Grease the cylinder barrel and the sealing band and cover band. •
Observe the greasing instructions in the table at the start of this chapter.
Insert the sealing band in the cylinder barrel so that approximately 14 mm
•
of the sealing band protrudes from one end of the cylinder barrel.
Use your finger or a blunt object to press as much of the sealing band as •
possible into the guide slot from inside.
Thread the cover band into the fixture so that approximately 14 mm of the •
cover band still protrude.
Grease the piston and the band reverser. •
Observe the greasing instructions in the table at the start of this chapter.
Insert the piston into the cylinder barrel. Push the cover band into the slid-
•
ing notch on the band reverser with a screwdriver.
Note
When inserting the piston, make sure that the magnetic side of the piston is
opposite the cut-outs on the groove for the proximity switches.
The magnet is moulded-in and is thus not visible. Therefore its position can
be determined using a counter magnet (e.g. compass).
Push the sealing band under the band reverser with a screwdriver. •
Insert the piston fully into the cylinder barrel. •
