FS 131 OEM Parts

Find genuine STIHL OEM parts for an FS 131 trimmer or brushcutter for service, repairs, and replacements. Search by model, OEM reference, and system, then confirm the listing title, description, quantity, and stated fitment before ordering.

Use Repair Symptoms to Guide Your Search

Begin by identifying what the equipment is doing and inspect the full assembly connected to the issue. Difficult starting, fuel leakage, poor acceleration, a stop-switch concern, excess vibration, a loose cutting head, worn shaft parts, or a damaged guard may have multiple causes. Do not replace components just to test a theory. Find the source of the fault first, then select the parts necessary for a complete repair.

FS 131 Parts by Service Area

Depending on current inventory, this collection may include genuine STIHL FS 131 OEM parts for these common systems:

• air filter, intake, carburetor, fuel tank, fuel line, filter, vent, and fuel-system parts;
• starter housing, recoil starter, rope, pulley, spring, grip, ignition, wiring, and switch components;
• throttle trigger, lockout, stop control, cable, handle, and control-system hardware;
• clutch, drive shaft, shaft tube, gearbox, couplings, bearings, and mounting pieces;
• cutting head, guard, deflector, blade or line attachment components, and fasteners;
• engine, cylinder, piston, crankcase, gaskets, seals, covers, caps, clips, and service hardware.

Start in the category that matches your repair, then use the individual product page to verify the component. A listing can represent one part, a repair kit, or an assembly. Confirm the OEM number, quantity, stated FS 131 application, product details, and included pieces. Check whether screws, clamps, seals, clips, gaskets, or other supporting hardware is supplied or needs to be purchased separately.

Inspect Drive Shaft and Attachment

Inspect the shaft tube, clutch connection, driveshaft, couplings, gearbox, cutting head or blade mount, guard, deflector, and fasteners as one working area. Look for loose parts, damage, worn couplings, cracks, or abnormal vibration. Keep the cutting end clean and use the attachment approved for the exact FS 131 configuration. Do not operate the equipment with a loose cutting head, damaged guard, worn drive component, or improperly installed attachment.

Allow the engine to cool before working on the cutting end. Secure the machine and follow STIHL safety guidance for the tool and its approved attachment. Use the appropriate tools and do not force a threaded head, guard mount, gearbox housing, or shaft component. If you need help with clutch, gearbox, driveshaft, or attachment service, consult a qualified outdoor-power-equipment technician.

Check Fuel and Starting Components

Starting and engine symptoms can overlap. Hard starting, unstable idle, reduced power, fuel leakage, or recoil-starter trouble may involve the fuel tank, line, filter, vent, intake, carburetor, ignition, starter assembly, or internal engine condition. Inspect the connected system in order rather than replacing an item at random. Use the relevant parts information and product listings to prepare an accurate FS 131 repair order.

Confirm Safe Operation

Before using the FS 131, inspect the throttle trigger, lockout, stop switch, handle mounts, shaft tube, cutting guard, deflector, attachment hardware, and visible fasteners. Replace parts that are damaged, missing, loose, cracked, or not working normally. Follow STIHL operating and service information for your specific equipment configuration. Do not operate the trimmer or brushcutter until controls, guards, and the cutting attachment are installed correctly.

Request FS 131 Parts Help

If you need assistance locating an item, provide the FS 131 model designation, serial number, OEM reference if known, and a clear photo or description of the component’s position. State whether the repair involves the engine, controls, shaft, gearbox, or cutting attachment. This lets us narrow the search, while final fitment should always be verified against the product page and illustrated parts information.

Use Qualified Service

Internal engine, fuel-system, ignition, clutch, gearbox, driveshaft, and safety repairs can require specialized experience and tools. A parts catalog identifies components but does not establish the cause of a mechanical fault. For repairs beyond routine maintenance or your experience level, consult a qualified small-engine or outdoor-power-equipment technician.

FS 131 Parts FAQ

How do I find the correct FS 131 OEM part?

Use the original OEM number whenever possible. If you do not have it, use the complete model, serial information, illustrated parts diagram, and component mounting location.

Can I use an FS 111 or other STIHL trimmer part on an FS 131?

Do not assume compatibility. Confirm the OEM reference and stated FS 131 application because drive components, controls, guards, gearboxes, and cutting attachments can differ.
