Procedure for Reel Circuit Pressure
Test:
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately 10
minutes.
2. Park machine on a level surface with the cutting units
lowered and off. Make sure engine is off and the parking
brake is engaged.
3. Read Precautions for Hydraulic Testing.
WARNING
Before disconnecting or performing any work
on the hydraulic system, all pressure in the
system must be relieved. See Relieving Hy-
draulic System Pressure in the General Infor-
mation section.
4. Remove plug from hydraulic manifold test port (G1).
5. Install pressure test gauge with hydraulic hose at-
tached into the test port.
6. Make sure backlap knob on the hydraulic manifold is
in the mow position. Make sure reel speed knob is set
for typical mowing conditions.
CAUTION
Keep away from reels during test to prevent per-
sonal injury from the rotating reel blades.
7. Start engine and move throttle to full speed (2650 +
50 RPM). Engage the cutting units.
8. Watch pressure gauge carefully while mowing with
the machine.
9. Reel circuit pressure should be about 600 PSI.
10.Disengage cutting units. Shut off engine.
11.Disconnect test gauge with hose from manifold
block. Reconnect plug to the hydraulic manifold test port
