Thread: Help with Excalibur EX21

your first mistake was buying the thing

at the left hand side at the back just above an inspection plate you will find a screw with a nut on it loosen the nut and turn the screw out a small amount and lock the nut again
it works on a friction so it will get loos again as it wares a groove and the arm will full on its own so the adjustment must be maintained

let me know how you go

Patch,

Thanks for the info.
The adjustment you mentioned did not help initially, so I removed the cover held on with three black socket head screws. Discovered the screw nearest the main arm pivot bolt was too long, and was preventing the arm from moving anywhere. Added enough washers so the the screw did not protrude past the inside edge of the main frame; problem solved. Now the adjustment you advised helps, allowing the ball bearing detent to hold the arm up, and let it down as required.
