Operation Guide

Starting, cutting techniques, and stopping procedure.

Starting (Cold): Engage chain brake. Set master control to choke. Pull starter rope until engine 'pops'. Move control to run position. Pull again to start.
Starting (Warm): Set control to run position (no choke). Pull starter rope.
Cutting: Use full throttle in the cut. Let chain do the work; do not force. Be aware of pinch points and kickback.
Stopping: Release throttle, allow to idle briefly, press stop switch to '0'.

Tip: Maintain sharp chain for efficient cutting and reduced operator strain.

Maintenance Schedule

Regular maintenance ensures performance and longevity.

Interval	Task
Before each use	Check chain tension, sharpness, and lubrication. Inspect for loose parts.
Every 5 hours	Clean air filter. Check spark plug condition.
Every 20 hours	Clean spark arrestor screen (if equipped). Clean cooling fins.
Every 50 hours	Replace fuel filter. Clean carburetor air intake.
Annually	Check all nuts/bolts for tightness. Have professional check ignition and carburetor settings.

WARNING! Perform maintenance only when saw is cool and spark plug wire is disconnected.

Chain & Bar Care

Proper care of cutting attachments is critical.

Sharpening: Use correct round file size. Maintain correct filing angle (typically 30°). File all cutters evenly.
Tensioning: Chain should be snug against bar but pull freely by hand. Re-tension when chain is warm after initial use.
Bar Maintenance: Clean bar groove regularly. Flip bar periodically for even wear. Dress bar rails if burred.
Lubrication: Always use recommended bar and chain oil. Check oil flow before cutting.

Storage Guidelines

Prepare saw for short or long-term storage.

For storage over 30 days: 1. Empty fuel tank and run carburetor dry. 2. Remove chain, clean, and soak in oil. 3. Clean entire saw. 4. Store in a dry, dust-free place.

CAUTION! Never store saw with fuel in the tank for long periods. Old fuel can damage carburetor components.
