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.

Remove cap from the relief valve with an allen
wrench.
