Need a new shiny button? You’ve come to the right place! Here you will learn how to replace an old-style lock nut Start Button with the new contact block style on your cold press juicer. (These instructions apply to the Stop buttons too!)
Before You Start
Before getting started on replacing your start button (see what we did there?)…
SAFETY FIRST! Always remember to make sure to turn your power off before working on any type of electrical maintenance or even cleaning. Always unplug your machine when servicing or cleaning also.
You can turn off the main power with the red and yellow switch on the electrical box located at the back of your press.
Powers off? Machine unplugged? Good, now let’s get started.
Replace Your Button

The button is in the Control Panel, which is located next to the shredder. The Control Panel is the front/top portion of the Control Box, which houses all your buttons and switches for operating the machine.
To replace your button, follow these steps:
Remove the Old Button

- Loosen the two screws holding down the terminal wires

- Then, remove the wires and remove the Lock Nut at the base of the button

- Toss your old button (safely, of course, don’t conk anyone on the head)
Install the New Button
- Now grab your new Button

Note: the new style buttons use a contact block holder on the back to hold them in place instead of the lock screw

- Put the button through the hole in the front of the control panel

- Line up the arrows on the contact block with the arrows on the button º there are also grooves that match up in these same locations (see image below)

- Then place the contact block holder onto the installed button on the inside of the panel (see finished installation in image below) – when you install the contact block holder it’ll make a nice little click – that’s how you know it’s in

- Tighten the screw used to hold the contact block holder down – this screw secures your button into place

- Grab your Contact Block

- Check the top of your contact block and make sure the number Four (4) is at the top and the number Three (3) is at the bottom (you can see them in the above image at the side of the contact connections or on the contact side, they’re really tiny and would be upside down to you!)

- Hook the top of the contact block into the holder to the left side of the button back
- Push down on the bottom of the contact block with one finger and just a little bit of pressure (and maybe just a little wiggle) until you hear a click – that’s how you know it’s secured

- Now that our new button and contact block are properly secured, you will install those wires that you took out before
- Your Number One (1) Wire will be going into the Number Four (4) Terminal, then tighten the screw to hold it secure

- Your Number Three (3) Communication Wire will be going into the Number Three (3) Terminal, then tighten the screw to hold it secure

- And with that, your button and wires are secured and you’ve done it – Good Job!

Finish Up
- Tuck all the wires and close the control panel carefully
- Use a large flat screwdriver to “lock” the box and apply pressure to the seal
- Plug in and turn on your machine to test your new start button!
