4. Kickback Prevention: Hold saw firmly with both hands; avoid contact with bar tip.
5. Chain Brake: Test before each use; engage when carrying or not cutting.

WARNING! Failure to follow safety instructions may result in serious injury or death. Never operate when tired or under influence.

Assembly & Preparation

Unpack and inspect all parts. Assemble on clean, flat surface.

1. Attach Guide Bar: Place bar onto mounting studs; align chain with sprocket; install bar nuts finger-tight.
2. Install Chain: Ensure cutting teeth face forward on top of bar; adjust tension.
3. Fuel Mix: Use fresh unleaded gasoline (minimum 89 octane) mixed with 2-stroke oil at 50:1 ratio.
4. Fill Oil Reservoir: Use high-quality bar and chain oil; check level before each use.
5. Final Check: Verify all fasteners are tight; chain moves freely; safety features functional.

CAUTION! Do not force components during assembly. Use only Oleo Mac recommended parts.

Starting & Operating

Cold Start Procedure:

1. Place saw on flat ground; engage chain brake.
2. Set master control to CHOKE position; press primer bulb 5-6 times.
3. Pull starter rope sharply until engine fires (1-3 pulls).
4. Move control to FAST IDLE position; pull until engine starts.
5. Disengage chain brake; squeeze throttle to return to idle.

Cutting Techniques: Use lower quadrant of bar for cutting; maintain firm grip; let chain do the work. Never cut above shoulder height.

Tip: Allow engine to warm up 30 seconds before cutting. Always cut at full throttle.

Maintenance & Cleaning

Daily maintenance ensures optimal performance and longevity.

1. After Each Use: Clean air filter; check chain tension; clean saw of debris.
2. Weekly: Check spark plug; clean cooling fins; inspect bar for wear.
3. Monthly: Clean fuel filter; check fuel lines; clean carburetor air passage.
4. Seasonal: Replace spark plug; clean exhaust port; check anti-vibration elements.

WARNING! Always disconnect spark plug wire before performing maintenance. Use only genuine Oleo Mac parts.

Chain Sharpening & Replacement

Sharp chain improves cutting efficiency and safety.

1. Chain Removal: Loosen bar nuts; remove bar cover; lift bar to remove chain.
2. Sharpening: Use round file matching chain pitch (typically 3/8" or 0.325"); maintain 30° angle.
3. Depth Gauge: File rakers to 0.65 mm below cutter height.
4. Reinstallation: Place chain on bar; install bar; adjust tension until chain snaps back when lifted.
5. Test: Run chain briefly without cutting; recheck tension after warm-up.

CAUTION! Wear heavy gloves when handling chain. Replace chain when cutters are worn to 4 mm.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Short-term (under 30 days): Add fuel stabilizer; run engine 2 minutes to circulate.
2. Long-term: Drain fuel tank and carburetor; run until engine stops. Remove chain; clean and oil. Store in dry, cool place away from children.
3. Bar & Chain: Clean thoroughly; coat with oil; store separately if possible.

CAUTION! Never store with fuel in tank for more than 30 days. Fuel deteriorates and damages carburetor.
