Annual Maintenance For Extreme Condition Remote Controls - QSA Global SENTINEL SENTRY 330 Manual

4.4.4 Re-assembly of the Remote Control Unit
Reattach the remote control conduits to the safety connector assembly. Attach the EXPOSE sheath to the
EXPOSE side of the control crank assembly.
Lay the remote control conduits out in a straight line or a wide loop. Feed the end of the control cable into
the conduit as far as it will go. As the control cable is being fed into the remote control conduits, feel for
any resistance that indicates damage of the remote control conduit.
Turn the control crank handle in the RETRACT direction until the end of the control cable is protruding.
Screw the safety stop spring onto the end of the control cable approximately 2 in (50 mm) from the end.
Connect the RETRACT control housing to the control crank housing. Retract the control cable fully,
watching for any binding that may indicate damage to the control housing.
If applicable, reset the odometer to zero with the control cable fully retracted.
Replace the protective rubber cap over the end of the safety connector assembly.
