3. Inspect Chainsaw: Check for loose parts, chain tension, and damage before each use.
4. Proper Handling: Hold with both hands, maintain secure footing, and never operate above shoulder height.
5. Kickback Awareness: Be aware of the kickback zone (upper quadrant of bar tip).

WARNING! Chainsaws are dangerous tools. Failure to follow safety guidelines can result in serious injury or death. Keep hands away from moving chain.

Assembly & Setup

Unpack and inspect all parts. Assembly requires basic tools.

1. Attach Guide Bar & Chain: Place bar on mounting studs, loop chain around bar with cutting teeth facing forward, adjust tension.
2. Install Hand Guard: Secure front hand guard to bar cover.
3. Fill Oil Reservoir: Use bar and chain oil (not motor oil) to lubricate chain.
4. Fuel Mix Preparation: Mix 2-cycle engine oil with unleaded gasoline (50:1 ratio). Shake well.
5. Final Check: Ensure all nuts and bolts are tight, chain moves freely, and safety features function.

CAUTION! Use only recommended fuels and oils. Improper mixture can damage engine.

Operation: Engage chain brake before starting. Use choke for cold starts. Release throttle lockout before pulling trigger.

Fuel & Oil Requirements

Use proper fuel mix and lubrication oils.

1. Fuel: Fresh unleaded gasoline with minimum 89 octane. Mix with 2-cycle engine oil at 50:1 ratio (2.6 oz oil per gallon of gas).
2. Bar & Chain Oil: Use high-quality, non-detergent oil with tackifiers. Do not use used motor oil.
3. Storage: Use fuel stabilizer if storing over 30 days. Empty fuel tank for long-term storage.

Tip: Always mix fuel in approved container. Never mix directly in chainsaw tank.

Starting & Operating

Follow proper starting procedure for safe operation.

1. Pre-Start Check: Ensure chain brake is engaged, chain tension is correct, area is clear.
2. Cold Start: Move switch to ON, set choke to FULL, press decompression valve, pull starter cord 3-4 times until engine fires. Move choke to HALF, pull until starts. Warm engine at idle.
3. Warm Start: Switch ON, choke OFF, pull starter cord.
4. Cutting Technique: Hold firmly with both hands. Let chain reach full speed before cutting. Use lower quadrant of bar for cutting. Do not force saw - let chain do the work.
5. Shutting Down: Release throttle, engage chain brake, move switch to OFF.

WARNING! Never drop-start chainsaw. Always maintain secure footing. Watch for kickback.

Maintenance Schedule

Regular maintenance ensures optimal performance and safety.

Chain Sharpening & Tensioning

Proper chain maintenance ensures efficient cutting and safety.

1. Chain Tensioning: Loosen bar nuts, adjust tensioning screw until chain snaps back when pulled from bar. Tighten bar nuts while lifting bar tip.
2. Sharpening: Use round file matching chain pitch (5/32" for 0.325" pitch). File each cutter at 30° angle. Maintain consistent depth gauge height.
3. Depth Gauges: File depth gauges with flat file to maintain 0.025" below cutter height.
4. Rotation: Rotate bar regularly to ensure even wear.

CAUTION! Always wear gloves when handling chain. Ensure chain brake is engaged during maintenance.

Storage Guidelines

Proper storage prevents damage and ensures ready operation.

1. Short-term (under 30 days): Add fuel stabilizer, run engine for 2 minutes to circulate treated fuel.
2. Long-term (over 30 days): Drain fuel tank completely, run engine until it stops. Drain bar oil tank. Remove chain, clean and oil it. Store in dry place.
3. Off-season: Perform complete maintenance. Store with cover in cool, dry location away from children.

WARNING! Never store chainsaw with fuel in tank for extended periods. Gasoline deteriorates and can damage engine.
