1. Tape (after 2 hours) 2. Cylinder rod movement
8. Leave the machine parked for 2 hours and monitor the lift cylinder. The
weight of the cutting unit may cause the lift cylinder to gradually extend. Use
the tape location to determine lift cylinder rod movement (
Figure 108 ).
A. If lift cylinder rod movement is less than 31.7 mm (1.250 inches) after 2
hours, ensure that the cutting unit has not settled to the ground. If the
cutting unit is still suspended after 2 hours and lift cylinder rod movement
is less than 31.7 mm (1.250 inches), consider that the lift cylinder is in
good condition. A cylinder in good, usable condition will show minimal
movement.
B. Rod movement in excess of 31.7 mm (1.250 inches) after 2 hours
indicates that the lift cylinder may have internal seal damage or excessive
wear. Remove and inspect the lift cylinder; refer to
Lift Cylinder (page
6–216) and Servicing the Lift Cylinder (page 6–219) .
9. Once lift cylinder condition has been determined, use a jack to raise the lift
arm slightly which will remove the load from the lift cylinder. Allow the jack to
support the lift arm and to prevent it from lowering. Remove the cap from the
cylinder fitting and the plug from the hydraulic hose. Connect the hydraulic
hose to the lift cylinder fitting.
