First of all, the cutting edges and pores inside and outside the cutter head are easy to hide in shavings and dander, so after each use, they should be cleaned up with a small brush immediately. Because the solidification of shavings and skin oil will hinder the operation and sharpness of the blade, it is necessary to frequently clean up the debris remaining on the blade.
Secondly, because the outer knife is relatively thin, do not push it vigorously during use to avoid deforming it. Once deformed, it will hinder the rotation of the inner knife, and in severe cases, it may hurt the skin and even bleed. However, if the cutting edge is deformed or damaged, it should not be used again, otherwise there will be a danger of cuts.
Then, in order to maintain the performance of the battery, it should be used within an ambient temperature of 0-40°C. When not in use for a long time, the dry battery should be taken out and stored to avoid damage to internal parts due to liquid leakage.
In the back, the switch should be turned off after use, and in order to protect the blade, put on the protective cover, and then put it back in the box and install it.
