Radiation Protection System Preventative Maintenance Checklist
1. This inspection is to be performed only on units with a body shield connected to a
swivel assembly. Performing this inspection on a system without the body shield
swivel assembly could cause irreparable damage to the balancer cable. Ensure
your system contains the body shield balancer swivel prior to executing this
inspection.
2. While the system is not in use, remove the body shield from its fixed position
inside the balancer. Lower the body shield until it is in a position where it is easily
maneuvered.
3. Rotate the body shield clockwise and counterclockwise for a minimum of three
(3) complete 360
o
rotations in each direction.
4. The body shield should rotate smoothly with minimal resistance. A single point
of resistance through a full 360
o
rotation is considered acceptable as long as
the resistance does not prevent full rotation. Replace the body shield balancer
connector assembly if any additional motion issues are detected. Contact a TIDI
Products authorized representative or TIDI Products service for repairs and / or
replacement of components. Replacement and repairs may only be completed by
TIDI Products authorized personnel.
5. Through each rotation, observe the cable to ensure the cable stays in a fixed
position and does not rotate with the body shield. A mark or a piece of tape can
be placed on the cable to improve the visual observation indicating if the cable is
rotating with the body shield or remaining stationary.
6. If the balancer cable is observed rotating with the body shield, the cable should
be inspected for damage and the body shield connector fixed / replaced by
authorized personnel. Replace the body shield balancer connector assembly if
the cable is rotating with the body shield. Contact a TIDI Products authorized
representative or TIDI Products service for repairs and / or replacement of
components. Replacement and repairs may only be completed by TIDI Products
authorized personnel.
Body Shield Vertical Travel Inspection (All Systems)
1. While the system is not in use, remove the body shield from its fixed position
inside the balancer. Lower and raise the body shield to inspect for motion issues.
The body shield should move freely up and down.
2. Adjustments to the balancer cable tension may be necessary to address any
issues. Refer to
Adjusting the Body Shield Vertical Tension
on page 14 for
guidance on addressing the drifting of a body shield.
3. If additional support is needed, contact TIDI Technical Service using the provided
contact information.
WARNING! RADIATION HAZARD
The Body Shield must be handled with care to avoid damage to the Body
Shield protective lead material. If the Body Shield is damaged, it must
be inspected according to the Body Shield and Face Shield Fluoroscopy
Inspection section of the User’s Guide
(TIDI Products document 84000).
