Safety Instructions
Always prioritize safety when operating power tools and accessories. Failure to follow these safety guidelines may result in serious injury or property damage.
- Read All Instructions: Familiarize yourself with both this guide and your chainsaw's instruction manual before use.
- Wear Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, gloves, and sturdy footwear. Consider a hard hat and leg protection (chaps) when operating a chainsaw.
- Ensure a Stable Work Area: Work on a level, clear surface. Secure the log to prevent movement during cutting.
- Inspect Equipment: Before each use, check the cutting guide and chainsaw for any damage, loose parts, or wear. Ensure all fasteners are tight.
- Maintain Proper Grip: Always maintain a firm grip on your chainsaw with both hands.
- Keep Bystanders Away: Ensure a safe distance between the work area and any bystanders, children, or pets.
- Avoid Kickback: Be aware of potential chainsaw kickback. Do not cut with the tip of the guide bar.
- Never Operate Under Influence: Do not operate machinery while fatigued or under the influence of drugs or alcohol.

Setup
Follow these steps to assemble and prepare your cutting guide for use:
- Unpack Components: Carefully remove all parts from the packaging and verify against the package contents list.
- Assemble the Guide:
- Disassemble the chainsaw clamp components if they are pre-assembled.
- Insert the main rod of the chainsaw clamp through the designated holes in the guide's frame.
- Secure the clamp components and tighten all screws using the provided hex wrench. Ensure all nuts are anti-loosening nuts and are securely fastened to prevent movement during operation.
- Attach to Chainsaw:
- Position the cutting guide onto your chainsaw's guide bar.
- Secure the chainsaw clamp firmly to the guide bar. Ensure the clamp is tight and the guide is stable on the chainsaw.
- Adjust Cutting Width: The guide allows for adjustable cutting widths from 5 to 15 cm (2 to 6 inches). Adjust the position of the guide on the log to achieve your desired board thickness.


Operating Instructions
Once the guide is assembled and attached to your chainsaw, follow these steps for operation:
- Prepare the Log: Ensure the log is securely positioned and stable. For the first cut, you may need to create a flat surface on the log for the guide to rest on, or use an auxiliary guide rail.
- Position the Guide: Place the cutting guide onto the log, ensuring it is stable and aligned for your desired cut. The guide's frame should rest firmly on the log's surface.
- Start the Chainsaw: Following your chainsaw's safety instructions, start the engine/motor.
- Begin Cutting: With the chainsaw running at full speed, slowly and steadily push the chainsaw and guide through the log. Maintain consistent pressure and speed for a smooth, even cut.
- Maintain Control: Keep both hands firmly on the chainsaw handles. Be prepared for the chainsaw to pull or push during the cut.
- Complete the Cut: Continue through the entire length of the log. Once the cut is complete, turn off the chainsaw and allow the chain to stop before removing the guide.
- Repeat for Additional Boards: Reposition the guide for subsequent cuts to create multiple boards of desired thickness.


Maintenance
Regular maintenance ensures the longevity and safe operation of your cutting guide.
- Cleaning: After each use, clean the guide to remove sawdust, resin, and debris. Use a brush or compressed air. Avoid harsh chemicals that may damage the finish.
- Inspection: Periodically inspect all bolts, nuts, and clamps for tightness. Re-tighten any loose fasteners. Check for any signs of wear, bending, or damage to the frame or clamp components.
- Storage: Store the cutting guide in a dry, clean place, away from direct sunlight and extreme temperatures.
- Chainsaw Maintenance: Always follow your chainsaw manufacturer's maintenance schedule, including chain sharpening, oiling, and air filter cleaning, as a dull chain or poorly maintained saw will affect cutting performance and safety.

Troubleshooting
If you encounter issues during operation, refer to the following common problems and solutions:
- Uneven Cuts:
- Ensure the log is stable and not shifting during the cut.
- Verify that the cutting guide is securely clamped to the chainsaw bar and all fasteners are tight.
- Check if the chainsaw chain is sharp and properly tensioned. A dull or loose chain can cause uneven cuts.
- Maintain consistent pressure and speed throughout the cut.
- Difficulty Pushing Through Log:
- The chainsaw chain may be dull. Sharpen or replace it.
- Ensure the chainsaw is operating at full RPM.
- Check for binding in the cut. The log may be pinching the bar. Use wedges if necessary.
- Guide Feels Loose or Wobbly:
- Re-tighten all bolts and nuts on the guide and the chainsaw clamp.
- Ensure the chainsaw bar is properly seated in the clamp.
