Air discharge from fuel line
Air discharge from the fuel line is required
only when starting the engine under following
conditions:
a) Starting the brand-new engine for the
first time.
b) Restarting the engine after the engine
has stopped due to fuel shortage.
Air discharging procedure
(See Fig. 4 -A, 5 -A)
Open the fuel valve.
Set the speed control lever to the “START”
position and pull the recoil starter handle
slowly 2 or 3 times. Air will be discharged
from the fuel line automatically.
- OPEN
- START
■ If the fuel tank is refilled before it gets
empty, air discharge is unnecessary.
■ If the high-pressure pipe is disassembled
for the purpose of serving/ maintaining
injection nozzle, discharge air from the high-
pressure pipe by the following procedure:
Set the speed control level to the “START”
position and detach the cap nut of the high-
pressure pipe on the side of the nozzle. Pull
the recoil starter handle slowly until fuel is
sufficiently injected.
CAUTION
■ When discharging air from the fuel line,
be sure to fill fuel tank with enough fuel (at
least 2 liters).
WARNING
■ Wipe off any split fuel before starting the
engine, otherwise fire accident may occur.

2. CHECK PRIMING WATER
