Installation of vibrating tools
It is recommended that a minimum length of 300
mm of flexible hose for compressed air is inserted
between a vibrating tool and the quick-action coup-
ling.
Air quality
• For optimum performance and maximum product
life we recommend the use of compressed air with
a dew point b2°C and +10°C. Installation
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 recommend that you install an
Atlas Copco oil-fog lubricator DIM, to be set
normally at 3–4 drops (50 mm
3
)/min for long cycle
running tools, or an Atlas Copco single-point
lubricator type Dosol for short cycle running tools.
For Dosol setting please see Air Line Accessories
in our main catalogue.
