:
check that up/down movement of the broom is not blocked
by cables, ropes or strips wrapped around the main broom
hubs.
If main broom and the working pressure are in order, check the following
items:
- lower limit microswitch for main broom control (

Diagram): it could be jammed or burnt out
According to the version of the machine, the micro switch can be internal
(more recent machines) or external to the jack motor itself; according to the
case replace the micro switch or the complete jack motor. If the electric
motor of the actuator is not equipped with a 3 A fuse, get a suitable fuse
holder and install a 3 A rating fuse (see TSB IT 2000-012-01 in Section 5);
this suggestion is valid both for old jack motor with external micro switches
and for the more recent version with internal micro switches.
