Switzer Petrol Chainsaw - 63Cc 2400W 20"

Always refer to the specific user manual for the recommended fuel-to-oil ratio for 2-stroke engines. Typically, it is a 25:1 or 50:1 ratio with high-quality 2-stroke engine oil.

Sharpen the chain when you notice a reduction in cutting performance, if it starts to 'dust' rather than 'shave' the wood, or if it produces a whining sound. Frequent sharpening during use is recommended for optimal performance.

While capable, this is a professional-grade, high-powered chainsaw. It is best suited for heavy-duty tasks like felling trees and processing large logs. For light pruning or small yard work, a smaller, less powerful saw might be more appropriate and safer.

Use a dedicated bar and chain oil. Do not use waste oil or motor oil, as these can clog the lubrication system and lead to premature wear.

Ensure the engine is cool before storing. Empty the fuel tank if storing for an extended period to prevent fuel degradation. Store in a dry, secure location away from children and flammable materials. Use a bar scabbard for protection.

Please consult the product documentation or the retailer for specific warranty information, as it can vary.

Check fuel-air mixture, ensure choke is correctly set, verify spark plug is clean and properly gapped, and check the air filter for obstructions.

Clean or replace the air filter, check fuel quality and mixture, ensure the spark plug is in good condition, and verify chain brake is disengaged.

Check the chain oil level, ensure the oiler adjustment is set correctly, and clean the oiler outlet hole and the bar's oil groove.

Re-tension the chain correctly, ensure the guide bar is not worn or damaged, and check that the chain is the correct type and size for the bar.

Clean the air filter, check fuel quality and mixture, ensure the chain is sharp and properly tensioned, and check for any engine or exhaust blockages.
