My 14.4v Making Combi died yesterday. Sob!

We have been together over for 4 years, every day, drilling thousands of
holes.

I wish now I hadn't dropped him from a ladder last year, or left him in
the rain before that. He didn't deserve that.

Sadly missed, he went as he would have wanted to, drilling a hole.

I wondered if it might be the brushes? If you pull the trigger nothing
happens, but if you twist the chuck it starts?

Can I resurrect Mr Makita?

You could try spraying some contact cleaner in through the motor
cooling slots and running it .. but be aware it might create a flame or
three to start with! Spray the trigger switch too if you can get close
enough to it.

We used to do this often with electric motors working in dusty or very
dry environments.

If you fancy opening it up, bearing in mind you've little to lose,
check the trigger and it's contacts. One I fixed recently had a
plastic part of the trigger broken, not allowing the trigger to press
the metal strip switch together. Quick repair with epoxy and job's a
good 'un ..

But NOT WD-40... :-)

This may be a silly question but why not? WD40 is the first thing I'd reach
for.

At that age and level of use that would be the most probable cause of
the type of failure you have observed.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember The Medway Handyman
saying something like:

Brushes are cheap enough to find out if that's the cause.
Just take out the old ones for a look, you'll soon see if they're short.

'cos WD40 is a basically a water dispersant. Although it's also a
cleaner, it's more likely to create a paste of elecrical/carbon
deposits and feck the motor good and proper rather than dispersing
them. Contact Cleaner cleans off carbon deposits from the brushes/comm
quite easily, but is a solvent with a low flash-point so might
'flame-out' a little ..

Well, it *could* be worn brushes - or a dirty commutator. But it's more
likely to be a duff winding. If it stops with a brush facing that
winding, it won't re-start. Move it round to a different position, and
it's ok. That sounds like your symptoms to me.

years ago I ressurected a dying/dead BnD strimmer using the old 12v
toy train "service" trick of raking out the ****e (carbon poss
softened by WD40...) from between the segments of it's commutator with
a pin. Did an entire overgrown garden with it after ;))

Well I live and learn, thanks for the tip.
