■ Fuel Tank - Drain Water
Drain water from the fuel tank.
Fuel System - Bleed Air
While feeding fuel with the priming pump, bleed air
from the location closest to the fuel tank, that is, in
the order of the water separator, fuel filter, and fuel
injection pump.
• Devices and equipment outside the
scope of our supply are included in the
facility.
For the details, refer to such a
document as the specifications sheet
prepared by the generator
manufacturer.
• For the devices and equipment outside
the scope of our supply, refer the
corresponding manual of the generator
and the supplier's operation manual.
When draining water from the fuel
tank, always use a container which is
suitable for the water quantity.
* Otherwise, the drained water will overflow from
the container, which may flow outside of the
facility.
* The water drained into the container is
contaminated with fuel. Discard the water in
accordance with the local laws and regulations
as well as the manufacturer's SDS.
Drain water properly from the fuel
tank.
* If water, dust, or other foreign particles are left,
they may mix with fuel and cause low output
power or damage to the devices in the fuel
system.
Bleed air sufficiently from the fuel
system.
* Otherwise, starting failure may occur.
After bleeding, tighten the priming
pump firmly.
* If the tightening torque is too weak, fuel leak
may occur.
* If the tightening torque is too strong, the priming
pump may be damaged.
