Adjust Control Manifold Relief Valves

The hydraulic control manifolds on your Reelmaster in-
clude the following adjustable relief valves:
All machines − Mow control manifold relief valve RV
should be set to 1500 PSI (103 Bar).
Reelmaster 3550−D − Lift control manifold relief
valve RV1 should be set to 500 PSI (34.5 Bar).
Reelmaster 3555−D and 3575−D − Lift control man-
ifold relief valve RV1 should be set to 2000 PSI (138
Bar). Lift control manifold relief valve RV2 should be
set to 500 PSI (34.5 Bar).
Adjust the relief valves to the recommended settings as
necessary.
NOTE: Do not remove relief valve from the hydraulic
manifold for adjustment.
1. Locate relief valve on control manifold.
2. Remove cap on relief valve with an allen wrench.
3. To increase pressure setting, turn the adjustment
socket on the valve in a clockwise direction. A 1/8 turn
on the socket will make a measurable change in relief
pressure.
4. To decrease pressure setting, turn the adjustment
socket on the valve in a counterclockwise direction. A
1/8 turn on the socket will make a measurable change
in relief pressure.
5. Install and tighten cap on relief valve.
6. Recheck relief pressure and readjust as needed.
