Assembly & Setup

Unpack and inspect contents. Assembly requires attaching guide bar and chain, filling with fuel/oil mix.

Attach guide bar and chain: Place bar over studs, align chain with sprocket, adjust tension.
Fuel mix: Use fresh unleaded gasoline (87 octane min.) with 2-cycle oil at 40:1 ratio (3.2 oz oil per gallon).
Fill oil reservoir: Use bar and chain oil (not motor oil).
Check chain tension: Chain should snap back when pulled from bar; adjust tensioning screw.

CAUTION! Use proper fuel mix to avoid engine damage. Ensure chain is installed with cutting teeth facing forward.

Operation

Starting procedure: Place on flat surface, engage chain brake, set choke, pull starter cord.

Cold start: Set choke to full, press primer bulb 5 times, pull cord until engine fires, move choke to half, pull to start.
Warm start: Choke off, pull cord.
Cutting: Hold saw firmly, keep throttle at full speed during cut, let chain do the work.
Shut off: Release throttle, push stop switch to OFF.

Tip: Allow saw to warm up 30 seconds before cutting. Do not run at idle for extended periods.

Maintenance

Daily: Check chain tension, sharpness; clean air filter; inspect for loose parts.
Weekly: Clean spark arrestor screen; check fuel lines for cracks.
Monthly: Replace spark plug (Champion RCJ-6Y); clean cooling fins.
Storage: Drain fuel or add stabilizer; run dry; store in dry place.

WARNING! Disconnect spark plug wire before performing maintenance.

Chain & Bar Care

Keep chain sharp; file at 30° angle. Rotate bar periodically for even wear.

Sharpening: Use round file matching chain pitch; maintain consistent angle.
Depth gauges: File to proper height (0.025 in.) to prevent kickback.
Bar groove: Clean with bar groove cleaning tool.
Lubrication: Ensure oiler is working; check oil output.

CAUTION! Dull chain increases kickback risk and reduces cutting efficiency.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine won't start	Old fuel, clogged filter, spark plug	Use fresh fuel mix; clean/replace air filter; check spark plug.
Engine runs poorly	Carburetor adjustment, fuel line	Adjust H/L screws per manual; inspect fuel line for leaks.
Chain doesn't turn	Clutch, sprocket, brake engaged	Check clutch springs; replace worn sprocket; disengage chain brake.
Excessive vibration	Loose parts, unbalanced chain	Tighten all bolts/nuts; balance chain by sharpening evenly.
Chain throws oil	Over-oiling, wrong oil type	Adjust oiler screw; use correct bar & chain oil.

Reset: For carburetor, reset to factory settings: H screw 1-1/4 turns out, L screw 1 turn out.
