TROUBLESHOOTING
LIFT ARMS
6. Inspect for leaks within the lift arm cylin-
ders.
a. Tilt the bucket slightly forward (about 10 de
-
grees) and bring the front edge of the bucket
down and into contact with the ground.
b. Check the left and right lift arm cylinders
individually. Disconnect the hose from the
cylinder not being checked and insert a plug
in place of the removed hose.
c. Disconnect the hose to the rod end from the
cylinder to be checked and release the oil in
the pipes within. Be sure to insert a plug into
the hose just removed.
d. Tilt the bucket backward and bring it up off of
the ground.
• If oil comes out of the rod piping and the lift
arms come down, you may assume that there
is a leak within the cylinder. If the lift arms
come down but no oil comes out, you may as
-
sume that there is a leak in the control valve.
