ELECTRICAL Removing and Installing Batteries: Batteries release gases that are flammable. Batteries are equipped with vent tubes and flash arrestors which vent battery gases out of the cab. Ensure all vent tubes, flash ar- restors and grommets are properly installed and ensure they are clear and functioning properly. Failure to reinstall or keep the vent tubes and grommets clear or ensure the flash arrestor(s) are functioning properly could result in personal injury or equipment damage. Failure to com- ply may result in death, personal injury, equipment or property dam- age. WARNING! Properly secure battery tie downs and battery box cover when rein- stalling batteries after service.
Do not over tighten. Over tightening can crack the battery case which can lead to equipment damage. CAUTION 1. Be sure all switches on the vehicle are turned OFF. 2. Wait 2 minutes after turning ignition off then disconnect negative ground cable first. 3. Disconnect positive cable. 4. Unscrew bolt of holding plate with open end wrench. The Diesel Exhaust Fluid (DEF) sys- tem purges to prevent damage from freezing. If your vehicle is equipped with battery disconnect switches, do NOT disconnect battery power within two minutes of switching the ignition key off. Failure to comply may result in vehicle or property damage.
