Warning: Air tools are not intended for use in explosive atmospheres and are not insulated for contact with electric power sources.
Warning: Always work with firm footing, good posture and proper lighting.
Warning: Drilling certain materials can create explosive dust. It is the employer's responsibility to notify the user of acceptable dust levels.
Caution: If the drill bit binds, the drill will suddenly react in the opposite direction of the rotation of the bit. The operator should prepare for a sudden reaction by holding the tool securely.
• Driving larger drill bits at the high speeds will increase the chance of reaction.
• Avoid drilling warped, wet, knotty, and pitchy materials if possible.
• When removing the drill bit from the tool avoid contact with the skin and use proper protective glove when grasping the drill bit. Drill bits may be hot after prolonged use.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris.
• A moving drill bit that snags or catches within the work piece may cause tool to stop unexpectedly or move erratically, which may cause injury.
• 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.
• 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 through the tool.
• Some materials contain chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

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. 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.

DRILL ACCESSORY MOUNTING INSTRUCTIONS
Warning: Disconnect air supply before removing inserted drill bit.
• Open chuck jaws wide enough to install drill bit. Be sure the bit shank and chuck jaws are clean. Dirt particles may prevent the drill bit from lining up properly.
• Insert the drill bit into the chuck. Center the drill bit in the chuck jaws and lift it about 1/16" off the bottom. Tighten the chuck jaws by hand to align the drill bit.
• Place the chuck key in each of the three holes in the chuck, turning it clockwise. Tighten securely.
Warning: Remove chuck key before turning the tool on.
• Connect air tool to air supply. Be careful NOT to depress trigger in the process. Do not expose air tool to inlet pressure above 90 PSIG or (6.2 Bars).
Caution: After installing the drill bit, before testing or use and/or after assembling tool, the Pistol Grip Drill 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.
• To remove the drill bit, insert the chuck key into the holes in the chuck and turn counterclockwise.
Bit Selection:
• Use sharp drill bits. Sharp drill bits are less likely to bind when drilling. Use the proper drill bit for the job.
• Check the information on the drill bit's packaging for proper usage. Do not use drill bits larger than the rated capacity of the drill.
Maintenance Instructions
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 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: 10681 Air Filter-Regulator-Lubricator (FRL) – Provides accurate air
pressure regulation and two stage filtration of water contaminant's.
•
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.
•
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.

Notice
All Dynabrade motors use the highest quality parts and materials 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.
