Carbon Brushes are blamed for nearly all electric motor failures but other causes should be considered.
· Did the machine just stop.?
· Always check the power supply first. Unplug the tool and plug something else into the socket and see if it works.
· If that appliance works then you may as well check the fuse in the power tools plug ( The fuse is rarely the problem) If you have a tester then check the fuse if not swop the fuse with a fuse of a similar power from another working appliance. IMPORTANT If the power tool briefly starts and then stops and the fuse has blown again then you probably have a serious fault such total motor failure, cable short or other major electrical failure. These types of electrical failure can be DANGEROUS. DO NOT REPLACE THE FUSE AGAIN.
· Please give us a phone or find a local Power Tool repair agent to check the power tool over. If you don’t know one we can arrange to collect the power tool from you.
· If replacing the fuse made no difference then unplug the tool and if the motor has easy access to the brushes then take a look. You are looking for two brush caps and if you are lucky they will be visable on the outside of the tool. Normally they are black with a slot in them If you find one then the other one will always be opposite . Be gentle with the brush caps they can be brittle. Find the largest screwdriver that will fit the slot and before undoing give a slight twist clockwise ( and I mean slight) Now undo anti clockwise.
· Look at the carbon brush for a small round pin sticking out from the front of the brush face ( the bit touching the armature) if you find one then you probably only need brushes.
· Not all carbon brushes have a cut out built in but by looking at the carbon brushes we can tell a lot. If one brush is more worn than the other and maybe almost worn out is a good sign. You probably only need brushes. If both brushes are still long enough to touch the armature then it is probably not the Carbon Brushes. |
