Detailed view of lock bolt

C.4.3.b. Switching the marker arms to working position;
The marker arms are brought to upright position after
the work in order to prevent the marker arm to extend
and cause accident during transportation. Before the
work, the lock is released and it is switched to working
position. To switch the locked marker arm to working
position:
Note:
Switch the marker discs to travelling position
before the procedure.
1. Step:
Remove the spring catch on the marker
block.
2. Step:
Release the marker arm by unlocking
the lock bolt.
Since the marker arm makes the downward movement
with the pressure of the spring, it exerts a higher
pressure on the lock bolt than its own weight when in the
travelling position. Therefore, release the bolt by pushing
the marker arm towards the machine center before
opening in order to release the lock bolt. Released lock
bolt will be removed from its slot freely.
CAUTION:
Crash Hazard!
Lock bolt is the last safety element holding the
marker arm in lifted position. The arm will be lowered
when it is removed. Thus, before removing the lock
bolt, ensure that you hold the market arm tightly
enough with your other hand. Ensure that nobody
including you stands on the lowering route of the
marker arm during the procedure.
Take the necessary measures in surroundings since
the market arm can extend more than the foreseen
distance. Crashing of the arm to personnel during
lowering includes severe injury risk.
