Caution: All other nuts or plastic connectors not noted here must be tightened FINGERTIGHT!
Caution: Tighten the front wheel on the castor fork fingertight and without play! Apply micro-
encapsulated adhesive to the thread! INVACARE uses VIBRATITE VC3 for this purpose.
Caution: When reassembling the front wheel fork in the head tube, ensure that the fork is free-
moving! The union should be tightened fingertight, and should not result in stiff
movement of the head tube bearing.
