Both two-function and three-function control levers use full forward detented position, for "FLOAT" operation.
Two-function control lever has a momentarily detented position (full right) used to fast dump the bucket.
Additional third-functions are controlled by handle-mounted switch.
NOTE:
Roman numerals do not apply to this application.
1.
A single function operates when control lever (A) is moved straight away from center, in one-of-four primary directions (front, back, left or right).
-
Front-Boom Lower (B)
-
Full-front (I) is a detented position used for "float" operations.
-
Back-Boom Raise (C)
-
Left-Bucket Rollback (Curl) (D)
-
Right-Bucket Tilt (Dump) (E)
-
Two-Function Control Lever:
Full-right (J) is a momentarily detented regenerative position where return oil is used to fast dump the bucket.

2.
Two functions operate simultaneously when lever is moved at 45° angles from primary directions, into a two-function zone (F). Two-function zones are: Boom Lower/Bucket Dump, Bucket Dump/Boom Raise, Boom Raise/Bucket Curl, Bucket Curl/Boom Lower.
3.
When lever is released to spring-centered neutral position, mid-mount valve holds boom and bucket in position.
4.
Cylinder operating speed depends on how far from center the control lever is moved. When lever is first moved from center, hydraulic functions operate slowly (G), then move progressively faster as lever is moved further away from center, out to fast speed operating position (H).
"Float":
Push lever full forward into detent when "float" is desired. "Float" position (I) allows loader boom to move up and down freely while traveling over rough ground. Manually return lever to neutral when "float" is no longer needed.
