AFTER STARTING ENGINE 3
WARNING
q
Emergency stop
If there has been any abnormal actuation or trouble, turn the starting switch key to the OFF position.
q
Do not carry out operations or operate the levers or pedals suddenly while the hydraulic oil is at low
temperature. Always carry out the warm-up operation for the hydraulic equipment until the hydraulic
oil temperature monitor is displayed green.
q
If the warm-up operation for the hydraulic equipment is not carried out thoroughly, and the machine is
moved, the reaction of the control levers and pedals will be slow and the movement may not be what
the operator intended. Always warm up the hydraulic equipment. In particular, in cold areas, always
warm up the hydraulic equipment thoroughly.
There are two types of warm-up operation: warm up the engine and warm up the hydraulic equipment. In addition,
depending on the environment, the method of carrying out the warm-up operation may differ, so carry out the
warm-up operation according to the items given in the appropriate section.
(When only the engine is warmed up, the hydraulic equipment is not warmed up, so always carry out the warm-up
operation for the hydraulic equipment separately from the warm-up operation for the engine. Warm up the hydrau-
lic equipment thoroughly ensures that the hydraulic oil is warmed up and that warm hydraulic oil circulates in all
the control circuits.)
Engine Warm Up 3
NOTICE
q
Do not accelerate the engine suddenly until the warm-
up operation has been completed.
q
Do not run the engine at low idling or high idling under
no load for more than 20 minutes. This will have an
adverse effect on the environment, and will also have
an adverse effect on the internal structure of the
engine. If it is necessary to run the engine at idling for
more than 20 minutes, apply a load from time to time
or run at a mid-range speed.
After the engine starts, do not start operating the machine immediately. First, carry out the following operations
and checks.
1. This machine is equipped with an automatic engine warm-up system, so if the engine water temperature is
below 30 °C after the engine is started, the engine warm-up operation starts automatically. When the engine
automatic warm-up operation starts, the engine speed is maintained at a speed higher than the normal low
idling speed.
If the engine water temperature goes above 30 °C or if the warm-up operation has been continued for more
than 10 minutes, the automatic warm-up operation is cancelled and the engine speed drops to the normal low
idling speed.
