{{Introduction
|Introduction=<translate>Setting the pressure and clutch tension on the loading wheel is critical for the reliable and accurate running of the machine

If set incorrectly, the profile will slip and not load correctly or will not give an accurate start position for the datum holes


The goal is to set the system to a "goldilocks" zone where there is enough pressure and clutch tension to reliably load a bar, but not too much so the clutch limits any correctional movement from the gripper arm on loading

{{Warning|...It has been demonstrated that the clutch can easily untighten if the castellation is not done up correctly. The video demonstrates how easy it is for the wheel to become loose}}</translate>

{{Tuto Step
|Step_Title=<translate>Select a heavy profile for setting up</translate>
|Step_Content=<translate>Use the heaviest profile you can find - a full bar of door T or transom

Place it under the wheel so it can be fed into the machine

{{Warning|...Ensure the infeed flights are out of the way}}<br /></translate>
}}
{{Tuto Step
|Step_Title=<translate>Move the x axis clear</translate>
|Step_Content=<translate>Move the x axis to 4000mm so there is a clear test runway</translate>
}}
{{Tuto Step
|Step_Title=<translate>Check the profile can slide to the machine easily</translate>
|Step_Content=<translate>Ensure there are no height spots or differences in height between the infeed and outfeed table that prevent the smooth transition of the profile into the machine


Activate the side and top infeed clamps with the profile inside, check again that it slides easily  -the top and side clamps should be on 2 bar</translate>
}}
{{Tuto Step
|Step_Title=<translate>Activate the Wheel</translate>
|Step_Content=<translate>Ensure the top and side infeed clamps are off

Bring the wheel onto the profile</translate>
}}
{{Tuto Step
|Step_Title=<translate>Set the pressure</translate>
|Step_Content=<translate>Pressure should be set to 1 bar - any more than this creates too much drag for the clutch wheel to overcome

{{Info|...The wheel has considerable weight, it does not need much more from an additional cylinder}}</translate>
}}
{{Tuto Step
|Step_Title=<translate>Attempt to slide the profile by hand</translate>
|Step_Content=<translate>The wheel clutch tension should be set so you can still manually push the profile and out of the machine. The wheel should turn (ie should not not skid on the profile) but there should be obvious tension.


Adjust the clutch tension if to suit</translate>
}}
{{Tuto Step
|Step_Title=<translate>Try with power</translate>
|Step_Content=<translate>With the wheel on the profile, try the wheel motor on

The bar should drive in. 

If the clutch slips, turn motor off, tighten clutch, try again

<br /></translate>
}}
{{Tuto Step
|Step_Title=<translate>Try with power and infeed clamps on</translate>
|Step_Content=<translate>Try same test again with the infeed clamps on.

The clutch needs to just overcome the friction created by the side clamps</translate>
}}
{{Tuto Step
|Step_Title=<translate>Final manual test with motor off</translate>
|Step_Content=<translate>Now the clutch has been tightened to overcome the infeed clamp forces, see if you can still slide the bar with the wheel done and the infeed clamps on.

It should be more difficult, but it should be possible to overcome the forces.

{{Dont|...If you cannot overcome the forces manually, then there is something wrong}}

If this manual test fails, there could be one or more of these problems:

* Too much down pressure on wheel
* Clutch is too tight
* Friction / tightness in a roller
* A non-rolling part of the table or fence sticking out causing friction</translate>

{{Tuto Step
|Step_Title=<translate>Fold over the castellation locknut</translate>
|Step_Content=<translate>{{Warning|...This is a very important final step to prevent the clutch coming loose}}</translate>
