3.2 Filling the Chain Oil Reservoir
The DCCS623L1 features an auto-oiling system for continuous lubrication. It is crucial to keep the oil reservoir filled with appropriate bar and chain oil.
- Place the chainsaw on a flat, stable surface.
- Unscrew the oil reservoir cap.
- Carefully pour bar and chain oil into the reservoir until it reaches the maximum fill line. Do not overfill.
- Replace the oil reservoir cap securely.
- Periodically check the oil level during operation and refill as needed.

3.3 Adjusting Chain Tension
Correct chain tension is vital for safe and efficient operation. A loose chain can derail, and a too-tight chain can cause excessive wear and reduce performance.
- Ensure the battery is removed for safety.
- Locate the chain tensioning knob/screw on the side of the chainsaw.
- Turn the tensioning screw clockwise to tighten the chain or counter-clockwise to loosen it.
- The chain is correctly tensioned when it can be pulled away from the guide bar by approximately 1/8 to 1/4 inch (3-6 mm) at the center, but still snaps back against the bar when released.
- After adjusting, ensure all fasteners are secure.

4. Operating Instructions
4.1 Starting and Stopping the Chainsaw
- Ensure the battery is fully charged and properly installed.
- Hold the chainsaw firmly with both hands.
- Press the safety lock-off button with your thumb.
- Squeeze the trigger switch to start the chain. Release the trigger to stop the chain.
4.2 Cutting Techniques
Always maintain a firm grip with both hands. Position yourself to maintain balance and avoid kickback. The integrated tip guard is designed to provide stability during upcuts and reduce the risk of kickback.
- Pruning Branches: Support the branch if possible to prevent it from pinching the chain. Make relief cuts if necessary.
- Cutting Small Logs: Ensure the log is stable and cannot roll. Cut from the top down, allowing the weight of the chainsaw to assist.
- Avoid Kickback: Never cut with the tip of the guide bar. Always use the bottom or top edge of the bar. Be aware of branches under tension.
4.3 Operational Safety Precautions
- Do not operate the chainsaw with one hand unless specifically designed for it and you are trained. This model is designed for two-handed operation.
- Never operate the chainsaw above shoulder height.
- Keep the chain sharp and properly tensioned.
- Clear the work area of debris and ensure a stable footing.
- Do not force the chainsaw; let the tool do the work.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your chainsaw.
5.1 Cleaning
- Always remove the battery before cleaning.
- Use a stiff brush or compressed air to remove sawdust, chips, and debris from the motor housing, guide bar, and chain.
- Wipe down exterior surfaces with a damp cloth. Do not use solvents or harsh chemicals.
5.2 Chain Sharpening and Replacement
A sharp chain is essential for efficient cutting. If the chain becomes dull or damaged, it should be sharpened or replaced. Refer to your DEWALT service center or a qualified technician for chain sharpening or replacement if you are unsure.
5.3 Storage
When not in use, store the chainsaw in a dry, secure location out of reach of children. Ensure the chain cover is in place. Remove the battery before storing for extended periods.
