The HUSQVARNA 545030501 is a spark arrestor kit designed to reduce the emission of combustible particles from the exhaust of small gasoline-powered outdoor power equipment. Spark arrestors are a required safety component on equipment operated in areas where fire risk is a concern, including national forests and other regulated lands. This kit provides the necessary parts for a proper spark arrestor replacement or installation and is intended for installation by a qualified small-engine technician or experienced power equipment service professional.
This spark arrestor kit is suited for use on HUSQVARNA gasoline-powered outdoor power equipment such as chainsaws, trimmers, and similar handheld or walk-behind units where exhaust spark arrestors are required by regulation or manufacturer specification. It is commonly installed during routine maintenance or when the existing arrestor screen shows signs of clogging, damage, or burnout.
Designed as an OEM replacement spark arrestor kit for applicable HUSQVARNA outdoor power equipment. Refer to your equipment model and parts diagram to confirm fitment before installation.
Installation should be performed by a qualified small-engine technician or experienced service professional. Shut down and allow the engine and exhaust system to cool completely before beginning any exhaust or muffler service. Inspect the muffler and exhaust port for carbon buildup or damage while the arrestor is removed. Follow all applicable local and federal regulations regarding spark arrestor use on outdoor power equipment.
