REPLACE THE POWER CORD ON AN ONFLOOR OF16S EZV SANDER

The power cord may be wired multiple ways. We are going to show you how to replace the power cord for two possible wiring methods.

Do not attempt to service your machine if the wiring on your sander differs from the two ways we are demonstrating in this video.

Warning, the power cord should not be used with an additional extension cord. Before we start, please make sure the machine is not plugged into the power source. Utilize the lockout tagout procedure and refer to the EZV manual.

 

remove the middle switch plate

Start by removing the middle switch plate on the back of the sander handle using the number two Phillips head screwdriver, or a drill with a number two screw head.

Wiring method 1

 

remove electrical tape and wire nut

Remove the electrical tape and the wire nut from the three white lead wires and separate them.

Power-Cord-Onfloor-OF16SEZV-Sander-remove-electrical-tape-wire-nut

 

remove lock nuts

Use the 3/8th of an inch nut driver or wrench to remove the lock nuts that secure the three green ground wires to the handle. You may need to use a Phillips head screwdriver to secure the bolt on the front of the handle.

There will be two nuts to remove between the three green ground wires. Be sure to hold on to them for later.

Now, you should see three white lead wires and three green ground wires.

 

Remove the lock nut that holds the switch

Next, go to the front of the machine's handle, use the 9/16th inch nut driver or deep socket wrench to remove the lock nut that holds the switch onto the handle.

remove switch from handle

Go to the backside of the handle again and remove this switch from the handle. Take care not to lose the plastic white spacer attached to the switch.

unscrew the holder ring

Unscrew the holder ring from the power cord and pull the power cord up enough to remove the rubber cord grommet and any electrical tape. Take care not to lose this rubber grommet as you will need it for the new cord.

pull-out old cord and insert new cord

Now, pull the cord completely out of the handle. Insert the new power cord wires in through the handle and pull the cord up to create some extra slack.

Reattach the power cord

Reattach the power cord wire back onto the switch. Again, that's the black wire with the yellow terminal. Please note that as you are connecting the wire, the switch should be upside down with the off position at the top.

Re-install the switch and white spacer

Re-install the switch and white spacer to the handle using the 9/16th inch nut driver or wrench to reattach the lock nut that holds the switch onto the front of the sander handle.

Now, reattach the three green ground wires, securing them with the lock nuts that were removed earlier.

 

 

wiring method 2

As mentioned earlier in this article, there are two possible ways that your machine could be wired. Here's wiring method two. This is the second most commonly used method of wiring.

 

remove wire nut and electrical tape

If you see a small black jumper wire connected to the switch, remove this wire nut and electrical tape.

disconnect wire from switch

Then you will disconnect this wire from the switch and discard it.

Now, just connect the new power cord directly to the switch as shown in method one.

 

 

reattach switch plate

Now, you can replace the middle switch plate cover and reattach it with the hardware back onto the sander's handle.

Now that you're done, be sure to test that the toggle switches work properly and that they match their labeled functions.
