Remote control maintenance requirements
1 Disconnect the remote control unit from the exposure device.
2 Straighten out the remote control housings on a work surface, then remove the control
cable from the remote control conduits (661 safety connector side) until it stops (a stop
spring on the end of the control cable). Rubber gloves are recommended for this operation.
Do not use excessive force during removal of the control cable. During removal of the
control cable, it should be coiled in loops no less than a 12in (305mm) diameter and secure.
3 Disconnect the remote control conduit fitting from the control crank using the
11
/
16in
open-end wrench. Remove the stop spring from the end of the control cable and pass the
control cable through the crank gear to completely disengage. Label the remote control
conduits for proper assembly after the servicing.
4 Pull the remaining control cable through the 661 safety connector and secure.
5 Using the
11
/
16in open-end wrench, remove both remote control conduits from the 661
safety connector and the control crank.
6 Thoroughly clean the control cable using a brush in a degreaser bath. Use compressed air
to blow off residual solvent after the degreasing operation. Be sure to follow the solvent
manufacturer's safety recommendations.
