Setup
1. Chain and Guide Bar Installation
The Oregon CS1200 is designed for easy assembly. Follow the instructions provided in the packaging for mounting the guide bar and chain. Ensure the chain is correctly seated in the guide bar groove and the drive sprocket.
2. Filling Chain Lubricant
The chainsaw features an automatic lubrication system. Before each use, ensure the oil tank is filled with appropriate chain lubricant. Use only high-quality chain oil to ensure proper lubrication and extend chain life.

- Unscrew the oil tank cap.
- Carefully pour chain lubricant into the tank until it reaches the MAX level on the indicator.
- Replace the cap securely.
- Periodically check the oil level during operation using the transparent indicator.
3. Adjusting Chain Tension
Correct chain tension is crucial for safe and efficient operation. The CS1200 features a tool-free tensioning system.

- Ensure the chainsaw is unplugged.
- Loosen the large red outer knob on the side cover.
- Turn the smaller red inner knob clockwise to increase tension, or counter-clockwise to decrease tension.
- The chain is correctly tensioned when it can be pulled away from the guide bar by about 2-3 mm at the center, but still snaps back into place.
- Tighten the large red outer knob securely.
Operating Instructions
1. Starting the Chainsaw
- Ensure the chain brake is disengaged (pulled back towards the front handle).
- Connect the chainsaw to a suitable power outlet (230V).
- Grip the front handle with your left hand and the rear handle with your right hand.
- Press the safety lock-off button with your thumb, then squeeze the trigger switch. The chain will start moving.
2. Cutting Techniques
Always plan your cut before starting. Ensure stable footing and a clear escape path. When cutting, let the chainsaw do the work; do not force it. Apply light pressure and allow the chain to cut through the material. Be mindful of pinching and kickback.

3. Stopping the Chainsaw
Release the trigger switch. The chain will stop quickly due to the integrated chain brake. For complete power disconnection, unplug the chainsaw from the power outlet.
Maintenance
Regular maintenance ensures the longevity and safe operation of your chainsaw.
- Chain Lubrication: The automatic system requires regular refilling of the oil tank. Always use Oregon chain oil or equivalent.
- Chain Sharpening: A sharp chain is essential for efficient cutting and safety. Sharpen the chain regularly or replace it when dull. Refer to Oregon's guidelines for sharpening the 91PJ chain.
- Chain and Guide Bar Inspection: Regularly check the chain for damage, wear, and proper tension. Inspect the guide bar for wear, especially on the rails.
- Cleaning: After each use, clean sawdust and debris from the motor housing, guide bar, and chain. Ensure cooling vents are clear.
- Storage: Store the chainsaw in a dry, secure place, out of reach of children. Ensure the chain brake is engaged and the power cord is safely stored.
