Adjust the lifting limit device for the arm
Be careful for the personal safety when performing the
adjustment of arm lifting height limit. Non-working persons
shall not approach the machine, and nobody shall stand in
the area near arm.
1.
Place the machine on a flat ground and the shifting ma-
nipulating handle at the Neutral position. Pull up parking
braking valve button, operate the pilot valve control lever to
raise the arm to the required unloading height, shut off the
engine and install frame-fixed bumper.
2.
Switch the starter key to ON position and connect the pow-
er supply for the vehicle. Toggle the pilot valve arm manip-
ulating handle backwards to the extreme rear position and
stuck by the magnetic force.
3.
Untighten Bolt "1" shown in diagram and rotate the limit-
ing plate "4" towards approach switch "2", making the ap-
proach switch "2" in line with the rear end (left end) of the
limiting plate "4". At this time, the magnetic force on pilot
valve just disappeared(the approach switch "2" indicator is
just OFF), and the pilot valve control lever auto returns to
the middle position; and tighten bolt "1".
4.
The distance between the approach switch "2" and the
limiting plate "4" shall be kept within 4~6mm. When rotat-
ing the limiting plate "4", rotating it counterclockwise will
decrease the limiting height, and rotating it clockwise will
increase the limiting height.
5.
After completion of the above operations, remove frame-
fixed bumper, start the engine and check whether the ac-
complished adjustment is appropriate.
