Safety Information

Read all instructions before operation. Wear proper protective equipment.

Personal Protective Equipment: Wear safety glasses, hearing protection, gloves, chainsaw chaps, and steel-toed boots.
Work Area Safety: Clear area of bystanders, especially children. Ensure secure footing.
Kickback Prevention: Hold saw firmly with both hands. Do not cut with tip of bar.
Fuel Safety: Refuel outdoors, away from ignition sources. Use fresh fuel mix.

WARNING! Chainsaw kickback can cause serious injury or death. Always maintain proper grip and stance.

Assembly & Preparation

Unpack and inspect contents. Assemble guide bar and chain.

Attach guide bar: Place bar on studs, align chain, tighten nuts finger-tight.
Install chain: Ensure cutting teeth face forward on top of bar.
Tension chain: Use side adjuster until chain snaps back when pulled from bar.
Final tightening: Tighten bar nuts securely after proper tension is set.
Fill tanks: Add fuel mix (50:1 gasoline to 2-stroke oil) and chain oil.

CAUTION! Chain must move freely when pulled. Overtightening can damage bar and chain.

Starting the Chainsaw

Cold start procedure (for engine at ambient temperature):

Place saw on flat ground, clear of debris.
Activate chain brake by pushing front hand guard forward.
Press decompression valve (if equipped).
Set choke control to full choke position.
Press throttle trigger lockout and pull starter cord 3-4 times until engine fires.
Move choke to half-throttle position.
Pull starter cord until engine starts.
Blip throttle to disengage fast idle, release chain brake.

Warm Start: Do not use choke. Follow steps 1-2, then pull starter cord.

Operating Instructions

Basic cutting techniques for felling, limbing, and bucking.

Felling: Plan escape path. Make notch cut (1/3 tree diameter), then felling cut.
Limbing: Stand on left side of trunk. Work from base to top.
Bucking: Support log properly. Cut from top side when possible.
Kickback Zone: Avoid contact with upper quadrant of bar tip.
Chain Brake Test: Verify function before each use by pulling guard forward.

Tip: Let chain do the work; don't force the saw. Maintain sharp chain.

Maintenance Schedule

Interval	Task
Daily	Check chain tension, sharpness, and lubrication
Daily	Clean air filter (more often in dusty conditions)
Weekly	Clean cooling fins and spark arrestor screen
Monthly	Check spark plug condition and gap (0.020")
Seasonally	Replace fuel filter and inspect fuel lines
Annually	Professional inspection of piston, cylinder, bearings

CAUTION! Always disconnect spark plug before performing maintenance.

Chain Sharpening & Tensioning

Proper chain maintenance ensures optimal performance and safety.

Sharpening: Use round file matching chain pitch. Maintain 30° cutting angle.
Depth Gauges: File down to 0.025" below cutter edge using depth gauge tool.
Tensioning: Chain should snap back when pulled from middle of bar.
Adjustment: Loosen bar nuts, turn tensioning screw clockwise, retighten nuts.
Lubrication: Check oil flow by running saw near light surface; look for oil line.

WARNING! Never operate with dull or loose chain. Increases kickback risk.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

Empty fuel tank or add fuel stabilizer.
Run engine until carburetor is dry.
Remove chain, clean, and soak in oil.
Clean entire saw, especially cooling fins.
Store in dry place, protected from moisture.

Long-term: Remove spark plug, add teaspoon of oil to cylinder, pull starter cord slowly to distribute.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine won't start	No spark, flooded, stale fuel	Check spark plug; wait if flooded; use fresh fuel mix.
Engine runs then dies	Clogged fuel filter, air leak	Replace fuel filter; check fuel lines and carburetor seals.
Poor cutting performance	Dull chain, improper tension	Sharpen chain; adjust tension; check bar groove.
Chain won't oil	Empty oil tank, clogged ports	Fill tank; clean oil holes in bar; check pump function.
Excessive vibration	Loose components, unbalanced chain	Tighten all fasteners; check chain for damaged cutters.
Chain brake not engaging	Worn brake band, dirty mechanism	Clean brake components; replace brake band if worn.
