SAFETY INSTRUCTIONS
Carefully Read all instructions before operating or servicing any Dynabrade®Abrasive Power Tool.
Products offered by Dynabrade are not to be modified, converted or otherwise altered from the original design.
DO NOT USE tool for anything other than its intended applications.
Training: Proper care, maintenance, and storage of your air tool will maximize tools performance and reduce chance for accident.
Employer's Responsibility: Provide operators with safety instructions and training for safe use of tools and accessories.
REPORT TO YOUR SUPERVISOR ANY CONDITION OF THE TOOL, ACCESSORIES, OR OPERATION YOU CONSIDER UNSAFE.
Read and understand tool manual before
work starts to reduce risk of injury to
operator, visitors, and tool.
Eye protection must be worn
at all times, eye protection to
conform to ANSI Z87.1.
Respiratory protection to be used when
exposed to contaminants that exceed the
applicable threshold limit values required by law.
Air line hazard, pressurized supply lines and flexible
hoses can cause serious injury. Do not use damaged,
frayed or deteriorated air hoses and fittings.
WARNING
Ear protection to be worn when exposure to sound,
exceeds the limits of applicable Federal, State or local
statues, ordinances and/or regulations.
Read and understand this tool manual before operating your air tool. Follow all safety rules for the protection of operating personnel as well
as adjacent areas. Always operate, inspect and maintain this tool in accordance with the American National Standards Institute (ANSI) Safety
Code for Portable Air Tools – B186.1. For additional safety information, refer to Safety Requirements for the Use, Care and Protection of Abrasive Wheels – ANSI B7.1, Code of Federal Regulation – CFR 29 Part 1910, European Committee for Standards (EN) Hand Held Non-Electric
Power Tools – Safety Requirements and applicable State and Local Regulations.
Some dust created by sanding, 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.
Practice safety requirements. Work alert,
have proper attire, and do not operate tools under
the influence of alcohol or drugs.

• 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.

OPERATING & MAINTENANCE INSTRUCTIONS
Important: To keep tool safe, a Preventative Maintenance Program is recommended. The program should included inspection of the tool and all related
accessories and consumables, including air lines, pressure regulators, filters, oilers, etc. refer to ANSI 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 as diagramed below.
• Each tool should have its own dedicated hose connected to an air supply manifold. Quick disconnects should be installed at the manifold in an effort to
reduce contamination into the tool.
• It is strongly recommended that all Dynabrade air tools be used with a Filter-Regulator to minimize the possibility of misuse due to unclean air, wet air.
Dynabrade recommends the following: 10677 Air Line Filter-Regulator — Provides accurate air pressure regulation, two-stage filtration of
water contaminants.
• This tool should use filtered and regulated air, but does not require lubricated air. Lubricated air is not detrimental to tool life.
MAINTENANCE:
Daily (every 8 Hours):
• Inspect tool and accessories for damage or broken parts. Replace items as necessary to ensure proper operation and safety.
• Check air line pressure with a gage. (MAX. 90 PSIG or 6.2 Bar operating pressure at the air inlet of the tool.)
• 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 or once a week which ever comes first:
• Check free speed of tool without the abrasive accessory mounted. Measure RPM (speed) with tachometer and with an air pressure gage connected at
the air inlet of the tool. Maximum air pressure while the tool is running should read 90 PSIG (6.2 Bar). If a governed tool is operating at a higher speed
than the RPM marked on the tool housing, the tool must be serviced and corrected before use. A non-governed tool may exceed the RPM marked on
the tool by 10% when operated at free speed with no accessories.
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.
• 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, if not, reorder housing and replace. User is responsible for maintaining specification information.
• After maintenance is performed on tool 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).
• DO NOT carry tool by air hose or near the tool throttle lever.
• Store accessories in protective racks or compartments to
prevent damage.
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 part) and recycle or
discard per local, state and/or federal regulations as to not harm the environment.
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.
• 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.
DO NOT
Lubricate
