Disconnect Battery (Final Tier 4 and Stage IV Engines)

IMPORTANT: Important: Do not disconnect battery for at least 4 minutes after sprayer stops. Selective Catalyst Reduction system automatically purges lines of Diesel Exhaust Fluid (DEF) during this time, immediately after sprayer is stopped. If adequate time is not allowed for lines to be purged, any DEF remaining in lines can crystallize and plug lines. In freezing weather, DEF will freeze and possibly burst lines.
