3. Assembly

Before assembly, ensure the battery is removed from the chainsaw.

3.1 Attaching the Chain and Guide Bar:

1. Prepare the Chain: Carefully uncoil the chain and place it on a flat surface. Note the direction of the cutting teeth; they should face forward, away from the chainsaw body.
2. Remove Cover Plate: Turn the green knob counter-clockwise to loosen and remove the cover plate from the chainsaw body.
3. Install Chain on Guide Bar: Place the chain onto the guide bar, ensuring the cutting teeth are oriented correctly.
4. Mount Guide Bar and Chain: Position the guide bar with the chain onto the chainsaw body. Ensure the mounting plate faces upwards and the chain engages with the drive sprocket.
5. Reattach Cover Plate: Place the cover plate back onto the chainsaw body. Do not fully tighten the green knob yet.

3.2 Adjusting Chain Tension (Tool-Free):

The SEYVUM chainsaw features a tool-free chain tensioning system for easy adjustments.

1. Loosen Cover Plate: If the chain is too tight, first turn the green knob counter-clockwise to loosen the cover plate slightly.
2. Adjust Tension: Rotate the black ring clockwise to tighten the chain or counter-clockwise to loosen it. The chain should be snug against the guide bar, but still allow you to pull it slightly away from the bar (approximately 2-3mm).
3. Secure Cover Plate: Once the desired tension is achieved, turn the green knob clockwise to firmly tighten the cover plate.

5.3 Cutting Techniques:

• Always maintain a balanced stance and firm grip.
• Allow the chainsaw to reach full speed before contacting the wood.

• Be aware of potential kickback and pinch points.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your chainsaw.

6.1 Chain Tension:

Check chain tension frequently, especially during extended use. A properly tensioned chain should be snug but still allow for slight movement away from the guide bar. Refer to Section 3.2 for adjustment instructions.

6.2 Oiling:

Always ensure the oil reservoir is filled with appropriate bar and chain oil before and during operation. Check the oil level regularly using the oil level window.

6.3 Cleaning:

• Remove the battery before cleaning.
• Use a brush or compressed air to remove sawdust and debris from the chain, guide bar, and motor housing.
• Wipe down the exterior with a damp cloth. Do not use harsh chemicals.

6.4 Chain Sharpening:

A sharp chain is crucial for efficient and safe cutting. If the chain becomes dull, it should be sharpened or replaced. Consult a professional or refer to specific chain sharpening guides for your chain type.
