Before manifold mounting the pull cylinder, remove
the port screw plugs and copper gaskets or o-rings.
Prior to mounting and bolting down the pull cylinder,
lubricate the o-rings provided and install them in the
counter-bore around the port.
Be sure that the o-ring does not get pinched or
damaged during mounting as leakage could result. To
prevent leakage from the manifold mounting, provide
a fixture mounting surface with flatness within 0.08
mm (0.003 in.) and a surface roughness not to exceed
Ra 1,6.
