1. Introduction
This manual provides essential instructions for the safe and effective assembly, operation, and maintenance of your Granberg G777 Chainsaw Alaskan Small Log Mill. Please read all instructions thoroughly before use to ensure proper function and personal safety.
2. Safety Information
WARNING: Chainsaws and milling equipment can be dangerous. Always follow manufacturer safety guidelines for both your chainsaw and the mill. Failure to do so may result in serious injury or death.
2.1 Personal Protective Equipment (PPE)
Head Protection: Wear a hard hat with a face shield.
Ear Protection: Use ear muffs or earplugs to prevent hearing damage.
Eye Protection: Wear safety glasses or goggles under your face shield.
Hand Protection: Wear heavy-duty work gloves.
Leg Protection: Always wear chainsaw chaps to protect against chain contact.
Foot Protection: Wear sturdy work boots with steel toes.
2.2 General Safety Precautions
Ensure all fasteners on the mill are securely tightened before each use.
Operate the chainsaw at full RPM during milling to ensure clean cuts and prevent stalling.
Use a ripping chain for optimal performance and smoother cuts when milling.
Inspect logs for foreign objects (nails, rocks, etc.) and remove bark where cuts will be made to prevent damage to the chain and potential kickback.
Use wedges to prevent the log from pinching the chainsaw bar during cuts. Insert wedges lightly to avoid altering the cut accuracy.
Maintain a clear work area, free from obstructions and bystanders.
Never operate the chainsaw mill under the influence of drugs or alcohol.

4. Setup and Assembly
The Granberg G777 mill is designed for easy assembly. Follow these steps to attach it to your chainsaw:
Attach Uprights: Secure the vertical uprights to the main aluminum frame using the provided bolts and anti-loose nuts. Ensure large washers are used to prevent loosening during operation.
Install Handle: Attach the handle to the mill frame. The handle is designed to slide, allowing for proper positioning during milling.
Mount to Chainsaw Bar: The mill clamps onto your chainsaw bar without requiring drilling. Position the mill so that the chainsaw bar is centered between the mill's clamping brackets.
Secure Clamps: Tighten the bolts on the clamping brackets to firmly secure the mill to the chainsaw bar. Use a small ratcheting torque wrench to ensure proper torque settings (10-12 lbs max) to avoid bending the saw bar. Ensure the chain is free to move and not touching any part of the mill.
Adjust Depth: Use the marked inches and millimeters on the uprights to set your desired cutting thickness.
Install Safety Guard: Attach the polycarbonate safety guard to the mill.

5. Operating Instructions
Milling lumber requires careful technique to achieve straight and even cuts. The Granberg G777 is designed for ease of use, but practice is recommended.
5.1 First Cut Setup
For the first cut, a guide rail system is essential to ensure a straight initial surface. This can be a dedicated rail system (e.g., Granberg Easy-Rails), an aluminum ladder, or a straight 2x8 board securely attached to the log.

5.2 Milling Technique
Start the Chainsaw: Ensure the chainsaw is running at full RPM before engaging the chain with the wood.
Maintain Even Pressure: Apply steady, even forward pressure on the mill. Avoid forcing the saw, as this can lead to stalling, poor cut quality, and damage to the chainsaw clutch. The saw should pull itself into the log.
Support the Powerhead: When exiting a cut, especially at the end of the log, apply slight upward pressure on the upright handle to prevent the mill from dipping and creating an uneven finish.
Use Wedges: As you progress through the cut, insert wooden or plastic wedges into the kerf (the cut opening) behind the chainsaw bar. This prevents the log from closing in and pinching the bar, which can cause kickback or chain damage.
Monitor Sawdust: Observe the sawdust being produced. Consistent, fine sawdust indicates a good cut. Large chips or excessive dust may indicate an issue with the chain or technique.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Granberg G777 mill and chainsaw.
Clean After Each Use: Remove all sawdust and debris from the mill frame, clamps, and chainsaw.
Inspect Fasteners: Periodically check all nuts and bolts for tightness. Re-tighten as necessary to prevent vibration and ensure structural integrity.
Chainsaw Maintenance: Follow your chainsaw manufacturer's guidelines for chain sharpening, bar maintenance, and engine servicing. A sharp chain is crucial for efficient and safe milling.
Lubrication: Ensure your chainsaw's bar and chain oil reservoir is full before each use.
