Loading instruction to change blade on Stanley FatMax box cutter

You have to loosen, NOT remove, two bolts on the blade cover so it rotates just enough to give you access to the spindle bolt holding the blade on. Check this web page for the user manual. You'll need the pictures on page 5 and the description on page 14 of this manual.

Question edited to fix spelling.

I agree. The packaging is ridiculous.
I removed it by grasping the packaging and pulling (very hard) from the blade end (bottom left as looking at it) straight out. This stretched and tore the plastic "paper" and pull the knife free.

Push the blade out as far as it will go and hold in the button on the side while slideing blade in and out.

How do I change the blade on the quick change/instant change knife? Warning: Blades are sharp and can cause serious injury. Be extremely careful when handling blades. Wear eye protection and dispose of used blades properly, such as wrapping in duct tape.


FULLY EXTEND THE BLADE.
Press down and forward again on the slide button until the button is in the full front of the top slot (0 through 3 in the below picture).

Note- the blade must be extended beyond the 3rd detent position. This will cause the slide button to remain in a down position, allowing the blade release button to operate.

PRESS AND HOLD THE BLADE RELEASE BUTTON ON THE FRONT SIDE OF THE KNIFE. (Step 4 in the below picture)

Note- if the blade is not fully extended beyond position 3) , the blade release button will not work.

Remove the old blade carefully.
Insert new blade.

NOW, RELEASE THE BLADE RELEASE BUTTON.
ENSURE THE BLADE IS LOCKED IN PLACE. If the blade does not retract, try carefully giving a slight tug on the blade to reseat.

at the handel end it will pull apartthen slide the whats left of the old blade and put new won in its place just do it slowly so you dont forget how it goes

On the side there is a big gold wheel, twist counter clockwise and the case should split in half, the blade is held by a magnet, prise the old blade off and replace with new one, then put case back together and tighten gold wheel clockwise
Goodluck!

The model in your picture is a fixed blade utility knife (model 10-816). Your question asks for instructions for model 10-778, which is a retractable knife. I'll guide you through the 10-778 which you asked for, if you need instructions for the pictured 10-816 please re-post the question.

Push the thumb slide forward as far as it goes exposing the blade. Press the blade change button on the side of the knife (the small button on the left side near the blade) and pull out the old blade.
Insert the new blade and slide thumb slide back to fully engage blade in the internal lock.

The gold looking circle on the side of the utility knife. Just unscrew that and it will pop open then you can change the blade. I looked everywhere and am unable to find the instruction or picture. I own one and that is why I am answering this for you. Please rate
