Husqvarna 570 Chainsaw (Specs & Features)
The Husqvarna 570 is a 70.7 cm³ professional-class gasoline chainsaw rated at 3.6 kW, or about 4.8 hp, at 9,600 rpm. Its chain speed at maximum power is 20.7 m/s. Bar and chain fit depend on the saw’s exact version, so check its manual and bar markings before buying parts or putting it to work.
What the Husqvarna 570 is
The 570 is a high-power saw intended for demanding cutting, not a light homeowner model. Its displacement and output can suit ground-based forestry and tree work, but they also mean more weight, noise, vibration, and risk than a small homeowner saw. Choose it for the work you do, not just its power rating.
I compare the 570 by its powerhead, service condition, and support options, rather than by a seller’s “professional” label. On a used saw, a worn clutch, damaged bar, or neglected air filter can matter more than the model name. Ease of care is reasonable when routine cleaning and checks are kept up, but this is still a two-stroke machine that needs correct fuel, sharp chain, and regular inspection.
Husqvarna 570 specifications
These are the core figures for the model information in this guide. They describe engine and chain performance, not every part of every market version. A used saw’s manual, type plate, and fitted equipment should guide decisions about fuel, replacement parts, and service.
| Specification | Figure |
|---|---|
| Engine displacement | 70.7 cm³ |
| Maximum output | 3.6 kW, about 4.8 hp |
| Engine speed at maximum output | 9,600 rpm |
| Idle speed | 2,700 rpm |
| Chain speed at maximum engine power | 20.7 m/s |
| Fuel mix with Husqvarna two-stroke oil | 50:1 gasoline to oil |
| Common chain pitch | 3/8 in; confirm the exact setup |
Displacement is the volume swept by the engine’s piston. It helps describe engine size, but it does not tell you whether a particular bar and chain fit. Bar mount, pitch, gauge, and drive-link count must all match the saw and each other.
The listed power and speed figures are useful for identifying the saw’s intended class. They do not promise a set cutting rate. Chain sharpness, wood condition, bar length, and maintenance all affect work in the field.
Bar, chain, and setup compatibility
Bar-and-chain compatibility means that the bar mount and chain dimensions match the saw’s hardware. Do not select a setup by engine size alone. Use a combination approved for the exact 570 version and market, and check its operator’s manual before installing a bar or chain.
The 570 is commonly configured for 3/8-inch pitch chain, but pitch is only one of three key dimensions. Gauge is the thickness of the chain drive links; drive-link count is the number of links that fit around a specific bar. Read the bar markings and match them to the chain and manual.
| Check | What to confirm | Why it matters |
|---|---|---|
| Bar mount | The mount fits the saw | A wrong mount cannot seat correctly |
| Pitch | Bar, chain, and sprocket agree | Mismatched pitch will not run properly |
| Gauge | Chain drive links fit the bar groove | A mismatch can cause poor fit or operation |
| Drive-link count | Chain matches the bar length and layout | Length is not determined by bar length alone |
| Oil delivery | Oil reaches the chain during operation | The bar and chain need lubrication |
Before use, check the chain brake, throttle lockout, stop switch, chain catcher, handles, bar rails, sprocket, tension, and oil delivery. Use suitable bar-and-chain oil for the conditions; there is no single universal viscosity or flow setting for every job. Check that the chain receives oil, and set depth gauges to the chain maker’s specification rather than assuming one clearance fits all.
Safe operation for ground-based work
Safe operation means keeping the saw under control and matching each cut to the wood and site. The 570’s power does not reduce the need for training or careful planning. Wear suitable protective equipment, follow the manual, and do not fell trees beyond your skill, equipment, or control of the work area.
Before starting, inspect your footing, escape routes, overhead hazards, and nearby people and property. Wear a helmet, eye and hearing protection, chainsaw-rated leg protection, gloves, and suitable boots. Follow applicable OSHA requirements and ANSI Z133 practices where they apply.
Start on stable ground with the chain brake engaged, following the manual’s cold- or warm-start steps. Never drop-start the saw. Before cutting, verify that the chain stops at idle and that the brake works. Hold both handles firmly, keep stable footing, and do not cut above shoulder height or force a dull chain through wood.
Rotational kickback can happen when the upper quadrant of the bar nose contacts wood or another object. The saw may rotate rapidly upward and backward. Keep the nose clear, avoid tip-first contact, and maintain a firm two-handed grip. A chain brake and low-kickback equipment are important safeguards, but neither makes intentional nose contact safe.
For felling, assess lean, wind, defects, and nearby hazards, then plan an escape path and make cuts suited to the tree and conditions. If the tree or site is beyond your training, stop and use a qualified professional.
Maintenance, sharpening, and tuning
Routine maintenance means checking and cleaning parts that affect airflow, lubrication, control, and safe operation. On an older 570, careful inspection can reveal wear that a quick engine start will not. Replace damaged parts before work, and use the manual and chain maker’s instructions for service limits and settings.
Clean the air filter and cooling fins. Inspect the spark plug, fuel lines, anti-vibration mounts, clutch area, brake band, bar groove, oil holes, and sprocket. Clear debris and look for cracks, unusual wear, or damage. A saw that runs is not automatically a saw that is safe to use.
Sharpen the chain with the file size, cutter angles, and depth-gauge settings specified by its manufacturer. Check tension when the chain is cool. After adjustment, it should sit on the bar without sagging and move by hand with gloves on.
Use fresh fuel mixed at the ratio specified for the oil and manual. With Husqvarna two-stroke oil, the stated mix is 50:1; if using another approved oil, follow the applicable instructions. Never run gasoline without two-stroke oil or guess the ratio. Carburetor adjustment and maximum-speed checks need the correct service procedure and a tachometer. Do not tune by ear or exceed the manufacturer’s limit.
Storage and seasonal care
Good storage limits preventable wear and help the saw start safely when needed again. After work, shut down, engage the brake, let the saw cool, and remove chips, resin, and debris from the bar, chain, sprocket cover, and air intake. Correct defects before the next use.
For extended storage, follow the manual’s fuel-system procedure and store fuel safely. Protect the bar and chain, keep the saw dry, and prevent access by unauthorized users. Before returning it to service, repeat the safety and function checks rather than assuming storage preserved its condition.
Choosing a 570 and checking a used saw
A used 570 can make sense when its condition, compatible parts, and local service support are clear. A low price is less useful if the saw needs major repair or has an uncertain origin. I treat a seller’s description as a starting point, then verify the machine and its setup.
| Buying scenario | What to verify before deciding |
|---|---|
| Used saw with bar and chain | Manual match, bar markings, chain fit, oil delivery, brake function |
| Powerhead only | Exact version, compatible mount and sprocket, parts availability |
| Saw advertised as “professional” | Model identity, condition, maintenance history; do not rely on the label |
| Unusually low-price listing | Seller identity, serial and product labels, proof of purchase, safe inspection |
| Saw needing tuning | Have a qualified service provider check it; avoid unverified carburetor changes |
Ask for clear photographs of the product identification labels and serial number, and compare them with the saw’s documentation or ask an authorized Husqvarna dealer to help identify the version. A serial number alone does not prove authenticity or condition. Be cautious of missing labels, altered markings, mismatched parts, or a seller who will not allow reasonable checks.
A practical field scenario: imagine two used 570s at similar prices. One starts, but has a damaged brake band and a bar-and-chain combination the seller cannot identify. The other has clear identification, a working brake, and documented service. The second is the more verifiable purchase, even before negotiating price. This is a decision example, not a claim about a specific sale.
