This moulded plastic cover shields the air filter and carburettor intake area from sawdust, wood chips, fuel mist and moisture during cutting work, maintaining clean airflow through the filter and helping prevent premature filter clogging and carburettor contamination. A direct replacement for cracked, damaged or missing covers, it clips into the original fixing point on the saw without tools for straightforward field or workshop replacement. Available from Gustharts, an authorised STIHL dealer, with UK stock ready to ship.\u003c\/p\u003e\n\n\u003cp\u003eThe MS 200 T is a top-handle arborist chainsaw widely used in UK tree surgery for pruning, dismantling and aerial cutting work — an environment where constant exposure to airborne debris makes a correctly seated, undamaged filter cover essential to reliable engine performance. Always confirm your machine's model and serial number against the compatibility list before ordering spare parts for the MS 200 range.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGenuine STIHL OEM part\u003c\/strong\u003e — correct dimensions and fixing geometry for assured filter and carburettor sealing on the MS 200 and MS 200 T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart number 1129 140 1902\u003c\/strong\u003e — also referenced as 1129-140-1902 and 11291401902 across STIHL documentation and ordering systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCovers and seals both air filter and carburettor intake area\u003c\/strong\u003e — preventing debris ingress at the filter housing and carburettor box during cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable moulded plastic construction\u003c\/strong\u003e — resistant to fuel mist, oil splash, workshop contaminants and impact from normal site use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupports correct filter seating\u003c\/strong\u003e — maintains proper filter-to-housing seal to reduce premature clogging and maintain clean airflow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool-free clip-on fitting\u003c\/strong\u003e — clips onto the original fixing point on the saw for quick, straightforward field or workshop replacement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect replacement for 020 and 020 T models\u003c\/strong\u003e — the MS 200 and MS 200 T are the updated designations for the earlier STIHL 020 and 020 T;

If the cover warps, flexes, or doesn't mate precisely with the filter housing due to dimensional variation, the filter can unseat under vibration, creating a direct path for debris to reach the carburettor. On a top-handle saw used in aerial arborist work — where cutting position and angle change constantly — this risk is compounded.\u003c\/p\u003e\n\u003cp\u003eSTIHL — the world's largest manufacturer of handheld power tools — manufactures genuine OEM parts to match the exact dimensional tolerances of the original component, ensuring correct filter compression, secure housing closure and a consistent debris seal across the full range of cutting angles. For a low-cost item where the failure mode directly affects engine protection, the difference in price between genuine and aftermarket is rarely worth the risk.\u003c\/p\u003e\n\n\u003ch2\u003eAlso Known As\u003c\/h2\u003e\n\u003cp\u003eThis part is officially listed by STIHL UK dealers as the \u003cstrong\u003ecarburettor box cover\u003c\/strong\u003e, which reflects its dual role in protecting both the air filter housing and the carburettor intake area. It is also commonly referred to as an \u003cstrong\u003eair cleaner cover\u003c\/strong\u003e, air box cover, filter cover lid, air filter lid, filter housing cover and carb cover.
