Safety Information (continued)
AIR COMPRESSOR AND AIR TOOL SAFETY
1. Risk of Bursting. Do not adjust the regulator to result in output
pressure greater than the marked maximum pressure of this air
tool.
2. Ensure the hose is free of obstructions or snags. Entangled or
snarled hoses can cause loss of balance or footing and may
become damaged.
3. Never leave a tool unattended with the air hose attached.
4. Do not operate this tool if it does not contain a legible warning
label.
5. Do not continue to use a tool or hose that leaks air or does not
function properly.
6. Never direct a jet of compressed air toward people or animals.
7. Protect your lungs. Wear a face or dust mask if the operation is
dusty.
WARNING:
Some dust created by power sanding, sawing,
grinding, drilling and other construction activities contains
chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
Lead from lead based paint, crystalline silica from bricks
and cement and other masonry products, arsenic and
chromium from chemically-treated lumber.
Your risk from those 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 dust masks that
are specifically designed to filter out microscopic particles.

Important Warnings
Non-Rotary Percussive Power Tool
1. Accessory Hazards
2. Disconnect the non-rotary percussive power tool from the energy supply before changing the inserted tool or accessory.
3. Use only sizes and types of accessories and consumables that are recommended by the non-rotary percussive power tool
manufacturer; do not use other types of sizes of accessories and consumables.
4. For hammers, where appropriate, never use any chisel as hand struck tool. They are specifically designed and heat treated
for use only in non-rotary percussive power tools.
5. For hammers and breakers, where appropriate, never use blunt chisels, as they require excessive pressure and can break
from failure. Blunt tool-pieces can increase vibration and, therefore, sharp tools should always be used.
6. Avoid direct contact with the inserted tool during and after use, as it can be hot or sharp.
7. Never adjust the non rotary percussive tool, or change the accessory, backing pad, unless the air supply and air hose is
disconnected from the tool.
8. Always ensure that you are aware of the direction of the material chips and fragments being created by the tools operation
and ensure that the material chips and fragments are not directed to the operator or other persons in the area.
9. Eye protection, hearing protection, safety gloves and safety aprons must always we worn when operating a non rotary
percussive tool.
10. Only personnel trained in the correct methods to change accessories and accessory retainers should conduct these
operations.
11. Never operate the non rotary percussive tool unless the accessory retainer supplied by the non rotary percussive tool
manufacturer is correctly fitted.
