Most importantly, you need a snug fitting adapter on the post. This ensures the machine is level on the post, striking it hard in the post centre, every time.

If you are installing multiple sizes of post, then you will need a few different adapters.

Adapter size guideline:allow 5-10mm larger than the post diameter. For non-uniform post shapes, measure the widest diameter of your post.

A poorly fitting adapter will be a detriment to the machines performance, and will cause strain on the operator and the machine.
