Adjustment of bucket limiting device
This machine is equipped with bucket positioning system, and
it has auto leveling and lifting limit function at any position. You
can effectively improve the working efficiency by rationally using
these functions.
Adjustment of bucket auto leveling device
1.
Place the machine on a flat ground and the shifting ma-
nipulating handle at the Neutral position. Operate the pilot
manipulating handle and put the bucket on a flat ground,
then pull up parking braking valve button, shut off the en-
gine. Install the frame-fixed bumper
2.
Untighten the bolt "1" as shown in the diagram, move the
approach switch assy "2" forward to make the approach
switch "2" completely coincide with limiting plate "4".
3.
Switch the starter key to ON position and connect the pow-
er supply for the vehicle. Toggle the pilot valve bucket ma-
nipulating handle backwards to the extreme rear position
and stuck by the magnetic force.
4.
Move the approach switch assy backward to make 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 indicator "5" is
just OFF), and the bucket control lever auto returns to the
middle position; and tighten bolt "1". The distance between
the approach switch "2" and the limiting plate "4" shall be
kept within 4~6mm
5.
After completion of the above operations, remove frame-
fixed bumper, start the engine and check whether the ad-
justment is appropriate.
