TM 11-6615-241-35-1-2 Planned Maintenance and Lubrication Engine Coolant Check WARNING • Do not remove the radiator cap when the  engine     is   hot;   steam   and   hot coolant can escape and burn personnel. • Use extreme care when removing the radiator     pressure     cap.          Sudden release    of    pressure    can    cause    a steam   flash   which   could   seriously injure  personnel.    Slowly  loosen  cap to  the  first  stop  to  relieve  pressure before     removing     cap     completely. After use, securely tighten cap. • Use a clean, thick waste cloth or like material  to  remove  the  cap.    Avoid using   gloves.      If   hot   water   soaks through  gloves,  personnel  could  be burned. Inspect the coolant level in the overflow bottle only.  Do not remove the cap. The coolant level should be at the "Cold Level" line on the coolant recovery bottle. NOTE The lift truck cooling system is filled with  factory-installed solution of 50% permanent-type  antifreeze  and    50% water  containing  rust  and  corrosion inhibitors.  You should leave it in the truck year-round. Battery - Water - Fill Type Check the battery to be sure the cells are all filled. Inspect for cracks.  If the terminals are corroded , clean and protect them. Planned Maintenance and Lubrication Brake Reservoir Fluid Level Check Check brake fluid level by opening inspection/fill cap on brake reservoir mounted on left side of dash. IMPORTANT USE SAE D.O.T.  3 AUTOMOTIVE HYDRAULIC BRAKE FLUID ONLY. E-99
