Topping up and bleeding the cylinder (Cut Control System)
Topping up the head cylinder
This operation is done when the oil in the hydraulic cylinder compensator tank is
low.
First the cylinder head is brought to the HUL (Head Up Limiter) position so that
the oil level in the compensation tank (see photograph below) can be checked
using the rod. If the rod upper ring location is not visible, the oil level is insuffi-
cient.
To top up the oil in the tank, the instructions are as follows:
" keep the head in the HUL position (fully up) by closing the head descent reg-
ulator;
" unscrew the filler valve cap;
