Features at a Glance

Key components: Gas-powered engine, guide bar, cutting chain, automatic oiling system, safety features, and ergonomic handles.

Safety Information

Read all safety instructions before operation. Always wear protective gear.

1. Personal Protective Equipment (PPE): Wear safety glasses, hearing protection, gloves, chainsaw chaps, and steel-toed boots.
2. Clear Work Area: Ensure no bystanders, pets, or obstacles within 15 feet.
3. Inspect Chainsaw: Check for loose parts, chain tension, and fuel/oil leaks before each use.
4. Proper Grip: Hold with both hands, right hand on rear handle, left on front.
5. Kickback Awareness: Be aware of kickback zone (upper quadrant of bar tip).

WARNING! Never operate a chainsaw while tired, under the influence, or in poor weather conditions. Keep children away.

Assembly & Setup

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

1. Attach Guide Bar & Chain: Place bar on mounting studs, align chain with sprocket, adjust tension.
2. Fill Fuel Tank: Use fresh gasoline mixed with 2-cycle oil (50:1 ratio recommended).
3. Fill Bar & Chain Oil: Use recommended bar and chain oil in separate reservoir.
4. Check Chain Tension: Chain should snap back when pulled from bar; adjust if loose.
5. Test Safety Features: Verify chain brake and throttle lockout function properly.

CAUTION! Fuel is flammable; fill outdoors away from ignition sources. Avoid skin contact with fuel/oil.

Controls and Components

Main components: Front handle with chain brake, rear handle with throttle trigger, throttle lockout, choke, primer bulb, stop switch, and fuel/oil caps.

Controls: Throttle trigger (accelerates engine), throttle lockout (must be pressed to engage throttle), choke (for cold starts), primer bulb (pumps fuel to carburetor), stop switch (stops engine), chain brake lever (manual activation).

Maintenance points: Air filter cover, spark plug, chain tensioner, bar mounting nuts, oiler adjustment (if equipped).

Operation Instructions

Starting procedure, cutting techniques, and shutdown.

1. Starting: Place on ground, engage chain brake, set choke, press primer 3-5 times, pull starter cord until engine fires, move choke to run, pull again to start.
2. Cutting: Let engine warm up. Use full throttle when cutting. Do not force saw; let chain do the work.
3. Bucking & Limbing: Use proper techniques for cutting fallen logs (bucking) and removing branches (limbing).
4. Shutdown: Release throttle, allow chain to stop, engage chain brake, press stop switch.

Tip: Plan escape path before cutting. Never cut above shoulder height.

Maintenance & Care

Regular maintenance ensures performance and longevity.

1. Daily: Clean air filter, check chain tension and sharpness, inspect for damage.
2. Weekly: Clean cooling fins, check spark plug, clean guide bar groove.
3. Monthly: Replace fuel filter, clean carburetor (if needed), check all fasteners.
4. Seasonally: Replace spark plug, clean exhaust screen, inspect anti-vibration elements.

WARNING! Perform maintenance only when engine is cool and spark plug wire disconnected.

Chain Sharpening & Tensioning

Proper chain maintenance is critical for safety and performance.

1. Sharpening: Use round file matching chain pitch. Maintain 30° filing angle. File each cutter evenly.
2. Tensioning: Chain should be snug against bar but pull freely. Adjust when cool using tool-less tensioner or wrench.
3. Depth Gauges: File depth gauges (rakers) periodically to maintain proper height relative to cutters.

CAUTION! Wear gloves when handling chain. Replace chain if damaged or excessively worn.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Short-term (under 30 days): Drain fuel or add fuel stabilizer, run engine to distribute.
2. Long-term: Drain all fuel, run engine until it stops. Remove chain, clean and oil it. Store in dry place.
3. Bar & Chain: Clean, oil, and store separately in sealed container.

CAUTION! Store fuel in approved container away from living areas. Do not store chainsaw with fuel in tank indoors.
