Change the Yarn Guide

For the KRDI, the yarn guide needs to be adjusted before use. Please consult either of the videos below to see how to adjust it:

For a straight guide

 

For a bended guide

 Cut to loop

 For changing from cut to loop there are 2 methods. One simple method and one advanced method. The advanced method allows for more specific pileheight changes and changing the needle might help you save a little yarn. This method is more used in the carpet industry and the simple method will likely fit your needs.

Cut to loop simple method

this is a super easy way to switch from cut to loop. although not optimal in making really straight lines and saving yarn it will be good enough for most people. you will turn the scissors into a loophead by removing the part that makes the scissors close, in other words keeping it in open state at all times.

Unscrewing parts to take out the needle holder

Written manual

 Please note: since may 2021 the KRDI has a generic needle for both cut and loop. This part no longer needs to be changed. Therefore you can now remove the scissors and replace it with the loophead without having to remove the foot and handle. Like in the video below:

 

Maintenance and lubrication

Please make sure the rails over which the block moves back and forward are properly lubricated so no frictional resistance arises.

 

 

 

Changing the height of the cut pile

The basic concept

The distance between the point where the scissors close and the canvasspring is  same lenght as the pile. The distance between that same canvasspring and the eye of the needle should be the same plus 2 mm. 

example: the pileheight you want is 15 mm. make sure the distance from the closing point to the canvasspring is 15 mm. make sure the distance from the canvas spring to the eye of the needle is 17mm.

In any changes we make to the pileheight, we should always make sure that these distances stay equal plus 2 mm.

So as the image below it is a 3-point adjustment of the AB distance and the BC distance where AB is almost equal but slightly shorter than BC. AB is the pileheight and BC is the adjustment for the rest of the machine.

A= cutting point

B = canvasspring

C = eye of the needle

This method for changing the pileheight is the least error prone and requires the least changes to the gun. Always make sure you plug out your gun. You can hurt yourself if you accidentily turn it on while doing the changes.

1.
The first step is to loosen the canvasspring to change the distance between the canvasspring and the scissors closing point. Unscrew the screw at the bottom, bring the relative distance of the wanted pileheight to the closing point of the scissors and tighten the screw.

2.
Secondly we need to bring the the same distance between the needle eye and the canvasspring plus the 2 mm. This we can do by changing the lentgh of the bottom arm which holds the canvasspring and scissors in the bottom sliding part. Release this arm by taking of the the front bold. You can now slide the botom part to the wanted position. Rotate the arm to change the length and lock the desired distance between the needle eye and the canvasspring. Put the arm back in place.

3.
After making these changes the position of the scissors has changed but not the position of the accessories that make the scissors open and close. Depending on if you made the pileheight shorter or longer, you need to check these accessories and wether they do their job right.

Do a running check. If you bring the scissors all the way to the front, they should close at the final point. If they do not close, or close too soon, move the position of the scissorcloser to a position where it does close at the right point.

 

Bring the scissors to the back, they should now open. If they do not open, move the scissors opener to a position where it does cause the scissors to open.

 Position of the foot

The position of the foot must always be like this:

With the needle in the heighest position, the foot must be just below the eye of the needle as where the bottom of the needle-eye  is touching the line of the foot.

Trouble shooting

Scissors not closing

There is a part on the foot that determines where the scissors close. You will need to loosen the little black  screw that holds the sliding part in place. 
When you have your scissors in the highest position, where they now stay open; Use a tool to move the sliding part to the exact point where the it makes the scissors close and fasten it there.
