Features at a Glance

Key components: 53.2cc professional engine, 20-inch guide bar, automatic chain oiler, decompression valve, anti-vibration system, adjustable automatic chain brake.

Assembly Instructions

Unpack and inspect all components. Ensure all parts are present before assembly.

1. Attach guide bar: Remove bar cover nuts, position bar on studs, align chain sprocket.
2. Install chain: Place chain over bar with cutting teeth facing forward, engage drive links.
3. Adjust chain tension: Tighten bar nuts hand-tight, adjust tension screw until chain snaps back.
4. Final tension: Tighten bar nuts to specification (28-32 ft-lbs).
5. Fill tanks: Add proper fuel/oil mixture to fuel tank, bar and chain oil to oil tank.

WARNING! Always wear protective gloves when handling chain. Ensure chain is properly tensioned before operation.

First-Time Operation

Complete assembly and perform pre-operation checks before starting.

1. Safety check: Verify chain brake functions, chain tension, all fasteners tight.
2. Fuel mixture: Use 50:1 gasoline to 2-cycle oil mixture (89 octane minimum).
3. Starting procedure: Set choke, pull starter rope until engine fires, move choke to run position.
4. Warm-up: Allow engine to warm for 30 seconds before cutting.
5. Test chain brake: Engage brake at idle to verify operation.

CAUTION! Never start chainsaw without proper bar and chain installation. Keep bystanders at least 15 feet away.

Control Locations: Throttle trigger (right handle), Chain brake lever (front guard), Choke lever (left side), Decompression valve (cylinder head), Master control lever (combines choke/stop functions).

Adjustments: Chain tension (side cover), Idle speed (carburetor screw), Oil flow rate (adjustment screw near oil tank). Settings: Chain brake sensitivity (adjustment screw on brake mechanism), Anti-vibration system (pre-set at factory).

Fuel and Oil Requirements

Fuel: 50:1 mixture of unleaded gasoline (89 octane minimum) and Echo 2-stroke oil. Bar Oil: Use Echo bar and chain oil or equivalent SAE 30 weight.

1. Mix fuel in separate container before adding to saw.
2. Fill fuel tank to 80% capacity to allow for expansion.
3. Check oil flow by running saw over light-colored surface.
4. Adjust oil flow for cutting conditions (more for hardwoods, less for softwoods).

Tip: Always use fresh fuel (less than 30 days old). Store fuel in approved containers.

Cutting Techniques

Proper techniques ensure safety and efficiency.

1. Felling: Use notch and back cut method. Plan escape path before cutting.
2. Limbing: Work from trunk outward. Keep saw between you and branch.
3. Bucking: Support logs properly. Cut from top down for supported logs.
4. Kickback prevention: Maintain firm grip, avoid upper quadrant of bar tip.
5. Pushing/pulling: Let saw cut at its own pace; don't force through material.
6. Pinch prevention: Use wedges when cutting compressed wood.
7. Overhead cutting: Avoid whenever possible. Wear helmet if necessary.
8. Cutting angle: Hold saw at slight angle to reduce kickback risk.

WARNING! Always cut at full throttle. Never cut with bar tip. Watch for binding.

Safety Features

Chain Brake: Automatically engages during kickback or manually activated. Throttle Lockout: Prevents accidental throttle engagement. Right Hand Guard: Protects from broken chain. Anti-Vibration: Reduces operator fatigue. Decompression Valve: Reduces pulling effort by 40%.

Care & Maintenance

Daily maintenance ensures optimal performance and safety.

1. Clean air filter: Remove and clean with compressed air or soapy water.
2. Check chain tension: Adjust when chain sags from bar rails.
3. Sharpen chain: Use round file matching chain pitch (5/32" for .325 chain).
4. Clean cooling fins: Remove debris from cylinder fins.
5. Check spark plug: Clean and gap to .025 inches.
6. Clean guide bar: Remove burrs from bar rails, rotate bar regularly.
7. Lubricate sprocket: Grease sprocket bearing weekly.

CAUTION! Disconnect spark plug before performing maintenance. Allow engine to cool completely.
