PREPEARING FOR USE
The loader will be supplied to retail dealer and further to the customer on a
transport 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 following
way:
24. Lift the loader onto a flat base. Lift the loader a little bit up with a lifter, with
which the loader can be handled securely and cut the fastenings. Do not go
under 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 frame
mounted 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 silicon
to run into the oil tank. If the loader is fastened with the forest trailer and also
the telescopic support legs are mounted, the upper fastener of the support legs
must be mounted under the fastening bolts of the loader on the back side of the
loader at the same time. Tightening moment is 660 +/- 70 Nm.
26. Mount the valve block with the tractor so that the control levers move without
any hindrance and the valves can be easily controlled. Fasten the valve block
enough firm in order to avoid movement and falling. It is not allowed to have
unprotected pressurised hydraulic pipes in the control cabin.
27. Connect the return and pressure hoses of the loader to the tractor hydraulic
outputs. The return hose is located in the left end, seen from the hoses, and the
pressure hose is in the right end. The return hose is equipped with a female
connector, the pressure hose has a male connector. It is good to connect the
return hose directly into the tank, so there will not grow any pressure in the
return pipe line. Follow the connection instruction of the tractor manufacturer,
however.
28. If support legs is mounted mount them as next ones. Fasten the hydraulic
hoses 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. Turn
on the hydraulic supply.
31. Bend the boom jib with a movement of the transfer boom so that the boom jib is
completely bent. The grab has been fastened with the lifting boom, loosen the
grab from the boom very carefully because the grab can slip down during the
loosening (risk for accident). Lower the grab by using movements of the boom
jib. Be careful with the swinging movement of the grab when the grab is
lowering downwards, the grab or the hoses of the grab rotator can get broken
or 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 end
position to the other, possible air in the system disappears. Be careful when
moving the loader because the movements can be fast if there exists air in the
system.
34. When you have moved the loader, check tightening of the tightening bolts.
Tightening of the bolts must be checked during the operation sometimes, as
well, tighten if needed.
