Stihl 020 AVP Chainsaw (Vintage Specs)
The STIHL 020 AVP is a vintage, roughly 35.2 cm³ chainsaw suited to light and medium limbing and bucking when its parts and safety systems are sound. Confirm the exact model, bar, chain, fuel mix, and service settings before use. A stamped serial number alone should not be treated as proof of age, origin, or authenticity.
Resale value depends less on a seller’s “professional” label than on identity, condition, and whether the saw can be serviced safely. A clean-looking 020 AVP may still need costly work if its chain brake, oiling system, carburetor, or cylinder is damaged. I assess a vintage saw in that order: confirm what it is, check whether it is complete and safe, then judge its price.
A strong purchase is not automatically the saw with the lowest asking price. It is the one whose model and installed parts can be verified, whose faults are understood, and for which you can find competent service support.
What the 020 AVP is and what its specs tell you
The 020 AVP belongs to STIHL’s vintage compact saw family. Its displacement is approximately 35.2 cubic centimetres, or cm³, but the model marking and installed parts matter more than a listing’s claimed specifications. Treat that displacement as a family reference, not proof that every saw has the same setup.
The engine size points to a useful role: limbing and bucking within the saw’s capacity. It is not a substitute for a larger felling saw. “Bucking” means cutting a felled stem into shorter pieces. The saw’s age also makes condition and correct setup central to any performance claim.
| Item | What can be stated safely | What to verify on the saw |
|---|---|---|
| Engine displacement | Approximately 35.2 cm³ for the model family | Confirm the model identification |
| Fuel mix | Use the manual for the saw’s version and oil | Obtain the correct ratio before starting |
| Guide bar and chain | No single setup applies to every configuration | Bar markings, chain pitch and gauge, drive-link count, sprocket |
| Idle and maximum speed | Values depend on applicable STIHL service data | Version-specific settings measured with a tachometer |
| Fastener torque | Do not assume one value fits all fasteners | Correct service data for the part and version |
Key takeaway: A familiar model name does not make a replacement chain, fuel ratio, or carburetor setting universal.
How to identify the saw and assess a used listing
Model identification means checking the markings and construction on the saw rather than trusting a seller’s title. A serial number can help STIHL or a knowledgeable dealer assess a machine, but do not assume that a number’s digits reveal its production year or country of origin.
Ask for clear photos of the model marking and stamped serial number, plus the bar, chain, sprocket area, starter side, and safety controls. Compare the markings with STIHL documentation or ask an authorized dealer to check them. If the number is missing, altered, or hard to read, treat identification as uncertain and price the saw accordingly.
A serial number is not a complete authenticity test. Nor does a genuine engine prove that every fitted part is original or compatible. Look for mismatched components, poor repairs, missing covers, and signs that safety parts have been removed. For a doubtful listing, ask the seller not to start the saw until a qualified person has inspected it.
Illustrative buying cases: If a saw starts but has an unknown bar and chain combination, pause before cutting; check the markings and sprocket match first. If another saw has a readable model mark but no legible serial, ask a dealer whether the remaining details support identification. Neither example confirms a particular saw’s history.
Key takeaway: Treat uncertain identity as a resale and repair risk, not as a small paperwork issue.
Equipment Setup and Safety Preparation
Setup is the check that confirms the saw, its cutting parts, and the work area are ready before starting. On a vintage machine, inspect the safety controls and installed parts rather than assuming they remain correct. If a critical fault appears, do not run the saw until it is repaired and checked.
Use chainsaw-rated leg protection, a helmet with face and eye protection, hearing protection, gloves, and suitable boots. Inspect the chain brake, throttle lockout, chain catcher, handles, bar, chain tension, and fasteners. Identify the intended cut, escape paths, overhead hazards, and bystanders. Follow applicable ANSI Z133 and OSHA requirements.
Match the chain to the guide bar’s stamped pitch and gauge. “Pitch” is the spacing used to describe chain size; “gauge” is the thickness of the chain drive links that fit the bar groove. Confirm drive-link count and sprocket compatibility for the exact parts. If markings are absent or unclear, ask a qualified dealer to identify the setup.
Use the fuel ratio specified in the manual for the saw’s production version and the oil being used. Do not assume a newer STIHL ratio applies. If you cannot confirm the correct specification, get guidance from STIHL or an authorized dealer before running the engine. Incorrect lubrication can cause severe engine damage.
Key takeaway: Do not start until the fuel specification, cutting setup, and safety parts are verified.
Field Cutting and Landscaping Operation
Operation means starting, cutting, and stopping the saw with control while keeping people clear of the work area. The 020 AVP’s compact engine is for light-to-medium limbing and bucking within the operator’s skill and the saw’s capacity, not for every tree or cut.
Follow the manual’s cold- or warm-start procedure on stable ground, with the chain brake engaged. Never drop-start the saw. After starting, check for fuel or oil leaks and confirm chain lubrication before cutting. If lubrication is not evident or a leak appears, stop and investigate rather than continuing.
