7.1

Ensure operational safety

Regular maintenance work must be carried out in order to ensure operational safety.
The cleaning and oil change intervals strongly depend on how the machine is loaded (operating time, oper-
ating conditions, etc.) and the type of oil used. Depending on the pollution of the sucked in medium and the
environmental conditions, the cleaning intervals of the intake filters and the gas ballast valve can be shorter.
Extreme temperatures or pollutions can reduce the lifetime of the oil to 5,000 operating hours. The specified
interval of up to 20,000 operating hours only applies to types of oil delivered or approved by Elmo Rietschle.
For all works, observe the safety instructions described in chapter 2 "Safety".
The whole plant should always be kept in a clean condition.
Danger of death from touching live parts!
Touching of live parts cause serious injuries or death.
Ø Before starting any maintenance work, disconnect the machine by actuation
of the main switch or disconnection of the plug and secure it against acciden-
tal switching.
Ø Works on the electrical installation must be carried out by an electrician only.
Ø Repair works are only allowed to be done by authorised specialists.
Risk of injury due to hot surfaces!
When the machine is at operating temperature the surface temperatures on the
components may rise to above 70 °C. This can cause burns.
Ø Wait for the machine to cool down.
Ø Before maintenance and repair works allow the machine to cool down.
Ø Wear suitable protective clothes, if necessary.
Risk of injury due to missing safety devices!
Missing safety devices can cause injuries.
Ø Safety devices as well as safety guards on motor fans and ventilators may not
be removed.
