IMPORTANT SAFETY INSTRUCTIONS
To reduce the risks associated with the use of abrasive products, disc pads, tool breakup, sharp
edges, hazardous pressure, rupture, vibration and noise:
•Read, understand and follow the safety information contained in these instructions prior to using
this tool. Keep these instructions for further reference.
• Only properly trained personnel should service this tool. Any other service will void warranty.
• Practice safety requirements - work alert, have proper attire, and do not operate tools under the
influence of alcohol or drugs.
• Operators and nearby personnel must always wear protection for eyes, ears, and respiratory
protection when in the work area or while operating this product. Follow your employer’s safety
policy for PPE’s and/or ANSI Z87.1 or local/national standards for eye wear and other personal
protective equipment requirements.
• Never exceed marked maximum input pressure (90psi / .62Mpa / 6.2Bars).
• Proper eye protection must be worn at all times.
• Tool shall not be operated in the presence of bystanders.
• If you notice any abnormal noise or vibration when operating the product, immediately discontinue
its use and inspect for worn or damaged components (mounting hardware, abrasive product, etc).
Correct or replace the problem component. If the problem persists, return the tool to PTA Canada
for repair or replacement. Please refer to warranty instructions.
• Never operate this tool without all safety features in place and in proper working order.
• Do not remove or disable safety feature of on-off control device.
• Make sure the tool is disconnected from its air source before servicing, inspecting, maintaining,
cleaning, and before changing abrasive product.
• Prior to use, inspect abrasive product, disc pad, and other accessories for possible damage. If
damaged, replace with new abrasive product and accessories available from PTA Canada.

• Use only with mounting hardware recommended by PTA Canada; check with PTA Canada for
mounting hardware requirements.
• Always ensure that shaft diameters match internal diameters of the collet inserts.
• Maximum operating speed of abrasive products or accessories must be reduced whenever the
exposed length of shaft (overhang) is longer than corresponding PTA Canada approved products.
• Use only with abrasive products not requiring guards according to local, state and federal
regulations.

RISKS PREVENTION
Vibration • If any physical discomfort is experienced, work should be stopped
promptly to seek medical attention. Injury may result from repetitive work,
motion and exposure to excessive vibration.
Loud Noise • Always wear protection for eyes, ears, and respiratory protection while
operating this product. Follow your employer’s safety policy for PPE’s and/
or ANSI Z87.1 or local/national standards for eyewear and other personal
protective equipment requirements..
Fire or Explosion • Do not operate the tool in explosive atmospheres, such as in the
presence of ammable liquids, gases, or dust. The abrasives are able
to create sparks when working material, resulting in the ignition of the
ammable dust or fumes.
Dust Ingestions or
Eye/Skin Exposure
• Use appropriate respiratory and skin protection, or local exhaust as
stated in the MSDS of the material being worked on.
Hazardous Voltage • Do not allow this tool to come into contact with electrical power sources
as the tool is not insulated against electrical shock.
Skin Abrasion/Burns/
Cuts/Entrapment
• Keep hands, hair, and clothing away from the rotating part of the tool.
• Wear suitable protective gloves while operating tool.
• Do not touch the rotating parts during operation for any reason.
• Do not force tool or use excessive force when using tool.
Fly O󰀨 of Abrasive
Product or Parts
• Use care in attaching abrasive product, disc pad, and mounting hardware;
following the instructions to ensure that they are securely attached to the
tool before use.
Hazardous Pressure
Rupture
• Be aware that incorrectly installed hoses and ttings might unexpectedly
come loose at any time and create a whipping/impact hazard.

PRODUCT CONFIGURATION / SPECIFICATIONS
*The noise levels stated in the table are from laboratory testing and are not su󰀩cient risk evaluation. Values
measured in a particular work place may be di󰀨erent from the declared values. The actual exposure values and
amount of risk or harm experience by an individual is unique to each situation depending on the surrounding situation.
OPERATING INSTRUCTIONS
Before each use:
• Always operate, inspect and maintain tool in accordance with all regulations that may apply to
handheld, hand operated pneumatic tools
• Use a clean lubricated air supply that will give a measured air pressure at the tool of 6.2 bar (90
psig) when the tool is running with the lever fully depressed. Tool will operate at less than maximum
pressure - performance will be reduced. It is recommended to use an approved 10 mm (3/8 in) x 8
m (25 ft) maximum length airline.
Beginning of each use:
• Lubricate tool by putting 2 to 3 drops of suitable pneumatic motor lubricating oil into the hose end
(inlet) of the tool. Connect the tool to the air line and run slowly for a few seconds. Disconnect to
safely install desired abrasive. If tool is used frequently, oil daily or when the tool begins to slow or
lose power.
• Select desired abrasive and install with wrenches provided. Ensure abrasive product is rated for
the tools rpm rating. Use the wrench to secure the collet body while turning the collet nut clockwise.
Ensure abrasive is mounted properly before use - an inadequately inserted shank could bend or
break causing damage to the tool and work piece and possible injury to the operator or bystanders.
• Depress switch to operate tool.
SAFETY PRECAUTIONS
• Read all instructions before using this tool. All operators must be fully trained in its use and aware
of safety rules.
• The tool RPM should be checked on a regular basis (at shift change).
• Always wear required safety equipment when using this tool.
• Always remove the air supply to the sander before tting, adjusting or removing the abrasive or
disc pad.
• Always adopt a rm footing and grip and be aware of torque reaction developed by the sander.
• Use only PTA Canada approved spare parts.
• Always ensure the material being worked is rmly xed to avoid movement.
• Check hose and ttings regularly for wear. Do not carry the tool by its hose.
• Dust can be highly combustible. Vacuum dust collection bag should be cleaned or replaced as
needed.
• If tool is serviced or rebuilt, check to ensure the maximum tool RPM is not exceeded and that there
is not excessive tool vibration.
• Do not exceed maximum recommended air pressure. Use safety equipment as recommended.
• Prior to installing any shaft mounted abrasive or sanding or grinding accessory, always check that
its marked maximum operating speed is equal or higher than the rated speed of this tool.
• The tool is not electrically insulated. Avoid use near live electricity, gas pipes, and/or water pipes.
• This tool is not protected against hazards inherent in cutting operations, and no such cutting
products should ever be attached.
• Take care to avoid entanglement with the moving parts of the tool with clothing, ties, hair, cleaning
rags or loose hanging objects. If entangled, stop air supply immediately to avoid contact with
moving tool parts.
• Keep hands clear of the spinning pad or spindle during use.
• If the tool appears to malfunction, remove from use immediately and arrange for service and
repair.
• Immediately release the start handle in the event of any disruption of pressure; do not attempt to
re-start until the disruption has been corrected.
• When tool is not in use, store in a clean, dry environment free of debris.
