Before you start
Before starting any work, check that the machine is firmly fixed to the wall or freestanding leg.
Select which of the four situations below best matches your clamp issue, then scroll down to the relevant section. If you are not sure what your issue is, please start at the top and work through each section to diagnose.
Clamp will not fully close
If the clamp will not fully close, the first thing to check is the clamp bar is correctly positioned and not moved off its internal guides. This solves the issue 90% of the time. Check my clamp bar is in place > If your clamp is still not closing, there may be a part worn in the clamp housing or within the clamp itself. Please refer to step number 3: Clamp pressure too low.
Clamp does not close fully along the length
If your clamp is partially out of alignment either at the top or bottom, it may require adjustment to re-align. Follow our guide on How to adjust the SteelTrak clamp alignment > If you are stilll finding the clamp is not fully closing in the middle please refer to step number 2: Clamp not fully closing in the middle.
Due to aluminium tolerances, there may be a small gap between the middle of the clamp and the spine when it is closed and touching at the top and the bottom. The design of the clamping system takes this into account and will not affect its clamping ability. If the gap is more than 1-2 mm check the following:
There could be a number of reasons the clamp seems to have reduced pressure compared to normal. Follow the steps below to find out what could be causing this in your machine.
