Several of the hydraulic control manifolds on your Groundsmaster include

relief valves. Refer to the
information on testing relief pressure.

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.
