How to fix Ozito 36V battery lawnmower that won't start?

Hi there, 

my 36v Ozito battery powered lawn mower will not start. 

2x 18v batteries are new and fully charged.

1x after pin is all the way in. 
2x battery connection points are clean

1x blade is free from clippings and rotates freely.

 

pushing the button on the handle and lifting the leaver to engage and start does not work. And the lawn mower will not start.

 

thoughts? Advice? Will Ozito replace?

 

thanks in advance?

Hello @antoine 

 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your Ozito lawnmower.

 

If your lawnmower is still within the 5-year warranty period, I suggest bringing it to the store along with your proof of purchase. If you purchased it with a card, I recommend trying to track down your purchase through your bank statements or perhaps your PowerPass account if you have one. I'm afraid there are no serviceable parts inside the mower and the batteries are sealed units and can't be repaired in a conventional manner.

 

If you have any other questions we can help with, please let us know.

 

Eric

Here is a repair tip for cordless garden tools (and maybe even mowers).

While you were using the tool did it suddenly stop working?

I often find myself repairing stuff for people, usually family and friends but sometimes for people I don't even know.

One of the common faults I have come across is caused by - vibration.

Here is a Bunnings XU1 grass trimmer that was left in my workshop with a note - stopped working please fix.

Cordless tools like this are difficult to pull apart and a nightmare to reassemble.

As expected one of the motor connections has come adrift - caused by vibration.

What is that coil thing and why the capacitor ?
This type of DC motor is very noisy so some sort of EMI suppression (element filter) is required, in this case a inductor and ceramic capacitor on each motor terminal. Enamelled copper wire doesn't cope well with vibration (from the motor) and will fatigue over time.

Managed to tin what was left and soldered the connection. Then pushed the heat shrink firmly down all the way and did the cig lighter thing.

Finally wrapped both connections with rescue tape to further absorb vibrations. The capacitor with a broken leg went into the bin.

 

Cheers
