6 Maintenance/Inspection
Pull mains connector before carrying out any
maintenance and repair work on the hand extruder.
Maintenance and repair work on electrical tools may
only be carried out by qualified electricians.
The hand extruder together with the hot air
hood must have cooled down to safe-to-touch
temperature.
Observe the instructions under section “Safety“.
Maintenance and repair work may only be carried
out by qualified personnel or by our service staff.
To ensure the proper function of the hand extruder
over its entire service life for its intended service, we
recommend:
-
to have all maintenance, inspection and mounting
work carried out by authorized and qualified
personnel who are familiar with the operating
instructions,
-
to always shut off the unit before carrying out any
work on it,
-
to remount and reactivate all safety and
protective devices immediately after completion
of the maintenance/repair work.
During maintenance and repair work, make sure that
the hand extruder and its individual components are
firmly positioned.
In addition to the operating instructions and the
national and local accident prevention regulations
applicable at the place of use, the acknowledged
technical rules for safe and proper working practices
must be observed.
Any working practices posing a safety risk are
prohibited.
Activities other than those described in this
section may only be performed at the Manufacturer’s
workshops!
6.1 Maintenance/inspection of MEK/MAK hand
