I. Storage of the engine

1. Release the cooling water in the engine of the small excavator.

2. Replace the engine oil of small excavator. The new oil is usually neutral and will not corrode the metal parts of the engine.

3. Fill the fuel tank with diesel to avoid rust in the fuel tank. If conditions permit, preservatives should also be added.

4. During the shutdown period, the engine should be started once a month, so that the machinery can travel a short distance, so that each part of the lubrication to establish a new oil film to prevent rust. It should be noted that the cooling water should be filled before the start, and the cooling water should be discharged at the end.

Two, storage battery

1, should remove the battery, put the battery in a dry and antifreeze place, need to keep its surface clean and dry, strictly prohibited in the battery above placed conductive objects, remove the battery, first should cut off the negative line, and then cut off the positive line, when the installation should first connect the positive line and then connect the negative line, Because the electrical system of construction machinery is negative, this is in order to prevent the battery disassembly caused by short circuit.

2. The lead-acid battery should be charged once a month.

Three, rust prevention treatment

1, before storage should be based on the size of the outer surface anticorrosive paint patent-off area to determine whether to use the method of painting or the method of repainting the whole machine to repair.

2. The working devices of engineering machinery, such as the ironing plate of pavers, the bucket of loaders and the scraper of graders, etc., the rust prevention method of the exposed place of metal is to smear butter.
