81 S450 Operation & Maintenance Manual
LIFT AND TILT COMPENSATION
Lift and Tilt Compensation is available on ACS and SJC equipped machines.
Description
Lift and Tilt Compensation can be used to adjust the lift
and tilt control sensitivity. This enables the operator to
increase or decrease the amount of control movement
before lift up, lift down, tilt back, and tilt out begins. The
operator can change each setting to their preference.
EXAMPLE: Your machine is being used with a
mower attachment. The mower slowly lowers
because you move the controls slightly when
passing over extremely rough ground. Adjusting
the lift down control to a low setting will provide
an increased neutral band and allow for more
control movement before the lift arms move.
The procedure that follows provides a starting point for
the lift and tilt control compensation. Operators can
adjust the settings to account for attachment weight,
engine rpm and application.
Operation
NOTE: Lift and Tilt Compensation should be
performed when the machine has been
warmed to operating temperature and any
attachment has been removed.
