7.
Adjust the range "c" with nut (1) so that the tip (C) of pro-
tector (5) protrudes 0.5 to 1.0 mm from the sensory sur-
face (B) of all proximity switches (3).
8.
Adjust the auto tilt-in proximity switch (6) so that the dis-
tance (e) between centers of the bucket proximity switch
(3) and the auto tilt-in proximity switch (6) becomes 145.5
to 149.5 mm.
9.
Loosen the bolt (4), and adjust the clearance "d" between
the bar (2) and the sensory surface (B) of all proximity
switches (3) so that it is within 3 to 5 mm, and fix it.
Tightening torque: 14.7 to 19.6 Nm {1.5 to 2.0 kgm}
10. After adjustment, run the engine to raise the boom. Check that the lever automatically returns to “HOLD”
position at desired digging angle when the bucket is tilted back after the bucket DUMP operation.
METHOD FOR CHECKING BUCKET ANGLE
You can check the bucket angle during the operation with the
indicator at the top right side corner of the bucket.
(A) Top face of indicator
Top face (A) of the indicator is in parallel with the cutting edge.
(B) Side face of indicator
Side face (B) of the indicator is at a right angle to the cutting
edge.
PZ AUTO TILT-IN
This machine employs the structure to keep the tilt angle parallel to the ground while raising or lowering the
boom. The work performance with attachment such as fork, etc. is improved significantly.
This machine provides the PZ auto tilt-in function with which the bucket is automatically tilted according to the
boom RAISE operation for loading work. Select an appropriate setting of PZ auto tilt-in corresponding to the op-
eration environment so that the spillage can be reduced.
When the load is likely spilled out toward DUMP side
When the load tends to be spilled to DUMP side, set the PZ au-
to tilt-in setting to “Heavy”.
