WARNING Dust hazard
Some dust, fumes or other airborne material created by power sanding, saw-
ing, grinding, drilling and other constructions activities contains chemicals
known to the State of California to cause cancer and birth defects or other re-
productive harm. Some examples of such chemicals are:
Crystalline silica and cement and other masonry products.
Arsenic and chromium from chemically-treated rubber.
Lead from lead based paints.
►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 specially designed to filter out microscopic particles
►Avoid inhaling dust or handling debris from the work process which can
be harmful to your health
►Use dust extraction e.g. spot suction equipment and wear respiratory pro-
tective equipment when working with materials which produce airborne
particles
►Potentially explosive atmospheres can be caused by dust and fumes re-
sulting from sanding or grinding. Always use dust extraction or suppres-
sion systems which are suitable for the material being processed
WARNING Projectiles
During power sanding, sawing, grinding, drilling and other construction ac-
tivities sparks, chips, wheel fragments or other particles may turn into pro-
jectiles and cause bodily injury by hitting the operator or other persons.
Even small projectiles can injure your eyes and cause blindness.

Installation
Installation of vibrating tools
It is recommended that a minimum length of 300 mm of flexible hose for com-
pressed air is inserted between a vibrating tool and the quick-action coupling.
Air quality
• For optimum performance and maximum product life we recommend the
use of compressed air with a dew point between +2°C and +10°C. Installa-
tion of an Atlas Copco refrigeration-type air dryer is recommended.
• Use a separate air filter of type Atlas Copco FIL, removes solid particles
larger than 15 microns and more than 90 % of liquid water, installed as
close as possible to the product and prior to any other air preparation unit
like REG or DIM (please see Air Line Accessories in our main catalogue).
Blow out the hose before connecting.
Lubricated models:
• The compressed air must contain a small quantity of oil. We strongly rec-
ommend that you install an Atlas Copco oil-fog lubricator DIM, to be set
normally at 3–4 drops (50mm3)/min for long cycle running tools, or an At-
las Copco single-point lubricator type Dosol for short cycle running tools.
For Dosol setting please see Air Line Accessories in our main catalogue.
Compressed air connection
WARNING Air under pressure can cause serious injury
►Always shut off air supply, drain hose of air pressure and disconnect tool
