In addition the 8-Series features a redesigned chassis and a durable engine hood and stamped steel side panels that improve the new models’ ability to stand up to harsh working environments. The 8-Series also has a unique electrical system with weatherproof connectors that isolates critical controls from pressure washing and an improved cooling system improves airflow through the radiator and counterweight to reduce overheating. Other enhancements include a drive-train protection option that only allows directional switches at less than full speed, an optional wet brake system for long life, improved visibility, better operator ergonomics as well as a number of design features designed to reduce maintenance requirements.Source: Toyota Material Handling U.S.A.
