Chain Brake Lever: Manual activation; also inertia-activated. Decompression Valve: Button to reduce compression for easier starting. Chain Tensioner: Screw for adjusting chain slack. Fuel/Oil Caps: For refilling.

Operation: Set Master Control to choke for cold start, run for operation, stop to shut off. Engage throttle lockout before pulling trigger.

Starting & Stopping Procedures

Starting (Cold): Place on firm ground. Engage chain brake. Set Master Control to choke. Press decompression valve. Pull starter cord until engine fires. Move Master Control to run. Pull cord to start. Starting (Warm): Set Master Control to run, pull cord.

1. Ensure chain brake is engaged before starting.
2. Hold front handle with left hand, place right foot in rear handle.
3. Pull starter cord briskly; do not yank.
4. After starting, disengage chain brake by pulling front handguard toward you.
5. To stop: Release throttle, set Master Control to STOP.

Tip: If engine floods, set Master Control to run and pull starter cord repeatedly with throttle open.

Operation & Cutting Techniques

Basic cuts: felling, limbing, bucking.

1. Felling: Plan escape path. Make notch cut on fall side, then back cut. Use wedges if needed.
2. Limbing: Stand on opposite side of log. Cut branches from bottom to top.
3. Bucking: Support log. Cut from top down; avoid cutting into ground.
4. Use full throttle during cuts; let chain do the work.
5. Be aware of kickback zone (upper quadrant of bar tip).

WARNING! Kickback can occur instantly. Always grip handles firmly and maintain balance. Never cut with bar tip.

Maintenance Schedule

Daily: Clean air filter, check chain tension and sharpness, inspect bar for wear. Weekly: Clean spark arrestor screen, check fuel filter. Monthly: Clean cooling fins, check spark plug, replace fuel filter if clogged. As needed: Sharpen chain, replace bar, clean clutch drum.

CAUTION! Disconnect spark plug wire before performing maintenance. Use only STIHL replacement parts.

Chain & Bar Care

Sharpen chain regularly with round file and guide. Maintain proper depth gauge settings. Rotate bar periodically to ensure even wear. Clean bar groove and oil holes. Ensure oiler port is clear.

Tip: A sharp chain reduces effort and prevents kickback. File cutters at 30° angle.

Storage Guidelines

Long-term storage: Drain fuel tank and run engine until it stops. Remove spark plug, add a few drops of oil to cylinder, pull starter cord slowly, reinstall plug. Clean entire saw. Store in dry place, cover bar and chain with oil.

CAUTION! Never store with fuel in tank for more than 30 days; fuel degrades and can damage engine.

Troubleshooting
