Some friends have bought an old Wicksteed Saw. The unit has an Hydraulic
lift unit painted red with oil retained in the Annulus of the cylinder.
There is a rotating lever on the top to control down feed and a rotary
valve on the bottom to switch between down and up feed. When running and
in up feed it feeds up very slowly. The question is is it likely to be
the piston seal leaking or is the oil the wrong viscosity? I have seen
150 SAE mentioned on some saws. The oil in the cylinder is definitely
thinner than that!
It appears that the unit should switch off when in the top position does
anyone have any information or pictures of what the original electrical
control was like?
Thanks for the help
