COMMON PROBLEMS

Common Failures and razor

Malfunction

Cause of issue

Approach

REMARKS

No work

Rechargeable shaver is not charged

Of charging time to see the back cover or manual razor

Dry electric shaver battery power is low

Replace batteries

Between moving and stationary utility knife (beard) too

Debris cleaned up after moving between fixed knife plus sewing machine oil

Lubrication See Note 1

Rechargeable battery overcharge or over-discharge or natural attenuation

Replacement battery

Battery Authentication see Note 2

Shaver long-term placement

Batteries: Remove the shaver to prevent battery leakage and damage the shaver
         rechargeable battery: long ago without adequate electricity and stored in a dry place

Rechargeable Shaver long-term need, we must put the charge cycle once every three months (full discharge, fully charge each time), otherwise, it will shorten the life of razors.

Motor damage

Replace the motor

Identification See Note 3

Switch is defective (oxide, metal deformation) or damage

Removing the oxide layer with sandpaper or replace the switch

Not clean shaven or clipped beard

Shaver soon no electricity, weak rotation

Charging

Between moving and stationary utility knife (beard) too

Debris cleaned up after moving and stationary knife
Room with sewing machine oil

Fixed blade deformation or damage

Between moving and stationary knife plus sewing machine oil or replace the fixed knife

Double or triple head rotary shaver, fixed blade must be replaced at the same time

Knife, fixed blade benefits is not enough

Replace the knife, the fixed knife

Head, the gap is too large nets

Adjustment screwdriver head, reducing the gap

Applicable only single-head rotary shaver

Head spring is too short or lack of resilience

Replace the blade spring

Applicable only reciprocating shaver

Motor rotation weakness

Replace the motor

Shaver working time is too short

Low battery

Of charging time to see the back cover or manual razor

Reduce battery capacity

Repeatedly charging and discharging the battery or replace the battery to activate

Fixed blade rotation

Nets bracket assembly deformation

Replace the grille bracket assembly

Applicable only double or triple head rotary shaver

Knife, fixed blade deformation

Replace the knife, the fixed knife

Between moving and stationary utility knife (beard) too

Debris cleaned up after moving and stationary knife
Room with sewing machine oil

Charging indicator light does not shine

Transformer Fault battery or circuit board

Replace the battery or transformer

Multimeter Test
         battery authentication see Note 2

When the charging time is significantly longer than the standard traffic light conversion charge time or traffic lights do not convert

Charging current or charging low conversion loss of control

Replace the circuit board

Shaver slow charge (charging time 8-12 hours): Standard Charging time 1 hour<Charging time <standard charge time +3 hours is normal.
         fast charge the shaver (charging time 1 hour): Standard charge time to 30 minutes<Charging time <standard charge time +30 minutes, it is a normal phenomenon.

Note:
1. sewing machine oil addition: Add at the razor rotation, add 2-3 drops / head.
2. Battery bad appraisal: DC voltage profile with a multimeter test. Rated voltage of 1.2V rechargeable batteries, test voltage: 0.9V, batteries are often normal; test voltage<0.9V, replace the battery. Rated voltage of 2.4V rechargeable battery, test voltage: 1.8V, batteries are often normal; test voltage <1.8V, replace the battery.
3. Motor bad appraisal: With power supply testing. Two motor terminals connected to the motor rated voltage, does not turn or rotate weakness, replace the motor. (Motor rotation weakness identified: hand Qingnie motor shaft is stopped, indicating motor rotation weakness.
