30W | 7FW | 5FW | 4FW High-Carbon Steel 62 Rockwell Hardness Scale Saves time for grooming Maintenance: Lubricate the blades with a blade oil, wipe off any excess oil before use, and operate the clipper for 5 seconds prior to grooming, as failure to follow these guidelines may impact cutting effectiveness. Please, do not use coolant sprays, rem oil, WD-40 as lubricants. Insufficient lubrication and care of blades leads to reduced cutting life span from months to mare weeks.
