HYDRAULIC CIRCUIT

CASE TRAINING CENTER
AUGUST 2000

Description of Operation

Arm Out 2 Speed Circuit

When the am is out, the discharged oil from A2 is supplied to the arm (1) spool via the central bypass oil
passage.
The discharge oil from A1 is supplied to the arm (2) spool through the central bypass oil passage via the
straight travel valve, and merges at the downstream of the arm (1) spool, then, flows into the rod side of the
arm cylinder via the holding valve. The returned oil from the bottom side goes back to the arm (1) and (2)
spools via the tank oil passage.
