6.0 ADJUSTMENTS WARNING: • HARDI CANNOT ASSUME RESPONSIBILITY OR BE HELD LIABLE FOR ANY LOSS OR DAMAGE THAT OCCURS DUE TO LACK OF ADJUSTMENTS OR MAINTENANCE. • WE URGE YOU TO FOLLOW THE ADJUSTMENT AND MAINTENANCE RECOMMENDATIONS FOR EVERYONE’S SAFETY.
To adjust timing, loosen the turnbuckles on the front and rear cables until slack. Line up the chain and sprocket as indicated in step 1. Adjust front and rear cable tension (Section 6.10). Right Wing Sprocket Fig. 12 HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...
(C)(Fig. 14) contacts the top stop Fig. 14 plate with the outer and intermediate boom sections aligned. 3. Check to ensure that the lock nut is tight. HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...
IMPORTANT: Check boom alignment again. If front cable was tight- ened, the wing assembly will move forward; or if loosened, wing will move rearward. Adjust fold cylinder (if necessary) as described in Aligning Wing Assemblies, (Section 6.3). Fig. 15 HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...
Breakaway clutch cap screws (A)(Fig. 16) must be torqued to 40lb-ft (55 N-m) every week (40 hours) to prevent boom damage. Lubricate every day (8 hours) to ensure maximum perfor- mance and life. HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...
3. Apply an adjustable wrench to the machined surface at (B)(Fig.18). 4. Turn the cylinder rod until boom is level to the ground. 5. Secure jam nut (A)(Fig.18). Same procedure applies to both sides. Fig. 18 HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...
Fig. 20 6. Secure the jam nut (B)(Fig.20). 7. Pressurize cylinder to see if the boom is properly adjusted. If not, repeat the above procedure until it is correctly adjusted. HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...
4. Loosen the jam nuts on the turnbuckle. Adjust (tighten) the turnbuckle so that the outer wing section contacts the boom transport stop bracket. Tighten the turnbuckle another four complete turns and retighten the jam nuts. HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...

Therefore, in case of leaks; DO NOT overtighten any fittings (Fig. 24). Disassemble, check the condition and position of the O-ring or gasket, clean, lubricate and then reassemble. For radial seals (O-rings) (Fig.24) only hand tighten the fittings. Do not use pliers or wrenches. HARDI ® EAGLE 3PT BOOM OPERATORS MANUAL...
The O-rings need to be lubricated ALL THE WAY AROUND before fitting on to the nozzle tube. Fig. 24 HARDI recommends using a vegetable based oil to prolong the life of the O-ring. 7.9 Maintenance of Triplets (when fitted) Every 50 hours the triplets should be disassembled removed and cleaned.
