Initial Preparations

CAUTION

To avoid minor or moderate injury:

Hydraulic fluid and components that the fluid flows through

such as couplers, hoses, hydraulic lines, fittings and motor

become hot from use. Be careful when connecting and

disconnecting couplers. It is best to wear gloves and to allow

hydraulic fluid and hydraulic components to cool before

touching them.

The steps listed below must be followed before installing

this kit:

1. If attached, dismount loader from tractor. If loader is

not attached, skip to step 5.

2. Turn tractor off, then relieve all hydraulic pressure

from hydraulic lines by operating the loader control

lever in all directions. Proceed with locking the control

lever before dismounting.

3. Disconnect loader hydraulic lines from loader valve.

a. Refer to your tractor/loader Operator’s Manual for

additional unhooking instructions.

4. Restart tractor and slowly back away from loader.

5. Park tractor on a flat, level surface. Put tractor in park

or set park brake, turn off engine, and remove ignition

key to prevent unauthorized starting.

6. As a safety precaution, disconnect the negative (-)

battery cable from battery terminal. Move cable away

from terminal to avoid accidental contact.

attachment in the opposite direction.

Powering Off Third Function Valve Kit

•Turn power off to the Third Function Valve Kit by

pressing the power switch (#39) into its

decompressed position.

•The power switch LED light will turn off to indicate

the Third Function Valve Kit is powered off.

Relieving Hydraulic Pressure

Refer to Figure 1-29:

Be sure to relieve all hydraulic pressure from the tractor’s

hydraulic system before dismounting and disconnecting

the hydraulic lines. After properly shutting down the

tractor, follow procedure below.

1. Without starting the tractor, turn tractor ignition key

to the [ON] position.

2. Power on the Third Function Valve Kit.

3. Press both red button switches (#42) on the loader
