Operating Instructions

Proper operating procedures for safe and efficient use.

1. Pre-start check: Verify all fasteners are tight, chain is properly tensioned, and no damage is present.
2. Starting procedure: Engage chain brake, set master control to cold start position, pull starter rope until resistance is felt, then pull briskly.
3. Warm-up: Allow engine to warm up at idle for 30-60 seconds.
4. Cutting techniques: Use proper stance, maintain secure grip, avoid kickback zones, plan escape path.
5. Shutdown: Allow engine to idle for 30 seconds, engage chain brake, move stop switch to OFF position.

Tip: Always cut at full throttle for best performance and reduced chain wear.

Maintenance Procedures

Regular maintenance schedule and procedures.

1. Daily: Clean air filter, check chain tension and sharpness, inspect for damage.
2. Weekly: Clean cooling fins, check spark plug condition, clean exterior.
3. Monthly: Clean fuel filter, check fuel lines, inspect anti-vibration elements.
4. Seasonal: Replace spark plug, clean carburetor (by technician), check clutch.
5. Chain maintenance: Regular sharpening, proper depth gauge setting, lubrication check.
6. Bar maintenance: Clean bar groove, rotate bar regularly, check for wear.

WARNING! Disconnect spark plug wire before performing maintenance. Use only STIHL-approved replacement parts.

Storage Guidelines

Proper storage procedures for equipment not in use.

Short-term storage (less than 30 days): Drain fuel from carburetor, run engine until it stops, clean equipment, store in dry location.

Long-term storage (more than 30 days): Drain all fuel from tank, run engine until it stops, remove spark plug and add teaspoon of oil to cylinder, pull starter rope slowly to distribute oil, reinstall spark plug, clean thoroughly, store in dry, protected area.

CAUTION! Never store equipment with fuel in tank for extended periods. Fuel deterioration can damage engine components.

Troubleshooting

Problem	Possible Cause	Solution
Engine won't start	No fuel, flooded engine, bad spark plug, clogged air filter	Check fuel, wait 10 minutes if flooded, replace spark plug, clean air filter
Engine runs poorly	Dirty air filter, old fuel, clogged fuel filter, carburetor issues	Clean/replace air filter, use fresh fuel, replace fuel filter, have carburetor serviced
Chain doesn't turn	Chain brake engaged, clutch worn, drive sprocket worn	Disengage chain brake, replace clutch, replace drive sprocket
Excessive vibration	Loose components, unbalanced chain, worn anti-vibration elements	Tighten all fasteners, balance chain, replace anti-vibration elements
Chain doesn't oil	Empty oil tank, clogged oil passage, worn oil pump	Fill oil tank, clean oil passages, replace oil pump
Overheating	Dirty cooling fins, dull chain, improper fuel mixture	Clean cooling fins, sharpen chain, use proper fuel/oil ratio
Exhaust smoke	Rich fuel mixture, worn piston/cylinder	Adjust carburetor (technician), inspect engine components
