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.
