OPERATION
5. If the oil is above the H mark on the gauge, remove cover
(1), drain the excess oil from drain valve (P) at the bottom
of the engine oil pan, then check the oil level again.
6. If oil level is correct, securely tighten the oil filler cap and
close the engine hood.
REMARK
When checking the oil level after the engine has been oper-
ated, wait for at least 15 minutes after stopping the engine
before checking.
If the machine is at an angle, make it horizontal before check-
ing.

When adding fuel, never let the fuel overflow. This may cause a fire. If any fuel is spilled, wipe it up com-
pletely. Never bring flames near fuel because it is highly flammable and dangerous.

2. When fuel filler cap (F) is opened, float gauge (G) comes
up in proportion to the remaining fuel level in the tank.
Check that the fuel tank is full.
Inspect the fuel level both visually and with float gauge (G).
3. If fuel is found to be low, unscrew fuel filler cap (F) on the
fuel tank and add fuel through the filler port until float
gauge (G) comes up to the highest point.
Fuel capacity: 980 liters
Position of tip (a) of float gauge (G) when fuel tank is full:
50 mm.
4. After refilling with fuel, push float gauge (G) straight down
with fuel filler cap (F) and then tighten the cap securely.
REMARK
If breather hole (1) in the cap is clogged, the pressure in the
tank will drop and fuel will not flow. Clean the hole from time to
time.
