Safety Warnings & Precautions

Operating a chainsaw is inherently dangerous. Failure to follow safety instructions can result in serious injury or death.

Hazard	Precaution
Kickback	Always grip saw firmly with both hands. Use a low-kickback chain. Do not saw with the tip.
Contact with chain	Always engage chain brake before starting. Wear protective chaps and gloves.
Hearing damage	Wear approved hearing protection during operation.
Eye injury	Always wear safety glasses or a face shield.
Fire/Explosion	Refuel in a well-ventilated area with engine off and cool. Wipe spills immediately.
Carbon Monoxide	Operate only in well-ventilated outdoor areas.

Parts Identification & Assembly

Unpack all components and inspect for damage.

Handle Assembly: Attach rear handle to power unit using provided bolts. Tighten securely.
Guide Bar & Chain: Place bar onto mounting studs. Ensure chain direction is correct (cutting teeth forward on top). Adjust tension.
Chain Catcher & Hand Guard: Install safety components as per diagram.
Chain Brake: Test function by pushing forward hand guard towards bar.

WARNING! Do not operate the saw if any part is loose, damaged, or missing.

Fuel & Oil Mixture

The Homelite 330 uses a 2-stroke engine requiring a gasoline and oil mixture.

Fuel: Use fresh, unleaded gasoline with a minimum octane rating of 89.
Oil: Use a high-quality 2-stroke engine oil designed for air-cooled engines.
Mix Ratio: 50:1 (2.6 oz of oil per 1 gallon of gasoline). Mix thoroughly in a approved container.
Chain Oil: Fill separate reservoir with proper bar and chain oil. Do not use waste oil.

CAUTION! Never use automotive motor oil or straight gasoline. This will cause severe engine damage.

Starting & Stopping Procedure

Cold Start: Set chain brake ON. Move choke lever to FULL CHOKE. Press primer bulb 5-10 times. Pull starter rope sharply until engine 'pops'. Move choke to HALF CHOKE. Pull starter rope to start. Allow to idle briefly before releasing brake.
Warm Start: Set choke to RUN position. Pull starter rope.
Stopping: Release throttle trigger. Press and hold the STOP/ON/OFF switch until engine stops.

Operation & Cutting Techniques

Access OSD via TV MENU or SETUP (DVD). Front Panel: POWER, OPEN/CLOSE, AUTO/DPMS, MUTE.

Basic Stance: Stand with feet shoulder-width apart, left foot slightly forward. Firm two-handed grip.

Felling: Plan escape path. Make notch cut (1/3 tree diameter), then felling cut. Use wedges if needed.

Limbing & Bucking: Support log off ground. Cut from top side. Beware of pinch points.

Kickback Prevention: Maintain high saw speed in cut. Do not let moving chain contact any object except wood.

Chain & Bar Maintenance

Proper chain condition is vital for safety and performance.

Tension: Check when cold. Chain should snap back when pulled from bar. Adjust tensioning screw.
Sharpening: Use correct round file and guide. Maintain proper filing angle (typically 30°). File all cutters evenly.
Depth Gauges: File down depth gauges (rakers) with flat file to specified clearance.
Bar Care: Clean bar groove regularly. Flip bar each time chain is sharpened to ensure even wear.

Tip: A sharp chain reduces operator fatigue and kickback risk.

Engine Maintenance

Regular maintenance ensures reliability.

Component	Interval	Action
Air Filter	Every 10 hours	Clean with soap/water, dry thoroughly. Replace if damaged.
Spark Plug	Every season or 100 hrs	Clean electrodes, set gap to 0.025". Replace if worn.
Fuel Filter	Annually	Replace in-tank fuel filter.
Muffler & Spark Arrestor	Every 50 hours	Clean carbon deposits from screen.
External Surfaces	After each use	Wipe clean of sawdust and debris.

Carburetor Adjustment

Factory settings are optimal. Adjust only if necessary (high altitude, performance issues).

Idle Speed (L): Adjust so chain does not move at idle and engine accelerates smoothly.
High-Speed (H): Adjust for maximum power without 'four-stroking' (sputtering) at no-load.
Low-Speed (LA): Fine-tune for smooth transition from idle to high speed.

WARNING! Excessive leaning of H screw can cause engine overheating and seizure.

Storage Instructions

For storage longer than 30 days:

Drain fuel tank and run engine until it stops to clear carburetor.
Remove spark plug, add 1 tsp of engine oil into cylinder, pull starter slowly 2-3 times, reinstall plug.
Clean entire saw thoroughly.
Remove chain/bar, clean, and coat with oil. Store loosely.
Store in a dry, secure place, out of reach of children.

CAUTION! Storing with fuel can cause gumming of carburetor components.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine will not start	No spark, old fuel, flooded	Check spark plug. Use fresh fuel mix. Wait if flooded, start with throttle open.
Engine starts then dies	Clogged fuel filter, dirty air filter, carb adjustment	Replace fuel filter. Clean air filter. Check carburetor settings.
Engine lacks power	Dirty air filter, clogged muffler, dull chain	Clean air filter & spark arrestor screen. Sharpen chain.
Chain does not turn	Clutch worn, drive sprocket worn, chain brake engaged	Inspect clutch and sprocket. Disengage chain brake.
Chain throws oil	Oil port clogged, wrong oil viscosity	Clean oil ports on bar. Use correct bar & chain oil.
Excessive vibration	Loose components, unbalanced chain, bent bar	Tighten all bolts/nuts. Sharpen chain evenly. Replace bent bar.
