[Sticking plunge mechanism on cordless plunge track saw]

It is the  Makita.

 

It also has a button that releases the plunge. It does this smoothly.

The problem is the return, the saw swinging back up to start so to speak.

I have to 'help' it pull it back up. 

I removed the blade and lubed the only points I can see that make contact that might prevent the saw from returning up to the start position but to no avail.

This is a new development. It has been an excellent saw for almost 2 years.

 

[Sticking plunge mechanism on cordless plunge track saw]

My cordless track saw is 1 1/2 years old and has preformed flawlessly...until this week.

Plunging is getting more difficult and it will not return by itself.

 

I removed the blade to see what I could see...nothing obvious.

 

Any ideas?

Thanks
