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.
