Fuel Tank
WARNING! Be extremely careful with fire
such as cigarettes.
WARNING! Always stop the engine before
draining fuel.
Potential ignition may occur through spilled
fuel if disregarded.
WARNING! Always put in the fuel tank drain
plug and secure it after draining fuel.
WARNING! The fuel tank drain plug is
mounted directly below the machine.
To drain fuel, use outriggers to raise the
rubber track about 80 mm, allowing access
under the machine.
If the machine is unstable and sways, place
supports (stands) under the front and rear
sides of the machine to stabilise it.
• Fuel drain pan: Prepare a container according to
the remaining amount of fuel (12 L at the
maximum).
1. Place the machine on a level surface.
2. See “OUTRIGGER SETTING” on page 4-38
to set outriggers and raise the machine about
80 mm above the ground.
3. Place a container to collect the drained fuel
directly underneath the drain plug (P) of the
fuel tank.

NOTE: Remove the fuel tank cap if normal or
smooth fuel draining fails.
5. After draining the fuel, install and tighten the
drain plug securely.
6. See "OUTRIGGER STOWING" on page 4-48
to stow the outriggers.
