Unlocking lock
• (A) – Extend about 35 mm (0.11 ft), so that the
cutout (4) is accessible.
• (B) – Screw a bolt into the bore (1). The locking
pins (2) must retract behind the telescopic
section (3).
If necessary, give the locking pin (3) a slight
knock to help this procedure.
• Unlock the lock on other side of the telescopic
section as well.
Locking the telescopic section
• (A) – Retract the telescoping until the locking
pin (2) is in the middle of the opening.
• Unscrew the bolt from the bore (1) until the
locking pin (2) is extended completely.
• Remove the bolt from the bore (1).
• (B) – Retract the telescoping further until the
telescopic section is set down.
S
Risk of damage due to a mechanically released lock!
Under no circumstances may you operate the telescoping cylinder (alone) whilst
the lock is mechanically released. Unscrew all bolts out of the bores immediately
after finishing the repair work.
This prevents damage to the telescoping cylinder and the locking system.
