Align the slide so that the shoulder with the drill holes points towards the •
piston coupling.
Push the slide onto the cylinder barrel.
•
Use a spring scale to check the displacement force of the slide (refer to the •
table in chapter 4.1.4 for the values) and if necessary, adjust the setting for
the sliding play as described in chapter 4.1.4.
Grease the second buffer. •
Observe the greasing instructions in the table at the start of this chapter
and the note on using shock absorbers on the end caps.
Insert the buffer into the cylinder barrel at the other end.
•
Grease the sealing ring and insert it into the buffer. •
Note
Newly inserted sealing bands and cover bands are generally too long and
protrude beyond the buffer. Shorten the bands as necessary so that they do
not protrude beyond the contact surface of the buffer (see band fastening on
the other side of the base profile).
Apply the band clamping mechanism to the sealing band and cover band. •
Apply Loctite 243 to the socket head screw and tighten it using the appro- •
priate torque (see table).
