Adjusting Manifold Relief Valves - Toro Greensmaster 3200 Service Manual

Adjusting Manifold Relief Valves (R1 and R2)
The hydraulic reel and lift circuits are equipped with re-
lief valves. These valves are preset at the factory to
2400 PSI (R1) and 150 PSI (R2), but an adjustment may
be required if the setting proves to be off after testing
(see TESTING). If an adjustment is required proceed as
follows:
Never adjust the relief valve with the
hydraulic system pressurized. Hydraulic
oil may spray out of the valve with the cap
off. Personal injury may result. Always
install the cap and tighten before pressur-
izing the system.
1. Remove cap from the relief valve with an allen
wrench.
Note: An 1/8–turn of the adjustment socket is about
50 psi (3.5 bar), or 1 turn is about 400 psi (27.6 bar).
2. To increase pressure setting, turn the adjustment
socket inside the valve 1/8 of a turn clockwise.
3. To decrease pressure setting, turn the adjustment
socket inside the valve 1/8 of a turn counterclockwise.
4. Install and tighten cap to valve. Retest pressure set-
ting (see Testing).
