HOW THE CYLINDER OF THE MIXER WORKS
Our cylinder is a simple effect cylinder. When the mixer is in working position or in
loading position (it is empty) you can see that the stem of the cylinder is all inside the
cylinder. To empty the mixer you have to lower the oil pressure, the weight of the
load will cause the return of the fluid to the reservoir and the release of the cylinder.
If you open the distributor increasing the pressure, the pressure of the oil will cause
the stem to go back inside the cylinder and this will bring up the mixer in working
position. So opening and closing the pressure of the fluid you can stop the mixer in
the position you want.
The frame is designed to allow attachment of the mixer to tractors equipped with 3 -
point hydraulic lift system (1st and "nd Category).
1) Once attached to the tractor it is necessary to remove the blocking knobs from the
support legs and place these legs in the position indicated in the design shown on
the adhesive decals.
2) Place the mixer as shown in "Position B" indicated in the diagram in this booklet
and block the lift bars of the hydraulic lift so that the PTO Shaft remains as nearly
as possible horizontal with respect to the power take-off of the tractor and the input
shaft of the cemental mixer. There upon carry out the link-up to the hydraulic system
of the tractor and verify - without rotating the mixer tub - that the PTO Shaft is in no
way subjected to forcing especially when in the " position C" of the diagram.
N.B. Ensure that in all positions, and especially in "position C" (the shortest), there
is at least 60 mm (2 ins) axial play in the PTO Shaft itself.
3) Start the power take-off of the tractor at the lowest r.p.m. and rotate the mixer tub
for a short period empty. During this test ensure once again that the PTO Shaft
does not force at the cross-pieces either in "position A" or "position C" of the diagram.
N.B. Ensure that the shaft never operates at an angulation of more than 35° as
illustrated in the diagram and also in the decals attached to the machine.
Before starting work the machine should be lubricated with care at points 1 and 2
indicated on the decals, at the ball joints and sliding tubes of the PTO Shaft, and also
on the chain drive sistem. Check the tension control mechanism.
Check the tension of the chain drive and if necessary regulate with the tension control
machanism. As to the position of the mixer during the loading and unloading phases
follow carefully the instructions indicated on the special decals attached to the machine.
