Disassembly (Fig. 35)
IMPORTANT: Make sure to remove and neutralize
chemicals from spray components before disas-
sembly. Wear protective clothing, chemical resist-
ant gloves and eye protection during repair.
1. Park machine on a level surface, stop spray pump,
lower spray booms, stop engine and engage parking
brake. Remove key from ignition switch.
2. Loosen hose clamp and remove supply hose from
tee fitting on spray boom (Fig. 36).
3. Support spray boom to prevent it from falling.
4. Loosen two (2) cap screws (item 10) and lock nuts
(item 11) to allow breakaway springs (item 16) to fully ex-
tend.
5. Disassemble boom hinge as required. If pivot brack-
et (item 4) is to be removed from machine, disconnect
boom lift cylinder (not shown) from pivot bracket (see
Boom Lift Cylinders in Chapter 4 − Hydraulic System in
this manual).
6. Clean all removed components. If pivot bracket was
removed, inspect bushings (item 6) and pivot pin
(item 12) for damage or wear.
