STIGA Petrol Chainsaw - CS 540

Always use a high-quality 2-stroke engine oil mixed with unleaded gasoline at the ratio specified in the product manual. Typically, this is 50:1 for modern engines.

The tensioning wrench is located under the rear handle. Loosen the bar nuts slightly, then use the wrench to adjust the chain tension. The chain should be snug but still rotatable by hand. Retighten the bar nuts securely.

The air filter should be checked and cleaned regularly, especially in dusty conditions. The tool-less cover allows for quick access for cleaning.

This model comes with a 5-year manufacturer's warranty, subject to terms and conditions.

The CS 540 is designed primarily for domestic use, such as chopping wood and logs. While powerful, it may not be suited for the high demands of professional logging. Additionally, it is intended for trained tree service operators.

The chainsaw features an automatic and adjustable oil pump. Ensure the bar oil reservoir is filled with appropriate bar and chain oil. Check the oil flow by running the chain briefly against a light-colored surface; you should see a line of oil.

Ensure the fuel tank is filled with the correct fuel mixture. Check that the choke is set correctly for starting. Verify the spark plug is clean and properly gapped. Ensure the ignition switch is in the 'on' position.

The chain may be dull and require sharpening. Check that the chain tension is correct; it should not be too loose or too tight. Ensure the automatic oil pump is functioning and lubricating the bar and chain.

The air filter may be clogged and require cleaning or replacement. Check the fuel filter for blockages. Ensure the correct fuel-to-oil ratio is being used.

While the anti-vibration system is designed to reduce vibrations, check that all components are securely fastened. Ensure the chain is properly tensioned and sharpened. If vibrations persist beyond normal levels, contact customer support.
