Dismounting/Repair Brewing SystemService Manual FB50/55/5100/5500
The spring of the actuator is under
tension.
In case of a malfunction of the
actuator there is an increased risk
of injuries due to a sudden
expansion of the actuator spring.
If the brewer cylinder cannot be
opened (brewer cylinder/filter plate),
it is possible that the actuator does
not accept the spring tension, which
may be the case if:
- Date of manufacture before week
20/96 (see label or printing on
the actuator)
These actuators include:
1. Plunge holder not screwed
(screws visible from the bottom)
2. Plastic nut (guiding nut)
Reasons for actuator malfunction:
- broken plunge holder (plastic)
- actuator does not retract
- spindle stucks on the bearing
housing
- the axle (9) cannot be removed
and turned manually (fig. 5)
If in case of a malfunction the
described mounting order cannot be
performed, please proceed on your
own discretion.
Attention: Observe the safety
instructions in order to prevent
injuries.
