Stihl MS 460 Chainsaw (Full Specs)
The STIHL MS 460 is a 76.5 cm³ professional two-stroke chainsaw rated at 4.4 kW (6.0 bhp). Its power suits demanding felling and bucking, not casual pruning. A common setup uses a 20-inch bar, but bar and chain fit vary by version. Check the saw’s exact specifications, condition, and safety systems before buying or cutting.
If you are comparing used saws, the MS 460’s displacement and power can look compelling. But a large engine does not tell you whether a particular saw is sound, whether its bar and chain match, or whether it suits your work. I would treat the listed specifications as a starting point, then verify the saw’s identification, components, and condition.
STIHL MS 460 specifications at a glance
These figures describe the core MS 460 setup: engine size and output, tank capacities, and common chain dimensions. They help you compare models and plan a compatible cutting setup, but they do not confirm the condition of a used saw or guarantee that every market version has identical parts.
| Specification | MS 460 figure or guidance |
|---|---|
| Engine displacement | 76.5 cm³ |
| Rated power | 4.4 kW (6.0 bhp) |
| Idle speed | Approximately 2,500 rpm |
| Maximum no-load speed | Approximately 13,500 rpm |
| Fuel mixture | 50:1 with STIHL two-stroke engine oil |
| Fuel tank capacity | Approximately 0.80 L |
| Chain-oil tank capacity | Approximately 0.32 L |

| Common bar setup | 20 in.; confirm exact saw and bar compatibility |
“Pitch” is the spacing between chain rivets, while “gauge” is the thickness of the drive links that sit in the bar groove. Both must match the bar and sprocket. Do not order a chain from bar length alone: check the bar stamp and count the chain’s drive links.
The idle and maximum-speed figures are approximate reference points, not instructions for carburetor adjustment. Version, condition, and service requirements matter. A technician should check and tune the saw against the applicable service specification with a tachometer.
Power, weight, and bar choice
The MS 460’s 4.4 kW rating identifies it as a high-power saw for demanding cutting, but power is only one part of the buying decision. The saw’s weight, bar length, chain condition, and your experience all affect control. Choose the shortest approved bar that can safely handle the work.
The powerhead weighs about 6.6 kg (14.6 lb) without the bar and chain, fuel, or chain oil. That distinction matters: the ready-to-cut saw weighs more, and longer cutting equipment adds weight farther from your hands. A longer bar can reach farther into large wood, but it also increases leverage and kickback exposure.
A 20-inch bar is a common configuration, not a universal recommendation. Check the bar and chain against the exact model and version. A long bar may suit certain large-wood cuts, but it requires more skill and can make the saw harder to manage. Do not select one only because the engine is large.
| Work scenario | What to consider | Practical check |
|---|---|---|
| General bucking of suitable logs | A shorter, compatible setup can be easier to control | Confirm wood size, bar fit, and chain condition |
| Large-diameter wood | Reach and cutting method matter; a longer bar may be needed | Verify the approved bar range and operator skill |
| Felling | Tree condition, lean, escape path, and site risks guide the plan | Do not rely on bar length to make a difficult tree safe |
| Pruning or overhead work | The MS 460 is not a pruning saw | Do not cut above shoulder height |
Buyer scenarios to test the fit
These examples are decision checks, not reports of field tests. If your work is mostly small limbs and light cleanup, the MS 460 is likely more saw than you need. If you regularly buck large logs and have the training and safe work area for a powerful saw, its output may be useful. For felling, assess the tree and site first; engine size alone does not make the job appropriate.
Before buying a used unit, verify the model marking and version, then inspect the bar, chain, sprocket, and safety controls. Ask for service records if available. A low asking price does not offset a damaged chain brake, poor compression, fuel-system problems, or missing parts.
Fuel, chain, and bar compatibility
The MS 460 uses a two-stroke engine, which needs the correct fuel-and-oil mixture for lubrication. Use fresh fuel mixed at 50:1 with STIHL two-stroke engine oil, and follow the instructions for the saw and oil. Straight gasoline or an incorrect ratio can cause rapid engine damage.
