Adjust Manifold Relief Valve (R1) - Toro Reelmaster 3100-D Service Manual

Adjust Manifold Relief Valve (R1)

The hydraulic reel circuit is equipped with a relief valve.
This valve is preset at the factory to 3000 PSI. However,
an adjustment may be required if the setting proves to
be incorrect after testing (see TESTING). If an adjust-
ment is required proceed as follows:
WARNING
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
pressurizing the system.
NOTE: Do not remove the relief valve from the hydrau-
lic manifold for adjustment.
1. Remove cap from the relief valve with an allen
wrench.
NOTE: A 1/8−turn of the adjustment socket will make a
measurable change in relief pressure.
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).
