5.2. Saw Chain and Rail Installation/Adjustment

The Makita DUC122RTE features tool-free chain adjustment.

1. Ensure the battery is removed from the chainsaw before handling the chain or rail.
2. Loosen the chain tension adjustment knob (refer to Image 5) by turning it counter-clockwise.

4. Position the guide bar onto the chainsaw body.
5. Tighten the chain tension adjustment knob clockwise until the chain is snug but can still be pulled freely around the guide bar by hand. The chain should not sag on the underside of the guide bar.

3. Replace the cap securely.
4. One battery charge is approximately sufficient for one oil tank filling.

6. Operating Instructions

Always ensure you are wearing appropriate PPE and have received special training before operating this top handle chainsaw.

6.1. Starting the Chainsaw

1. Ensure the battery is fully charged and securely installed.
2. Hold the chainsaw firmly with both hands.
3. Disengage the chain brake by pulling the front hand guard towards the front handle until it clicks.
4. Press the lock-off button (if present) and then squeeze the trigger switch to start the motor.
5. Release the lock-off button once the motor is running.

6.2. Cutting Techniques

Always follow safe cutting practices. Avoid cutting above shoulder height. Maintain a stable stance and be aware of kickback potential.

• Limbing: When limbing, support the branch to prevent pinching the saw chain.
• Felling: For felling operations, follow established safety guidelines for directional felling and escape routes.
• Avoid Kickback: Be aware of the kickback zone at the tip of the guide bar. Avoid contact with this area.

6.3. Engaging the Chain Brake

The engine brake stops the saw chain within 0.5 seconds. To engage the chain brake, push the front hand guard forward until it clicks into place. This should be done immediately after completing a cut or in an emergency.

7. Maintenance

Regular maintenance ensures the longevity and safe operation of your chainsaw.

• Chain Lubrication: Regularly check the chain oil level and refill as needed. The automatic lubrication system requires a full oil tank for optimal performance.
• Chain Sharpening: Keep the saw chain sharp using the provided file (4) or a suitable sharpening tool. A sharp chain cuts efficiently and reduces the risk of kickback.
• Chain Tension: Periodically check and adjust chain tension. A loose chain can derail, and an overly tight chain can cause premature wear.
• Cleaning: After each use, clean the chainsaw body, guide bar, and chain to remove sawdust, sap, and debris. Ensure ventilation openings are clear.
• Storage: Store the chainsaw in its transport case in a dry, secure location, out of reach of children and untrained individuals. Remove the battery before storage.
