1) High rubber springs are fitted to the pistons on the tipper. Cannot be lowered (unladen) to check spring travel.

2) The allocation of adjustment height to vehicle model may differ from the table in individual cases. In this case the correct adjustment height is to be determined by checking the lowering travel or shims under the pistons.
