Master 5335B Heavy-Duty 3-Hole Punch by Martin Yale

This is the Master 5335B Heavy Duty 3 Hole Punch!

Before using, first adjust the edge guide to your paper size. I’ll set mine to 11 inches. There is an arrow that you line it up to.

Okay, now we can insert our pages. Now the product description says it can punch 32 sheets at a time, but a more realistic number is 20 sheets at a time.

With 11/32” holes they are slightly larger than your standard hole punches.

To change the punch heads, first unscrew the back screw. You’ll probably find that you have to open the catch tray to further unscrew the nut on the bottom. This will release the screw and the backstop.

Now pop off this little metal ring from the end. And I will say this probably won’t be easy—with this hole punch this entire process can get annoying and take a decent amount of time.

But now wiggle out the lever rod from the punch heads. Since I only unscrewed the end one that is the only one I will be freeing up for this demonstration. It comes right off now.

To put it back on, or a new one on, hook it into the front end of the punch, then proceed to wiggle the rod back in. But you will have to push the top down so it lines up with the crevasse in the rod.

Then screw everything back on, and pop the little metal ring back in place—and you’re done.
