How often should I oil the Braun Type 5544 hair clipper to keep it working properly?
Oil the trimmer regularly with light machine oil (not included) to maintain optimal performance. Keep in mind that exposure to temperatures higher than 122°F/50°C for extended periods of time could damage the appliance.
