1. Mechanical checks:
At monthly intervals and at every commissioning, check the following:

Abnormal operating noises

Damage / functional limitations to the protective hood

The air intake and outlet openings must be clear

Check the sockets for mechanical damage and thermal overloads

Check the circuit breakers for damage to seals, and measuring instruments for
mechanical integrity

Designations / signs on display and operating instruments

Operating Manual

Oil level in transmission unit
2. Electrical checks:
Once a month, or at each commissioning, check the following:

the earthing connection for perfect condition
Every 500 operating hours but no less than once per year, check the following:

NOTES ON ACCESS TO THE SWITCH
The magnetic cut-out can be accessed for three purposes:
- if a device or a series of devices has been connected and they need higher current
than the switch's rated current
- if a short circuit occurs
In the first case, it is sufficient to reduce the load and then restart the generator,
whereas in the second case, the cause of the short-circuit must be found and
rectified.
