Adjustment of radial play
The play between roller and contact surface on the relevant beam must
not exceed 0.4 mm. Check using a feeler gauge. If there is more play
than this, the rollers must be replaced with oversized rollers. Oversized
rollers (rated) are available in increments of 0.4 mm.
When fitting oversized rollers, play may be < 0, provided that the mast
can be pushed together/drawn apart by hand, even if this proves diffi
-
cult to do. After a short period of use, the rollers will show an imprint of
the contact surface, meaning that play is > 0.
Adjusting the damper parts
The end position dampers are adjusted using washers so that the
damper stops the runners simultaneously on both sides, and the ends
of the beams are level at the end position - see the diagram.
