The Hair Clipper Freezes After Long-term Use. What Are The Possible Causes And How To Solve It?
Causes and solutions for the hair clipper to jam after long-term use
If the hair clipper jams after long-term use, it will seriously affect the efficiency and experience of haircutting. It is usually caused by the following reasons and has corresponding solutions:
I. Blade problem
(I) Accumulation of hair and dirt on the blade
After long-term use, hair debris, dandruff, and dust will accumulate in the gaps and between the teeth of the blade, hindering the normal engagement and operation of the blade, and thus causing jams.
Solution: Turn off the hair clipper and unplug the power supply (make sure it is turned off for rechargeable models), and use the cleaning brush provided with the hair clipper to carefully clean the hair and dirt on the surface of the blade, between the teeth and in the gaps; for stubborn dirt, use a cotton swab dipped in a small amount of alcohol to gently wipe it, and apply special lubricating oil on the surface of the blade after cleaning to ensure smooth operation of the blade.
(II) Blade wear
Frequent use or improper use will cause the sharpness of the blade to decrease and the blade to wear, making the blade not smooth enough when cutting hair and jamming. Especially for blades with relatively poor wear resistance such as carbon steel and stainless steel, the wear will be more obvious.
Solution: If the blade is lightly worn, you can use a special sharpening tool to grind and repair it; if it is severely worn, you should replace it with a new blade of the same model in time. When replacing, follow the instructions to ensure that it is installed in place to avoid new problems caused by improper installation.
II. Power system failure
(I) Motor overheating
When the hair clipper is used continuously for a long time, the motor will continue to run and generate a lot of heat. If the heat is not dissipated in time, it will cause the motor to overheat, performance will decline, and jamming will occur. In addition, the heat dissipation holes of the motor are blocked by hair and dust, which will also affect the heat dissipation effect.
Solution: Stop using the hair clipper and let the motor cool naturally for a while; check and clean the blockages at the heat dissipation holes of the motor to ensure that the heat dissipation holes are unobstructed; when using the hair clipper, follow the "intermittent use" principle to avoid long-term continuous operation and reduce the risk of motor overheating.
(II) Loose or worn transmission parts
The transmission gears, belts and other parts inside the hair clipper may become loose or worn after long-term use, resulting in poor power transmission and jamming.
Solution: Open the hair clipper shell (non-professionals should operate with caution or contact after-sales service) and check whether the transmission parts are loose. If they are loose, use appropriate tools to tighten the fixing screws; if the transmission parts are severely worn, replace them with new ones and add appropriate amount of lubricating oil after installation to ensure smooth transmission.
III. Improper use and maintenance
(I) Insufficient or deteriorated lubricating oil
The normal operation of the hair clipper's blade and transmission parts depends on lubricating oil. If lubricating oil is not added for a long time, or the lubricating oil deteriorates due to long-term use, the friction resistance between the parts will increase, causing jamming.
Solution: According to the requirements of the hair clipper manual, regularly add special lubricating oil to the blade and transmission parts; if the lubricating oil has deteriorated, clean the old lubricating oil first, and then add new lubricating oil to ensure the lubrication effect.
(II) Using an incompatible power supply
For rechargeable hair clippers, if an incompatible charger is used, or the voltage is unstable during charging, it will affect the battery performance and the normal operation of the motor, causing jamming; similar problems will occur if the power cord of a plug-in hair clipper is damaged, the contact is poor, or the voltage is inconsistent.
Solution: Rechargeable hair clippers must use original or matching chargers and charge in a stable voltage environment; if the battery aging causes performance degradation, replace it with a new battery in time; for plug-in hair clippers, check whether the power cord is damaged and whether the plug is in good contact. If necessary, replace the power cord or repair the power interface.
