Maintenance
A type WEH maintenance unit, consisting of filter, water separator,
and oiler, must be connected upstream of the power chuck. The
air enriched with oil supplies all sliding parts of the cylinder
chamber with an oil film. The oil level of the oil tank must be
checked daily, and oil must be added if necessary. If the oil
consumption is too low, i.e. if the oil level does not visibly drop
over a period of 2 to 3 days, the oil adjustment screw must be
opened slightly. Depending on the accumulation of condensation,
the condensation drain screw must be opened occasionally.
