When season changes and the weather becomes warmer, do as follows.
q Replace the fuel and oil for all parts with oil of the viscosity specified.
For details, see “FUEL, COOLANT AND LUBRICANTS (4-9)“.
q If for any reason permanent antifreeze cannot be used, and an ethyl glycol base antifreeze (winter, one sea-
son type) is used instead, or if no antifreeze is used, drain the cooling system completely, then clean out the
inside of the cooling system thoroughly, and fill with fresh soft water.

WEATHER 3
WARNING
If the steering wheel is operated and stopped while the oil
temperature is low, there may be a time lag before the
machine stops turninig.
In this case, use the safety bar to ensure safety, and per-
form the warm-up operation in a wide place.
Do not load up the hydraulic oil in the circuit continuously
for more than 5 seconds.
When the temperature is low, do not start the operation of the machine immediately after starting the engine.
