ADAPTOR SYMPTOMS
Platform harvesting unlevel.
Adaptor suspension level set
incorrectly.
Ground wheel airbag has lost
tensile pressure.
Platform is not balanced
correctly.
Platform adaptor spring has
lost tensile strength.
Re-set platform adaptor suspension.
.
Inflate ground wheel airbag as required.
Fit correct weight kit to platform.
.
Replace adaptor spring as required.
Platform lateral movement is
to rigid.
Adaptor suspension spring pre
-load set to high.
