Brother KH840 cleaned and tested in September 2023

Brother KH840 knitting machine is a knitting machine capable of creating patterns using a punch-card-reading mechanism. The machine has 200 needles, spaced 4.5 mm apart, which makes Brother KH840 a standard machine. Read more about this model in my Knitting Machine Encyclopedia.

Now about this particular Brother KH840 machine. This Brother Knitting machine was cleaned, serviced and tested by me in September 2023.

Removed, inspected and cleaned all needles. The ones that were bent were replaced with the new stock. I replaced sponge in the retaining bar.

The carriage, sinker plate and then punchcard reader were cleaned, serviced and oiled.

I also knitted on the whole bed (using all 200 needles) to make sure all needles form nice and even stitches. I knitted the whole bed using tuck-, slip- and fair isle patterning. See a video I created of these tests. I did not test lace and weave capabilities of this machine. All levers and knobs move freely on lace carriage.

This machine comes with all major …(lace carriage, cast-on combs and extension rails)…

… and minor assesories.

All minor accessories fit into a built-in compartment. All major assesories fit into the case lid when now in use.

A couple of very minor assesories missing are:

• Bottle with oil (it was too old, and I had to discard it. I recommend using Gun Oil).
• Wax
• Cast-on thread (any silky and strong thread will work fine).
• Hard copy of the manual will not be provided but I can be downloaded online for free from here.

The machine comes with a set of punch cards but they might be slightly different from what is shown in the manual. Please, swatch before knitting for garments and knitted panels.

About imperfections:

Everything works great on this machine. The only minor flaw (with the exception of minor bumps on the case) is the small rust spots on the sinker plate and tension mast. They can be barely seen and when I used this machine to knit a cowl, there was no static and everything worked smoothly.

Overall I did not encounter any problems with this machine (with the exception of couple of minor scratches on the case). I hope you will be a proud owner of it to make a lots of fun and warm garments. Like the one I created (shown below) while testing this machine.
