B2.1.3. Double-jointed scissors arm
WARNING! IMPORTANT!
The two main parts of the scissors arm are held together with a tie band. The band
MUST NOT BE REMOVED
until the two ends of the arm are fixed to the wall extension arm
(already secured) and to the X ray tube head. If the tie-band comes loose before the arm has been
fixed in place, the abrupt spring-back movement may damage the arm itself and above all may
injure the installer. Due to its preloaded spring, the double jointed scissors arm cannot be used
unless the related extension arm and tubehead are in place.
Assembling the arm:
1. Check that the friction mechanism (
1
) assembled on the extension arm at the end where
the scissors arm is mounted has been loosened, so that the arm can be inserted
correctly without damaging the friction mechanism.
2. Insert the scissors arm pin into the extension arm; keep the scissors arm tightened during
this operation. The cable and the braiding coming from the scissors arm must be pulled out
from the extension arm.
NOTE:
You must keep the scissors arm at right angles to the extension arm in order to be
able to insert the pin into the bushing placed inside the extension arm.
3. Insert the cable coming from scissors arm inside the extension, following the diagram
shown below.
4. Run the cable inside the extension arm until it comes completely out the opposite end.
Insert the cable inside the rotation pin as shown in the illustration below.
5. Check that the scissors arm is perfectly inserted; check that the rotation of the scissors arm
inside the extension arm is the one ergonomically
required by the operator, otherwise work on the
friction mechanism (
1
) until you get the desired operation.
NOTE:
The friction mechanism also serves to prevent
the scissors arm from becoming detached and for this
reason it must never be loosened completely.
6. Assemble the tubehead (see section B2.1.4)
