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 types 16, 17, 18, 18R and 19 Cone and plug wheels onto 3/8"-24 UNF-2A Spindle thread.

• 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 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.

• Release the throttle lever in case of an interruption of the energy supply.

• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris. Potentially explosive atmospheres can be caused by dust and fumes resulting from sanding or grinding. Always use dust extraction or suppression systems which are suitable for the material being processed.

• Ensure that sparks and debris resulting from work does not create a hazard.

• Use a vise or clamping device to hold work piece firmly in place.

• To reduce operator fatigue use 53199 Collar to mount to suspension device.

• 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.

•

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.

➤

CONE or PLUG MOUNTING

Typical Mounting for Cone or Plug Wheels

• Inspect abrasive, spindle thread and spindle adapter for wear or damage.

• Blotters must cover at least the adapter surface as shown.

• A blotter (compressible washer) shall always be used between the abrasive cone or plug surface and the adapter to ensure uniform distribution of pressure.

• New blotters shall be used each time a wheel is mounted unless blotters are affixed to the cone or plug by the manufacturer.

Maintenance Instructions

Important: To keep tool safe a preventative maintenance program is recommended whenever portable power tools are used.

•

Use only genuine Dynabrade replacement parts to insure quality. To order replacement parts, specify Model#, Serial# and RPM of your air tool.

•

It is strongly recommended that all Dynabrade rotary vane air tools be used with a Filter-Regulator-Lubricator to minimize the possibility of misuse due to unclean air, wet air or insufficient lubrication. Dynabrade recommends the following: 11411 Air Filter-Regulator-Lubricator (FRL) – Provides accurate air pressure regulation and two stage filtration of water contaminants. Operates 55 SCFM/1,558 LPM @ 90 PSIG with 1/2" NPT female ports.

•

Dynabrade recommends one drop of air lube per minute for each 20 SCFM (example: if the tool specification states 40 SCFM, set the drip rate on the filter-lubricator to 2 drops per minute). Dynabrade Air Lube (P/N 95842: 1 pt 473 ml) is recommended.

•

Grease the planetary gear assembly with the 95542 Grease by applying 2-3 plunges with the 95541 Grease Gun after every 50 hours of use for maximum gear life.

Routine Preventative Maintenance: Check free speed of Extension Grinder using a tachometer. This governor controlled grinder should be speed checked every 20 hours of use or weekly, whichever occurs more frequently.

•

DO NOT disassemble the governor for any reason. Reorder correct speed – governor assembly (See Assembly Breakdown) and recheck free speed of tool with a tachometer.

•

Inspect flanges and spindle/spindle adapter threads for wear or damage.

•

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 clean or maintain tools with chemicals that have a low flash point (example: WD-40

•

A Motor Tune-Up Kit (P/N 96532) is available which includes high wear and medium wear motor parts.

•

Air tool labels must be kept legible at all times, if not, reorder label(s) and replace. User is responsible for maintaining specification information i.e.: Model #, S/N, and RPM. (See Assembly Breakdown)

•

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.

After maintenance is performed on tool, add a few drops of Dynabrade Air Lube (P/N 95842) to the air line and start the tool a few times to lubricate air motor. Check for excessive tool vibration.

Handling and Storage:

•

Use of tool rests, hangers and/or balancers is recommended.

•

Protect tool inlet from debris (see Notice below).

•

DO NOT carry tool by air hose or near the tool throttle lever.

•

Protect abrasive accessories from exposure to water, solvents, high humidity, freezing temperature and extreme temperature changes.

•

Store accessories in protective racks or compartments to prevent damage.

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. It 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.
