MAINTENANCE INSTRUCTIONS
Important: To keep tool safe, a Preventative Maintenance Program is
recommended. The program should include inspection of the tool and all
related accessories and consumables, including air lines, pressure regulators,
filters, oilers, etc. (refer to CAGI B186.1 for additional maintenance
information). If accessory or tool breakage occurs, investigate failure to
determine the cause and correct before issuing tool for work. Use the following
schedule as a starting point in developing a Preventative Maintenance
Program. If tool does not operate properly (RPM, vibration, start/stop) after
these scheduled checks or at any time, the tool must be repaired and
corrected before returning tool to use.
INSTALLATION
• To ensure long life and dependable service, use a Closed Loop Air System
and Filter-Regulator-Lubricator (FRL) as diagramed below.
• Each tool should have its own dedicated hose connected to an air supply
FRL. Quick disconnects should be installed at the FRL in an effort to reduce
contamination into the tool. Securely affix all fittings and hose assemblies.
• 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.
• Dynabrade recommends 1 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). 95842 Dynabrade Air Lube
is recommended.
MAINTENANCE SCHEDULE
Maintenance schedules depend on the type and style of tool. Refer to page
3 to reference symbols associated with specific maintenance items/areas.
Match maintenance schedules accordingly. See page 4 for any additional
maintenance information.
Note: Turbine style air motors do not require oil.
Daily (every 8 hours):
• Inspect tool and accessories for damage or broken parts. Replace items
as necessary to ensure proper operation and safety.
Lubricate motor as recommended. Use 95842 Dynabrade Air Lube
(10W/NR). Apply 1 drop/minute of air lube per 20 SCFM.
• Check air line pressure with a gage. (MAX. 90 PSIG or 6.2 Bar operating
pressure at the air inlet of the tool.)
Lubricate wick system and right angle gears through gear case
fitting. Apply 3 plunges of 95848 Gear Oil. Use 95541 Lubricant Gun
(Prime lubricant gun before use).
• Check tool for proper operation: If operating improperly or demonstrates
unusual vibration, the tool must be serviced and problem corrected before
further use.
Every 20 Hours/Once a Week (which ever comes first):
• Measure RPM (speed) by setting air pressure to 90 PSIG (6.2 Bar) at tool
inlet, without accessory mounted, while the tool is running. Using
tachometer, check spindle speed of the tool. Unless otherwise stated the
no-load speed may not exceed the rated speed. If tool speed exceeds
maximum rated RPM, service as required and correct before use.
• If tool is running too fast: look for worn, damaged or missing governor, air
control rings and silencer(s). Service as required.
• If tool is running too slow: look for malfunctioning governor, clogged inlet
screen, silencer(s) or air stream. Service as required.
Note: Special care must be taken when servicing governors. Refer to specific
tool manual for governor instructions and/or speed control devices. Governor
assemblies made from molded plastic components are non-serviceable and
must be replaced.
Every 50 Hours:
Lubricate planetary gears through gear case fitting with 3 plunges
of 95542 Grease. Use 95541 Lubricant Gun. (Prime lubricant gun
before use).
REPAIR
• Use only genuine Dynabrade replacement parts to ensure quality. To order
replacement parts, specify Model#, Serial# and RPM of your air tool.
• 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.
• A Motor Tune-Up Kit 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.
After maintenance is performed on tool, add a few drops of 95842
Dynabrade Air Lube to the tool inlet and start the tool a few times to
lubricate air motor. Verify RPM (per 20 hr maintenance schedule),
vibration and operation.
HANDLING & 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.
• Store accessories in protective racks or compartments to prevent damage.
• Follow the handling instructions outlined in the operating instructions when
carrying the tool and when changing accessories.
• Protect accessories from exposure to water, solvents, high humidity,
freezing temperature and extreme temperature changes.
END OF USE/ DISPOSAL
When tool has reached its end of useful service, disassemble tool into its
primary components (i.e. steel, aluminum and plastic) and recycle or discard
per local, state and/or federal regulations as to not harm the environment.
NOTICE
All Dynabrade air motors use the highest quality parts available and are
manufactured to exacting tolerances. Air motor failures are often traced to lack
of lubrication or unclean air supply. Compressed air can force dirt and other
contaminants into motor bearings causing early failure. Contaminants can score
cylinder wall and vanes resulting in reduced efficiency and power. Our warranty
obligation is contingent upon proper use of our tools. Air motors which have been
subjected to misuse, contaminated air or lack of lubrication will void warranty.

• 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.
