2. Safety Information
Always prioritize safety when operating power tools. Failure to follow safety instructions can result in serious injury.
General Safety Rules
- Read the entire manual: Understand all instructions and warnings before operating the tool.
- Wear appropriate personal protective equipment (PPE): This includes safety glasses, gloves, hearing protection, and sturdy footwear.
- Keep work area clear: Ensure no bystanders, children, or pets are near the operating area.
- Maintain a firm grip: Always hold the pruning saw with both hands during operation.
- Avoid awkward positions: Ensure stable footing and balance. Do not overreach.
- Inspect the tool before each use: Check for damaged parts, loose components, or any other condition that may affect safe operation.
- Use the correct battery and charger: Only use batteries and chargers specified by Husqvarna or compatible with the Power For All Alliance 18V system.
- Do not operate in wet conditions: Avoid using the saw in rain or damp environments.
- Disconnect battery when not in use: Always remove the battery before making adjustments, changing accessories, or storing the tool.
Specific Chainsaw Safety
- Beware of kickback: Kickback can occur when the moving chain contacts an object at the upper tip of the guide bar or when the wood closes in and pinches the chain in the cut.
- Ensure chain lubrication: The chain must be manually lubricated regularly to prevent wear and ensure smooth operation.
- Never cut above shoulder height: This can lead to loss of control.
- Do not cut small, unsupported branches: These can get caught in the chain and be thrown towards the operator.

5.2. Pruning Techniques
- Assess the branch: Identify the cutting point, considering the branch's weight and direction of fall.

- Cutting small branches: For branches up to 75 mm, position the saw firmly against the branch before engaging the chain. Allow the saw to do the work; do not force it.
