g. Side Tilt Carriage Cylinder Pressure Checking

and Circuit Bleeding

1. Attach a 4,000 psi (276 bar) gauge to the test fitting

on the “VG” port of the unloader valve to test the
system pressure. Pressure readings should be

3,000 ±100 psi (207 ±7 bar). Refer to Section 8.7,
“Hydraulic System Testing.”
To check the cylinder
pressure, consult the factory.

2. Start with the side tilt carriage cylinder balanced:

that is, with the carriage level and centered, not
tilted.

3. Tilt the carriage fully left. Hold the joystick at full tilt

left for several seconds, then tilt the carriage fully
right and hold the joystick at full tilt right for several
seconds. Observe the readings on the gauge during
the carriage tilting operations.

4. Center and level the carriage. While levelling the

carriage, check the pressure reading on the gauge.

5. Repeat Steps 3-4 five times.
