CAM LEVER ADJUSTMENT PROCEDURE

LM 20" MANHOLE ASSEMBLY

WITH ADJUSTABLE CAMS

Gaskets should be checked periodically for cuts or accumulation of

product and could result in sealing problems. Replace all damaged

gaskets.

Cam levers and wear plates need to be inspected for excessive wear in

the area where they make contact. If the cam lever opens easily with

minimal resistance, replace the worn components.
