5.5 Checking the oil level
This section outlines the procedure for checking the oil level in
the compressor.
The level in the oil tank is a key factor in the operational safety
of the unit. Due diligence should be exercised in conducting the
following checks at the specified times. Otherwise we cannot
accept liability in the event of damage.
Follow the safety instructions for venting the unit (see
Chap. 5.3)!
Step Instructions

from being restarted.
2
Wait until the unit has been switched off for at least
three minutes.

Optimum oil level: Oil level should ideally be in the

If necessary, refill to the maximum mark with oil of
the same kind.
