Maintenance tips for small excavator parts

[DIG-DOG]

Engine maintenance:

Replace the engine oil and oil filter regularly to ensure that the engine is fully lubricated and reduce wear.

Check the air filter, clean or replace it in time to ensure smooth air intake, reduce engine wear and power loss.

Check the fuel filter to prevent fuel system blockage and ensure engine fuel supply.

Replace the spark plug according to the manufacturer's recommended schedule (for gasoline models) to keep the ignition system working properly.

Hydraulic system maintenance:

Replace the hydraulic oil and filter element, generally according to the manufacturer's recommended cycle, or replace it when the hydraulic oil becomes dirty or aged.

Check the hydraulic hoses, joints and cylinders to ensure no leakage, and repair or replace worn parts in time.

Clean or replace the return filter element and the oil suction filter element to ensure the cleanliness of the hydraulic oil.

Travel system maintenance:

Check the track tension regularly and adjust it in time to prevent the track from being too loose or too tight, causing early wear or breakage.

Clean foreign matter such as mud, gravel and other foreign objects on the track, and keep the guide wheel, sprocket wheel and other parts clean.

Check the track roller bearings, chain links, etc., and apply grease to prevent rust and excessive wear.

Maintenance of structural parts and accessories:

Lubricate the working devices such as booms, dipper rods, buckets, etc. regularly, especially the grease nipples of each hinged part, and apply grease on time.

After work, clean the dirt and oil on the surface of the excavation device to prevent rust.

Tire-type small excavators should check the tire pressure regularly, maintain the appropriate pressure, and reduce the risk of tire blowout.

Electrical system maintenance:

Check whether the cable line is damaged, whether the joints are tight, and ensure that the electrical components are waterproof and moisture-proof.

Clean the outside of the battery, check the electrolyte level, and keep the battery in good charge.

Cooling system maintenance:

Clean or replace the coolant in the radiator to ensure that the cooling system is unobstructed.

Remove dust and debris from the surface of the radiator to ensure good heat dissipation.

Storage maintenance:

When not in use for a long time, store the equipment in a dry, ventilated place that is not affected by corrosive substances.

Drain or replace hydraulic oil, fuel, engine oil and other liquids to prevent long-term storage and deterioration.

In general, the maintenance of small excavator parts is a systematic project. Each link requires careful inspection and maintenance according to the maintenance plan specified in the equipment manual, and appropriate adjustments are made based on actual usage.
