1186 MM267 (6–94)
The care an LPG fuel tank receives has a direct
bearing on how long that tank can be used safely.
LPG fuel tanks must not be dropped or dragged
across any surface. To move LPG fuel tanks, use
a hand truck or roll the tank on its foot ring while it
is being held in a position slightly off vertical.
Whether the storage is inside or outside, fuel
tanks should not be stored in the vicinity of
combustible materials or high temperature
sources such as ovens and furnaces, since the
heat may raise the pressure of the fuel to a point
where the safety relief valves would function. Tank
care to insure that the tanks are stored in such a
way that if the safety relief valves do function,
they will relieve vapor, rather than liquid.
Valves on empty tanks must be closed during
storage and transportation.
Similar precautions should be taken in storing
machines fitted with LPG fuel tanks. The
machines may be stored or serviced inside
buildings, provided there are no leaks in the fuel
system and the tanks are not overfilled. While
machines are being repaired inside a building, the
shut-off valve on the tank must be closed, except
when the engine must be operated.
Changing the tanks is a chance for the machine
operator to carefully observe the tank, fittings, and
the fuel lines and fittings. If abnormal wear is
detected, the operator should notify the
appropriate personnel for appropriate action.
TO CHANGE AN LPG FUEL TANK
1. Park the machine in a designated safe area.
FOR SAFETY: When Servicing Machine, Keep
Flames And Sparks Away From Fuel System
Service Area. Keep Area Well Ventilated.
2. Close the tank service valve.
3. Operate the engine until it stops from lack of
fuel.
FOR SAFETY: Before Leaving Or Servicing
Machine; Stop On Level Surface, Set Parking
Brake, And Turn Off Machine.
4. Put on gloves and remove the
quick-disconnect tank coupling.
5. Inspect the LPG fuel lines for wear or
damage.
6. Remove the empty LPG fuel tank from the
machine.
7. Check the tank for damage or wear.
8. Store the tank in a designated safe area.
9. Select a filled LPG fuel tank and inspect it
for damage or leaks.
NOTE: Make sure the LPG fuel tank matches the
fuel system (vapor tank with vapor system).
10. Carefully place the LPG tank in the machine
so that the tank centering pin enters the
aligning hole in the tank collar.
NOTE: If the pin cannot be engaged, make sure
you have the correct LPG fuel tank and then
adjust the pin locator in or out.
11. Fasten the tank hold-down clamp to lock the
tank in position.
12. Connect the LPG fuel line to the tank
service coupling. Make sure the service
coupling is clean and free of damage. Also
make sure it matches the machine service
coupling.
13. Open the tank service valve slowly and
check for leaks. If an LPG leak is found,
close the service valve immediately and
notify the appropriate personnel.
14. If no leaks are found, the engine is ready to
start.
