• Do not use the tool in the presence of any flammable liquids or gases.
• Keep the hose away from heat, oil, and sharp edges. Check the hose for signs of damage, and ensure that all connections are secure. Failure to comply could
lead to serious injury or loss of life.
• Keep hands and other parts of the body away from the work area when connecting the air supply. Failure to comply could lead to serious injury or loss of life.
OPERATING INSTRUCTIONS
Loading and operation
1. Disconnect the tool from the air hose.
2. Use the two wrenches to loosen the chuck.
3. Insert a suitable grinding accessory into the chuck and firmly retighten the chuck to lock the grinding accessory in place using the wrenches.
4. Plug in the compressor, turn it on, set the pressure regulator to 90psi, attach one end of the air hose to the compressor and the other end to the tool. Use
plumber's tape to avoid air leaks.
5. With a firm grip on the tool lightly press the trigger and apply the accessory to the workpiece, slowly and steadily moving the tool until the desired finish on
the workpiece has been achieved.
Proper use
• Hold the tool firmly with both hands. Always point abrasive material away from you while operating the tool.
• Do not apply additional or excessive force to the tool when grinding.
• Do not allow the tool to run continuously for an extended period of time. Doing so will shorten the life of the tool.
• Verify that the air supply is clean and air pressure does not exceed 90 psi (6.3 bar) while operating the tool. If the air pressure is too high or the air is unclean,
it will shorten the life of the tool. Failure to comply could result in serious injury or loss of life.
MAINTENANCE
• The tool must be inspected periodically and worn or broken parts must be replaced in order to keep the unit operating safely and efficiently.
• Disconnect the tool from the air supply before changing accessories, servicing, or performing maintenance.
• Only use the tool after replacing or repairing the damaged parts or accessories.
• Use only replacement parts and accessories that are compatible and suitable for use with the tool.
• Repairs must be performed by a qualified service technician.

Lubrication
• Lubrication: If the air tool and the compressor are not equipped with an in-line lubrication system, place up to 6 drops of pneumatic tool oil into the air inlet
before each work day or after every 2 hours of continuous use, depending on the characteristics of the workpiece.
• Inspect and replace worn or damaged O-rings, seals, etc. Tighten all screws and caps frequently in order to help prevent personal injury.
• Loss of power or problematic operation may occur due to the following:
- Excessive drain in the air line.
- Moisture or blockage in the air pipe.
- Incorrect size or type of hose connector. Check the air supply and follow the instructions.
- Dirt accumulation in parts of the unit may also reduce performance.
• Ensure that no part is loose or missing and that no part is jammed.
• When the tool is not in use, disconnect it from the air supply, clean it and afterwards store it in a safe and dry place not accessible to children.
• When temperatures are below freezing, keep the tool as warm as possible using any safe, convenient method.
STORAGE
• Apply an ample amount of lubrication before storing the tool.
• Run the tool for approximately 30 seconds after lubricating, in order to ensure that the lubricant is uniformly distributed throughout the tool.
• Store the tool in a clean and dry place.
