Welcome to the central resource for STIHL chainsaw user manuals, safety instructions, maintenance guides, and troubleshooting information. STIHL is a leading manufacturer of professional-grade and consumer chainsaws, known for their durability, performance, and safety features. Below are key sections covering safety, operation, maintenance, specifications, and support for various STIHL chainsaw models.
Operating a chainsaw is inherently dangerous. Always read and understand the manual before use.
| Hazard | Precaution |
|---|---|
| Kickback | Always use a low-kickback chain, hold saw firmly with both hands, and avoid contact with the upper tip of the bar. |
| Hearing Damage | Wear approved hearing protection at all times during operation. |
| Eye Injury | Always wear safety glasses or a face shield. |
| Breathing Hazards | Operate in well-ventilated areas; avoid inhaling exhaust fumes. |
| Cutting Hazards | Ensure the chain is stopped when not actively cutting. Use proper chain brake. |
| Fuel Safety | Refuel in a well-ventilated area with the engine off and cool. Use only STIHL-approved fuel mix. |
| Electrical Hazards (Electric Models) | Use a GFCI-protected outlet. Keep cord away from cutting area. |
| Maintenance Safety | Disconnect spark plug (gas) or power cord (electric) before performing any maintenance. |
STIHL offers a range of chainsaws from lightweight homeowner models to professional arborist tools.
WARNING! Always select a saw appropriate for your experience level and the task. Using an overpowered saw increases risk.
Most STIHL chainsaws require minor assembly before first use.
CAUTION! Do not attempt to start the saw until assembly is complete and you have read the safety section.
Proper starting and cutting technique is essential for safety and performance.
Starting (Gas Model): Place on firm ground. Engage chain brake. Set master control lever to cold start/choke position. Pull starter rope sharply until engine fires. Disengage choke. Pull again to start. Disengage chain brake before cutting.
Starting (Electric/Battery): Connect to power or insert battery. Engage safety trigger and squeeze the main trigger.
Basic Cutting: 1. Use a firm, two-handed grip. 2. Let the saw do the work; don't force it. 3. Cut at full throttle. 4. Be aware of pinch points, especially when cutting logs under tension. 5. Use the bumper spike for leverage when making felling cuts.
Stopping: Release the throttle trigger. For gas models, move the master control lever to the STOP position.
Regular maintenance ensures longevity and safe operation.
Tip: A sharp chain is safer and more efficient than a dull one. Sharpen often.
Using the correct fluids is critical for engine life and chain performance.
WARNING! Never use automotive motor oil in the fuel mix. Never use fuel older than 60 days. Store fuel in an approved container away from heat and sparks.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Engine won't start | Old fuel, flooded engine, clogged filter, spark plug | Use fresh fuel mix. Wait if flooded. Clean/replace air & fuel filters. Check/replace spark plug. |
| Engine starts then dies | Clogged fuel filter, carburetor issues, vent hole blocked | Replace fuel filter. Clean carburetor screen. Ensure fuel tank cap vent is clear. |
| Chain doesn't turn or turns slowly | Chain brake engaged, low chain oil, worn sprocket, clutch issues | Disengage brake. Check oiler and fill. Inspect drive sprocket and clutch. |
| Excessive vibration | Loose parts, unbalanced/damaged chain, damaged bar | Tighten all nuts/bolts. Sharpen chain evenly. Inspect bar for wear/damage. |
| Chain throws oil but doesn't cut well | Dull chain, depth gauges too high | Sharpen chain. File down depth gauges (rakers) to proper height. |
| Battery saw lacks power/runtime | Old/bad battery, cold temperature, dirty air filter | Charge battery fully. Use in moderate temps. Clean air filter. |
Reset: For electronic ignition issues, disconnect spark plug wire for 1 minute to reset module.

| Question | Answer |
|---|---|
| What is the fuel/oil mix ratio for my STIHL saw? | Most modern saws use a 50:1 ratio (2.6 oz oil per gallon of gas). Check your manual's specification page. Always use high-quality 2-cycle oil. |
| How often should I sharpen the chain? | Sharpen whenever you have to push the saw through the wood, it produces fine dust instead of chips, or it cuts crooked. It's better to sharpen little and often. |
| Can I use regular motor oil for the chain oil? | No. Use proper bar and chain oil. It's tackier and adheres to the chain better. Motor oil can damage the oiler system and is less effective. |
| My saw has no spark. What should I do? | Check the spark plug first. If it's good, the ignition module may be faulty. This is a repair for an authorized dealer. |
| How do I store my chainsaw for winter? | 1. Run the saw dry of fuel or add fuel stabilizer. 2. Clean the entire saw. 3. Remove and clean the chain/bar. 4. Store in a dry, secure place. |
| Where is the model number on my STIHL saw? | It is stamped on the housing, typically on the right-hand side near the rear or on the crankcase. |