Keep two hands on the saw and hold a stable stance. Cut below shoulder height, avoid the guide-bar nose, and keep bystanders away. Upper-quadrant kickback occurs when the upper part of the bar nose contacts wood or another object; the saw can rotate violently toward the operator. Keep the nose clear. The chain brake is not a substitute for safe technique.
Do not force a dull, damaged, or mismatched chain through wood. Stop and correct the chain or bar compatibility first. Leave tree felling to a competent, properly equipped operator. This is especially important with an old saw whose condition or service history is not known.
Key takeaway: Use this saw only for work within both its verified condition and your training.
Maintenance, Sharpening, and Carburetor Tuning
Maintenance keeps the saw safe and helps reveal faults before they grow. On this model, use service information that matches the saw’s version and installed parts. Do not guess maximum speed, idle speed, or fastener torque; incorrect settings can damage the engine or make the saw unsafe.
Switch off, let the engine and exhaust cool, and disconnect the spark-plug lead before maintenance. Clean the air intake, bar groove, and oil passages. Check chain tension, cutters, depth gauges, and brake function. A “depth gauge,” sometimes called a raker, controls how deeply a cutter bites into the wood.
Sharpen to the chain maker’s specifications with the correct file and gauge tools. Set depth gauges to that same chain specification; do not apply a generic clearance to an unidentified chain. Replace damaged parts instead of trying to sharpen or adjust away a fault.
Carburetor work requires the correct service data and a tachometer, an instrument that measures engine speed. Have a qualified technician confirm the model version and settings before adjustment. If the saw races, stalls, leaks, or runs poorly, diagnosis should come before continued cutting.
Key takeaway: Correct model-specific data matters more than a remembered setting from another STIHL saw.
Storage and Seasonal Care
Storage means preparing the saw so fuel, dirt, and moisture do not create avoidable problems while it sits unused. Follow the manual for fuel handling and storage, and keep the saw away from ignition sources. Do not leave a questionable fuel mix in the machine based on guesswork.
After use, switch off the saw and let the engine and exhaust cool. Clean the saw, bar groove, and oil passages, then inspect the chain and brake. Store it securely, out of children’s reach, with the bar and chain protected. Before the next use, repeat the safety and setup checks.
Key takeaway: A stored saw still needs a fresh inspection before it returns to service.
Resale value and a practical purchase decision
Resale value reflects more than cosmetic condition. A buyer can judge a saw more confidently when its identity is clear, its safety systems work, its parts match, and its maintenance needs are disclosed. A polished finish cannot confirm any of those points.
Before agreeing on a price, ask whether the saw can be inspected cold, request photos of markings and components, and confirm what work has been done. If the seller cannot establish the fuel specification or cutting-part compatibility, include the cost of professional identification and service in your decision. Avoid paying extra for “pro” wording without evidence of condition and parts.
Key takeaway: Buy the verifiable saw, not the most confident description.
Frequently asked questions
These answers focus on identification, safe setup, and the common specification questions buyers raise about the vintage 020 AVP. When documentation and installed parts disagree, identify the exact saw and components before relying on a general model-family figure.
What is the displacement of the 020 AVP?
The model family is approximately 35.2 cm³. Confirm the model marking on the saw before using that figure in a listing or repair decision. Displacement alone does not establish the saw’s condition, output, year, or correct replacement parts.
What fuel mix should I use?
Use the ratio specified in the manual for that saw’s production version and oil. Do not assume 50:1 or copy a newer model’s guidance. If you cannot establish the correct specification, ask STIHL or an authorized dealer before starting the saw.
What bar and chain fit an 020 AVP?
There is no single bar and chain combination that can safely be prescribed for every saw. Match chain pitch and gauge to the bar markings, then confirm drive-link count and sprocket compatibility. Ask a dealer to identify parts if markings are unclear.
Can I identify its year from the serial number?
Do not infer the production year from a few digits without a reliable STIHL source. Record the model and serial markings, then ask STIHL or an authorized dealer to check them. A serial number by itself does not prove authenticity or original configuration.
Is the 020 AVP suitable for tree felling?
It should not be treated as a general-purpose felling saw. Its roughly 35.2 cm³ engine suits light-to-medium limbing and bucking when the saw is serviceable and correctly configured. Leave tree felling to a competent operator with suitable equipment and training.
What should I inspect before buying one used?
Check identity markings, safety controls, handles, bar, chain, sprocket area, leaks, and visible damage. Ask for a cold inspection and service history. If the serial is missing, parts are mismatched, or a safety feature fails, treat that as a significant risk.
How should I sharpen its chain?
Identify the chain and follow its manufacturer’s filing and depth-gauge specifications. Use the correct file and gauge tools. Do not apply a generic raker clearance to an unknown chain, and do not cut with dull, damaged, or mismatched parts.
What RPM should the carburetor be set to?
Use serial- and version-specific STIHL service data and a tachometer. Do not guess an idle or maximum speed based on another model or an online claim. If the correct data is unavailable, have a qualified STIHL service provider identify the saw before tuning.
