CORRECTIVE ACTION

bolts that connect links to clevis brackets.
Loosen the nuts a couple of turns so the
machine can still be operated. Operate the
machine a few revolutions to help seat the
pivot points. Retighten the six bolts and
install the clevis covers.
Levelers must be in contact with the floor.
Make sure that the leveler jam nuts are also
properly tightened.

Remove the clevis covers, and check for
damaged washers, retaining rings, and wave
springs. If necessary, replace. Remove the
end caps from lower link arm, and then
remove the bolt. Check that retaining ring is
correctly installed. Repeat for all pivot areas.
Remove bottom rear shroud (See How To...)
and inspect the position of the magnets to see
if they are rubbing on the aluminum disk. If so,
re-center the OPTO Sensor.
Verify that the connections between the
OPTO sensor and wiring harness are secure.
Bend the OPTO bracket slightly upwards.
Check for missing magnet or replace switch.
Verify that the transformer is plugged in.
Verify that the wiring harness is connected to
the console.
Check wiring harness in upright tube or at the
base frame. Verify that the harnesses are
properly connected.
If all connections are correct, replace
transformer, if this does not solve the problem
then replace console.
