Small excavators are commonly used construction machinery, which can work in a narrow space. However, due to the short service life of small excavators and their vulnerability to damage, regular maintenance is required.

Generally speaking, the maintenance of small excavators includes daily maintenance, regular maintenance and special maintenance. Routine maintenance is essential, including regular inspection of machine parts, start-up test before use and shutdown test after use. Regular maintenance is generally carried out once a year or half a year, and the main purpose is to carry out a detailed overhaul of the whole machine. The special maintenance is to carry out some specific maintenance work under specific use conditions (such as long time work, large amount of use, and abnormal conditions).

Small excavators are very practical, but there are also some failures. Small excavators are common construction equipment and are also vulnerable to damage. Let's look at the common faults of small excavators.

The peculiar smell inside the cab is caused by the filter element of the small excavator that cannot be replaced in time or the filter element has been blocked. In addition, because the seal of the small excavator is not tight, it will also lead to peculiar smell inside the cab.

Engine oil burning is caused by the leakage of engine cooling water or the tightness of engine air brake. If the air brake of the engine is not tight, the engine cooling water will leak, which will cause the engine to burn oil.

The insufficient air intake of small excavators will also cause engine oil burning. There are many reasons for this situation, including engine air brake leakage, brake pad looseness, inductance switch failure, flywheel brake, flywheel failure, flywheel start, flywheel brake pad looseness and other reasons. If you want to repair this problem, you must repair it according to the specific situation.

There are many reasons for this situation, such as cracking of the wrap disc, loose flying disc, loose large disc, loose large disc brake pad, loose transmission belt and other reasons. To fix this problem, we must repair it according to the specific situation.
