➤ Close shut-off valves or otherwise isolate the machine from the gas network to ensure that no
compressed gas can flow back into the machine.
➤ Vent all pressurized components and enclosures.
➤ Check all machine gas hose connectors with a hand-held pressure gauge to ensure that all
read zero.
➤ Do not open or dismantle any valves.
When working on the drive system
Touching voltage carrying components can result in electric shocks, burns or death.
Touching the fan wheel, the coupling or the belt drive while the machine is switched on can result
in serious injury.
➤ Switch off and lock out the power supply disconnecting (isolating) device and check that no
voltage is present.

10.2 Linde regulations
➤ Linde regulations have priority and should be observed in all maintenance and service work.
10.3 Following the maintenance plan
10.3.1 Logging maintenance work
The maintenance intervals given are those recommended for KAESER original components
with average operating conditions.
➤ In adverse conditions, perform maintenance work at shorter intervals.
Adverse conditions are, e.g.:
■ high temperatures
■ much dust
■ high number of load changes
■ low load
➤ Adjust the maintenance intervals with regard to local installation and operating condi‐
tions.
➤ Document all maintenance and service work.
This enables the frequency of individual maintenance tasks and deviations from our recom‐
mendations to be determined.
Further information A prepared list is provided in chapter 10.20.
