Is Full Boar mitre saw motor arcing normal?

G'day Bunnings Team.

I purchased the Full Boar 305mm (FBSCMSDB-20305) sliding compound mitre saw yesterday afternoon from Bunnings, which was on clearance.

I was late setting it up and it was getting dark at around 1900hrs before I finally turned it on.

The electric arcing was like the 4th of July.

New brushes of course, but I've never seen anything like it on a powered tool before.

It is so bright it 'shines' through the plastic motor housing and is more prominent when the switch is released.

I thought after a few goes the brushes might settle down - but no.

I tried again earlier this morning.

Before...

After...

Note the crimson colour, it's not a photo abnormality - that's the arcing shining 'through' the plastic.

Can this be normal?

Cheers.

Hi @Noyade,

As you know, seeing sparks through the grill is quite normal for a brushed tool, and until they bed in, the sparks can be more noticeable. However, being very familiar with tools, just the fact that you've noticed that the sparks seem more prominent than what you'd typically expect concerns me. What you're explaining sounds more like when a brush has completely worn through, and the metal retainer or spring for the brush is contacting the motor.

In the interest of safety, I feel it would be best to return the tool and exchange it for another if there are any left or receive a refund. If the next one does the same, I'd be happy for you to continue using it.

Given that this is a bit of an odd one, I'll contact the store and let them know you'll be coming in to swap it over. I'll reach out via PM for more details.

Please let me know if you have any questions.
