Makita Drill Keeps Sticking

[Jupiter01]

I have owned one of these for the last 3 years but not used too extensively. Unfortunately, it's developed a fault where the trigger button sticks when fully pressed. It either needs to be pulled out or most commonly, I remove the battery to bring it to a halt

Can someone please suggest a fix?

Thanks in advance.

 

[EddieM]

Yep, but a proper blue one.

 

[Jupiter01]

sorry, @EddieM. I didn't understand your response.

I think it was an attempt at humour that failed (not helped by a typo)

I'd start with some silicone spray. Often frees up these sort of things. Easy to try and won't hurt. After that you are into opening it up. The switch can buy bought separately and is pretty easy to replace if all else fails. They can be little fiddly to put back together without pinching a wire but its an easy diy job.

Thanks @nickjb. That's very helpful.
I've since had a scour of the net and Youtube and it appears that I need part number 650731-7 and this costs around £30. It seems reasonably straight forward to replace.

However, is this a good choice of action given that a new drill seems to cost £43.99

I assume I get a new warranty with the above and of course, it's a new unit.

 

[nickjb]

Yeah, the bodies are so cheap it's probably not worth fixing yours. Shame as it does seem wasteful but probably makes sense. I'd try the silicone spray first, but after that maybe go for the new body. This sort of thing (useful for all sorts of jobs, too) https://www.screwfix.com/p/flomasta-silicone-spray-200ml/6699x

Thanks again @nickjb. Can I squirt this through the voids next to the button? i.e. without opening the unit
Also, can I use 3-in-1 oil as I have that in the shed?

 

[nickjb]

Just squirt it in. It's much better than 3 in 1 for this. It'll penetrate better and with oil based lube you risk swelling anything plastic (only a tiny bit but that obviously won't help in this case) and it'll eventually pick up dirt and form a gummy mess. Silicone spray should just put a very light slippy surface on it. Its pretty readily available in Wilkos and often other Bargain World type shops, or screwfix as I linked to.

 

[Jupiter01]

Not expecting the worst...
But if this doesn't fix it, can a pay a bit more and get something better than what I had? I have a separate impact driver and use this for drilling (also have an SDS for heavy duty use) and gentler screwing. I must say it wasn't very good at masonry drilling. I would welcome any suggestions so I can start planning as I need an operational drill for the weekend.

This is my goto stuff for switches:

I've had some progress since starting this thread...
Makita have said they will repair this as part of my warranty. I didn't ask too many additional questions!

It's going back tomorrow for some TLC

In the meantime, I need to punch some holes in joists to pass cables (would have used the spade connectors on my combi drill). Can I use my Bosch SDS or impact Driver in some creative way to accomplish this please?

 

[lostinthelight]

These are handy for drilling joists if you dont want to pay for an angle drill

or one of these from TS fits impact driver but they wont stand a lot of abuse.

Balls ... disappointing, not gonna correct it now.

 

[Jupiter01]

I will look into the cost of hiring a combo drill for the weekend.

Have you tried simply cleaning trigger , sawdust and grease quickly clog it .
For tight spots I use 3D bits , cuts in every direction so you can curl it into joists as it cuts .
