Operating Instructions

Techniques for efficient and safe cutting.

1. Hold saw firmly: Left hand on front handle, right on rear, thumbs wrapped.
2. Basic cutting: Let chain do the work; avoid forcing bar into wood.
3. Bucking: Support log; cut from top; avoid pinching bar.
4. Limbing: Stand to left of saw; cut downward from top of limb.
5. Maintain speed: Keep engine at full throttle during cuts.

Tip: Plan escape path free of obstacles before cutting.

Maintenance Schedule

Regular maintenance ensures longevity and safety.

Chain & Bar Care

Proper chain maintenance ensures cutting efficiency and safety.

1. Sharpening: Use round file matching chain pitch; maintain correct filing angle (typically 30°).
2. Tensioning: Adjust when chain sags from bottom of bar; chain should snap back when pulled.
3. Bar maintenance: Clean bar groove regularly; flip bar monthly for even wear.
4. Lubrication: Always use recommended chain oil; check oil flow before cutting.

WARNING! Always wear gloves when handling chain. Stop engine before adjustments.

Carburetor Adjustment

Factory settings typically require no adjustment. Only adjust if necessary.

Adjustment screws: L (low speed), H (high speed), T (idle).

1. Warm up engine fully.
2. Set idle speed (T): Adjust so chain does not move at idle.
3. Low speed (L): Turn until engine runs smoothly at low RPM.
4. High speed (H): Do not adjust beyond factory setting (risk of engine damage).

CAUTION! Excessive leaning of H screw can cause engine seizure. Consult dealer if unsure.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Empty fuel tank or add fuel stabilizer; run engine 2 minutes to circulate.
2. Clean entire saw; remove sawdust from cooling fins and air filter.
3. Remove chain and bar; clean and oil thoroughly.
4. Store in dry, cool place, protected from dust and moisture.

CAUTION! Never store with fuel in tank for more than 30 days without stabilizer.
