Setting the sliding play on the slide 4.1.4
If new slide elements are inserted in the slide, the sliding play has to be set.
The setting for the sliding play is adjusted by turning the threaded pins marked
1
. This causes the respective toggle lever
3
to change the contact pressure of
the slide element
4
on the guide rail.
The trapezoidal shape of the guide rails distributes the contact pressure over all
three slide elements.
The sliding play setting is secured by tightening the side threaded pins
2 .
This causes the toggle levers
3
between the threaded pins
2
and the slide
to be clamped.

Remove the slide as described in • chapter 4.1.1 and remove the piston.
Unscrew the side threaded pins to secure the toggle levers (1). •
Unscrew the threaded pins to set the sliding play (2). •
Warning
The threaded pins are secured with Loctite 243 and may become damaged
if handled carelessly. If the internal hexagon socket is damaged (rounded),
it may still be possible to unscrew the threaded pin by driving in a Torx
screwdriver. Otherwise the threaded pin will have to be drilled out.
Re-cut all four threaded holes for the threaded pins with a suitable tapping •
drill in order to remove the residue of the locking agent.
Check the threaded pins for damage and replace them as necessary.
•
Place the slide, including the piston, on the cylinder barrel as described in •
chapter 4.1.2.
Push a feeler gauge (0.02 mm) between the upper slide element and the
•
guide rail.
Apply Loctite 243 to both threaded pins to set the sliding play and screw •
them in so that the slide rests on the guide rail backlash-free.
