SCHEME OF ASSEMBLY
PREPARATION
4 M10 bolt and 4 M10 nuts are required for dir. lock 401216; M14 bolt and nuts are required for dir. lock 401217-401226 and M16 bolt and nuts are required for dir. lock 401227. Self-locking nuts and 8.8 bolt strenght are recommended. The length of the bolt depends on the characteristics of the trolley the castors have to be fitted onto (it should be usually longer than 40mm).
INSTALLATION
The directional lock and the castor have to bee positioned and subsequently fastened as per the exemplification in the adjacent picture (note: the picture shows the bracket without the wheel for handiness of the image only).
FASTENING
The bolt has to protrude through the nut by al least 3 threads.
The proper tightening of the bolts has to be verified by a torque wrench. The recommended tightening torque of a self-locking nut is of 48Nm for dir. lock 401216, of 130Nm for dir. lock 401217-401226 and of 205Nm for dir. lock 401227.
FINAL CHECK
Make sure that the directional lock engages properly into the slots of the bracket and that the castors are aligned to the direction of movement of the trolley once the the directional lock is applied.
