FS 111 OEM Parts

Shop genuine STIHL OEM parts for an FS 111 trimmer or brushcutter for maintenance, repairs, and component replacement. Search by OEM number, machine version, and system, then confirm the product title, description, quantity, and stated fitment before ordering.

Begin With the Actual FS 111 Repair Need

Start with the symptom and examine the whole system connected to it. Difficult starting, fuel leakage, poor engine response, a throttle-control concern, vibration, a worn drive component, a loose cutting head, or a damaged guard may have more than one cause. Do not replace a component based only on its appearance. Identify the source of the problem, inspect nearby connecting parts, and make a list of everything needed to complete the repair.

FS 111 Parts by Repair System

Depending on current inventory, this collection may include genuine STIHL FS 111 OEM components for these maintenance and repair areas:

• air filter, intake, carburetor, fuel tank, fuel line, filter, vent, and fuel-system parts;
• starter assembly, recoil rope, pulley, spring, grip, ignition, wiring, and switch components;
• throttle trigger, lockout, control cable, stop control, handle, and control-system hardware;

• cutting head, guard, deflector, blade or line attachment components, and fasteners;
• engine, cylinder, piston, crankcase, gaskets, seals, caps, covers, clips, and service hardware.

Use the repair system to narrow your search, then verify every product page. Confirm whether it is a part, kit, or assembly, its OEM number, FS 111 fitment, quantity, included items, and installation hardware required separately.

Inspect Drive and Cutting Attachment

The clutch, shaft, gearbox, and cutting attachment work together. Check the shaft tube, clutch connection, drive shaft, couplings, gearbox, guard, deflector, cutting head or blade mount, and fasteners for wear, cracks, looseness, or abnormal vibration. Keep the area free from debris and use the cutting attachment approved for your specific FS 111 configuration. Do not operate equipment with a damaged guard, loose attachment, worn coupling, or incorrectly fitted drive component.

Allow the engine to cool before servicing the cutting end. Secure the equipment, use appropriate protective gear, and follow STIHL information for the tool and approved attachment. Do not force a threaded head, guard mount, gearbox housing, or drive-shaft component. For clutch, gearbox, shaft, or attachment work outside your experience, ask a qualified outdoor-power-equipment technician for assistance.

Check Fuel and Starting Systems

Hard starting, stalling, low power, irregular idle, fuel leaks, or starter problems can have several causes. Inspect the connected system in order before selecting replacement parts. Fuel issues may involve the tank, line, filter, vent, connection, seal, or carburetor. Starter service may involve the rope, pulley, spring, grip, housing, ignition, wiring, or fasteners. Use illustrated parts information to build a complete FS 111 repair order.

Restore Safety Components Before Operating

Before returning the FS 111 to work, check the throttle trigger, lockout, stop switch, handle mounts, shaft tube, guard, deflector, attachment hardware, and visible fasteners. Replace parts that are loose, damaged, missing, cracked, or not operating normally. Follow STIHL operating and service guidance for your exact equipment configuration. Do not operate the trimmer or brushcutter until the controls, guard, and cutting attachment are correctly installed and secure.

Request FS 111 Parts Help

If you need help locating a component, provide the FS 111 model designation, serial number, OEM part number if known, and a clear photo or description of the part’s location. State whether the repair involves the engine, controls, shaft, gearbox, or cutting attachment. This helps narrow the search, while final compatibility should be verified against the product listing and illustrated parts information.

Know When Professional Service Is Needed

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

FS 111 Parts FAQ

How do I identify the correct FS 111 part?

Use the original OEM number when possible. If it is unavailable, use the exact model, serial information, illustrated parts diagram, and the component’s mounting location.

Can I use an FS 91 or other STIHL trimmer part on an FS 111?

Do not assume compatibility. Confirm the OEM number and stated FS 111 application because shafts, controls, gearboxes, guards, and cutting attachments can differ.
