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 tem-
perature.
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 per-
sonnel who are familiar with the operating instruc-
tions,
-
to always shut off the unit before carrying out any
work on it,
-
to remount and reactivate all safety and protec-
tive 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 na-
tional and local accident prevention regulations ap-
plicable at the place of use, the acknowledged tech-
nical rules for safe and proper working practices
must be observed.
Any working practices posing a safety risk are pro-
hibited.
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
extruder
•
CAUTION After approx. 500 operating hours, the
hand extruder including drive unit must be
thoroughly cleaned and inspected. This work may
only be carried out at the manufacturer’s work-
shops.
•
CAUTION Cables, switches, plug-in connections
must be inspected by qualified staff every three
months (requirement according to VBG4); the in-

6.2 Dismantling
Prior to dismantling the hand extruder, pull the mains
connector.
The hand extruder must be at ambient temperature.
Damaged power cables and/or connecting cables
(between the Powerbox and the hand extruder) must
be completely replaced. “Mended” cables pose a
hazard to life and limb. Cable replacement is to be
carried out by qualified electricians only.
The safety precautions described under sections
“Safety“ and “Malfunctions, Causes and Remedies“
must be strictly adhered to.
6.2.1 Overview of spare parts/attachments
