Positioning the doors
46
The example below shows how to position the fuel loading door. The procedure is the
same for positioning the combustion chamber door.
❒ Using an Allen key (AF 13), loosen the lock nuts on the locking cams at the top
and bottom
❒ Close the door
➥ With a gap of approx. 2 to 3 cm there should be a noticeable resistance
❒ If the resistance is too low or too high, move the locking cams backwards or
forwards using the key provided (AF 32)
➥ The movement of the locking cams causes the hinged plate to move, allowing
the contact pressure to be adjusted
➥ Caution: The two locking cams (top and bottom) must be adjusted equally
❒ Close the door
❒ If the door will not close, move the locking cams forward slightly
➥ Caution: The two locking cams (top and bottom) must be adjusted equally
❒ Secure the lock nuts again
The locking plate can be moved in the same way using the locking cam at the side of
the door handle, allowing the contact pressure to be adjusted on this side
