PREPEARING FOR USEThe loader will be supplied to retail dealer and further to the customer on atransport stand or mounted on the loader mounting pad of the forest trailer.Unpacking from the stand and preparing the loader for work is done in the followingway:24. Lift the loader onto a flat base. Lift the loader a little bit up with a lifter, withwhich the loader can be handled securely and cut the fastenings. Do not gounder the loader, and be careful against swinging and falling of the loader.25. Lift the loader either on the loader mounting pad or on the four point framemounted on the tractor frame, and fasten the loader with bolts and nuts (M24).If the loader is installed on the loader mounting pad having an oil tank, oil resist-ant silicon will be put between the flanges to avoid leakings. Don´t allow siliconto run into the oil tank. If the loader is fastened with the forest trailer and alsothe telescopic support legs are mounted, the upper fastener of the support legsmust be mounted under the fastening bolts of the loader on the back side of theloader at the same time. Tightening moment is 660 +/- 70 Nm.26. Mount the valve block with the tractor so that the control levers move withoutany hindrance and the valves can be easily controlled. Fasten the valve blockenough firm in order to avoid movement and falling. It is not allowed to haveunprotected pressurised hydraulic pipes in the control cabin.27. Connect the return and pressure hoses of the loader to the tractor hydraulicoutputs. The return hose is located in the left end, seen from the hoses, and thepressure hose is in the right end. The return hose is equipped with a femaleconnector, the pressure hose has a male connector. It is good to connect thereturn hose directly into the tank, so there will not grow any pressure in thereturn pipe line. Follow the connection instruction of the tractor manufacturer,however.28. If support legs is mounted mount them as next ones. Fasten the hydraulichoses of the support legs.29. Loosen the transport support in the transfer boom.30. Make sure that the levers of the valve move freely in the centre positions. Turnon the hydraulic supply.31. Bend the boom jib with a movement of the transfer boom so that the boom jib iscompletely bent. The grab has been fastened with the lifting boom, loosen thegrab from the boom very carefully because the grab can slip down during theloosening (risk for accident). Lower the grab by using movements of the boomjib. Be careful with the swinging movement of the grab when the grab islowering downwards, the grab or the hoses of the grab rotator can get brokenor the grab can break something when swinging.32. Put the front gate of the trailer in its position.33. Move all the movements of the loader some times back and forth from the endposition to the other, possible air in the system disappears. Be careful whenmoving the loader because the movements can be fast if there exists air in thesystem.34. When you have moved the loader, check tightening of the tightening bolts.Tightening of the bolts must be checked during the operation sometimes, aswell, tighten if needed. |
