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:
