Dolmar typically places the model number on a label along the shaft or on the main housing near the engine. Check both areas, and clean away grass or oil if the label is hard to read. Look for a mix of letters and numbers, and copy it exactly, including spaces or suffixes. Enter that number in the search bar to filter the catalog to parts made for your complete string trimmer model, not just the trimmer head. If the label is missing, check the owner's manual or purchase records for the same information. Matching the model first helps you skip incompatible parts and order with confidence.

Routine wear items are the easiest way to keep your Dolmar String Trimmer Trimmer Head performing well between larger repairs. Repair Clinic stocks OEM consumables and wear items along with installation videos and part diagrams. Use the model number lookup to confirm the exact part for your unit, then order a spare so you have it ready for the next scheduled service.
