Whenever work is carried out on the rotary piston machine, it must be switched off and isolated from the electrical
mains supply. Failure to observe this point could result in injury or damage.
To ensure a long service life and optimum operating conditions, various steps should be taken. These include observ-
ance of the maintenance operations and intervals specified in this table.
Maintenance intervals
We recommend that you carry out maintenance
work on the rotary piston machine at the specified
intervals. The given operating hours assume that the
machine is being operated under average conditions.
The actual life of the equipment may vary depend-
ing on environmental conditions and operating data.
If you think this situation applies to you, please con-
tact
