When the lawn mower is stored for more than 30 days in winter:
First, drain the fuel in the fuel tank and start the gasoline engine until it stops due to fuel exhaustion.
Secondly, just in the warm state of the engine just shut down, first drain the oil in the crankcase, and then add new oil to the appropriate scale according to the recommended level.
Third, remove the spark plug, drip 5-10 ml of oil into the cylinder, rotate the crankshaft a few times, and install the spark plug.
Fourth, clean the dust and debris around the cutter head, machine body, cylinder block, cylinder head radiator, air duct, mesh cover and muffler.
Fifth, it should be placed horizontally on the ground during storage, and cover the lawnmower with a cloth to prevent dust from falling into it.
Sixth, clean the lawn mower thoroughly. Before the lawn mower is left unused for a long time in winter, the bottom of the lawn mower, the deck and the fuel tank cover should be thoroughly cleaned to prevent the residual weeds and mud from eroding the agricultural machinery. Before cleaning, remove the spark plug and the opening device, and use hoses, putty knives, and car cleaners to remove accumulated impurities from the landing gear and deck. Use a brush to remove the deposits on the vent of the mailbox to avoid blocking the vent.
Seventh, remove oil stains. If oil stains are in contact with the equipment for a long time, a chemical reaction will occur, causing the paint on the surface of the equipment to peel off, so it must be removed in time. When removing oil stains, first spray the degreaser on the oil stained area of the equipment, let it stand for 10-15 minutes, then wipe it clean with a towel, and finally rinse it with water.
Eighth, prevent rust on the exposed part of the lawn mower. Lubricant can be used to spray the exposed parts of the lawn mower, which can effectively prevent rust. Store the lawn mower in a dry place.
Ninth, check the vulnerable parts regularly. Develop the habit of regularly checking vulnerable parts and replace damaged parts in time. This will not only improve the working performance of the lawn mower, but also eliminate potential safety hazards.
