20 HARDI MEGA 230 / 350 CENTRIFUGAL OPERATORS MANUAL4.6 Adjusting Center Cables (cont'd)5. Alternating from side-to-side, tighten adjustment nuts (A) so floatingframe is square with stationary frame. Properly adjusted cables willbe 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 stationaryframe.4.7 Attaching Feed Hoses - Three Valve SystemIMPORTANT: DO NOT use petroleum based lubricants. They willdeteriorate hoses, causing them to weaken and leak.Lubricate hose ends with liquid dish soap to makeinstallation easier.To avoid rework, be sure of fitting locations prior toattaching hoses. Plastic fittings use a veryaggressive hose barb which makes hose removaldifficult.1. Route hoses from each boom section to control valve.IMPORTANT: Ensure feed hoses have sufficient slack around hingeto prevent hose binding when boom is folded. Feedhoses should be routed over the H-frame andstrapped to the support bracket with enough slack toensure that there is no binding when boom islowered or raised. (Fig. 9)2. Connect feed hoses to control valves. Right hand feed hose goes toright hand section control valve.3. Retain all hoses with tie straps.
