Main clamping is wrong
adjusted (stroke 200 mm)
●
Stone layer is too large
●
Quality of the stones
●
Dimension of the stone layer
deviate from each other too
strongly

Stones are a little convex
(conditional of manufacturing)
●
Spacer of the stones goes only
to ¾ height of the stone height
●
Stone layer is gripped to far
above
●
Oil pressure is too low
●
Stone layer does not stand
even on the ground
●
The spacer of the stones avoid
the displacement
●
Toothing of the stones

REPAIR
●
Check the adjustments according
to the adjustment sticker
●
Adjust the gripping depth a little
lower, so that the steel lamellas
grip in the lower range of the
stone layer
●
Check the quality of the stones
●
Tighten the fixing bolts of the
steel lamellas in the problem
areas of the stone layer (thereby
stronger clamping force)
●
Grip tone layer as far as possible
in the lower range
●
Grip tone layer as far as possible
in the lower range
●
Grip tone layer as far as possible
in the lower range
●
Asked the manufacturer for the
necessary oil pressure

Set stone layer (palette) on even

Displace the stones via the
repeated opening and closing.
