Makita grinder keeps tripping circut breaker


FIRST OF ALL !!
Control where the tool is used first for undervoltage on the mains supply group.

If it is everywhere a problem FIRST replace the circuit breaker.

After that control all connectors last check interference suppression capacitor.
If all are controled , relace armature or electric field or both.

I have a makita electric chainsaw rated at 1800w , do i need a special extension lead ?


I would say not
a normal 10 amp lead should be good enough
what you need is an extension box that has an inbuilt ELB in case you cut the lead or from a power point that has a ELB in the circuit breaker

Keeps blowing internal breaker


The unit rated at 3 HP at 115 volts draws 13.8 amps is odd, a HP in watts is 745 and should be about 2200 watts and 19 amps plus a efficiency loss. Odd to see the ratings don't jive with electric theory/formulas.
The compressor should be connected directly to the wall and if using an extension cord, the cord needs to be #12 AWG or larger to avoid line voltage loss and over amping of the motor.
Here is contact and support info: For more information, please call 800/4-MAKITA (800/462-5482) or visit makitatools.com.
My bottom line is, A 115V motor circuit needs 10 amperes per horse power or 30 amp circuit for 3 horse power. Using extension cords calls for upgrade in wire gage of the cord. The advantage of using 230 volts is it cuts the amperes in half and allows use of smaller gage wire. Watts, or volt amperes is the product of volts and amps.

I have a makita hm 1810 hammer green light stays on hit switch light goes off


As stated in the manual:
The green power-ON indicator lamp lights up when the tool is plugged to the mains. If the indicator lamp is lit but the tool does not start even if the tool is switched ON, the carbon brushes may be worn out, or the motor or the switch may be defective. If the indicator lamp does not light up, the mains cord or the indicator lamp may be defective.

Turns on for about 20 seconds, turns off and pops breaker. I've replaced the switch and the brushes. What else could it be?


what did the brushes look like before replaced, if they were burnt or pitted then you have a major electrical issue probably. UNPLUG tool and remove the replaced brushes and check them for their condition. Does the blade spin freely? If not you could have a bearing issue or an obstruction. Also how is the power cord, is the insulation broken which can cause an electrical short. These are all possible items that can cause your problem. If this unit has a resetable breaker it could also be the issue. Hope this gives you some idea of where to continue to look

Makita "7 1/4 inch" circular saw poblem. the saw seems to lose power soon into ripping boards. if you letit sit andcool, it will work again, but will quickly cease upagain. the saw blade seems to go...


Clean the armature and install new brushes, the armature is burned with carbon and loses its ability to conduct electricity properly. Make sure to in between every copper rib on the armature so it doesn't ground itself back out.

Loses power (Maketa Breaker)


If the air-hammer is working fine at first but then starts to fail as you use it.
I would look at the breaker unit, see if it is covered with frost. These units require a lot of air. A 1inch hose is usually used to connect it to the air supply. If you are not using an oiler, that could be the problem.
Check that the hose is in good shape and is free from damage or kinks.
Check the air gauge and see what the compressor is creating for air.
The compressor should be building and maintaining 125 to 175 psi.
I am guessing that you have this hammer hooked up to some type of worm drive system. Let me know if I can be anymore help.
