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.
