7 Troubleshooting
Warning: Electrical Hazard: Do not attempt to service Control Box components. Contact a Castle
Support Technician for proper service information.
7.1 Dry Cycle Test
Dry Cycling is an extremely useful troubleshooting technique if your Pocket Machine’s
performance and cycling sequence seem irregular or questionable. It affords the opportunity to
closely observe the mechanical, electrical, and pneumatic systems without routing pockets or
drilling holes.
• Locate the ON/OFF switches on the motor housings and turn them off, or simply unplug the
motors at the Control Box outlet.
• Connect air and power to the machine. Turn the machine’s Power Switch ON.
• Place a piece of scrap wood on the Table Top but do not cover the router slot. Align the
piece with one of the Safety Buttons so that the button can be depressed but the piece will
not block the path of the router bit or the drill bit.
• Start a Pocket Cycle by pressing the scrap of wood against one of the Safety Buttons and
stepping on the Foot Pedal. Observe the following actions in the described order:
The Clamp Foot extends to rest partly on the wood scrap while the router bit extends toward the
rear of the Table Top slot. Almost immediately the router bit returns beneath the slot and the
drill bit extends forward through the Pilot Hole under the Clamp Guard. Almost immediately the
drill bit retracts while the Clamp Foot releases the wood scrap. (The Clamp Foot will not release
until the final drill stroke is complete.)
