MAINTENANCE INSTRUCTIONS

8Re-assemble the Model 880 exposure device by performing the following steps:

Apply PermantexTM anti-seize thread lubricant to the first several end threads of the back plate’s (locking mechanism) four 5/16-18 x 1½ in socket button-head screws. Align and attach the locking mechanism assembly to the exposure device’s end plate by installing the four 5/16-18 x 1½ in screws using a tamperproof tool bit mounted in a calibrated torque wrench. Torque the tamperproof screws in an opposing cross pattern to 110 in/lbs (12.43 Nm), ± 5 in/lb (0.57 Nm).

Operationally test the function of the entire system using a bayonet-fitting source guide tube, the remote controls and a mock source assembly.

Attachment of the bayonet source guide tube to the outlet port must be smooth and without resistance. Rotate the outlet port mechanism to enable exposure of the mock source assembly.

Connect the (serviced) remote controls to the mock source assembly connector and the device locking mechanism. Push the lock slide into the EXPOSE position and crank the control cable into the exposure mode. While cranking the mock source assembly from the exposure device, carefully feel for resistance or snags. During retraction of the mock source assembly back into the exposure device, carefully feel for any resistance or snags during movement. Conclude the test by verifying the lock slide automatically secures the mock source assembly. Action of the lock slide should be smooth with an audible ‘snap’ during automatic securing. After automatic securing, attempt to expose the mock source assembly from the exposure device to confirm a positive capture. Repeat this testing several times. If resistance, snags or sluggish movement of the lock slide is discovered during this testing, remove the outlet port and locking mechanism plates to determine the cause. Repeat all safety function tests if any additional servicing is required.

Clean the Model 550 jumper gauge in solvent. Lubricate the inner sleeve with light oil while moving the sleeve back and forth. Apply a light coat of oil over the entire jumper and insert back into the spring clip of the locking mechanism’s protective cover.
