Hi, I have a Whal arco, batteries are charged, changed blade but when motor comes against pressure it just stops. Any suggestions? Thanks Lauren

8 years is pretty good for a rechargeable battery, I would say yes the battery needs to be replaced, although it may be cheaper to purchase a new shaver ?

Hi there, I do not know the Craftsman mowers, but have experienced same problem with other makes. Suggest that you try the following, in this order. 1. Check that battery has water above top of plates. 2. Check that battery is well charged. Turn headlights on full and crank motor. If lights go VERY low then battery either needs charged from external mains charger or is defunct. Place large mirror in front to view lights during test. 3. Test that engine charging system is recharging battery during use. If battery is very low some systems will still start motor, but charger will not work. [Normally when this happens the dash charging light will show. Orange.]
The problem can be that as the electric clutch requires a lot of power to initiate the drive and a considerable load while running, if the battery is too low the engine generator cannot carry the load and so the system drops out. This may also stop the engine.

change the bit (rotery blade)
if it stops so the engine is burnd out (magnetic filds)

GE suggests to purchase a new washer and fan blade when changing the evaporator fan motor.

The two screws under the blade hold the blades on. Removal is not the problem, refitting and aligning is. The stationary blade must jut out about 0.010" more than the moving blade or that blade will cut into the skin being shorn. Sharpening the blade is also a job requiring professional attention.

Hi

There can be a number of reasons why it stopped working. When you have already changed the battery, then it must be something wrong with the inner mechanism. Try cleaning the circuit board.Take the razor apart (you need very small Phillips screwdrivers). Clean the circuit board with small amount of alcohol and q-tips, being careful not to catch any cotton on the components of the board. At this point you can at least confirm that the motor is not burnt out and the batteries are charged by placing a flathead screwdriver between the positive terminal of the battery and the motor. It should come on if the motor and batteries are okay. Press reset button at then see if it comes on using the on/off button. You can do this step with the razor disassembled or assembled.

Please get back to us if you have further query else please accept the suggestion.

Here some toubleshooting:

Problem 1. Fan will not start.
Probable Cause
1. Fuse or circuit breaker blown.
2. Loose power line connections to the fan, or loose wire connections in the switch housing.
3. Reversing switch in neutral position.

Suggested Remedy
1. Check main and branch circuit fuses or circuit breakers.
2. Check line wire connections to fan and switch wire connections in the switch housing.
3. Make sure reversing switch position is all the way to one side.

WARNING: Make sure main power is turned off.

Problem 2. Fan sounds noisy.
Probable Cause
1. Blades not attached to fan.
2. Loose screws in motor housing.
3. Screws securing fan blade flanges to motor hub are loose.
4. Switch housing binding against the blade hub.
5. Wire connectors inside switch housing rattling.
6. Screws holding blades to flanges are loose.

Suggested Remedy
1. Attach blades to fan before operating.
2. Check to make sure all screws in motor housing are snug (not over-tight).
3. Check to make sure the screws which attach the fan flanges to the motor hub are tight.
4. Check to make sure that the switch housing does not bind against the blade hub.
5. Check to make sure wire connectors in switch housing are not rattling against each other or against the interior wall of the witch housing.
6. Tighten screws securely.

WARNING: Make sure main power is turned off.

Problem 3. Fan wobbles
Probable Cause
1. Setscrew in motor coupling is loose.
2. Setscrew in the hanger ball/downrod assembly is loose.
3. Screws securing fan blade flanges to motor hub are loose.
4. Fan blade flanges not seated properly.
5. Hanger bracket and/or outlet box is not securely fastened.
6. Fan blades could be out of balance.

Suggested Remedy
1. Tighten the setscrew in the motor coupling.
2. Tighten the setscrew in the hanger ball/downrod assembly.
3. Check to be sure screws which attach the fan blade to motor hub are tight.
4. Check to be sure the fan blade flanges seat firmly and uniformly to the surface of the motor hub. If flanges are seated incorrectly, loosen the flange screws and retighten.
5. Tighten the hanger bracket screws to the outlet box, and/or secure outlet box.
6. Interchanging an adjacent (side-by-side) blade pair can redistribute the weight and result in smoother operation.

WARNING: FOR YOUR OWN SAFETY TURN OFF POWER AT FUSE BOX OR CIRCUIT BREAKER BEFORE TROUBLESHOOTING YOUR FAN!!!

Hope helps.

if the problem arrears to be with one blade on several clippers it sounds like you need to send the clipper blades for sharpening.

In my case noise was coming from the plastic blade rubbing against the sheet metal housing. I removed the motor and added 2 washers to the mounting screws. The washers acted as spacers and lifted up the motor/blade assembly with respect to the sheet metal housing. The blade no longer rubbed against the housing and the noise stopped.
