OPERATING THE LOADER 20
The self-leveling valve has been factory-set to use the
boom cylinder fulcrum at the top position (A). When it is
switched to the bottom position (B), the self-leveling valve
must be readjusted.
How to adjust Self Leveling
A
When checking, park the tractor on flat and hard
ground, set the range shift lever in neutral, apply
parking brake, stay clear of operating area while
setting self-leveling.
1. Raise Leveling Adjustment
1) Set the jig on the right side of the loader pallet fork
as shown in the illustration.
2) Start the engine and set at 2000rpm.
3) Set the pallet fork flat on the ground.
A
When the pendulum indicates the vertical line of the jig
(marked "V"), the pallet fork is flat.
4) Raise the boom to the maximum height.
5) If the pallet fork angle is not within the angle shown
in the illustration, readjust the self-leveling.
A
When the pendulum indicates the white range of the
jig, the pallet fork angle is proper.
6) If the pallet fork angle is not within the angle shown
in the illustration, lower the boom and loosen the lock
nut then adjust by setscrew as follows.
*Pallet fork forward tilt: Screw "IN"
*Pallet fork back tilt: Screw "Out"
(Typically 1/2 turn is a good increment of change)
7) Tighten the lock nut
8) Repeat the procedures mentioned above
(from 3 to 7) until the raise self-leveling adjustment is
within specification.
