24.6.1 REPLACE FUEL FILTER ELEMENT
WARNING
‡ Engine is at high temperature immediately after the machine
has been operated. Wait for engine to cool down before
replacing the filter.
‡ Do not bring fire or sparks near the fuel.
Prepare a filter wrench and a container to catch the fuel.
1. Set the container to catch the fuel under the element cup.
2. Loosen ring 1, then remove element cup 2 and the element.
3. Wash element cup 2 in diesel oil or flushing oil, then install a
new element.
When replacing the element, replace the O-ring also.
4. Fill with fuel, then turn the starting switch to the START position
without depressing the accelerator pedal, and run the starting
motor for 15 – 20 seconds to crank the engine and bleed the air
from the system.
Do not run the starting motor continuously for more than 20
seconds. Wait for 2 minutes before turning the starting motor
running it again.
WARNING
When cranking the engine, confirm the safety around the en-
gine, as the engine may start.
Use the same method when the engine has run out of fuel. Crank
the engine 3 – 4 times for 15 – 20 seconds to bleed the air.
If the fuel tank is completely filled, the time taken to bleed the
air can be reduced.
It is also possible to bleed the air manually by operating lever 3
of the feed pump up and down.
5. After replacing the filter element, start up the engine and check
the filter seal face for possible oil leakage.
