On the models described, periodic lubrication of the chassis or steering components is not provided, with the exception of the rear wheel bearings.
Use oil or an aerosol can on hinges or joints with small gaps where grease cannot penetrate.
Friction surfaces are best lubricated with grease or treated with lubricating paste, as they adhere more firmly to the surface.
Before the onset of the cold season, spray a rust-corrosive and insulating spray into the keyhole. It lubricates, displaces water and protects the lock cylinder from rust and freezing in winter.
