USE AND CARE OF LP TANKS
If an LP tank is damaged or leaking, it should be immediately removed to a designated safe area and the proper
personnel should be notified. Do not attempt to make repairs to the cylinder regardless of its condition. Repairs
must be made by qualified personnel.
The care an LP tank receives has a direct bearing on how long the tank can be used safely. LP tanks must not be
dropped, dragged, or slid across any surface. To move the LP tank, use a hand truck or roll the tank on its foot ring
while it is being held in a position slightly off the vertical.
CHANGING LP TANKS
Refueling machines with LP tanks is an important process. Refueling is accomplished by replacing the empty LP
tank with a full tank.
The tank changing operation presents an opportunity for the machine operator to carefully inspect the tank, tank
fittings, the fuel lines and fuel line fittings. If abnormal wear is detected, the operator should report these findings to
the appropriate personnel for immediate action.
1.
Park the machine in a designated safe area and set the parking brake.
2.
Close the tank valve.
3.
Remove the quick-disconnect coupling from the tank valve.
4.
Inspect the machine’s fuel lines and the quick-disconnect coupling for damage or abnormal wear.
5.
Remove the empty tank from the holding device.
6.
Inspect the tank and tank fittings for damage or abnormal wear. Handle the tank carefully. It must not be
dropped or mishandled.
7.
Store the LP tank in a designated safe area.
8.
Select a full LP tank and observe for damage or leaks.
9.
Carefully install the full tank in the machine so the tank-centering pin enters the aligning hole in the tank
collar. This assures that the tank is positioned properly and allows for proper operation of the safety relief
valve, liquid level gauge, and service valves.
10. Fasten the tank-retaining bracket so the tank is locked into position.
11. Reconnect the fuel line to the tank-servicing coupling.
12. Open the service valve slowly and check for leaks. If a leak is found, close the valve immediately and notify
the appropriate personnel.
13. If no leaks are detected, the engine is ready to start. Do not start the engine unless the operator is in
position with the directional control pedal in the neutral position.
STORING LP FUEL TANKS
Whether the storage is inside or outside, the LP tanks should not be in the vicinity of combustible materials or high
temperature sources such as ovens or furnaces. This may cause the heat to raise the pressure of the fuel to a point
where the safety relief valves would begin operation. Care should be taken to ensure that the cylinders are stored
in such a manner that if the safety relief valves are triggered, the vapor will be relieved rather than any liquid.
Valves on empty tanks must be closed during storage and transportation.
