Manual
Operation
(When Engine Stops or Hydraulic Circuit Troubles)
Even when the engine stops or hydraulic circuit
malfunctions thus leading to hydraulic operation stop,
manual operation is possible. However, naturally,
steering wheel requires a larger operating power.
If the steering wheel is turned when hydraulic circuit
ceases
to
operate, the worm shaft (3) which
is
connected with stub shaft (7) moves slightly by steering
force, then the worm shaft (3) and rack (piston) (2) have
same relationship with the manual steering gear.
