2. Safety Instructions
Always prioritize safety when operating power tools. Read and understand all instructions before use. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.
2.1 General Safety Warnings
- Work Area 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.
- Electrical Safety: Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Personal Safety: Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, hearing protection, and sturdy footwear. Dress properly; avoid loose clothing or jewelry that can get caught in moving parts.
- Chainsaw Specific Safety: Keep all parts of the body away from the saw chain when the chainsaw is operating. Ensure the chainsaw is switched off before connecting to the battery, picking up, or carrying the tool.
- Maintenance: Maintain tools with care. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation.

4. Setup and Assembly
Follow these steps to properly assemble your Gisam DJ-8 Mini Chainsaw.
4.1 Chain and Guide Plate Installation
- Remove Cover Plate: Turn the cover plate counterclockwise to remove it from the chainsaw body.
- Install Chain and Guide Plate: Carefully place the saw chain around the guide plate. Ensure the small blade (cutting edge) is always positioned at the front, in the direction of the chain's rotation. Then, align the guide plate and chain with the chainsaw's drive sprocket.
- Tighten Chain: Locate the small silver knob. Turn this knob downward to tighten the chain. The chain should have a slight elasticity of 1-3mm when pulled from the guide bar. Do not overtighten.
- Secure Cover Plate: Reinstall the cover plate and turn it clockwise to secure it firmly in place.

4.2 Battery Installation
Insert a charged 4Ah battery into the battery slot on the chainsaw handle until it clicks into place. Ensure it is securely seated before operation.
5. Operating Instructions
Before operating, ensure you have read and understood all safety warnings and assembly instructions.
5.1 Lubrication
The chainsaw features an automatic lubricator. Before each use, or as needed during extended operation, pour appropriate lubricating oil (not included) into the oil reservoir. Then, press the oil pump button 1-2 times to ensure the chain is adequately lubricated. Proper lubrication extends chain life and improves cutting performance.
5.2 Starting the Chainsaw
To start the chainsaw, install a charged battery. Simultaneously press the safety button (usually located on the side of the handle) and the main trigger switch. Release the safety button once the chainsaw starts, but keep the trigger pressed for continuous operation.
5.3 Cutting Techniques
- Hold the chainsaw firmly with both hands.
- Ensure a stable footing and clear work area.
- Allow the chain to reach full speed before contacting the material to be cut.
- Apply light, consistent pressure. Do not force the chainsaw through the material.
- Be aware of kickback, especially when cutting with the tip of the guide bar.

6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your chainsaw.
6.1 Cleaning
- Always remove the battery before cleaning.
- Use the provided cleaning brush to remove sawdust, debris, and oil residue from the guide bar, chain, and motor housing.
- Wipe down the exterior with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
6.2 Chain Sharpening
A sharp chain is crucial for efficient and safe cutting. Sharpen the chain regularly or replace it when dull. Refer to the chain manufacturer's guidelines for proper sharpening angles and tools.

6.3 Storage
Store the chainsaw in a dry, secure location, out of reach of children. Remove the battery before storage. If storing for an extended period, ensure the battery is partially charged (around 50%) and stored separately in a cool, dry place.
