(3) Inspecting the Insect Net
If the net is clogged, loosen the knob bolts to

(4) Inspecting the Fuel System

Fuel tank
Check if the tank contains enough diesel oil. If not,
add diesel oil.
(Tank capacity: Approx. 20 L)
Drain water from the tank from the fuel filler port
or fuel filter every 100 hours.
Add fuel before the fuel tank becomes empty and
should the fuel tank become empty, immediately add
fuel and bleed air.

Bleeding air
[1] Fill the fuel tank with diesel oil.
[2] Loosen fuel filter screw A and bleed air trapped
between the fuel tank and fuel filter.
[3] When only fuel starts to come out from the screw,
tighten screw A.
[4] Next, loosen screw B, bleed air trapped between
the fuel filter and solenoid pump in the same
manner, and tighten screw B.
[5]
Turn the key switch to “ON.” Operate the solenoid
pump for approx. 10 seconds in this condition to
bleed air trapped between the solenoid pump and
engine.
Caution

When bleeding air, put clothes underneath and
wipe off any spilled fuel.

Stop the engine during refueling.

Fuel filter
Clean the fuel filter every 100 hours or so of
operation, and replace the element every 400
hours.
The cleaning method is as follows:
[1] Close the fuel filter cock.
[2] Remove the ring screw and take out the filter cup.
[3] Rinse the element in diesel oil. Also clean the inside
of the filter cup with diesel oil.
[4] After the cleaning, assemble the filter cup correctly
as before by paying attention not to let dust or dirt
attach to the element.
