Frequently Asked Questions - QW146374 HUSQVARNA
What type of fuel should I use?
Use a 50:1 petrol-to-oil ratio with a high-quality 2-stroke engine oil. Always mix fresh petrol and oil in a clean container, and never use old or stale fuel.
How do I start the chainsaw?
First, activate the chain brake and move the ignition switch to the ON position. Set the choke to the closed position, grip the front handle, and pull the starter handle until the engine fires. Then push the choke back and continue pulling until the engine runs smoothly.
What safety gear is required?
Always wear protective gloves, safety glasses or a face shield, ear protection, chainsaw boots with protective toe caps, and chainsaw protective trousers to reduce the risk of injury.
How do I adjust the chain tension?
Loosen the bar nuts slightly, then turn the tensioning screw to adjust. The chain should fit snugly against the bar with no droop. Lift the bar tip while tightening the nuts to maintain correct tension.
What oil should I use for the chain lubrication?
Use a high-quality biodegradable chain oil or standard SAE 30 oil. In cold climates, a thinner oil improves flow. Ensure the oil tank is refilled before each use to avoid chain damage.
How do I sharpen the chain?
Use a round file matching the chain pitch (3/8") at a 30° angle. File each tooth with a few even strokes, and periodically check the depth gauges. Always sharpen from the inside out.
What is the chain brake and how does it work?
The chain brake is a safety device that instantly stops the chain in case of kickback. It can be activated manually by pushing the front guard forward, or automatically by inertia sensors during a sudden movement.
How do I clean the air filter?
Remove the air filter cover, take out the filter, and clean it with a soft brush or low-pressure compressed air. Avoid using solvents. Reinstall the filter and make sure it sits correctly before starting the engine.
Where can I find spare parts?
Genuine Husqvarna replacement parts are available from authorized Husqvarna dealers and official online distributors. Always use authentic parts to maintain performance and safety.
How should I store the chainsaw?
Drain the fuel tank and run the engine dry, clean the saw thoroughly, and loosen the chain tension. Store in a dry, covered area away from moisture and directly from sunlight.
