Adjusting the Return-to-Up
Spring
WARNING
Springs have stored energy. Overtightening
the springs may cause the springs to fail
which can cause serious injury or death and
damage to the machine and property.
Make sure that the return-to-up springs are
adjusted and/or replaced as instructed in this
procedure.
Check the gap between the spring bracket and the
end of the spring as shown in
. The gap
should measure 35 mm (1.38 inch). The adjustment
is made by turning the bolt at the front of each spring
(clockwise will shorten the gap, counter-clockwise will
lengthen the gap).

prevents uneven loading and possible damage to
the machine.
