Milwaukee Trigger Safety Issue

[jhendric]

Folks, I have posted and read many posts regarding Milwaukee's trigger challenges. This weekend I was cutting cement fiberboard siding and had a scary problem. The trigger on my Milwaukee Circular saw was sticking in the "on" position after I release d the trigger. As I was using a cement board blade (the type that is more like a grinder wheel than a blade with teeth) I kept going with it, but it stuck 3x. A quick tap on the trigger released it, but man that's no good.

Has anyone else experienced this? I would think that's grounds for a recall.

What's the model number?

Are you left-handed?

Since all is made over seas, I dont think it matters anymore. One reason I started buying little more from HF. I do own few Milwaukee M18 fuel but I won’t buy again

I had mine repaired at an authorized repair facility. It took a few months but I was traveling and did not need it. Have not had any problems since. I did replace the trigger myself, same ****, did not work. Use the repair shops. It's easier.

Could it be caused by build up of cement board dust within trigger/handle? Maybe shoot some electronics cleaner to clean it out?

I can see how cement fiber board would wreak havoc on an electrical tool.

The dust buildup is probably preventing the trigger from releasing.

Is this an older Milwaukee corded circular saw, or a newer cordless one?
There was a wide power tool industry recall at one point for a certain type of power tool switch made by Eaton, that was used in a ridiculous number of tool models back in 2001, but tools sometimes remain in use for decades.

CPSC, Power Tool Manufacturers Announce Recall of Various Power Tools

Consumers should stop using these power tools immediately and contact the tool manufacturer to receive a free replacement tool or tool repair.

www.cpsc.gov

Otherwise, dust (and wood splinters), can sometimes jamb power tools in the on position.

A few follow ups, The tool is battery powered and about 4 years old. I hear you on the dust being a problem, but still, cement fiber board is one of the things that need cutting with a circular saw.

Fiber cement board dust clogs everything. You need to blow your tools off at least once a day, preferably more.

More importantly I hope OP is wearing an appropriate respirator that silica dust is bad news for your lungs.

Good point!

For sure on the respiration filter, I overkill any time I create dust nowadays, 3m half face with particulate and organic filters stacked. I find that the 3m is only slightly less of a pain than a "covid" n95 mask.

Typical operating procedure in this case would be to blow out dust from the tool every day

This a particularly bad environment for tools, not even sure Metabo makes a cordless circ saw up to this task

The switch should never stick in the on position. Milwaukee is not my tool of choice for other quality issues, but this is something that should never happen.

Cut fiber cement siding with electronic siding shears, not a saw.

I think Makita might though, they definitely did a corded masonry circular saw

Yes they do

DCC501 - Cutter LXT®

There's also a dry version you can hook up to a dust extractor
Both would be good for cement board

I have sided houses and broke down numerous sheets for other jobs which involved making hundreds of cuts with both cordless and corded circular saws and miter saws using polycrystalline blades. Never once has a trigger stuck or any other malfunction happened due to dust.

This saw has a problem beyond dust intrusion.

Ive had intermittent trigger issues caused by dust on an M18 Surge impact driver. Opened it up and blew it out problem solved. I don't recall if I sprayed any kind of contact cleaner in it or not but I may have.

Here's a video (not mine) with this issue so apparently sometimes happens.

This is likely the last siding project I will involve myself in. If I were to do more I would consider the shears.
