EFORE STARTING
– With the generator standing level, check the engine oil
level and top up if necessary. The oil 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 water 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 recom-
mended to fill the tank after the day’s operation to prevent
waterdamp in a nearly empty tank from condensing.
– Check the vacuum indicator of the air filter. If the red part
shows completely, replace or clean the filter element.
– Press the vacuator valve of the air filter to remove dust.
– Check the generator for leakage, tightness of wire termi-
nals, etc. Correct if necessary.
– Check that the circuit breakers Q1, Q2 and Q3 are
switched off.
– Check that fuse F4 is not activated and that the emer-
gency stop is in the “OUT” position.
– Check that the load is switched off.
S
TARTING
– Insert the key in the starter switch and turn it to position I.
Wait until the preheat lamp goes out. Turn the key to
position and release it as soon as the engine fires. The
switch automatically returns to position I.
Do not keep the key in its utmost position for more
than 10 seconds (maximum 20 seconds in extre-
mely cold conditions). Wait two minutes between
each starting attempt.
If the engine fails to start and for starting in extre-
mely cold conditions, consult your local Atlas Copco
dealer.
– Check that the warning lamps on the control and indicator
panel are out.
– Run the engine for approximately 5 minutes to warm up.
– Check the voltmeter P4 (with voltmeter selector switch S4
in different positions) and the frequency meter P5.
– Switch on circuit breaker Q1, together with trip coil. If
power supply is done by means of X2 or X3, respectively
switch on Q2 or Q3 as well.
– Switch on the load and check ammeter P3, voltmeter P4
(voltmeter selector switch in different positions) and
frequency meter P5.
D
URING OPERATION
Following points should be carried out regularly:
– Check the engine gauges and the lamps for normal
readings.
Avoid to let the engine run out of fuel. If it happe-
ned, priming will speed up the starting.
– Check for leakage of oil, fuel or cooling water.
– Avoid long low-load periods. In this case, an output drop
and higher oil consumption of the engine could occur.
– Check, by means of the generator gauges, that the voltage
between the phases is identical and that the rated current
in the third phase (L3) is not exceeded.
– When single-phase loads are connected to the generator
output terminals, keep all loads well-balanced.
If the circuit breakers are activated during operation, switch
off the load and stop the generator. Check and, if necessary,
decrease the load.
The generator’s side doors may only remain opened for short
periods during operation, to carry out checks for example.
S
TOPPING
– Switch off the load.
– Switch off the circuit breakers.
– Let the engine run for about 5 minutes.
– Stop the engine by turning the starter key to position O.
Withdraw the key.
– Lock the side doors and the door of the indicators and
control panel to avoid unauthorized access.
