• Note the tool rundown time. Control the tool as if it were under power.
• Insure that the cutting tools are mounted securely in the collet, by inserting the shank a minimum of 1in., sliding the o-ring away from the cross holes and
groove in housing, fixing the spindle with the supplied pin wrench and tightening the collet with a minimum of 25 in.- lbs. (2.8 N•m) torque.
• Insure that the pin wrench is clean and free of debris before inserting into tool housing.
• Use long shank burrs (1.9" or longer) with caution. They are subject to bending, whipping, and breaking when run at high speeds.
• The rated RPM of a mounted point is lowered if the overhang (end of collet to abrasive) exceeds .5 inches (12.7mm).
Refer to the included tables. Reference ANSI B 7.1 for a more complete listing and additional information.
• Use hearing protection when working with materials that produce high process noise levels. Permanent hearing loss can result from high sound levels.
• Check free speed of pencil grinder using a tachometer every 20 hours of use or weekly, whichever occurs more frequently.
• Mineral spirits are recommended when cleaning the tool and parts. Do not clean tool or parts with any solvents or oils containing acids, esters,
ketones, chlorinated hydrocarbons or nitro carbons.
• Do Not set the tool down until the on/off valve is OFF and the tool has stopped turning.
Report to your supervisor any condition of the tool, accessories, or operation you consider unsafe.
Important: A Preventative Maintenance Program is recommended for this tool. The program should include inspection of air supply lines, air line pressure
and repair of tools. Refer to ANSI B186.1 for additional maintenance information.
• Use only genuine Dynabrade replacement parts to insure quality. To order replacement parts, specify Model#, Serial# and RPM of your air tool.
• All Dynabrade Air Tools must be used with a Filter-Regulator to maintain all warranties.
Routine Preventative Maintenance:
• An Air Line Filter-Regulator must be used with this air tool to maintain all warranties. Dynabrade recommends the following: 11402 Air Line
Filter-Regulator – Provides accurate air pressure regulation, two-stage filtration of water contaminates. Operates 40 SCFM @ 90 PSIG has
3/8" NPT female ports.
• DO NOT clean or maintain tools with chemicals that have a low flash point (example: WD-40
• Air tool markings must be kept legible at all times. User is responsible for maintaining specification information i.e.: Model #, S/N, and RPM.
• Blow air supply hose out prior to initial use.
• Visually inspect air hoses and fittings for frays, visible damage and signs of deterioration. Replace damaged or worn components.
• Refer to Dynabrade's Warning/Safety Operating Instructions Tag (Reorder No. 95903) for safety information.
Handling and Storage:
• Use of tool rests, hangers and/or balancers is recommended.
