Makita GA4030K: Which grease to use on Makita machines

Wed, 02 Sep 2015 21:18:04 -0700

All Makita technical manuals mention a "Makita grease SG No. 0" for lubrication but where to find it? What kind of grease is that? Is there a brand and type like Molycote, Castrol or other to replace it? What to use?

Makita GA4030K: Angle grinder is getting very hot when I use it.

Tue, 02 Feb 2021 03:22:13 -0700

I have had my angle grinder for quite some time and while using it today I noticed that the body of the tool was becoming quite hot. I turned it off and unplugged it as this has never happened before and I was quite concerned. Can someone please tell me what might have happened to cause this and how I can go about fixing it?

Makita GA4030K: Angle grinder won't turn on after I dropped it.

Sat, 13 Jun 2020 14:45:09 -0700

I was using my angle grinder to work on a small project the other evening when I was startled and dropped the grinder off of my work bench. Now, when I try to use it, the grinder won’t turn on at all. I tried plugging it into several different outlets throughout my house and that doesn't seem to be the problem so I think it must be the grinder itself. Is there any way to fix this?

Makita GA4030K: What is causing my angle grinder to make so much noise?

Tue, 26 May 2015 07:11:45 -0700

For the past several days I have been using my Makita GA4030 to work on an extensive project for many hours at a time. As I was using it this afternoon I noticed that the grinder started making a funny noise that it has never made before. What’s going on? Is this something worth fixing or should I just go buy a new one?

Tue, 25 Feb 2025 20:53:41 -0700

I cannot get the plastic rear cover off the main body.

I have removed the ON/OFF switch button so the switch lever can move freely.

Something else seems to prevent the cover from coming off.

Does anyone know how to get it off?
