The Multiquip HS52010018A Air Filter Cover Long is a genuine OEM replacement designed for HS81A and SHS81A series high-speed cut-off saws. As a factory-sourced component, it ensures a correct, secure fit over the air filtration system — maintaining the tight tolerances the original design demands. This part is confirmed compatible with both MQ and STOW Sidewinder handheld cut-off saw models. Keeping this cover in good condition is essential to protecting your saw's air filter from dust, debris, and the heavy particulate load generated during cutting operations.
Key Features
- Genuine OEM Construction: — Manufactured to the exact material grade and dimensional spec of the original cover, ensuring a flush, gap-free seal around the air filter housing.
- Direct-Fit Replacement: — Engineered to drop into place on HS81A and SHS81A Sidewinder cut-off saws without modification, using the original mounting points and fastener pattern.
- Broad Sidewinder Compatibility: — Fits both the MQ High Speed Cut-Off Saw (HS81A) and the STOW High Speed Cut-Off Saw (SHS81A), covering both Multiquip portfolio brands in one part number.
- Air Filter Protection: — Shields the air filter element from concrete dust, masonry debris, and moisture ingestion — contaminants that accelerate filter clogging and engine wear when a cover is cracked, missing, or improperly seated.
- Dust Environment Compliance: — Cut-off saws operate in some of the harshest dust conditions on any jobsite; a correctly fitted cover is a front-line defense for engine air intake integrity and is not a cosmetic item.
The air filter cover on a handheld cut-off saw serves as the primary barrier between the engine's air intake system and the extreme levels of silica dust, concrete particulate, and debris generated during cutting. By enclosing and securing the air filter element, it prevents premature filter saturation and keeps unfiltered air from bypassing the element entirely — a condition that causes rapid cylinder and piston wear. A damaged or absent cover compromises every cut the saw makes and shortens engine service life significantly.
