Assembly & Preparation

Unpack and inspect all components. Assemble on clean, flat surface.

Attach guide bar: Remove side cover, align bar with sprocket, install chain with teeth facing forward.
Adjust chain tension: Loosen nuts, adjust tensioning screw until chain snaps back when pulled.
Install handle: Secure front and rear handles with provided bolts.
Fill fluids: Add 50:1 fuel/oil mixture to fuel tank; fill chain oil reservoir.

WARNING! Always wear protective gear during assembly. Ensure chain is properly tensioned before use.

First-Time Operation

Complete pre-operation checks before starting.

Safety check: Verify chain brake works, chain is properly tensioned, all guards are in place.
Starting procedure: Set choke to full, press primer bulb 5 times, pull starter cord until engine fires.
Warm-up: Allow engine to run at idle for 2-3 minutes before cutting.
Test cut: Make light cuts to ensure proper operation.

CAUTION! Never start chainsaw in enclosed area. Keep bystanders at least 15 feet away.

Safety: Chain brake activates automatically on kickback or manually by hand guard. Throttle lockout prevents accidental acceleration. Chain catcher prevents broken chain from striking operator.

Fuel & Lubrication

Use fresh unleaded gasoline (minimum 89 octane) mixed with 2-stroke oil at 50:1 ratio.

Fuel mixture: Pour 2.6oz of 2-stroke oil into 1 gallon of gasoline.
Chain oil: Use SAE 30 or special chain oil in reservoir.
Check oil flow: Run chainsaw over light surface; should see oil line on cut surface.
Storage: Drain fuel for long-term storage; run dry before storing.

Tip: Always shake fuel mixture before refueling. Never use automotive oil or straight gasoline.

Cutting Techniques

Proper techniques for felling, limbing, and bucking.

Felling: Plan escape path, make notch cut 1/3 of tree diameter, make felling cut leaving hinge.
Limbing: Work from trunk outward, keep saw between you and branch.
Bucking: Support log properly, cut from top down for supported logs.
Kickback prevention: Avoid nose of bar contact, maintain firm grip.
Pinch prevention: Recognize compression and tension wood.

WARNING! Never cut above shoulder height. Always maintain secure footing.

Safety Features

Chain Brake: Stops chain within 0.15 seconds of activation. Throttle Lockout: Must be depressed before throttle works. Right Hand Guard: Protects from chain breakage. Chain Catcher: Catches broken chain. Anti-Vibration: Reduces operator fatigue. Spark Arrestor: Prevents fire hazard.

Care & Maintenance

Daily maintenance: Clean air filter, check chain tension, sharpen chain, clean cooling fins.

Weekly: Clean spark arrestor, check spark plug gap, inspect fuel lines.
