Installation
► Loosen the two M2.5x12 hexagon socket-head
screws (3) on the motor clamp fitting (4).
► Loosen the two M3x14 hexagon socket-head screws
(6) on the motor clamp fitting (5).
► Slightly loosen the four M3x5 hexagon socket-head
screws (1).
► Remove the toothed belt (7).
► Place the new toothed belt over the pinion of the Z
axis drive and the deflection wheels.
NOTICE!
Make sure that the teeth of the toothed belts engage in
the teeth of the pinion and deflection pulleys.
► Fit the tension jack (4) with the two fastening screws,
to the toothed belt.
NOTICE!
Make sure that both ends (2) of the tension jack lie on the
teeth of the toothed belt (1) .
NOTICE!
New tension jack
A new tension jack (fitted from 10/2007) has a profile
which engages with the toothed belt and therefore en-
sures a more reliable clamping.
