Circuit board removal

Unplug the control panel from both the cutter head and from power. DO NOT ATTEMPT
TO REMOVE CIRCUIT BOARD WHILE ENERGIZED!

screwdriver.
Control cable test
The cutter head depends on clear, uninterrupted signal from the controller in order to work.
Damage to cable ends can cause poor connection, leading to many problems. If after
troubleshooting the cause of a problem is still not evident, it is worth checking the continuity
between corresponding pin numbers of the cable. It may also be worth checking for shorts
between pins.
