Key Combinator Service Manual 3–15
To reinstall the operating lever:
1. With the operating handle resting on the key combinator base, align
the holes in the operating lever with the holes on the lever branch
and slide the lever pin into position. The lever pin may be difficult
to insert in the holes. See
Figure 3.12 .
2. Using the circlip pliers, place the retainer ring around the lever pin
and secure the retainer ring in place. See Figure 3.12 .
3. Adjust the springs so the ends fit into the spring holes on the base of
the combinator housing. See Figure 3.13 . Place the other ends of the
springs into the spring slots on the operating lever frame.
4. With the springs in place, push the operating lever assembly back
into the key combinator housing so that the operating handle is
upright and resting against the combinator frame.
Caution
When pushing the assembly back into the combinator housing, keep
your fingers away from the springs so your fingers do not get
pinched.
5. Using a 5/32
″
Allen wrench, install the two front screws and tighten
until the operating handle is properly aligned.
