Clean the chain and sprockets by removing all dirt, sand, dust and old lubricant and let the chain evaporate for 10 minutes if necessary to allow the volatile parts of the applied cleaner to evaporate. Shake the aerosol well before use. Spray the grease evenly on the inside of the chain, ± 10 cm in front of the rear sprocket. Turn the rear wheel to distribute the grease over the chain and massage it between the chain rollers and sprockets.
