SAFETY INSTRUCTIONS (Cont.)
• Before mounting an accessory, visually inspect for defects. Do not use defective accessories.
• Use only accessories of the correct mandrel size for the collet.
• Follow tool specifications before choosing size and type of accessory.
• Only use recommended fittings and air line sizes. Air supply hoses and air hose assemblies must have a minimum working pressure rating of 150 PSIG
(10 Bars, g) or 150 percent of the maximum pressure produced in the system, whichever is higher. (See tool Machine Specifications table.)
• If a mounted wheel is broken, a careful investigation should be made by the user to determine and correct the cause.
OPERATING INSTRUCTIONS
Warning: Always wear personal protection equipment. Operator of tool is responsible for following: accepted eye, face, respiratory, hearing and body protection.
Adjacent personnel must be protected from potential injury.
Warning: Be sure that any loose clothing, hair and all jewelry is properly restrained. Keep hand and clothing away from working end of the air tool.
Warning: Do Not use cut-off wheels or router bits.
Caution: Hand, wrist and arm injury may result from repetitive work, motion and overexposure to vibration.
• BEFORE MOUNTING AN ACCESSORY, after all tool repairs and whenever a pencil 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, or operating
improperly, the tool must be serviced and corrected before use.
Caution: Tool RPM must never exceed abrasive/accessory RPM rating. Check accessory manufacturer for details on maximum operating speed or special
mounting instructions.
• Make sure tool is off and connect power source. Do not expose air tool to inlet pressure above 90 PSIG or (6.2 Bars).
• Turn off inlet valve in case of an interruption of the energy supply.
• This tool should use filtered and regulated air, but does not require lubricated air. Lubricated air is not detrimental to tool life.
Caution: After installing the accessory, before testing or use and/or after assembling tool, the pencil grinder must be started at a reduced speed to check
for good balance. Make sure no one is in the unguarded plane of the wheel. Gradually increase tool speed. DO NOT USE if tool vibration is
excessive. Correct cause, and retest to insure safe operation. Run tool for 1 minute of operating speed in a protected area.
• Make sure that work area is uncluttered, and visitors are at a safe range from the tools and debris.
• 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.
Warning: Sanding certain materials can create explosive dust. It is the employers responsibility to notify the user of acceptable dust levels. Reduce the risk
by using dust collection systems and personal protective equipment.
• Tools exhaust may contain bearing grease, and other materials. Direct exhaust away from operator.
• Use hearing protection when working with materials that produce high process noise levels. Permanent hearing loss can result from high sound levels.
• Do not set the tool down until the on/off valve is OFF and the tool has stopped turning.
• Always use dust extraction or suppression systems and personal protective equipment which are suitable for the materials being processed.
Report to your supervisor any condition of the tool, accessories, or operation you consider unsafe.

MANDREL ACCESSORY MOUNTING INSTRUCTIONS
With Power Source Disconnected from the Tool, Mount Recommended Accessory
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. Air pressure easily forces dirt or water contained in the air supply into motor bearings causing early failure. Dirt and water often score the inner
workings of the tool 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 maintenance during the use of this tool.
Lifetime Warranty
All Dynabrade portable pneumatic power tools are rigorously inspected and performance tested in our factory before shipping to our customers. If a Dynabrade tool develops
a performance problem and an inherent defect is found during normal use and service, Dynabrade will warrant this tool against defects in workmanship and materials for
the lifetime of the tool. Upon examination and review at our factory, Dynabrade shall confirm that the tool qualifies for warranty status, and will repair or replace the tool at
no charge to the customer. Normally wearable parts and products are NOT covered under this warranty. Uncovered items include bearings, contact wheels, rotor blades,
regulators, valve stems, levers, shrouds, guards, O-rings, seals, gaskets and other wearable parts. Dynabrade’s warranty policy is contingent upon proper use of our tools
in accordance with factory recommendations, instructions and safety practices. It shall not apply to equipment that has been subjected to misuse, negligence, accident or
tampering in any way so as to affect its normal performance. To activate lifetime warranty, customer must register each tool at www.dynabrade.com. Dynabrade will not
honor lifetime warranty on unregistered tools. A one-year warranty will be honored on all unregistered portable pneumatic power tools. Lifetime warranty applies only to
portable pneumatic tools manufactured by Dynabrade, Inc. in the USA. Lifetime warranty applies only to the original tool owner; warranty is non-transferable.

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 at each work station, if the supply
pressure is high.
•
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.
