2. Safety Instructions

Always prioritize safety when operating power tools. Read and understand all safety warnings and instructions before using the chainsaw. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.

2.1 General Safety

• Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2.2 Personal Safety

• Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, gloves, and sturdy footwear.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
• Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication.
• Avoid accidental starting. Ensure the switch is in the off-position before connecting to battery pack, picking up or carrying the tool.

2.3 Chainsaw Specific Safety

• Always hold the chainsaw firmly with both hands during operation.
• Ensure the chain is properly tensioned and lubricated before each use.
• Be aware of kickback. Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.
• Do not overreach. Keep proper footing and balance at all times.
• Never operate the chainsaw above shoulder height.
• Inspect the area for obstacles such as wires, fences, or other debris before cutting.
• Remove the battery pack when not in use, before cleaning, or when changing accessories.

5.2 Installing the Chain and Guide Bar

Refer to the diagram on the product for visual guidance. Always wear protective gloves during installation.

1. Remove the battery from the chainsaw before installation.
2. Unscrew the threaded nut cover on the side of the chainsaw using the provided wrench.

• Chain Tension: Check chain tension before each use. Adjust as needed to prevent the chain from derailing or binding.
• Chain Lubrication: Ensure the chain is adequately lubricated. While this model may not have an automatic oiler, manual application of chain oil is recommended for prolonged chain life and smoother operation.
