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 

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 
workshops.  

  CAUTION Cables, switches, plug-in connections 

must be inspected by qualified staff every three 
months (requirement according to VBG4); the 
inspection results must be documented. 

 

 
 
6.2  Dismantling 
Prior to dismantling the hand extruder, pull the mains 
connector.  

 

The hand extruder must be at ambient temperature. 

 

Damaged mains connection cables must be 
completely replaced. “Mended” power 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 
 
When ordering spare parts, always indicate the 
serial number of the extruder.  
 
Make sure to use original spare parts only.
