Pilot manipulating handle (Standard
configuration)
Pilot manipulating handle is installed on the handle manipulating
box on the right side of the driver seat. It is used for controlling
the working device to perform the operation. The bucket manip-
ulating handle with leftward and rightward manipulation is used
to control the bucket's movement and the arm manipulating
handle with forward and backward manipulation is used to con-
trol the arm's movement. This handle is at the "holding" position
under natural state, i.e., at the middle position.
When the engine is running, if you push the manipulating handle
rightward, the bucket will tilt forward; if you pull the manipulating
handle leftward, the bucket will tilt backward.
If you push the arm manipulating handle forwards, the arm will
lower; if you pull the arm manipulating handle backwards, the
arm will rise.
If you slightly move these two handles forwards or backwards,
or leftwards or rightwards, you can control the openness of the
main valve, which, together with the throttle openness, can con-
trol the movement position and speed of the working device in a
comparatively accurate mode.
Besides, the pilot manipulating handle also has the following
special functions:
1 Arm lifting limit:
If the manipulating handle is pulled backwards to the ex-
treme rear position, the manipulating handle will be stuck
by arm rise holding magnet (the manipulating handle will
not return back to the middle position even you release
your hand), and the arm will be rising all the time; when
the arm reaches the limit position, the arm limit switch is
actuated, the arm rise holding magnet is de-energized and
loses the suction force, and the manipulating handle will
automatically rerun to the middle position under the force
of spring and the arm will no longer be lifted.
