Chain Tensioning
Proper chain tension is crucial for safe and efficient operation. With the bar attached, adjust the tensioning screw until the drive links sit snugly within the bar groove. A correctly tensioned chain should be pulled along the bar by hand, but not easily lifted from the groove. Regularly check tension, especially during initial use, as new chains stretch. Avoid over-tensioning, which can damage the bar and sprocket.
Starting the Chainsaw
Before starting, ensure the chainsaw is on a firm, level surface and the chain brake is engaged. Familiarize yourself with the start/stop switch location. For a cold start, prime the fuel bulb several times and set the choke. For a warm start, the choke may not be necessary. Pull the starter cord firmly and smoothly until the engine fires. Disengage the chain brake cautiously after starting.
Cold Start Procedure
When starting a cold engine, press the primer bulb repeatedly until fuel is visible. Engage the choke by moving the control to the ‘start’ position. Firmly grasp the chainsaw and pull the starter cord with a smooth, deliberate motion. Repeat several times until the engine attempts to start. Once running, gradually disengage the choke for optimal performance.
Warm Start Procedure
For a warm engine, avoid using the choke unless absolutely necessary. Position the start/stop switch to the ‘start’ position and firmly grip the chainsaw. Pull the starter cord with a smooth, consistent motion. If the engine doesn’t immediately ignite, a single, brief choke application may assist. Always ensure a secure footing and clear surroundings before attempting a restart.
Operating Instructions
Always inspect the chainsaw before each use, verifying chain tension and sharpness. Employ proper cutting techniques, maintaining a firm grip with both hands. Be acutely aware of potential kickback zones and avoid nose contact with wood. Ensure a stable stance and clear work area. Regularly check fuel and oil levels for consistent performance.

Proper Cutting Techniques
Maintain a firm grip with both hands, keeping your body to the side of the cutting plane. Utilize the lower portion of the bar for bucking, avoiding pinching. For felling, create a notch and back cut, ensuring a controlled fall direction. Plan each cut carefully, considering wood grain and potential hazards. Never overreach or cut above shoulder height, prioritizing stability and control throughout the process.
Avoiding Kickback
Kickback occurs when the guide bar’s tip contacts an object, causing a sudden, uncontrolled reaction. To minimize risk, avoid using the upper quadrant of the bar’s tip. Maintain a firm grip and proper stance. Keep the chain sharp and properly tensioned. Be aware of hidden obstacles and avoid plunging cuts. Always maintain control and anticipate potential hazards to prevent dangerous kickback situations during operation.
Maintenance Schedule
Regular maintenance is crucial for optimal performance. Husqvarna recommends frequent checks of chain tension and sharpness. Clean the air filter and spark plug regularly.
