Fuel level check and refueling
1. Check to see that the fuel level is above the lower limit
of the fuel level gauge.
2. If the fuel is too low, add fuel to the upper limit. Do not
overfill.
B
Checking the fuel pipes
To avoid personal injury or death:
A
Stop the engine before checking or
replacing the fuel pipes. Broken fuel
pipes can cause fires.
Check the fuel pipes every 50 hours of operation. When if;
1. If the clamp band is loose, apply oil to the screw of the
band, and tighten the band securely.
2. If the fuel pipes, made of rubber, become worn out,
replace them and clamp bands every year.
3. If the fuel pipes and clamp bands are found worn or
damaged before one year passes, replace or repair
them at once.
A
When the fuel pipes are not installed, plug them at
both ends with clean cloth or paper to prevent dirt from
entering. Dirt in the pipes can cause fuel injector
malfunction.
A
For the locations of fuel pipes, see “Fuel system
diagrams” in “FUEL SYSTEM AND DIAGRAMS”
section.

LPG leakage check
[WG1605-L-E3 / WG1605-GL-E3 / WG1605-LN-E3 /
WG1903-L-E3 / WG1903-GL-E3 / WG1903-LN-E3 /

WG3800-L-E3 / WG3800-GL-E3 / WG3800-LN-E3]
To avoid personal injury or death:
A
Never test for gas leaks with a flame.
Turn on the gas at low idling rpm and use a soap solution
or equivalent to check all connections for leaks between
the fuel tank and D-EPR.
Bubbles will indicate a loose connection.
