• If the Dry Cycle is successful, but a regular cycle fails when routing actual pockets
and drilling holes, check the Tooling, the Motor Operation, and the Drive Cylinder:
Procedures 21.83, 21.20 and 21.60
If the cycle stalls with the drill extended or if the clamp starts to extend and then immediately
retracts, check the Drill Stop Switch: Procedure 21.43
If the complete cycle takes significantly longer than two seconds, check the Air
Supply, the Pressure Regulator, and the Router Feed Rate: Procedures 21.92, 21.90
and 21.32
Note: A normal cycle when cutting pockets should take approximately 2 seconds.
If the complete cycle takes significantly longer than two seconds, check the Air
Supply, the Pressure Regulator, and the Router Feed Rate: Procedures 21.92,
21.90 and 21.32
Note: For comprehensive diagnostic descriptions and procedures refer to Section IV.
After testing is complete, turn the MAIN Power Switch OFF and switch both motors back ON or
plug the routers back in to the outlet.
Note: If a dry cycle is preformed to confirm function of the switches and the router bit or
the drill bit stays extended, verify that the carriage plate is not hitting the front of the switch/
magnet. The carriage plate should land in between the switch and the magnet.
