1.
Open the air cleaner room door.
2.
Pull out the dipstick (G) and wipe the oil off with a cloth.
3.
Fully insert the dipstick (G) into the dipstick pipe, then pull
it out.
4.
Check it on the “ENGINE STOPPED” mark side.
It is appropriate if the oil level is between marks H and L. If
the oil level is below L mark, add oil through oil filler port
(F).
5.
Drain the excess oil when the oil level is above the H mark
of the gauge by referring to Steps 1. And 2., “METHOD
FOR CHANGING OIL IN PTO CASE”.
NOTICE
If excessive oil is supplied, drain it so that the oil level
becomes the correct level.
It will cause overheat.
METHOD FOR CHECKING COOLANT LEVEL, ADDING COOLANT
k k
WARNING
• Do not open the radiator cap unless it is necessary. When checking the coolant level, check it with
the reservoir tank when the engine is cold.
• Immediately after the engine is stopped, the coolant is still hot and the pressure is accumulated in
the radiator. You may get burn injury if you remove the cap in this state. Always wait for the temper-
ature to go down, turn the cap slowly to release the pressure, then remove the cap with care.
1.
Open the inspection hole cover (1) of the reservoir tank on
the front radiator side (right side of the machine body) of
the engine hood.
If the coolant level is within the range between FULL and
LOW of the reservoir tank (2) (2 pieces), the coolant
amount is at a proper level.
If the coolant level is below LOW, add coolant to FULL lev-
el through the filler port of reservoir tank (2) (2 pieces).
2.
Tighten the cap securely after adding.
NOTICE
If the reservoir tank is empty, leakage of coolant
should be suspected. After checking, repair any ab-
normality immediately.
3.
If the coolant level has been continuously low, check the
coolant level in the radiator.
If the coolant level is low, add Non-Amine Engine Coolant
(AF-NAC) of the same density as the one in the radiator.
