Fine tuning
A final adjustment is necessary to ensure proper functioning of the hydraulic
system and power steering efficiency.
● Slowly move the spreader;
● Engage the power steering;
● While respecting the minimum turning radius, turn left and right with the
spreader;
● If the wheels turn too promptly, lower the hydraulic flow rate. If they turn too
slowly, increase the hydraulic flow rate;
● Test drive the power steering again until the wheels turn smoothly.
Step 5: Cables adjustment
Note!
Make sure the spreader and the tractor wheels are perfectly aligned
before adjusting the cables.
Note!
The power steering rubber seals are not shown in the following
illustrations.
● All previous adjustments must be
performed before proceeding with
the cables adjustment;
● Use a vise grip to lock the power
steering rod (1) on the flat bar
support (2) to hold the power
steering in neutral position;
● Adjust one cable at a time;
● Unscrew the adjustment nut (3) and
the cable nut (4) located within the
parallel bars for the corresponding
axle end;
● Move the protective envelope (5) to
obtain the same cable length (6) at
both ends of the cable;
● Secure both adjustment nuts (3).

● Tighten the cable nuts (4) to keep the protective envelope in place;
● Remove the vise grip;
● Test the adjustment. Move slowly the spreader and engage the hydraulics
of the power steering. Turn left and right to determine if the axles respond
to the command. When an axle responds too quickly while turning left,
readjust to extend the cable length at the axle end. If the axle responds too
quickly while turning right, readjust to shorten the cable length at the axle
end.
