Fuel & Oil

Use fresh unleaded gasoline (max 10% ethanol) mixed with high-quality 2-cycle engine oil at 40:1 ratio. Use dedicated bar and chain oil in oil tank.

Mix fuel in approved container; shake well.
Fill fuel tank on level surface; wipe spills.
Check oil level before each use; adjust oiler screw for cutting conditions (more for hardwoods).

WARNING! No gasoline substitutes (e.g., E85, diesel). Store fuel in cool, dry place.

Starting & Operation

Starting procedure:

Place saw on clear ground; engage chain brake.
Switch ON; set choke to full (cold) or half (warm).
Press primer bulb 5-6 times.
Pull starter rope briskly until engine fires.
Move choke to half; pull until engine runs.
Disengage chain brake; squeeze throttle to idle.

Cutting: Use lower part of bar; let saw do the work; avoid pinching. For felling, plan escape path.

Maintenance

Daily: Check chain tension, sharpness, oil level. Clean air filter, cooling fins, and bar groove. Weekly: Inspect spark plug, fuel filter, bar for wear. Replace as needed.

Spark Plug: Champion RCJ-6Y or equivalent; gap 0.025". Air Filter: Clean with soapy water; dry completely.

Chain Sharpening

Use round file (5/32") and file guide. Maintain 30° cutting angle, 10° top plate angle. File each cutter equally; check depth gauges with gauge tool.

Secure bar; mark starting cutter.
File from inside out; maintain angle.
File depth gauges to 0.025" below cutter.

Tip: Sharpen frequently; dull chain causes poor cutting and wear.

Storage

Long-term storage: Drain fuel tank and run engine dry. Remove chain, clean and oil bar and chain. Store in dry place, cover saw.

CAUTION! Never store with fuel in tank for more than 30 days; fuel degrades and damages carburetor.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine won't start	No spark/fuel/flooded	Check spark plug; fresh fuel; dry plug (flooded).
Engine runs poorly	Dirty air filter/clogged fuel filter	Clean/replace air filter; replace fuel filter.
Chain won't oil	Empty oil tank/clogged oiler	Fill tank; clean oil ports; check oiler screw.
Chain comes off bar	Loose bar nuts/worn bar	Tighten nuts; inspect bar for wear; replace if grooved.
Excessive vibration	Loose components/damaged AV mounts	Tighten all fasteners; inspect anti-vibration mounts.
