8 System Maintenance
For good performance in corners, when driving over terraces or through ditches at an angle, or
in hard steer situations it is important to do the following:
1. The Teflon sliding pads on the boom must not grab in dynamic situations (corners, terraces
etc). See the photos below for the location of the sliding pads. Apply grease to the
complete surface of all sliding pads. Manually rotate the boom (by pushing on the ends) to
access the entire surface of the pads when greasing.
2. Check that the pin in the top of the cylinder is not loose and does not have any free
movement or slop. The bottom cylinder mounting bolt torque must be checked regularly.
The bolt must be tightened to 260 ft-lbs (350 Nm).
3. Ensure the sprayer operator continues this maintenance for proper operation.
It is recommended that the pads be re-coated with grease every 20 hours of
operation.
