Adjust Manifold Relief Valve (R1 and R2)

The hydraulic reel circuit is equipped with a relief valve.
Valve (R1) is preset at the factory to 3000 PSI. Valve
(R2) on Reelmaster 6500--D is set to 2000 PSI. Valve
(R2) on Reelmaster 6700--D is set to 3000 PSI. Howev-
er, an adjustment may be required if the setting proves
to be off after testing (see TESTING). If an adjustment
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 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 adjust-
ment socket inside the valve 1/8 of a turn counterclock-
wise.
