WARNING

!

To avoid serious injury or death:  Hydraulic fluid under high 

pressure can penetrate the skin and/or eyes causing a serious 

injury. Wear protective gloves and safety glasses or goggles 

when working with hydraulic systems. 

The steps listed below must be followed before installing 

this kit:
1. If the front loader is not attached to the tractor, skip to 

step 8. Otherwise, continue with step 2 below.

2. Lower loader arms fully down, turn tractor off, and 

relieve all hydraulic pressure to the front loader 

couplers by operating the loader control lever(s) in all 

directions. 

3. Having released all hydraulic pressure, lock the 

control lever(s) from moving.

4. Remove all mechanical connections securing the 

front loader to the tractor.

5. Disconnect all hydraulic lines from the front loader. 
6. Refer to your tractor/loader Operator’s Manual for 

additional unhooking instructions.

7.

Restart tractor and slowly back away from the loader.

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

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

key to prevent unauthorized starting.

9. Place chocks in front and back of the tractor’s rear 

wheels.

10. As a safety precaution, disconnect the battery cable 

from the battery’s negative (-) terminal. Move 

negative cable away from the terminal to avoid 

accidental contact.
