Remove the syringe from the pressure jacket in order to fully
inspect the pressure jacket. As a preventive measure, replace the
pressure jacket once a year.
WARNING!
Syringe pressure jackets must withstand pressures generated during
injection delivery. Defective jackets may shatter or explode under these
conditions. Always inspect pressure jacket closely before using injector.
Rotate the pressure jacket while viewing all areas; look for stress cracks
(around the front or at the shoulder area), discard any pressure jacket
exhibiting signs of stress, crazing lines or cracks. The use of such parts
may cause injury and/or an aborted injection.
Inspect the ram, seals and heater connector to ensure they are free
from dried contrast. If necessary, clean as directed in the section
Cleaning and Lubrication.
Check the powerhead pivot assembly to ensure that the pivot is
operating properly. Rotate the powerhead 180° to the inverted
position. If the pivot allows the powerhead to rotate to the non-
inverted position, tighten the pivot assembly screw as shown in
Figure 3-2b located in the Parts section. After tightening the screw,
ensure that the pivot still allows the powerhead to rotate.
Turn on the injector. Check the operation of the powerhead keys.
Make sure the keys are operating freely and not sticking.
Check that the ram correctly picks up the syringe plunger. Also
check for unusual powerhead noise while running the ram.
Check operation of the pressure jacket plate latch for each type of
face plate. Open and close the plate. It should operate smoothly
without interference or binding. Check for contrast build up. If
necessary, clean as directed in the section Cleaning and Lubrica-
tion.
Check the digital display for correct readings of volume and face
plate size.
