4. Fuel Safety: Refuel outdoors only when engine is cold. Use fuel/oil mix as specified.

WARNING! Chainsaws are dangerous tools. Improper use can cause serious injury or death. Always follow safety procedures.

Assembly & Preparation

Unpack and inspect contents. Assemble following these steps:

1. Attach guide bar and chain: Place bar on studs, fit chain with cutting teeth facing forward, tighten bar nuts finger-tight.
2. Tension chain: Use side-mounted tensioner to achieve proper tension (chain should snap back when pulled from bar).
3. Fill with fuel: Mix high-quality 2-stroke oil with unleaded gasoline (50:1 ratio for Husqvarna XP oil).
4. Fill chain oil: Use quality bar and chain oil in separate tank.
5. Check controls: Ensure throttle trigger, throttle lockout, and chain brake function properly.

CAUTION! Never operate without proper chain tension and lubrication.

Operating Instructions

Proper cutting techniques for safety and efficiency.

1. Basic Stance: Stand with feet shoulder-width apart, left foot slightly forward.
2. Grip: Hold front handle with left hand, rear handle with right hand. Thumbs wrapped around handles.
3. Starting Cut: Apply light pressure, let chain do the work. Avoid forcing the saw.
4. Kickback Prevention: Never cut with upper quadrant of bar tip. Be aware of pinch points.
5. Bucking: Support log properly. Cut from top down for supported logs, from bottom up for unsupported.
6. Limbing: Work from trunk outward. Be aware of spring-loaded branches.
7. Felling: Not recommended for inexperienced users. Requires proper planning and techniques.

Tip: Maintain sharp chain and proper tension for best performance.

Maintenance Schedule

Chain & Bar Care

Proper maintenance extends life of cutting equipment.

1. Sharpening: Use round file matching chain pitch. Maintain 30° cutting angle, 10° top plate angle.
2. Depth Gauges: File down to 0.65 mm below cutting tooth. Use depth gauge tool.
3. Bar Maintenance: Clean bar groove weekly. File rails flat when worn. Rotate bar weekly for even wear.
4. Lubrication: Always use quality bar and chain oil. Check oil flow before each use.
5. Tension: Proper tension when chain is warm. Should snap back when pulled from bar.

CAUTION! Always wear gloves when handling chain. Chain is extremely sharp.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Short-term (under 30 days): Fill fuel tank, add fuel stabilizer, run for 2 minutes.
2. Long-term (over 30 days): Drain fuel tank completely. Run engine until it stops.
3. Chain: Remove, clean, and soak in oil. Store in oiled cloth.
4. Bar: Clean, oil rails, store flat.
5. General: Clean entire saw. Store in dry place, protected from moisture.

WARNING! Never store with fuel in tank for extended periods without stabilizer.
