The blade of a pet hair shaver needs regular lubrication, which is a key step in maintaining equipment performance and extending its service life. The specific points are as follows:

1. The core function of lubrication
Reduce metal friction: When the blade moves at high speed, the friction between metals will generate high temperatures, exacerbating wear. Lubricating oil forms a protective film to prevent the blade from becoming dull or stuck.
Preventing rust and corrosion: Moisture and sebum in pet hair can accelerate the oxidation of the blade, while lubricants isolate moisture and air to protect metal parts.
Reduce work noise: The dry grinding blade will make sharp friction sounds, and after lubrication, it runs quieter, reducing pet tension.

2. Operation steps (taking common models as examples)
Step 1: After cleaning, lubricate and thoroughly dry the blade. Do not apply oil in a damp state (mixing water and oil can easily form sludge).
Step 2: Accurately Drip Professional sewing machine oil or pet shaver specific oil onto the joint of the blade edge (usually marked with a fine seam), 1-2 drops are enough, excessive amount will adhere to the hair.
Step 3: Run the oil evenly and install it back into the cutting head. Start the machine and run it idle for 10-15 seconds to allow the lubricating oil to penetrate into the internal bearings. Finally, use a cotton cloth to wipe off any excess oil stains on the surface.

3. Precautions
Reject substitutes:  Cannot use edible oil (easily clogged), WD-40 (containing solvent damaged coating), engine oil (too viscous).
Frequency control:
Lubrication is required every 2 hours of continuous use;
Lubrication and rust prevention are necessary before long-term storage.
Safety priority: After lubrication, be sure to wipe off any spilled oil to avoid residual oil coming into contact with pet skin or being licked.

**The consequences of not lubricating
The blade heats up too quickly, causing burns to the pet's skin;
Blade jamming and pulling hair, pets resist trimming;
The increase in motor load shortens the lifespan of the entire machine.
