275 SERIES II MM190 (12---89)
If an LPG fuel tank is damaged or leaking, it should
be removed to a designated safe area, and the
proper personnel should be notified. Do not attempt
to make repairs to the tank, regardless of condition.
Repairs or disposal must only be made by qualified
personnel.
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. Care should be taken to insure that
the tanks are stored in such a manner 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. They 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.
The tank changing operation presents an
opportunity for the machine operator to carefully
observe the tank, fittings, and the fuel lines and
fittings for his own satisfaction. If abnormal wear is
detected, the operator should report it to the
appropriate personnel for action.
TO CHANGE AN LPG FUEL TANK
1. Park the machine in a designated safe area.
WARNING: Fuel vapor is present when
servicing fuel system. Fire or explosion can
result. Keep flames and sparks away.
2. Close the tank service valve.
3. Operate the engine until it stops from lack of
fuel, then set the machine parking brake.
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.
WARNING: LPG fuel is very cold. Frostbite
can result. Wear gloves when connecting or
disconnecting LPG hoses.
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 (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 pin
locator in or out.
11. Fasten the tank hold-down clamp to lock the
tank in position.
