Below are key sections for safety, features, assembly, operation, maintenance, and troubleshooting.

Features at a Glance

Key components: X-Torq engine, inertia-activated chain brake, combined choke/stop control, side-mounted chain tensioner, ergonomic handles with anti-vibration system.

Assembly & Preparation

Unpack and inspect all contents. Assemble on a clean, stable surface.

1. Attach guide bar and chain: Place bar on mounting studs, fit chain, tighten bar nuts finger-tight.
2. Adjust chain tension: Use side tensioner to achieve proper tension (check manual for specs).
3. Fill with fuel: Use fresh, high-quality gasoline mixed with 2-stroke oil (50:1 ratio).
4. Fill chain oil: Use recommended bar and chain oil in separate tank.

WARNING! Always wear protective gear (gloves, eye protection, hearing protection, chainsaw chaps, helmet) during assembly and operation. Ensure chain brake is engaged when not cutting.

First-Time Operation

Perform pre-start checks before first use.

1. Check chain tension: Chain should be snug against bar but pull freely.
2. Check chain sharpness: Ensure chain is properly sharpened.
3. Start the saw: Place on ground, engage chain brake, set choke, pull starter cord until engine fires, then disengage choke and pull again.
4. Warm up: Allow engine to idle for 30 seconds before cutting.

CAUTION! Never start the saw unless bar and chain are properly assembled and chain brake is engaged. Keep bystanders at least 15 feet away.

Safe Operation Procedures

Always follow safe cutting practices to prevent injury.

1. Personal Protective Equipment (PPE): Always wear helmet, eye protection, hearing protection, gloves, chainsaw chaps, and steel-toed boots.
2. Clear work area: Remove tripping hazards and ensure safe escape path.
3. Proper stance: Stand with feet shoulder-width apart, left foot slightly forward.
4. Cutting techniques: Use lower quadrant of bar; avoid tip contact to prevent kickback.
5. Refueling: Stop engine and allow to cool before refueling.

Tip: Never operate chainsaw above shoulder height or with one hand.

Maintenance Schedule

Regular maintenance ensures optimal performance and longevity.

1. Daily: Check chain tension and sharpness, clean air filter, check bar and chain oil level.
2. Weekly: Clean cooling fins, check spark plug, clean fuel filter.
3. Monthly: Clean carburetor air intake, check all nuts and bolts for tightness.
4. Seasonally: Replace spark plug, clean exhaust port and screen, inspect anti-vibration elements.
5. Annually: Professional servicing recommended.

WARNING! Always disconnect spark plug wire before performing maintenance. Use only genuine Husqvarna replacement parts.

Chain & Bar Care

Proper chain and bar maintenance is critical for safe operation.

1. Sharpening: Use correct file size (typically 5/32" or 3/16") and maintain proper filing angle (typically 30°).
2. Depth gauges: File depth gauges to proper height (0.025" below cutter tip).
3. Bar maintenance: Clean bar groove regularly, flip bar weekly for even wear.
4. Lubrication: Always use recommended bar and chain oil; adjust oil flow according to conditions.

CAUTION! A dull chain increases kickback risk and operator fatigue. Replace chain when cutters are worn beyond repair.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Short-term (under 30 days): Empty fuel tank or add fuel stabilizer.
2. Long-term: Empty fuel tank completely, run engine until it stops. Remove chain and bar, clean and oil them. Store in dry place.
3. Battery (if electric start): Remove battery and store in cool, dry place.

CAUTION! Never store chainsaw with fuel in tank for extended periods without stabilizer. Store out of reach of children.
