WARNING
When adding fuel, never spill the fuel or let it overflow. It will cause fire.
If any fuel has spilled, wipe it up completely. If fuel has spilled over soil or sand, remove that soil or sand.
Fuel is highly flammable and dangerous. Never bring flames near fuel.
1. Turn the engine starting switch to the ON position and
check the fuel level gauge (G) on the monitor panel for fuel
level.
After checking, turn the switch back to the OFF position.
2. After completing work, fill the fuel tank through oil filler port
(F).
Fuel tank specified capacity: 165 liters
3. After filling, tighten the cap of oil filler (F) securely.
REMARK
If breather hole (1) in the cap is clogged, the pressure inside
the tank will drop and fuel will not flow. Clean breather (1) from
time to time and check that it is not clogged.
When carrying out work on slopes, check carefully that the fuel
level is high enough to prevent air from being sucked into the
engine when the machine is at an angle. Back face
