6. Cleaning and Maintenance
Disconnect the machine from the
works mains before all cleaning
and maintenance work!
6.1 Daily Cleaning After Completing
Work
Trouble-free, continuous operation can be ensured
only if the hook cutter is permanently kept in a
clean, hygienic condition. The machine should nor-
mally be disinfected before each cleaning.
Observe the applicable safety and hygiene regula-
tions (EN 1672)!
Disinfectants must not be allowed to come into di-
rect or indirect contact with foodstuffs. Rinse the
machine with clear water after disinfection.
Do not use aggressive solvents! Do
not use steam or high-pressure
cleaners! Do not immerse the unit
in water!
6.1.1 Disinfection
Disinfect the machine during operation after every
cut with hot water (82° C).
6.1.2 Cleaning the cutter
Clean the machine after use with a cloth, brush and
warm water (40 - 55° C). Stubborn or encrusted dirt
and residue must be soaked beforehand. Clean us-
ing a cleaning agent, preferably as a foam, that is
applied to the surface to be cleaned and allowed to
work in for 15 - 20 minutes. Subsequently wash off
the dissolved soiling manually with warm water.

stance and must be used and disposed of according-
ly. On no account may hydraulic oil drain into the
