Spring is coming, all things recovery, even beard grow faster than in the winter, even men shave with the rhythm of the more frequently than usual. Recently, the author found in circle of friends to have a friend, for my own use electric razors for eight years, now in use from time to time is strong weak, when from already check once, feel the circuit there is no problem, I don't know why.

So, if your family problems in the process of using electric razor, oneself how to judge, how to repair it? To this, this big bang columns is to talk about this topic, interested dear friends may wish to consider.

An electric razor:

Common faults and maintenance methods:

The first condition:

Rotating blades after turning on the power supply is not rotating or reciprocating motion. Appear such circumstance, may be caused by the following factors.

This could be the battery voltage is too low, can use a multimeter dc voltage profile measuring voltage; Also can use 1.5 V ~ 1.5 V flashlamp and, judging by depending on the brightness voltage levels. If the voltage on the low side, should replace the dry cell, if use rechargeable batteries, should charge in a timely manner.

It could also be razor we use ac power, plug, plug contact undesirable, or the power cord is broken. At this point, suggesting a plug, if there is a fault should be timely repair plug.

Power switch contact oxidation wear, poor contact, also may be the cause of rotating blades is not rotating or reciprocating motion. At this point, we can use anhydrous alcohol cleaning contact, a layer of solder alternative weldable.

Battery and battery poor contact, also can appear rotating blades rotating or reciprocating motion. Because of the battery spring from battery leakage corrosion, causing poor contact, use sandpaper to remove accumulated dirt. If caused by insufficient elasticity of spring, but in the battery at the bottom of the mat into the sheet metal, make good contact.

Net shape, stuck moving blade also can appear when rotating blades rotating or reciprocating motion. You can find a similar to net inside surface shape of non-metallic materials, such as cloth, line ball, sand, etc.), inner surface and extrusion on the net, to restore its original geometry. If the net is broken, and a new product should be replaced.

Also, when the motor carbon brush serious wear and tear or fall off, also can appear rotating blades rotating or reciprocating motion. It is recommended to replace, grinding, or heavy carbon brushes.

If the motor rotor broken wires, circuit caused by the rotating blades is not rotating or reciprocating motion, is recommended friend send razor to professional maintenance shop.

The second condition is seen:

Abnormal or slow moving blade rotation, shaving the effect not beautiful. The following reason can let the razor appear this kind of situation.

When the power supply voltage is too low, or inadequate to dry will run out or rechargeable batteries. If use the ac power, can be used again after the voltage is normal. Dry cell to use for a long time to change new battery, rechargeable battery should be charged.

Moving blade dull blade, dynamic blade should be sharpened or replaced.

A foreign body blade gets stuck, break down the blade and shaft parts, removal of foreign bodies.

Motor bearing oil shortage or serious wear and tear, and can be loaded with a little oil (white oil) or change the bearing the same specification.

Carbon brush serious wear and tear, commutator accumulate dirt poor contact, causing the deterioration of motor speed. Repair or replace carbon brush. Clean with anhydrous alcohol commutator.

Rotor winding short circuit, after check, professional repair shop repair.

The third common problem:

Big noise, accompanied by vibration.

Motor bearing oil shortage or serious wear and tear. Can be loaded with lubricating oil or replace bearing.

Motor shaft bending deformation, causing the rotor and the stator phase. The spindle should be plastic or replace the rotor.

Net and the blade clearance is too large, when rotating blade jumped up and down move. Adjustable moving blade wheel center adjustment screw, increasing the spring pressure, or further tighten the net.

A fourth condition:

Electric shavers charging indicator but won't charge electricity phenomenon.

This may be a rectifier diode is damaged, should replace the diode.

May also be a current limiting resistor open circuit, a current limiting resistor should be replaced.

Or a rechargeable battery failure, it is recommended that the change of rechargeable batteries.

Electric shavers: daily care and maintenance methods

How to maintain the battery

If it is a plug-in must knife, had better let it runs out of battery, recharge. Is finished with a charge once. Charge for the first time, in full recharge time - on the basis of charging more 3 to 4 hours. (1 hour full electric charge 4 hours, 8 hours of full electric charge 12 hours) if it is - the battery must be knife, pay attention to the replacement of the battery. Best can take out the battery, after each use to prevent battery leakage. Usually it is best to use alkaline batteries.

How to maintain must/dao bao

Is the main part of the cutting tools, the beard clean inside after each use. Use one to two months later, open the tool bit, share the blade knife nets, - and then use the brush to flush - contact beard and all parts of the cutting tools, and do not beard. The most common way of cleaning of the cutting tools is to use clean water to rinse. The body it is best not to encounter water flushing, razor, lest produce equipment failure. If you use the product - is a dry wet amphibious model, base part - but still not come into contact with water, so as not to damage the motor. This can prolong the service life of cutting head, and ensure the use effect.

The maintenance of the other components

Had better be careful not to let the head - any external extrusion - and stress, so as to avoid deformation of the cutting tools. At ordinary times need not when, to the cutting head protection cover to cover. Don't throw to knife, avoid the fuselage wire loose or short circuit.
