7.4.1.2 Check the drain hose for damage – look carefully as the bore
of the hose can be crushed even when the outside of the
hose looks to be in good order at a casual glance.
7.4.1.3 Check the drain hose point of entry into the base machine
hydraulic oil system – it is always best to run it directly to
tank.
