position when the handle is released. The return spring
was properly adjusted at the factory. However, to adjust, if
necessary:
NOTE: Use hand on handle to return to position. Failure to do

MAKE CERTAIN
Fig.23
1. Loosen both nuts (A) and (B). Make sure that the
spring housing (C) remains engaged with head casting
(D).
2. While firmly holding the spring housing (C) pull the
spring housing out and rotate it (counter-clockwise to
increase or clockwise to decrease the spring tension)
until the tab (E) is engaged with the next notch on
the spring housing.
Because the return spring is under tension,
it will want to unwind (clockwise). Make sure you have a
firm hold of the spring housing before pulling it out.
3. Turn the nut (B) until it contacts the spring housing (C),
then back the nut (B) out 1/4 turn from the spring
housing (C). Tighten the nut (A) against the nut (B) to
lock the nuts from turning.
The inside nut should not contact spring
housing when tightened.
