MAINTENANCE
1550 Gas/LPG/Diesel MM283 (9--01)
3--20
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 tank is a chance for the machine
operator to carefully check the tank, fittings, and
the fuel lines and fittings. If abnormal wear is
detected, the operator should report the findings
to the appropriate personnel.
TO CHANGE AN LPG FUEL TANK
1. Park the machine in a designated safe area.
Set the machine parking brake.
FOR SAFETY: Before Leaving Or
Servicing Machine; Stop On Level
Surface, Set Parking Brake, Turn Off
Machine And Remove Key.
2. Close the tank service valve.
3. Operate the engine until it stops from lack of
fuel.
WARNING: Engine Emits Toxic Gases.
Severe Respiratory Damage Or
Asphyxiation Can Result. Provide
Adequate Ventilation. Consult With Your
Regulatory Agency For Exposure
Limits. Keep Engine Properly Tuned.
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: The recommended tank size is a 33 lb (15
kg) tank. Larger tanks may impair the vision of the
machine operator.
NOTE: Make sure the LPG fuel tank matches the
fuel system (liquid tank with liquid 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 mounting bracket up or down.
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.
