California Proposition 65
WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals
known [to the State of California] 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, and
 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.
Precautions on Use (Make sure to follow the instructions given)
Before using your tool, to avoid personal injury always take the basic precautions explained in later sections.

Air pressure used
Use the tool with air pressure at 0.6 MPa. If the pressure is too low, the tool cannot demonstrate the required
performance. If it is too high, it could damage parts of the tool. Use an Air Regulator (③) to adjust the pressure to the
appropriate level.
Air line
Use a Connecting Hose (⑤) with an internal diameter of 9.5 mm (3/8”) between the Compressor (①) and the tool (⑧).
Compressed air exits the Compressor and cools and moisture condenses. Some moisture could condense inside the
Connecting Hose and get inside the tool, causing a malfunction. Install the Air Filter (②) and Lubricator (④) between
the Compressor and the tool.
Machine oil
Install a Lubricator between the Compressor and the tool, and be sure to use machine oil (ISO VG-10).
Failure to do so could cause damage to the tool. Also, if lubricating oil with high viscosity is used, it could cause
performance degradation.
Refueling
Each day before starting work detach the Connecting Hose and refill a few drops of machine oil (ISO VG-10) (⑥) from
the Coupler (⑦) to the tool.
After refueling, connect the Connecting Hose and perform idle operation for a few seconds to allow the oil to blend in
the entire tool.
