•  Insert the retaining ring.

Note

Check that the retaining ring is correctly positioned.

All sizes

•  Clean the inside of the cylinder barrel and guide rods using a cloth and air 

gun.

•  Carefully push the slide onto the guide rails in the cylinder barrel.

4.3.2 

Setting the track roller pretension

The roller bearings must be set using the eccentric screws so that the displace-
ment resistance for the slide is as low as possible and it can move without 
backlash.

Note

The track roller pretension is set with the two inner track rollers via eccentric 
screws. It requires a high degree of mechanical awareness.
The pretension is set without the toothed belt attached.

•  Unscrew the hex nuts of the eccentric screws and apply Loctite 243 to them.

•  Replace the hex nuts on the eccentric screws, but do not tighten them yet.
