6. To install an animation wheel, check first that the wheel is perfectly flat. Slight warping of the wheel can
be corrected by applying gentle pressure. Then lower the wheel into the module so that its key will line
up with the slot in the hub. Place the wheel in position over the hub and apply gentle pressure from a
flat-bladed screwdriver as close as possible to the center of the wheel to press the wheel into position.
Check that the key in the wheel is engaged in the slot in the hub and that the wheel is held securely.
Rotate the wheel with a finger to check that it is seated flat against the hub and that it has not become
warped during installation. If necessary, remove, correct any warping and reinstall.
7. If no further service work is to be carried out, reinstall the module and head covers as described in
"Access to the framing module" on page 18 and "Access to the head" on page 17. Release the tilt lock
before reapplying power.
