Manufacturer 52CC 2.0KW Gasoline Chain Saw

When the chainsaw engine is working, each moving part acts on another part with a certain force, and high-speed relative motion occurs. With relative motion, friction will inevitably occur on the surface of the part, accelerating wear. Therefore, in order to reduce wear, reduce friction resistance, and extend service life, lubrication systems must be installed on all engines.

The oil pump assembly of the chainsaw is a large part of the two-stroke chainsaw lubrication system. It provides oil to the high-speed running chain and guide plate to prevent excessive heat generated by friction during operation, which can cause the temperature of the chain guide plate to be too high and reduce work efficiency. It includes oil pump, oil pipe, oil filter, one-way valve, etc.

The fuel supply system of the chainsaw includes a fuel tank, filter, oil pipe, carburetor, etc. The carburetor is the core component of a two-stroke internal combustion engine. It utilizes the pressure difference generated by the crankcase to pump fuel from the fuel tank into the carburetor and spray it out through the fuel gauge hole. By utilizing the Venturi effect, the fuel is fully atomized, adjusting the ratio of fuel to air, and improving combustion efficiency.

1、 How to choose fuel for chainsaws and chain oil for chainsaws?

Usually, 90 # or above unleaded gasoline is mixed with specialized two-stroke engine oil.

The oil for chainsaw chains is basically SAE 10W-30. If divided by season, SAE 10W-40 is used in summer and SAE 10W-20 is used in winter. I recommend using specialized engine oil, which can better protect the smooth operation of the chainsaw, extend the service life of the machine, and reduce the probability of cylinder pulling.

A gasoline engine with a mixing ratio of 25:1 must use a two-stroke specialized engine oil.

2、 How does a chainsaw save fuel?

1. Lightweight chainsaws (displacement below 78) and specific gravity chainsaws (displacement above 78) are fuel-efficient.

2. How to save fuel with a new chainsaw. Choose a good carburetor. Under the same conditions, if the chainsaw consumes more fuel, adjust or change the carburetor.

3. How to save fuel with an old chainsaw. Usually, this type will have a gasoline filter and an air filter.
