MEGA 230 / 350 CENTRIFUGAL OPERATORS MANUAL
4.6 Adjusting Center Cables (cont'd)
5. Alternating from side-to-side, tighten adjustment nuts (A) so floating
frame is square with stationary frame. Properly adjusted cables will
be very tight and only deflect a small amount (fractions of an inch)
when pulled on by hand.
DO NOT overtighten cables.
6. Tighten jam nuts (B).
7. Unfold boom to operating (spraying) position.
8. Fold boom and check that floating frame remains square to stationary
frame.
4.7 Attaching Feed Hoses - Three Valve System
IMPORTANT: DO NOT use petroleum based lubricants. They will
deteriorate hoses, causing them to weaken and leak.
Lubricate hose ends with liquid dish soap to make
installation easier.
To avoid rework, be sure of fitting locations prior to
attaching hoses. Plastic fittings use a very
aggressive hose barb which makes hose removal
difficult.
1. Route hoses from each boom section to control valve.
IMPORTANT: Ensure feed hoses have sufficient slack around hinge
to prevent hose binding when boom is folded. Feed
hoses should be routed over the H-frame and
strapped to the support bracket with enough slack to
ensure that there is no binding when boom is
lowered or raised. (Fig. 9)
2. Connect feed hoses to control valves. Right hand feed hose goes to
right hand section control valve.
3. Retain all hoses with tie straps.
