Assembly & Preparation

Unpack and inspect all contents. Ensure all parts are present and undamaged.

1. Assemble the guide bar and chain: Place bar on mounting studs, fit chain around sprocket and bar, adjust tension.
2. Fill with fuel: Use fresh, high-quality gasoline mixed with 2-stroke oil (50:1 ratio).

WARNING! Always wear protective gear (helmet, gloves, eye/ear protection, chainsaw chaps) during assembly and operation.

First-Time Use

Perform pre-start checks before first operation.

1. Check chain tension: Chain should be snug but pull freely around bar.
2. Check lubrication: Ensure chain oil is flowing to bar tip.

Operation Guidelines

Always maintain secure footing and grip. Plan escape path from falling tree or branches.

1. Starting: Follow cold/hot start procedure exactly.
2. Cutting: Use full throttle when cutting. Let chain do the work; don't force.
3. Kickback prevention: Keep saw body close to your body; avoid cutting with bar tip.
4. Refueling: Stop engine completely and allow to cool before refueling.

Tip: Regularly check chain sharpness; a sharp chain reduces effort and improves safety.

Maintenance Schedule

Daily or before each use: Check chain tension and sharpness, check chain lubrication, clean air filter, inspect guide bar for wear, check all nuts and bolts for tightness.

1. Weekly: Clean cooling fins, check spark plug condition, clean fuel filter.
2. Monthly: Clean carburetor air intake, check fuel lines for cracks, inspect anti-vibration elements.
3. Seasonally: Replace spark plug, clean muffler screen, check clutch and sprocket wear.
4. Annually: Have professional service check compression, carburetor adjustment, and overall condition.

WARNING! Always disconnect spark plug wire before performing any maintenance.

Chain & Bar Care

Proper chain maintenance is critical for performance and safety.

Sharpening: Use correct round file size for chain. Maintain correct filing angle (typically 30°). File all cutters to equal length. Check depth gauges regularly and file when needed.

Bar maintenance: Clean bar groove regularly. Flip bar periodically for even wear. Check for burrs on rails and file smooth. Ensure oil holes are clear.

Storage

For storage longer than 30 days, prepare saw properly.

1. Empty fuel tank and run carburetor dry.
2. Remove chain and bar; clean and oil them.
3. Clean entire saw of dirt, sawdust, and resin.
4. Store in dry, cool place, protected from dust.

CAUTION! Never store saw with fuel in tank for extended periods as it can damage carburetor components.
