How to Replace a Lawnmower Switch - Bosch

When you’re finding it a little difficult to start your lawnmower you could possibly have an issue with the on/off switch.

This guide has been created to help talk you through just how simple it is to replace this crucial part. Understanding what is involved, and then performing the replacement yourself, will help you save money - as the only other options would be to pay for it to be fixed or for it to be scrapped.

So instead of considering the money wasting alternatives, just take a look at this handy guide and give the repair a go yourself.

This video shows an example on how to remove or replace the part on a typical machine, some models may be different but the procedure should be similar.

  What You Will Need:

  Step 1 - Safety Advice

Safety First! Please ensure that you have disconnected the appliance from the mains before starting any repair.

  Step 2 –Removing the Housing

To start we first need to remove the switch housing from the handle and to do this you simply need to unscrew the two screws at the bottom.

Once removed you should be able to pull the bottom piece off and this will then allow you to remove the housing from the handle - all before twisting it 90° to remove it from the control bar.

  Step 3 – Finding the Switch

With the switchbox now removed there will be another set of screws that hold the housing together. Removing these screws will unveil the internal on/off switch and the cables. Now because you’ll need to replace the wires, it is recommended to take a photo of the current wiring arrangement for reference - for when you have to rewire the switch later.

  Step 4 – Removing the Wires

The cables are attached on either side of the switch, these are held in place by push fit connections which are tightly held in place by small barbs inside the switch. We recommend using a pair of pliers to carefully pull the wires (ensuring not to damage them)

However don’t fret because if they do become damaged then you can always strip some of the wire back before refitting them back into the switch.

  Step 5 – Replacement and Re-assembly

With the wires removed from the old switch you just need to replace them with the new one, before you start to refit the wires just give each one a little pull to make sure that they are secured in place.

Once you're happy you can put the switch housing back together and then fit it back onto the handle.

You’ve just replaced the on/off switch on your Bosch lawnmower, many people would consider a new appliance over performing the repair themselves. For other lawnmower repairs which you can do yourself, don’t forget to check out our other advice articles.
