Evacuator Valve
Open the evacuator valve once a week under ordinary
conditions - or daily when used in a dusty place - to get rid
of large particles of dust and dirt.

Cleaning Fuel Filter
To avoid personal injury or death:
A
Stop the engine and remove the key before
checking fuel lines and fuel filter.
A
Check the fuel lines periodically. The fuel lines
are subject to wear and aging. Fuel may leak
out onto the running engine, causing a fire.

Protect your hands when using kerosene to
clean components.
This job should not be done in the field, but in a clean
place.
1. Loosen and remove the filter bowl, and rinse the inside
with kerosene.
2. Take out the element and dip it in the kerosene to
rinse.
3. After cleaning, reassemble the fuel filter, keeping out
dust and dirt.
4. Bleed the fuel system.
(See "SERVICE AS REQUIRED" in "PERIODIC
SERVICE" section.)

When the fuel filter bowl has been removed, fuel stops
flowing from the fuel tank. If the fuel tank is almost full,
however, the fuel will flow back from the fuel return
pipe to the fuel filter. Before checking, make sure the
fuel tank is less than half-full.
