15OPERATING THE ENGINE
BEngine Stop (By manual)
[GR2020G]
The engine stops when the key switch is turned off. If the
engine does not stop, make sure the speed control pedal
are in neutral position, the PTO lever is "OFF", the mower
is lowered to the ground and the parking brake is set, and
then carefully get off the machine. Open the hood, close
the fuel cock and wait the engine stops. Then contact your
local KUBOTA Dealer immediately.
To avoid serious injury:
A Do not operate the machine until the engine
stop system is repaired.
WARMING UP
To avoid serious injury:
A Be sure to apply the parking brake during
warm-up.
For 5 minutes after engine start-up, allow engine to warm
up without applying any load. This is to allow oil to reach
every engine part. If load should be applied to the engine
without this warm-up period, trouble such as seizure,
breakage or premature wear may develop.
BWarm-up and Transmission Oil in the Low
Temperature Range
Hydraulic oil serves as transmission fluid. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in trouble in the hydraulic system or a damage
to the hydraulic clutch.
To prevent the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:
A Do not operate unless the engine is well warmed up. If
operation is attempted while the engine is still cold, the
hydraulic mechanism will not function properly and its
service life will be shortened.
A If noises are heard after the hydraulic control lever has
been activated and the implement is lifting, the
hydraulic mechanism is not adjusted properly. Unless
corrected, the unit will be damaged. Contact your local
KUBOTA Dealer for adjustment.
