Always turn off and remove the tractor key before
making any adjustments or performing any
maintenance.
1. Release system pressure by flipping boom-
section switches on and off without pump run-
ning.
2. Clean nozzles with an air hose with less than
30 psi. Periodically replace nozzles.
3. Check hoses, pumps, valves and fittings for
leaks. Always wear rubber gloves when mak-
ing repairs or adjustments.
4. Check sprayer for loose bolts, pins and hose
clamps.
Cables and Rollers
Refer to Figure 13
Inspect cables and rollers for proper rolling. If a
roller does not turn, inspect roller for dirt or other
imperfections on bearing surface.
Rollers have a self-lubricating bearing. Do not lu-
bricate bearings with oil. Lubricating bearing with
oil may cause dirt accumulation that jams roller.
Keep cables tight and spring compressed to
10 1/4 inches. See “Spring Arm Tension,” page
25.
Optional Hydraulic Elevator
Keep slide pads properly adjusted as explained
under “Hydraulic Elevator,” page 23. Do not
grease slide pads. Lubricating slide pads with
grease may cause dirt accumulation that jams el-
evator. If necessary, use silicone spray on slide
pads.
Optional Electric-Hydraulic Control
Periodically inspect electrical connections for cor-
rosion, wear or damage. Replace terminals as
necessary.
Inspect control harness for damage. Make sure
the harness has not shifted into a position where it
could be damaged by boom or elevator operation.
Inspect hydraulic hoses and fittings for leaks. Re-
place any hoses that show signs of failure.
Tighten any leaking fittings.
