LAHDEK SCH1437 trimmer maintenance kit
The LAHDEK SCH1437 kit supplies an ignition coil, air filter, spark plug and fuel filter for petrol-driven STIHL trimmers and brushcutters. It is designed for owners of FS90, FS100, FS110, FS130R, KM90, HL95, HL100, HT100 and HT101 models who need a complete set of replacement parts.
Check model numbers and coil compatibility
Verify that your machine matches the listed models and cross-reference the original part numbers 41804001308 and 41801201800. The ignition coil will not fit units carrying 4180 1303 A MC2 1134 or HT101 # 4180 1301 coils, nor the R-suffix variants such as FS87R, FS90R, FS100R, HL100R, HL95R, KM90R, HT100R, KM100R or KM130R. Ensure the thickened section of the coil aligns with the original orientation and inspect the spark plug cap before fitting.
Sustained operation with fresh filters and spark
A clean air filter and new fuel filter maintain consistent fuel delivery during extended cutting sessions, while the fresh spark plug and matched ignition coil keep combustion stable under continuous load. This combination reduces the risk of power loss or misfire that can appear when individual components wear at different rates.

Questions about this item
Does the kit include everything I need for a tune-up, or must I buy the fuel line and gaskets separately?
The box contains one air filter, one ignition coil, one spark plug and one fuel filter; fuel lines, gaskets and mounting hardware are not included.
My trimmer is an FS 90 — will the coil in this SCH1437 kit fit, or do I need a different version?
The coil fits FS 90, FS 100, FS 110 and FS 130R models; it does not fit FS 87R, FS 90R or FS 100R variants, so confirm your exact model suffix before ordering.
The description warns about a thickened section on the coil — what does that mean when I install it on my HT 101?
The thickened portion of the coil must sit on the same side as shown in the product image, and the spark plug boot must match yours; otherwise the coil will not seat correctly on the HT 101.