The common chain setup is 3/8-inch pitch and .063-inch gauge, but confirm every component before buying replacements. The chain must match the bar and drive sprocket, and its drive-link count must match the bar length and model. A bar stamp and the saw’s manual are better guides than a seller’s description.
The chain-oil tank holds about 0.32 L and the fuel tank about 0.80 L. These capacities do not establish how long the saw will run or how much oil it will use; cutting conditions and oil adjustment affect that. Use dedicated chainsaw bar-and-chain oil, check that oil reaches the chain, and adjust delivery only within the manual’s range.
Pre-start safety and cutting checks
A pre-start check is a short inspection of the controls, cutting gear, and work area before the engine runs. It can reveal problems that a specification sheet cannot. Wear chainsaw-rated head, eye, and hearing protection, gloves, leg protection, and protective boots, then follow the correct manual for starting and operation.
Check the chain brake, throttle lockout, stop switch, chain catcher, handles, fasteners, chain tension, bar rails, and lubrication system. Keep bystanders outside the work zone. Before cutting, assess overhead hazards, tree lean and defects, escape routes, nearby people or property, and whether wood is under tension or compression.
Start the saw on stable ground with the chain brake engaged, following the cold- or warm-start instructions for that version. Never drop-start it. Confirm a stable idle and visible chain-oil delivery before cutting. Keep a firm two-handed grip and a balanced stance, and keep the bar out of soil and debris.
For felling, a planned notch and controlled back cut help guide the tree, but hinge requirements depend on the tree and conditions. Do not use a fixed hinge size as a universal rule. Do not fell near people or structures without a competent plan. Apply ANSI Z133 and, where applicable, OSHA 29 CFR 1910.266 requirements.
Rotational kickback can occur when the upper quadrant of the bar nose contacts wood, throwing the bar rapidly back and upward. Keep the nose clear unless you are trained and equipped for that technique. A working chain brake can reduce risk, but it does not make nose contact safe.
Maintenance, sharpening, and storage
Routine care helps preserve cutting performance and can reveal wear before it becomes a larger problem. Follow the correct manual for service steps and intervals. If a safety device fails, stop using the saw until it has been repaired and checked.
Sharpen the chain to its manufacturer’s cutter and filing-angle specifications. Set depth gauges with the matching tool; 0.025 in. (0.65 mm) is not a universal setting for every chain. Replace a damaged or excessively worn chain rather than trying to sharpen away serious defects.
Clean the bar groove and oil hole, inspect the rails for wear or spreading, and rotate the bar as specified. Clean the air filter and cooling fins, and inspect the spark plug, fuel lines, anti-vibration mounts, chain brake, and sprocket. Use a tachometer and the applicable service specification for carburetor tuning and maximum-speed checks. Do not tune by sound alone.
For fasteners, use the service manual for the exact model and version. Generic torque values are not safe substitutes for specifications covering critical parts such as the clutch or flywheel.
Before storage, follow STIHL’s instructions and local rules for emptying or stabilizing fuel. Do not leave stale mixed fuel in the saw. Clean the saw, bar, and chain, protect cutting parts from corrosion, and store the unit dry and secure, away from children. Before returning it to service, inspect the fuel system, safety devices, chain tension, and oil delivery.
Is the MS 460 the right saw for you?
The MS 460 makes most sense when its power matches demanding cutting and its weight and handling suit the operator. It is not a default choice for small cleanup, pruning, or occasional light work. A well-maintained, correctly configured saw is more useful than a larger model with the wrong bar, worn parts, or failed safety controls.
If you are shopping used, confirm the exact version, specifications, and component fit before comparing price. Have a qualified service professional assess concerns about engine condition, tuning, or safety systems. The key takeaway is simple: match the saw to the work, and verify the individual machine rather than relying on the model name alone.
