Air Bleeding Procedures
IMPORTANT: Air in the fuel system may make the engine
hard to start or make it run irregularly. After
draining water and sediment from the fuel
filter, replacing the fuel filter, cleaning the
fuel solenoid pump strainer or running the
fuel tank dry, be sure to bleed the air from
the fuel system.
This machine is equipped with a fuel solenoid pump.
CAUTION: Fuel leaks may lead to fires.
1. Check that fuel cock (3) on the bottom of the fuel tank is
opened.
2. Turn the key switch ON and hold it in that position for ap-
prox. 3 minutes. Thereby, the electrical fuel pump oper-
ates, starting to bleed air.
3. While holding the key switch in the ON position, recip-
rocate fuel main filter priming pump (6). After air is bled
from the main filter, return priming pump (6) to the origi-
nal position.
4. After the main filter is filled with fuel, hold the key switch
in the ON position for 30 seconds.
5. Start the engine. Check the fuel supply system for fuel
leaks.
IMPORTANT: Even if air is not thoroughly bled, do not
hold the key switch in the ON position for
more than 5 minutes. In case air is not thor-
oughly bled, first return the key switch to
the OFF position. Then, after waiting for
more than 30 seconds, turn the key switch
ON again. Failure to do so may cause dam-
age to the electrical pump and/or discharg-
ing the batteries.
