Cap end of cylinder has greater volume and area than rod end.
Select R/L Balance from the Valve Setup Menu.
A screen similar to the one depicted appears.
Left side - Lift: Toggle the raise / lower switch to
raise and hold. The blade will oscillate up and
down. Observe the blade drifting up or down
during oscillation.
If the blade is drifting upward, lower the left hand
numeric value. If the blade is drifting downward,
raise the left hand numeric value. Test the
movement again and adjust until the blade is
balanced.
Right side - Tilt (for Lift & Tilt): Toggle the raise / lower switch to raise and hold. The
blade will oscillate about the tilt pivot point. Observe the blade drifting.
If the right side drifts downward, increase the right side numeric value. If the right side
drifts upward, decrease the right side numeric value. Test the movement again and
adjust until the blade is balanced about the pivot point.
Right side - Lift and Lift: Same procedure as the left side using the right side multi-
switch.

Set the machine throttle to normal operating RPM and place the blade approximately 1 foot
(0.3 m) above the ground. No laser is required.
R/L Balance - Dynamic Raise / Lower Balance
The valve raise / lower balance set-up allows adjustment to compensate for different raise and
lower blade velocities due to cylinder imbalance or for different hydraulic system responses
to different loads.
Most mobile equipment uses double-acting hydraulic cylinders. Double-acting cylinders are also
called differential cylinders because the effective area, and therefore the volume, of each end
of the cylinder is different. The rod end of the cylinder has less area and volume than the cap
end by the nature of the rod being present. This differential area and volume causes a different
force and velocity during extension and retraction - or raising and lowering for a lift cylinder.
