OPERATION

5. Transport Locks

a. Always install the Transport Cylinder stops on the Earthmaster before transporting the Earthmas-

teron the road.

6. 6. Hydraulics/ Sequence Valve

a. a. The sequence valve comes factory set to activate at 1800 PSI.

b. b. When hydraulic pressure is applied to the main lift circuit the main lift cylinders on the axle will

beginto lift the unit. When the Main lift cylinders reach full extension, the sequence valve diverts

the hydraulicflow to the tongue cylinder to level the unit.

c. c. When hydraulic pressure is reversed, the tongue cylinder will retract lowering the front of the

Earthmaster.When the tongue cylinder is fully retracted the sequence valve diverts the hydraulic

flow back to the mainlift cylinders allowing them to lower the unit into the ground.

d. d. NOTE: The raising and lowering of the unit can be reversed at any time during thesequence

without causing problems.

9. PRE-OPERATION INSPECTION AND SERVICE

Before each use, a pre-operation inspection and service of the implement and tractor must be performed.

This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped

and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection

reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing

parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time

and repair cost can be avoided. OPS-U-0029

Always disconnect the main PTO Driveline from the Tractor before performing service on

the Implement. Never work on the Implement with the tractor PTO driveline connected and

running. Rotating Parts, Blades or Drivelines could turn without warning and cause

immediate entanglement, injury or death.
