5.5 Pneumatic Installation
This pneumatic machine may be operated with lubricated air. The best performance is
achieved by adding 1 - 2 drops oil per 1 m

hose I.D. should be installed in order to avoid a loss of power.
Note: the maximum length of hose is 5-meters.
The air-supply for the drill needs to be filtered (see chapter 5.6).
Do not use any Teflon tape on the threads of the pipe.

reduces the power output of the drill.
The maintenance unit, the valves and the silencers have to be
selected according to the air consumption of the machine. Install
components, which have a measurement that will limit the pressure
drop – when measured from the maintenance unit to the machine –
to less than 0.5 bar (7.25 PSI).
