Some dust created by sanding, sawing, grinding, drilling, and other construction activities contain chemicals known to cause cancer,
birth defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement and other masonry products
• Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

SAFETY INSTRUCTIONS (Cont.)
• 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.
OPERATING INSTRUCTIONS
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.
MAINTENANCE INSTRUCTIONS
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.
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. Air pressure easily forces dirt or water contained in the air supply into motor bearings causing early failure. Dirt
and water often score the inner workings of the tool 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 maintenance during the use of this tool.
One Year Warranty
Following the reasonable assumption that any inherent defect which might prevail in a product will become apparent to the user within one year from the
date of purchase, all equipment of our manufacture is warranted against defects in workmanship and materials under normal use and service. We shall
repair or replace at our factory, any equipment or part thereof which shall, within one year after delivery to the original purchaser, indicate upon our
examination to have been defective. Our obligation is contingent upon proper use of Dynabrade tools in accordance with factory recommendations,
instructions and safety practices. It shall not apply to equipment which has been subject to misuse, negligence, accident or tampering in any way so as to
affect its normal performance. Normally wearable parts such as bearings, contact wheels, rotor blades, etc., are not covered under this warranty.

Air System
•
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 at each work station, if the supply
pressure is high.
•
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.
