Operating instructions

In your own interest, always strictly
!
observe all relevant
instructions.
Do not operate the generator in
excess of the limitations mentioned
in the Technical Specifications.
Local rules concerning the setting
up of low voltage power installations
(below 1000 V) must be respected
when connecting site distribution
panels, switch gear or loads to the
generator.
At each start-up and at any time a
new load is connected, the earthing
and protections (GB trip and earth
leakage relay) of the generator must
be verified. Earthing must be done
either by the earthing rod or, if
available, by an existing, suitable
earthing installation. The protective
system against excessive contact
voltage is not effective unless a
suitable earthing is made.

Before starting

– With the generator standing level, check the
engine oil level and top up if necessary. The oil
safety
level must be near to, but not exceed the high mark
on the engine oil level dipstick.
– Check the coolant level in the expansion tank of
the engine cooling system. The coolant level must
be near to the FULL mark. Add coolant if
necessary.
– Drain any water and sediment from the fuel pre-
filter. Check the fuel level and top up if necessary.
It is recommended to fill the tank after the day's
operation to prevent water vapor in a nearly empty
tank from condensing.
– Drain leaking fluid from the frame.
– Check the vacuum indicator of the air filter. If the
red part shows completely, replace the filter
element.
– Press the dust evacuator of the air filter to remove
dust.
– Check the generator for leakage, tightness of wire
terminals, etc. Correct if necessary.
– Check that circuit breaker Q1 is switched off.
– Check that fuse F10 has not tripped and that the
emergency stop is in the OUT position.
– Check that the load is switched off.
– Check that the earth fault protection (N13) has not
tripped (reset if necessary).
