5 ROK Solid Ways to Make the Most of Your ROK Grinder

Just got a ROK Coffee Grinder and looking for ways to keep it in tip-top condition? You’ve come to the right place! This article will show you 5 easy ways to tweak and maintain your ROK manual grinder so that it’ll produce top quality grinds when you use it.

1. Static Grounds – The Super Easy Way to Deal With Them

This is a tip that I didn’t know before, and it’s my favorite because it’s applicable to all steel coffee grinders. If you’ve had a coffee grinder in the past, then you’ll know that static is a BIG issue. Instead of moving according to your will, static is where your grounds will stick to every surface it can find.

Coffee aficionados from Espresso Unplugged found a guide that teaches how to solve this problem once and for all.  This is also known as the Ross Droplet Technique.

As you can see, by just applying a one to two drops of water, the amount of static on the grinds drop dramatically.

2. Removing the Infinite Adjustment Washer

In my other guides and reviews, I mentioned the pros and cons in using step/stepless coffee grinders. In short, step grinders are easier to use and better for beginners. Stepless grinders are more suitable for the experienced to tweak the grinds specifically to their tastes.

Well, ROKEspressoMaker from YouTube shows us how it’s done of this ROK Grinder:

Basically, you just turn the adjustment wheel clockwise until it comes off, remove the 2 washers, and just put things back together in this precise order – spring, burr, burr key, and adjustment wheel.

One of the best manual coffee grinders in the market and perfect for Espresso-Lovers!

NOTE: lots of bits will fall off when you remove the adjustment wheel from the thread, be prepared!

Through this, when you make future adjustments, you’ll be able to feel and hear the clicks happening. If you’re a beginner, this will help!

3. Fixing that Annoying Squeak!

In my ROK Coffee Grinder review, I’ve mentioned that some users experience squeaky noises when using it. I looked into this further and found that ROK Kitchen, the manufacturer addressed the issue.

They said if you ever hear these squeaky noises, simply apply some food-grade lubricants (such as olive oil) on the bevel gears, and you’re good to go. Sounds straight forward? It is!

4. How to Check the Outer Fixed Burrs

When you use the ROK Manual Grinder for the first time, the burrs will be closed – you can tell if the handle is hard to turn.

To set it up, all you have to do is loosen the adjustment wheel (clockwise), and the conical burrs will loosen with it. Afterwards, just turn the handle clockwise and anticlockwise with beans inside, and it will align itself.

5. How to Recalibrate the Adjustment Wheel

After using the ROK Espresso Grinder for a while, like many other grinders, the adjustments could misalign. Luckily, this is a known issue for the manufacturer, and once again, they released a video on what to do:

Assuming you’ve watched the video already, all you need is a hammer and nail, and just do the following:

  • Find the pin on the bevel gears that aligns it together with the crank handle.
  • Remove the pin by placing the nail on top of it and hitting it gently with a hammer.
  • Remove the crank handle by pulling it sideways – be sure to keep the bevel gears and pin safe, they’re important!
  • Whilst the burrs are closed, turn the adjustment wheel until the no.1 sign aligns with the line.
  • Align the pin holes and put the crank handle + bevel gears back together.
  • Using the hammer and nail, put the pin back in place and you’re all done!

If you haven’t figured it out yet, this is the HARDEST tip of the 5!
