Fenwick Forklift trucks, diesel (EVO series)

Additional Notes

• All six EVO series models listed — H50D, H60D, H70D, H80D, H80/900D, and H80/1100D — share identical cooling system capacities and service intervals, despite spanning a range of load capacities from 5,000 kg to 11,000 kg. All are equipped with the Deutz TCD4.1 L04 engine with SCR (Selective Catalytic Reduction) emissions treatment, introduced from 2016.
• The base cooling system capacity across all six models is 14 liters. This figure represents the volume of coolant the system holds without any auxiliary heating equipment fitted.
• When a cab heater is installed, the cooling system capacity rises to 16.5 liters across all listed models. The additional 2.5 liters accounts for the coolant volume held within the heater circuit, which is integrated into the main cooling loop.
• The coolant level check interval is set at every 10 operating hours under normal use conditions. A 10-hour interval is notably short and reflects the demanding duty cycles typical of industrial forklift operation, where overheating risks are elevated by sustained low-speed, high-load work.
• The coolant change interval is defined by a dual condition: 24 months or 6,000 operating hours, whichever comes first. The time-based limit of 24 months applies even in low-usage situations where the hour threshold may not be reached, since coolant degrades chemically over time regardless of use.
• The 6,000-hour threshold for coolant replacement is relatively high for industrial equipment, suggesting the specified coolant formulation is a long-life type capable of maintaining corrosion inhibitor effectiveness over extended service periods.
• All specifications apply under normal use conditions. The absence of a separate severe-use interval means the 10-hour check and 24-month/6,000-hour change schedule represent the single defined maintenance standard for these models.
