What if …
…accidentally the cam got moved before installation?
As long as the code has not been changed with the change key, the lock can be prepared for
mounting following the steps below:
1. Hold the lock so that you look at the cover and the bolt is to the right.
2. Turn the cam clockwise minimum 4 complete turns and stop when the cam is lined up as
shown in figure 1.
3. Turn cam counterclockwise until lock opens. The cam should be lined up with the “LOCK
OPEN” line on the cover (see figure 2).
…the dial is hard to turn or the dial is rubbing on the dial plate?
Loosen the screw that holds the shaft in the dial and pull out the dial slightly. Then tighten the screw
hand tight. Do not over tighten as that will pull the dial back in. Use liquid thread-lock like Loctite™ if
required.
