Dynamax HPFM3, Installation And Operation Manual, Page: 63 / 86

II. For sizes from 20mm to 50mm, leave 5-10mm of root stem above the top of the rubber compression seal.
Note:
Check the distance below the rubber compression seal. Can you see leaks? Can
you perform the installation of the coupling easily?
c. Cut or excise with a smooth level cut. The cut should always be perpendicular to the stem.
d. Use a razor blade (included with the HPFM) to remove the bark and related material to the depth of
the cambium.
3. After having cut and prepared the stem, slip the nut and aluminum compression ring over the root stem. Make sure
that the washer is as close to the size of the stem as possible. The aluminum compression ring should still be
easy to slip on or off.
4. Place the rubber seal over the prepared area of the root stem. The seal should be snug, but should not have to be
forced. If the compression seal is too small, use the next largest seal. If the rubber seal is too big, use a smaller one. The
rubber seal should be applied with out a lubricant onto the sample and should have some light to moderate friction when
twisted. Approx. 1cm of stem should be protruding from above rubber seal as shown in Photo 10. If not,go back to step
2 and remove more bark.
WARNING!
BE CAREFUL with Knives, Razor Blades, Saws and other TOOLS.
