How to repair the oil injection hole of the electric chain saw

If the electric chain saw does not spray oil, there may be air inside. The solution is:

1. Check whether there is air in the oil circuit. If there is air causing no fuel injection, remove the air from the oil circuit and the fault can be eliminated.

2. Check whether the oil supply of the oil pump is normal, and repair the oil pump if necessary.

3. Check the fuel system for oil leakage, and repair and tighten all connecting parts.

Extended information:

Although there are many different brands and models of electric chain saws, their structures are similar and all conform to ergonomic design principles.

Chain brake - also known as brake, is a device used to quickly stop the rotation of the chain. It is mostly used to brake chain saws in emergency situations and is one of the safety functions.

Saw chain gear - also called sprocket, is a toothed part used to drive the saw chain; its wear must be checked before use and replaced in time.

Front Handle - The handle mounted on the front of the chain saw, also known as the side handle. Front handle baffle - also called safety baffle, it is a structural barrier installed in front of the chain saw's front handle and guide plate. It is usually installed close to the front handle and is sometimes used as the operating lever of the chain brake. It is one of the safety functions.

Guide plate - also called chain plate, a solid track structure used to support and conduct the saw chain; the wear of the guide groove must be checked before use, repaired in time, and replaced if necessary.

Oil pump - a manual or automatic oil pump, a device used to refuel the guide plate and saw chain; check its oil supply before use, and adjust the oil supply in time. If it is seriously damaged, please replace it in time.

Rear handle - The handle mounted on the rear of the chain saw and is part of the main handle.

Saw chain - a chain with teeth for cutting wood, installed on the guide plate; check its wear and tear before use, file it in time, check its tension, and adjust it in time.

Timber tine - a tine that serves as a fulcrum for the chain saw when felling or cross-cutting, and to maintain position during cutting. Switch - A device that connects or disconnects the circuit to a chain saw motor during operation.

Self-locking button - also known as safety button, used to prevent accidental switch operation; it is one of the safety functions of the chain saw. Bar Head Guard - An accessory that can be attached to the bar tip to prevent the saw chain at the bar tip from contacting the wood; one of the terminology safety features

The electric chain saw is not spraying oil, maybe there is still air in it.

Solution:

1. Check whether there is air in the oil circuit. If there is air causing no fuel injection, remove the air from the oil circuit and the fault can be eliminated.

2. Check whether the oil supply of the oil pump is normal, and repair the oil pump if necessary.

3. Check the fuel system for oil leakage, and repair and tighten all connecting parts.

Precautions before operation

1. Safety shoes must be worn when working.

2. It is not allowed to wear loose and open clothes and shorts when working, and it is not allowed to wear accessories such as ties, bracelets, anklets, etc.

3. Carefully check the wear degree of the saw chain, guide plate, sprocket and other components and the tension of the saw chain, and make necessary adjustments and replacements.

4. Check whether the electric chain saw switch is intact, whether the power connector is securely connected, and whether the cable insulation layer is worn.

5. Thoroughly inspect the work site and remove stones, metal objects, branches and other discarded objects.

6. Select safe evacuation passages and safety zones before operating.
