Introduction
This Special Instruction provides the information that is needed for installing the vented access door for the engine compartment. Overheating of the engine can occur during machine operations when the machine is equipped with a machine enclosure seal kit. The various seals, covers, and brushes that are used in the machine enclosure seal kits for blocking the entry of debris also reduce ventilation of the engine compartment. The vented access door that is provided in the 312-1024 Engine Enclosure Kit (VENTED) provides improved ventilation inside the engine compartment.Read the information and understand the information that is contained in this instruction before you begin installation.Parts Information
