1. LPG fueling and replace
After the fuel in cylinder is run out, replace it. First close the outlet stop valve, disconnect quick
coupling, put the quick connectors on the cylinder outlet valve with dust cover, remove the
cylinder and fuel it at gas station. During fueling, lay down the cylinder, put the inlet meter valve
on top(liquid level indicating meter to horizontal line at 60°degree angle at this time), and then
screw off the dust cover on the inflation valve, insert inflation plug, open the inlet limit valve to
fuel. When the LPG fuel to 80% of the cylinder volume, take out the inflation plug( when fuel to
80% of rated volume, its limit device will shut down automatically). After finishing fueling, take
out the plug, screw on the dust cover of inflation valve, and tighten the inlet limit valve.
After install the cylinder in certain angle(liquid level indicating meter to horizontal line at
60°degree angle), connect pipeline with quick connector, turn on the outlet
stop valve switch to
check if there is air leakage, otherwise eliminate it. Then start the truck. Close it after truck use.
