MAINTENANCE

Hydraulic Pressure Check

Following procedure outlines hydraulic pressure check.

1.

Obtain a pressure gauge that measures 3000 PSI in 50 PSI increments.

2.

Install gauge into the hydraulic line connecting the loader valve and to the base port bucket cylinders.

3.

Start engine and adjust to 1700-2200 RPM.

4.

Push bucket control lever to pressurize the hydraulic line with the gauge attached. Hold the control until the 
cylinders reach the fully extended position. Holding the control with cylinders fully extended will give you 
the hydraulic system pressure on the gauge.

5.

If pressure is not correct, refer to “TROUBLESHOOTING GUIDE” in the Operation Section for possible 
remedy, or contact your dealer.

Cylinder Service

Loader cylinders are designed to be reliable and easy to service. If a cylinder should malfunction during
warranty period, return complete cylinder assembly, without disassembling, to your authorized service
department or contact your authorized service department for instructions. Unauthorized disassembly of a
cylinder in warranty period will 

VOID WARRANTY
