If your Philips hair clipper gives you an uneven cut, we advise you to check the following
Keep the flat part of the comb (the contact area) in full contact with your skin at all times.
If the clipper is pressed down to hard on your skin when it moves through the hair, the resulting length may not correspond with the desired hair length. Similarly, If the comb does not touch your skin when it moves through the hair, you will not get a an optimal cut.
The clipper is used in the direction of hair growth
You should always move the trimmer against the direction of hair growth. But since your hair does not all grow in the same direction, you need to move the clipper in different directions (upwards, downward and across)
The attachment comb is not adjusted correctly
Make sure the comb is adjusted correctly.
If you press the clipper against the skin too hard, you may accidentally change the setting.
To make sure you have correctly assembled the attachment, detach and re-attach it.
The hair clipper is not completely clean
Make sure the hair clipper has been cleaned in accordance with the user manual, as accumulated hair or dirt may reduce the performance of your clipper.
The battery is almost empty
Make sure the battery contains sufficient energy or that the adapter is connected to the mains properly
