SECTION 2 – OPERATION
2-30
TWO LEVER CONTROLS
POSITION CONTROL OPERATION
Position control is obtained by placing the draft
control lever
②
all the way forward and then
moving the outer (Position) control lever
①
to
position the equipment as desired. The outer
(Position) lever is used to set the desired working
height or depth.
DRAFT CONTROL OPERATION
Draft control is obtained by placing the position
control lever in the forward position. Use the draft
control to adjust the draft setting by draft control
lever positioning to rearward as desired (the lift
system will automatically maintain the selected
draft as described above).
OPERATING IN BOTH POSITION AND DRAFT
CONTROL
The position control may be used together with
the draft control as follow:
1. Set the position control lever
①
at the
maximum desire implement depth. The
hydraulic system will not lower the implement
below the pre-selected depth. (This will also
prevent “diving” which may be encountered
with light equipment, such as a rear blade,
when grading or backfilling.)
2. Position to rearward the draft control lever
②
for the maximum draft load (pull) desired.
The hydraulic lift system will now provide normal
draft response within the range set by the
position control. This adjustment provides a more
uniform depth while maintaining an even pull in
widely varying soil conditions
.
WARNING
Make sure the area is clear of people before
lowering equipment.
