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.
• 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.
• BEFORE MOUNTING A ACCESSORY, after all tool repairs and whenever a Dynisher
®
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 RPMmust 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 recommended accessory onto arbor assembly. Dynacushion should be mounted with valve stem accessible
for inflation. Inflate Dynacushion using 94465 Wheel Inflation tool. Inflate only enough to prevent abrasive from slipping or falling off.
DO NOT OVER-INFLATE DYNACUSHION(20 PSIG max.).
• Adjust handle support using 01678 Screw to desired position. The shroud assembly can also be adjusted using (3) 96278 Screw Assemblies to best protect
operator from abrasive debris during use. See Complete Assembly Breakdown for hardware locations.
• 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, before testing or use and/or after reassembling tool, the right-angle Dynisher
®
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.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris.
• Air tools are not intended for use in explosive atmospheres and are not insulated
for contact with electric power sources.
• 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.
• This tool is rear exhaust. Exhaust may contain lubricants, vane material,
bearing grease, and other materials flushed thru the tool.
Warning: Grinding/sanding certain materials can create explosive dust.
It is the employers responsibility to notify the user of acceptable dust levels.
• Grinding can cause sparks which can cause fires or explosions. It is
the users responsibility to make sure the work area is free of flammable materials.
• Contact with abrasive may cause abrasions or cuts.
Report to your supervisor any condition of the tool, accessories,
or operation you consider unsafe.

LUBRICATOR SETTING
• 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.
• Ideally the air supply should be free from moisture.
Incorporating a refrigerated air dryer after the
compressor and drain valves at each tool station
(as shown) further reduces moisture from
condensation in the air supply.

Maintenance Instructions
Important: 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 insure quality. To order replacement parts, specify Model#, Serial# and RPM of your air tool.
• All Dynabrade Rotary Vane air tools must be used with a Filter-Regulator-Lubricator to maintain all warranties. 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 @ 100 PSIG with 1/2" NPT female ports.
• Lubricate wick system through the angle gear oil fitting with 2-3 plunges for every 24
hours of use, to achieve maximum gear life. Important: Use only the recommended
angle gear oil for the wick system. Do not contaminate the wick with any other oil or
grease product (order 95848 Gear oil and 95541 Gun). Lubrication gun should be
upside down during lubrication. (See Fig.1)
• 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, achieve maximum gear life. (See Fig. 2)
• 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.
Routine Preventative Maintenance:
• Check free speed of right-angle Dynisher
®
using a tachometer. This governor controlled right-angle Dynisher®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.
• 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 and hangers are recommended.
• Protect tool inlet from debris (see Notice below).
• DO
NOT carry tool by air hose.
• 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.
One Y ear 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.
