5. Operating Instructions
Follow these steps for safe and effective operation of your sawmill.
5.1 Pre-Operation Checklist
- Ensure all safety guards are in place.
- Check engine oil and fuel levels.
- Verify blade tension and sharpness.
- Confirm the work area is clear.
- Wear all required PPE.
5.2 Starting the Engine
- Engage the choke (if cold).
- Turn the ignition key to the 'ON' position.
- Press the electric start button until the engine starts.
- Once started, disengage the choke gradually.
5.3 Loading Logs
- Carefully roll or lift the log onto the track bunks.
- Position the log securely using the log clamps. Ensure the log is stable and will not shift during cutting.
5.4 Adjusting Cutting Depth and Making Cuts
- Use the board thickness adjustment handle and precision ruler to set the desired cutting depth.
- Start the engine and allow it to reach operating speed.
- Slowly advance the saw head through the log using the throttle control handle to manage cutting speed. Do not force the cut.
- After each pass, return the saw head to the starting position, adjust the cutting depth for the next board, and repeat the process.

6.2 Engine Maintenance
- Oil Changes: Follow the engine manufacturer's recommendations for oil change intervals.
- Air Filter: Clean or replace the air filter regularly, especially when operating in dusty conditions.
- Spark Plug: Inspect and clean the spark plug periodically. Replace if worn.
- Fuel System: Drain the fuel system if storing the sawmill for an extended period.
6.3 Track and Component Cleaning
- Keep the track system free of sawdust, debris, and resin buildup to ensure smooth movement of the saw head.
- Lubricate moving parts as recommended in the engine manual or assembly guide.
- Inspect all bolts and fasteners regularly and tighten as necessary.
7. Troubleshooting
This section addresses common issues you might encounter with your sawmill.
