CAUTION: ALWAYS DISCONNECT POWER AND AIR BEFORE ATTEMPTING ANY
MAINTENANCE OR TESTING ON YOUR CASTLE MACHINE!
4.0 DRIVE CYLINDER SQE CLEANING
The drill solenoid is an air switch that controls the flow of air to the drive cylinder. The drive cylinder, in
turn provides the pressure to move the drill carriage through its cycle. If the air line becomes clogged the
drive cylinder may not have enough pressure to cycle the drill completely.
SOLUTION STEPS:
1. Open the back door
2. Inspect the hoses coming FROM THE DRIVE CYLINDER for holes and/or pinches.
3. Unplug the two DRIVE CYLINDER hoses from the solenoids. This is done by following the air
lines back to their connection at the control panel. The hoses should remain attached to the air
cylinder at the SQE’s (Fig. 4)
4. Dry cycle the machine:
a. Unplug the router motors
b. Hold in the safety stock sensors below the clamp with two scraps of wood. Be careful to
leave room for the router to come up through the work surface unobstructed!
c. Reach into the rear door opening and firmly grasp the yellow carriage.
d. Steadily pull and push the carriage fully back and forth to force air through the hoses. BE
SURE TO ALLOW THE AIR PRESSURE TO FULLY EXHAUSE OUT THE HOSES.
5. Make sure air is coming out of the
solenoids while dry cycling
6. The hoses attached to the cylinder
should exhaust air as you dry cycle
knocking loose any blockage out of the
brass SQE’s as well as cleaning any
debris out of the air hoses.
7. Press the hoses firmly back into the
push-in fittings.
8. Plug in the router motors.
