The return-to-dig function is activated by pressing and holding the return-to-level, dig, float button, located on the right
joystick console, and then pushing the right joystick forward. The electronic control box controls this system. It moves the
bucket to the horizontal position regardless of the previous position of the bucket or the loader arms.
Three different return-to-dig modes can be selected, depending on position of loader mode selector. The three modes are:
(1)
Mode 1 - Ready for return to dig. Using this selection, the movements of the loader arms and the bucket are
coordinated to bring the arms to a height of approximately 24 in. (60 cm), with the bucket in a relatively flat
position. In this position, the yellow, floating position indicator flashes. To complete the sequence and start to dig,
push return-to-level, dig, float button again without moving joystick. The loader lowers to the lowest level, placing
the bucket flat on the ground. The loader arms are now in the float position, and the float position indicator
remains on.
(2)
Mode 2 - Auto return to dig. As in Mode 1, the movements of the loader arms and the bucket are coordinated. The
bucket is placed flat on the ground with the loader arms in the float position. As in Mode 1, the yellow, floating
position indicator remains on.
(3)
Mode 3 - Float position. The loader arms take up the float position and the bucket stays in its previous position.
Floating can be cancelled by pulling back on the joystick. When this mode is selected, the float position indicator
flashes. The bucket does not automatically assume a horizontal position on the ground in this mode.
The following features are incorporated in the design of the FEL:
(a)
Antirollback device. This device prevents the bucket from dumping material on the cab when the arms are
raised and does not function when vehicle is in EMERGENCY or CROSS COUNTRY DRIVING mode.
(b)
Bucket leveling control. During raising or lowering of the loader arms, the bucket remains at a constant
attitude. This is useful in certain applications such as operating with the forklift attached.
Manual level indicators are located adjacent to the bucket tilt cylinders. These devices indicate when the bucket or forklift is
level on the ground. When aligned, the yellow level indicator on the right side indicates that the bucket is level and on the
ground. The red level indicator on the left side indicates that the forklift is level and on the ground.
