Makita RIP
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? -- Dave - The Medway Handyman www.medwayhandyman.co.uk |

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 .. -- Paul - xxx |

WD40 is the first thing I'd reach for. '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 .. -- Paul - xxx |

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: 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? 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. |

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. -- Cheers, Roger ____________ Please reply to Newsgroup.

Whilst email address is valid, it is seldom checked. 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 ;)) Jim K |
