XIII. Precautions for use of the LPG forklift truck
The LPG fuel system mainly consists of a steel cylinder, filter, pressure reducing regulator, and mixer.
LPG enters the pressure reducing regulator from the steel cylinder through the combination valve
and high
-
pressure pipeline via the filter. After vaporization, LPG enters the mixer and mixes with air
in a certain proportion, then enters the engine cylinder for combustion and provides motive power
for the forklift. The GM 4.3L engine is provided with a pressure reducing regulator, mixer and other
LPG elements.
1. LPG filling and replacement
After the fuel in the steel cylinder is used up, it must be replaced. First, close the outlet stop valve,
loosen the pipe joint of the forklift truck, cover the outlet joint of the steel cylinder with a dust cap,
and remove the steel cylinder fixed on the truck, and fill it at the gas station. Place the steel cylinder
flat when refuelling, put the intake limit valve at the upper end (at that time, the included angle
between the liquid level gauge and the horizontal line should be 60°), unscrew the dust cover on the
filling valve, insert the filling valve, open the intake limit valve for filling, take out the filling plug
when LPG is refueled to 80% of the steel cylinder volume (when 80% of rated capacity is reached, the
limiting device will be automatically closed.) Pull out the filling plug, screw on the dust cover of the
filling valve, and tighten the intake limit valve when the filling stops.
Connect the forklift truck line after installing the steel cylinder at the correct angle (the included
angle between the liquid level gauge and the horizontal line should be about 60°), open the outlet
stop valve switch of the steel cylinder, and check whether there is a gas leak. If a gas leak is found,
the forklift truck can only be started after troubleshooting. Please close the valve on the steel
cylinder after using the forklift truck each time.
