Husqvarna H440e II Clutch & Oil Pump Chainsaw F.A.Q.

How do I properly adjust the chain tension on my Husqvarna H440e II Chainsaw?

To adjust the chain tension, ensure the chainsaw is turned off and cooled down. Loosen the bar nuts slightly, then adjust the tensioning screw until the chain hangs just a little below the bar. Tighten the bar nuts securely and ensure the chain moves freely.

What should I do if my chainsaw chain is not rotating?

If the chain is not rotating, check for a properly tensioned chain, ensure the chain brake is disengaged, and inspect the clutch for wear or damage. Clean any debris from the clutch area and replace any worn parts.

How can I troubleshoot oil pump issues on the Husqvarna H440e II Chainsaw?

Inspect the oil pump for blockages or damage. Ensure the oil tank is filled and the oil filter is clean. If the chain is not getting enough oil, clean the oil channels and replace the oil pump if necessary.

What type of oil should I use for the chain and bar lubrication?

Use a high-quality bar and chain oil specifically designed for chainsaws. This oil provides proper lubrication and reduces friction, extending the life of the chain and bar.

How often should I clean the air filter on my chainsaw?

The air filter should be checked and cleaned after every 5 hours of operation or more frequently in dusty conditions. Use warm soapy water to clean and ensure it is completely dry before reinstallation.

What is the correct fuel mixture for the Husqvarna H440e II Chainsaw?

The correct fuel mixture is 50:1, which means 50 parts gasoline to one part 2-stroke engine oil. Always use fresh, unleaded gasoline with a minimum 89 octane rating, and mix with high-quality 2-stroke oil.

How do I replace the clutch on my Husqvarna H440e II Chainsaw?

To replace the clutch, remove the bar and chain, unscrew the clutch cover, and use a clutch removal tool to unscrew the clutch. Replace with a new clutch, and reassemble the chainsaw parts in reverse order.

Why does my chainsaw stall during operation?

Stalling can be caused by a clogged air filter, dirty spark plug, or incorrect carburetor settings. Clean or replace the air filter, ensure the spark plug is clean and properly gapped, and adjust the carburetor settings according to the manual.

How do I perform regular maintenance on my chainsaw to ensure longevity?

Regular maintenance includes cleaning the air filter, inspecting and sharpening the chain, checking the chain tension, cleaning the oil pump and channels, and inspecting the spark plug. Follow the user manual for a detailed maintenance schedule.
