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 hoses (#9) at
couplers (#11) if the attachment’s 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.
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.
Press and hold both red buttons down on the control
handle until all movement at the attachment stops.
IMPORTANT:
Refer to your tractor Operator’s
Manual for recommended hydraulic fluid and
procedure for checking hydraulic fluid level.
