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. Reduce engine speed. Park tractor and attachment 

on solid, level ground.

2. Unhook the attachment from the loader arms, back 

away from attachment several feet, and lower loader 

arms until they are fully down.

3. Put tractor in park or set park brake, turn off engine, 

and remove ignition key to prevent unauthorized 

starting.

4. Relieve all hydraulic pressure to auxiliary hydraulic 

lines.

5. Wait for all components to come to a complete stop 

before leaving the operator’s seat.

6. Use steps, grab-handles and anti-slip surfaces when 

stepping on and off the tractor.

7.

As a safety precaution, disconnect the negative 

battery cable from battery terminal. Move cable away 

from terminal to avoid accidental contact.
