WARNING
!
Operating the steering wheel suddenly at high speed or
operating the steering wheel on steep slopes is dangerous.
Do not operate the steering wheel in such situations.
!
If the engine stops when the machine is traveling, the emer-
gency steering is actuated. Note that this system is only for
steering in emergencies, so never stop the engine.
!
It is particularly dangerous if the engine stops when the
machine is traveling on slopes, so never let the engine stop
when traveling on slopes.
If the engine stops, stop the machine immediately at a safe
place.
When traveling, use steering wheel (1) to turn the machine.
With this machine, the front frame is joined to the rear frame at
the center of the machine by the center pin. The front and rear
frames bend at this point, and the rear wheels follow in the same
track as the front wheels when turning.
Turn the steering wheel lightly to follow the machine as it turns.
NOTE
When the steering wheel is turned fully, if it reaches the end of
its stroke, do not try to turn it further.
Check that there is a play of 50 to 100 mm in the steering wheel.
Check also that the steering works properly. If any abnormality is
found, please contact your KOMATSU distributor for inspection.
When the emergency steering system detects that the oil pres-
sure in the steering circuit has been restored, the actuation of
the emergency steering system is stopped.
