Turning - Komatsu WA380-6 Operation & Maintenance Manual

OPERATION

TURNING

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 emergency 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.
NOTICE
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 (2.0 to 3.9 in) in the steering
wheel. Check also that the steering works properly. If any abnormality is
found, please contact your Komatsu distributor for inspection.
