Before You Start
Review these instructions, with the following objectives at
each step:
• Need:
Inspect the drill an ensure that it does not already have
the lock valve. See page 1 for an illustration of the com-
pleted installation.
• Safety:
Hydraulic Lines may be under pressure even with trac-
tor circuits in Float.
Frame-mounted coulters have sharp disk blades under
the work area.
• Inventory:
Examine any called-for items and make sure all parts
are present.
• Comprehension:
Make sure the installer understands where each part is
installed, and what tools are required for the task.
Pre-Assembly Preparation
Work Location

4. Locate the valve block to be updated.
5. Clean the valve and hose connections of any oil, dirt
or other contaminants.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury.
▲ Reduce the hazard by relieving pressure before disconnect-
ing hydraulic lines.
▲ Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
▲ Assume lines are pressurized until bled. Slowly open
(“crack”) fittings.
▲ Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
▲ If an accident occurs, seek immediate medical attention
from a physician familiar with this type of injury.
