DISASSEMBLY

During maintenance, a visual inspection of all parts should always be carried out. 

The components that require special attention are described in the following steps.

The following tools are required for maintenance::

 

„

Allen wrench with ball head 4 mm

 

„

Hexagon socket wrench insert (8 mm)

 

„

Round rod (brass or plastic) approx. Ø 4.0 mm

 

„

Rubber mallet

 

„

Allen wrench 2 mm (maintenance 2)

 

„

Open-end wrench (flats 19) Nozzles (maintenance 2)

 

„

Open-end wrench (flats 10), alternatively a flat nose pliers, width <4.5 mm (maintenance 2)

 

„

Vise with protective jaws (maintenance 2)

 

„

Face wrench (pin Ø 5.0 mm) (maintenance 2)

Info disassembly

All cylinder and hexagon head screws are coated with thread lock lacquer which makes it 

difficult to loosen the screws. Since we recommend to replace all parts included in the main-

tenance package, the dismantled maintenance parts (including Cylinder Head Screws and 

Hexagon Head Screws) can be put aside and disposed of later.

 

„

Remove the cover 5TM.000.1Y.33.C0.0

pos. 35 with the four hexagonal screws

wrench size 8 (SW 8). The cover may

stick due to screw locking lacquer on the

nozzle body. In this case, gently tap on

the side of the cover with a rubber mallet

to break the bond.
