To bleed the fuel system:
1. Loosen the air bleed vent screw (1) two full turns
by hand on the fuel filter base.
2. Operate the fuel supply pump primer lever (2), or
the primer button on the fuel filter base (if
equipped), until fuel flows out of the bleed vent
screw.
3. Tighten the bleed vent screw securely. Continue
operating the primer until the pumping action is
no longer felt.
4. Start the engine and check for leaks.
If the engine does not start, repeat steps 1 to 3.

Adjustments and service
procedures
5.5.1
Battery care
If the battery is still dry, it must be activated as
described in chapter “Activating a dry-charged
battery”.
The battery must be in operation within 2 months
from being activated; if not, it needs to be recharged
first.
5.5.1.1
Electrolyte
Electrolyte in batteries is a sulphuric acid solution in
distilled water.
The solution must be made up before being
introduced into the battery.
5.5.1.2
Activating a dry-charged battery
– Take out the battery.
– Battery and electrolyte must be at equal
temperature above 10°C.
– Remove cover and/or plug from each cell.
– Fill each cell with electrolyte until the level
reaches 10 to 15 mm above the plates, or to the
level marked on the battery.
– Rock the battery a few times so that possible air
bubbles can escape; wait 10 minutes and check the
level in each cell once more; if required, add
electrolyte.
– Refit plugs and/or cover.
– Place the battery in the generator set.
5.5.1.3
Recharging a battery
Before and after charging a battery, always check the
electrolyte level in each cell; if required, top up with
distilled water only. When charging batteries, each
cell must be open, i.e. plugs and/or cover removed.
Apply with preference the slow charging method and
adjust the charge current according to the following
rule of thumb: battery capacity in Ah divided by 20
gives safe charging current in Amp.
