Loader Lift Spool

The loader lift spool operates in the same manner as the
18
A
auxiliary spool, refer to Auxiliary Spool.
The lift service spool (item 18) has a 'float' detent position.
The float facility is provided to allow the arms to move up
and down so that the shovel can follow the surface contours
as the machine is driven over uneven ground.
This is achieved by moving the lift spool 18 down beyond
'arms lower' into the 'float' detent. Both service ports are
connected to exhaust via the spool waists A.
Oil can then be displaced from either end of the lift rams and
into the exhaust gallery, allowing the rams to open and close
as required.
