Chain breaker and spinner (for chain repair).
File and filing guide for chain sharpening.
Compression gauge and tachometer (for advanced tuning).

WARNING! Use the correct tool for the job to avoid damage to components or personal injury.

Routine Maintenance

Regular maintenance ensures optimal performance and longevity.

Daily/Pre-Use: Check chain tension, bar oil level, and fuel level. Inspect for loose parts.
Weekly/Monthly: Clean air filter, check spark plug condition, clean cooling fins.
Seasonal: Sharpen chain, inspect/replace drive sprocket, clean fuel filter, replace bar oil.
Storage: Drain fuel or add stabilizer. Store in a dry place.

CAUTION! Allow engine to cool completely before performing maintenance.

Engine Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine won't start	No spark, flooded, fuel issue	Check spark plug, air filter, fuel lines, and carburetor.
Engine starts then dies	Clogged fuel filter, carb adjustment	Clean/replace fuel filter; adjust carburetor low-speed screw.
Loss of power	Dirty air filter, fouled plug, exhaust port clogged	Clean air filter, replace spark plug, decarbonize exhaust.
Excessive vibration	Loose components, unbalanced chain	Tighten all bolts/nuts; check chain for damage and balance.
Overheating	Dirty cooling fins, lean fuel mix	Clean cooling fins; ensure proper fuel/oil mix ratio.

Chain & Bar Maintenance

Proper chain and bar care is critical for safe and efficient cutting.

Tensioning: Chain should be snug against the bar but pull freely by hand. Adjust tensioning screw.
Sharpening: Use correct file size. Maintain cutting angle (typically 30°-35°). File all cutters evenly.
Bar Care: Flip bar regularly to ensure even wear. Clean bar groove and oil holes.
Lubrication: Always use proper bar and chain oil. Check oiler port for clogs.

WARNING! A dull or loose chain is dangerous and increases kickback risk.

Carburetor Adjustment

Standard adjustment procedure for Walbro or Zama carburetors. Engine must be at operating temperature.

Locate adjustment screws: L (Low speed), H (High speed), and sometimes T (Idle).
Initial setting: Gently turn L and H screws clockwise until seated, then back out 1.5 turns.
Start engine. Adjust L screw for smoothest idle. Adjust H screw for maximum RPM (use tachometer if possible).
Fine-tune idle speed with T screw if present. Chain should not move at idle.

Tip: Record initial screw positions before adjustment.

Ignition System

Testing and replacing ignition components.

Spark Plug: Check gap (typically .025"). Replace if electrode is worn or fouled.
Ignition Coil: Test with multimeter for proper resistance (refer to service manual for values).
Stop Switch: Ensure wire is not grounded or damaged, preventing spark.
Flywheel & Magneto: Check for damage or debris. Air gap should be consistent.

CAUTION! Always disconnect spark plug wire before testing ignition components.

Fuel System

Maintaining a clean fuel system is essential.

Fuel Tank: Inspect for cracks or leaks. Clean interior if contaminated.
Fuel Lines: Replace if cracked, brittle, or leaking. Ensure proper routing.
Fuel Filter: Replace annually or if clogged. Located inside fuel tank.
Carburetor Diaphragm & Gaskets: Inspect for tears or stiffness. Replace kit if needed.

WARNING! Use only fresh, properly mixed fuel. Stale fuel is a common cause of starting issues.
