1. Engine: Two-stroke, single-cylinder gasoline engine.
2. Anti-Vibration System (AV): Rubber dampeners isolate handles from engine and cutting assembly.
3. Chain Brake: Inertia-activated front hand guard to stop chain in kickback events.
4. Decompression Valve: Eases starting by reducing cylinder pressure.
5. Chain Oiler: Automatic and manual oiling system for bar and chain lubrication.
6. Throttle Interlock: Prevents accidental throttle activation.
7. Master Control Lever: Combines stop switch, choke, and start functions.
8. Side-Access Chain Tensioner: Allows easy chain adjustment without tools.

Assembly & Initial Setup

Assembling your STIHL 024 AV for first-time use.

1. Attach Guide Bar & Chain: Place bar on studs, fit chain with cutters facing forward in top bar groove. Adjust tension.
2. Fill Fuel Tank: Use fresh, high-quality gasoline mixed with STIHL 2-stroke oil at 50:1 ratio (unless otherwise specified).
3. Fill Chain Oil Tank: Use STIHL chain oil or approved equivalent.
4. Check Controls: Ensure throttle trigger, throttle interlock, and chain brake function correctly.
5. Start the Engine: Place saw on firm ground, engage chain brake, set master control to cold start position, pull starter cord firmly.

CAUTION! Always wear protective gear during assembly and starting. Ensure chain brake is engaged before starting.

Controls & Operation

Understanding and using the chainsaw controls.

Master Control Lever: Positions: STOP (0), RUN (I), COLD START (Choke Symbol), WARM START (Half Choke).

Throttle Trigger & Interlock: Press interlock with palm while pulling trigger to engage throttle.

Chain Brake/Front Hand Guard: Push forward to engage brake; pull back towards handle to disengage.

Chain Oiler Control: Manual oiler button (if equipped) for extra lubrication.

Starting Procedure: Engage chain brake. Set master control to cold start. Hold saw firmly on ground. Pull starter cord until engine fires. Move control to warm start, pull again to start. Disengage chain brake before cutting.

Fuel & Lubrication

Proper fuel mix and lubrication are critical for performance and engine life.

1. Fuel: Use unleaded gasoline with minimum 89 octane. Mix with STIHL 2-Stroke Oil at 50:1 ratio. Shake container well. Do not use fuel older than 30 days.
2. Chain Oil: Use STIHL chain oil or a high-quality, tacky bar & chain oil. Check oil level before each use.
3. Refueling: Stop engine and allow to cool. Clean area around caps. Refill both tanks. Tighten caps securely. Wipe away any spills.

WARNING! Fuel is highly flammable. No smoking. Refuel outdoors away from ignition sources.

Chain & Bar Maintenance

Regular maintenance ensures safe and efficient cutting.

1. Chain Sharpening: Use correct round file size. Maintain correct filing angle (typically 30°). File all cutters to equal length.
2. Chain Tension: Adjust when chain sags from bottom of bar. Chain should snap back when pulled from bar. Adjust with side tensioner when saw is cool.
3. Bar Maintenance: Regularly clean bar groove and oil holes. Flip bar weekly for even wear.
4. Depth Gauges: File down depth gauges (rakers) with a flat file and gauge tool to maintain proper height relative to cutters.

CAUTION! Always wear heavy gloves when handling the chain. Ensure engine is off and spark plug wire is disconnected.

Engine Maintenance

Routine engine care for long service life.

• Air Filter: Clean regularly (tap out debris) or replace when dirty. A clogged filter reduces power.
• Spark Plug: Check and clean electrode gap (0.020" / 0.5 mm). Replace if worn or fouled.
• Spark Arrestor Screen (Muffler): Clean carbon deposits periodically to prevent overheating.
• Cylinder Fins: Keep cooling fins clean for proper engine cooling.
• Fuel Filter: Replace annually or if fuel flow is restricted.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Long-Term Storage: Run engine dry of fuel or add fuel stabilizer. Run engine for 2 minutes to circulate treated fuel.
2. Clean Saw: Remove all dirt, sawdust, and resin.
3. Chain & Bar: Remove, clean, and coat with oil. Store loosely.
4. Location: Store in a dry, secure place, out of reach of children.

CAUTION! Never store saw with fuel in tank in an enclosed area or near open flames or sparks.
