Hi Ya'll ,

I really need some help, LOL ...My manual for my US Cutter MH 871-MK2 has disappeared and I can't figure out how to fix the issue of the needle cutting all the way through my vinyl,

and I also can't remember how to adjust the pressure on the guide wheels either. PLEASE HELP ME!!!

Thanks in advance.

WHOA!!!  Grammy, you do need some help!

You can do a quick search for 'adjusting the blade' and more than a few posts by MzSkeeter will pop up.

The pressure on those guide wheels should not be messed-with (in general), but if you are having tracking issues, the best bet is to back the knurled brass knobs all the way out so they are all matched to the top of the screws, and then give 'em all two turns down, see if that corrects your problem with the vinyl going through.
(Keep in mind that your vinyl will show the pressure marks as it feeds, but when you apply the material, those 'track marks' will vanish).

One more point here ---  since you've had problems with the blade going through the backing, check to make sure the silicon (white) cutting strip is not gouged or torn from the needle passing over it with that much pressure. If there is serious damage to that strip, you may need to replace it.

Slice & Dice,

Thank you so much, I will do a search for MzSkeeter's posts.

Grammy, here is the place to obtain the 34" cutting strip
https://uscutter.com/uscutter-mh-vinyl-cutter-replacement-parts/

Select drop-down menu to choose the required part -- it just costs $17    -- however, keep in mind that shipping is a flat rate $12, so you are highly encouraged to add more items to your order, up to 70 pounds total, to defray that shipping cost over several products, such as vinyl, app tape, banners, coroplast blanks, tools & supplies, etc.

Let us know how things go, and post any advice or information so that others may follow your solution and it may help them in the future.

To start with, you should set your blade depth correctly, by taking the blade holder out of the machine, and firmly cut across a piece of scrap vinyl, you will be cutting. You should only be cutting the vinyl and barely a mark on wax paper backing, Adjust blade to get there, Then put the blade holder back in machine, and use the force of the machine to get there, same results, only cutting the vinyl and barely a mark in wax paper backing. You should barely see and feel the blade tip out of the blade holder. Regular sign vinyl is only 2-3 mil thick. You only cut with the very tip of the blade. When you think the blade is so far in the blade holder, that you think it would not even cut, that is probably correct.
