IMPORTANT: When performing this test, do not
hold over relief any longer than necessary to obtain
pressure reading.

Watch pressure gauge carefully while slowly closing
Before opening hydraulic system, operate all hy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving Hydraulic System Pressure in the Gen-
eral Information section of this chapter.
12.As
the relief valve lifts, system pressure should be:
From 2450 to 2600 PSI (169 to 179 bar) for relief
valve (R1)
4.
Raise and prop operator seat to allow access to hy-
draulic mow control manifold.
From 3450 to 3600 PSI (238 to 248 bar) for relief
valve (R2)
5.
Set reel speed controls (FC1 and FC2) to full open
(highest number). Make sure backlap levers are posi-
tioned in the mow position.

pressure is incorrect, remove solenoid valve on
reel motor fitting on left side cutting unit for the relief
valve to be tested. Disconnect hose from reel motor fit-

mow manifold and clean or replace valve (see Mow
Control Manifold Service in the Service and Repairs
section of this chapter). Also, if pressure is still low after
solenoid valve service, check for restriction in pump in-
take line. Gear pump (P2) (front cutting unit circuit) and/
or pump (P1) (rear cutting unit circuit) could also be
suspected of wear, damage or inefficiency (see Gear
Pump (P1) and (P2) Flow Test in this section).

Left front cutting unit (#4) for relief valve (R2)
IMPORTANT: Make sure that the oil flow indicator
arrow on the flow meter is showing that the oil will
flowfromthedisconnected hose,through thetester
and into the reel motor.
15.After
testing is completed, make sure that engine is
stopped, then relieve hydraulic system pressure (See
Relieving Hydraulic System Pressure in the General In-
formation section of this chapter). Remove tester from
machine and connect hydraulic hose to reel motor fit-
ting.

Install tester with pressure gauges and flow meter in
series with the disconnected hose and hydraulic fitting
on reel motor. Make sure the flow control valve on
tester is fully open.

nections and correct before proceeding with test.
After installing tester, start engine and run at idle
