(6.2 Bar)
• 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.
Important: To keep tool safe a Preventative Maintenance Program is recommended whenever portable power tools are used. The program should include
inspection of air supply lines, air line pressure, proper lubrication and repair of tools. Refer to ANSI B186.1 for additional maintenance information.
• Use only genuine Dynabrade replacement parts to ensure 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: 10681 Air Line Filter-Regulator-Lubricator — Provides accurate air
pressure regulation, two-stage filtration of water contaminants and micro-mist lubrication of pneumatic components. Delivers up to 55 SCFM/1,558 LPM
@ 145 PSIG/9.7 Bar (Max. Air Temperature of 140˚F/60˚ C) Note: Two (2) 3/8" NPT Reducer Bushings are included.
• 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.
Specific Routine Preventative Maintenance - 20,000, 25,000 and 30,000 RPM Governed Tools: Check free speed tool using a tachometer without accessory
mounted. This governor controlled die grinder should be speed checked every 20 hours of use or weekly, whichever occurs more frequently after maintenance or repair.
• 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.
Specific Routine Preventative Maintenance - 35,000 RPM Non-Governed Tools:
• Check free speed of tool regularly using a tachometer without the abrasive accessory mounted. After all tool repairs and whenever a .4 hp Die 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, operating improperly or demonstrates unusual vibration, the tool must be serviced and corrected before use.
Routine Preventative Maintenance
• Inspect accessories before mounting. Do not mount accessories that are damaged or nicked.
• Check accessory - speed rating. Rating on accessory must be greater than the tool speed marked on the housing.
• If accessory breakage occurs, investigate to determine the cause and correct before issuing tool for work.
• 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 96541) is available which includes high wear and medium wear motor parts.
• Air tool markings must be kept legible at all times, if not, reorder housing 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 tool inlet and start the tool a few times to lubricate air motor.
Check for tool vibration before mounting abrasive wheel accessory.
Handling and Storage:
• Use of tool rests, hangers and/or balancers is recommended.
• Protect tool inlet from debris (see Notice on Page 7).
• DO NOT carry tool by air hose or near the tool throttle lever.
• Protect accessories from exposure to water, solvents, high humidity, freezing temperature and extreme temperature changes.
• DO NOT USE accessories that have been dropped or show signs of cracks, nicks or other defects.
• Store accessories in protective racks or compartments to prevent damage.
