The G35, G70 and G75 riser seal assemblies and the compressed retraction spring are retained on the risers with the
rubberized logo cap assembly. It is necessary to remove the rubberized logo cap assembly in order to replace the
riser seal assembly. To remove the rubberized logo cap assembly, it is necessary to fully compress the riser spring by
grabbing the riser seal assembly (g 43), pressing downward and then holding riser rmly to prevent the spring from
moving upwards.
Caution! The riser assembly is under spring tension. Eye protection should be worn and safe-handling
procedures followed when servicing this product.
Hold the riser seal assembly down with one hand. Using the other hand, locate the two hidden screws that retain the
rubberized logo cap assembly. These can be found by pressing down on the rubberized logo cap close to the “H”
and the “r” on the Hunter logo (gs 44 & 45). The Phillips headed retaining screws are directly beneath these
depressions. Insert the Phillips screwdriver through the rubberized membrane and engage each retaining screw. Turn
counter-clockwise to remove each screw.
Prior to removing the rubberized logo cap assembly, note its orientation as it relates to the nozzles below. This will
help with the assembly process later. Remove the rubberized logo cap and set aside.
While still holding the compressed riser seal assembly and retraction spring with one hand, use the other hand
to grasp the bottom of the riser assembly. Slowly release the compression of the retraction spring until it is fully
extended and no pressure is felt.
Prior to removing the riser seal assembly, note the orientation and sequence of the three individual seal assembly
parts (g 46). The Upper Seal Support is on top and its lower surface nests perfectly with the top of the riser seal. The
Riser Seal is the rubberized part in the middle. The Lower Seal Support (also known as the Upper Spring Support) has
an upper surface that nests perfectly to the lower surface of the Riser Seal. The Support’s lower surface also provides
a nest for the retraction spring. During assembly, these three parts must keep this sequence and orientation in order
for the seal assembly to function properly.
If any one of the three parts in the seal assembly needs replacement, it is highly recommended that all three
components be replaced. To re-assembly the riser, place the seal assembly on top of the retraction spring and then
compress. While rmly holding the retraction spring and seal assembly down, place the logo cap assembly on top
of the riser in the correct orientation. Insert the two stainless-steel screws through the rubberized membranes on the
logo cap and hand tighten with a Phillips screwdriver.
