How do I remove the original packaging from the fatmax


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.

How to open stanley fatmax knife 10-778 TO CHANGE THE BLADE. thank you


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.

Describe how you put a blade in FatMax model 10-778


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.

Change blades I just need a picture /instruction for blade change


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
