NOTES
Spring & Solenoid Operations are contingent on
the lock arm tabs being square to the lock arm body.
With exception to fail-lock clockwise (
A
), the solenoid will be
mounted to the back of the slots. Then the lock arm tab will
be used to adjust the spring tension (see illustration to the
right).
Solenoid mounting screws must be tightened to 30 in-lbs.
to avoid slippage from continuous use.
