Deployed Roll Bar Cannot Be Lowered Manually
If you receive customer reports in the above model vehicles that the roll bar once deployed cannot be lowered manually, this is due to a design change.
The roll bar can be lowered manually by removing the locking pawl hydraulic cylinder, refer to WIS document AR91.50-P-8400R. The locking pawl on
the support element (Figure 1, 1 and 2) was discontinued as of the above VIN number. The new version (Figure 1, 3) has a support element without a
retracting spring.
