4. Setup and Assembly
4.1 Installing the Guide Bar and Chain
- Ensure the chainsaw is unplugged from the power source.
- Remove the chain cover by loosening the tensioning knob.
- Place the chain around the sprocket and guide bar, ensuring the cutting edges face the correct direction.
- Fit the guide bar onto the mounting studs and ensure the chain is seated correctly in the guide bar groove.
- Replace the chain cover and lightly tighten the tensioning knob.
4.2 Adjusting Chain Tension
The Ryobi RCS1935B2C features a tool-free chain tensioner for quick and easy adjustment.
- With the chain cover lightly tightened, turn the tensioning knob to adjust the chain tension.
- The chain is correctly tensioned when it can be pulled freely around the guide bar by hand, but the drive links are still seated in the guide bar groove. There should be no excessive slack.
- Once tension is set, fully tighten the tensioning knob to secure the chain cover.
4.3 Filling the Chain Oil Reservoir
The chainsaw features an automatic oil pump and a visible oil level window.
- Ensure the chainsaw is unplugged.
- Place the chainsaw on a flat surface.
- Unscrew the oil reservoir cap.
- Fill the reservoir with high-quality chain and bar oil. The reservoir capacity is 200 ml.
- Monitor the oil level through the visible oil level window.
- Replace the oil reservoir cap securely.

5. Operating Instructions
5.1 Pre-Operation Checklist
- Ensure all safety gear is worn.
- Check chain tension.
- Verify oil reservoir is full.
- Inspect the power cord for damage.
- Ensure the chain brake is disengaged before starting.
5.2 Starting the Chainsaw
- Plug the chainsaw into a suitable power outlet.
- Hold the chainsaw firmly with both hands, one on the front handle and one on the rear handle.
- Press the safety switch (if applicable) and then squeeze the trigger to start the motor.
- Allow the chain to reach full speed before making contact with the wood.
5.3 Cutting Techniques
- Always maintain a firm grip and balanced stance.
- Use the metal bucking spike as a pivot point for leverage when cutting larger logs.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your chainsaw.
6.1 Chain Lubrication
The chainsaw features an automatic oil pump that continuously lubricates the chain and guide bar during operation. Regularly check the oil level through the visible oil level window and refill as needed. Use only recommended chain and bar oil.
6.2 Chain Sharpening
A sharp chain is crucial for efficient and safe cutting. A dull chain will produce fine sawdust instead of chips and require more force to cut. Refer to a specialized guide or professional service for proper chain sharpening techniques. The chain pitch is 3/8" and the gauge is 1.3 mm.
6.3 Cleaning
- Always unplug the chainsaw before cleaning.
- Remove sawdust and debris from the guide bar groove, chain, and motor housing.
- Clean the debris deflector to ensure proper function.
- Use a brush or compressed air for cleaning. Avoid using water directly on electrical components.
6.4 Storage
When not in use, store the chainsaw in a dry, secure location, out of reach of children. Ensure the chain brake is engaged and the guide bar cover is in place.
