Check Operating and Fluid Level

The Third Function Valve is now ready to be used with a 

multitude of attachments. Be sure to familiarize yourself 

with a complete understanding of how to operate the 

Third Function Valve Kit. 

DANGER

!

To avoid serious injury or death:  
Do not allow bystanders to be near the attachment, loader 

arms, or tractor during operation. They can become 

entangled, pinched, or crushed by the equipment. Disconnect 

and lockout power source before making adjustments or 

servicing tractor and attachment. 

1. Hook attachment to the tractor front loader and 

couple hydraulic hoses to the bulkhead couplers at 

the front of the loader. 

2. Raise attachment off the ground and operate the third 

function hydraulics using the push-buttons on the 

newly installed control handle.

The top red button switch will actuate the 
attachment in one direction.

The bottom red button switch will actuate the 
attachment in the opposite direction.

3. Switch couplers on the attachment’s hydraulic hoses 

if the hydraulic cylinder(s) operate in the opposite 

direction intended. 

4. Once hoses and cylinder(s) are full of hydraulic fluid, 

check tractor hydraulic fluid level.

5. If low, add recommended hydraulic fluid.

IMPORTANT:  

Refer to your tractor Operator’s 

Manual for recommended hydraulic fluid and 

procedure for checking hydraulic fluid level.

Relieve Hydraulic System Pressure

Be sure to lower the attachment to the ground and to 

relieve all hydraulic pressure to the attachment before 

leaving the tractor seat. Relieve hydraulic pressure to the 

attachment as follows: 
1. Turn tractor switch key to off. 
2. Press and hold both red buttons down on the control 

handle until all movement at the attachment stops.
