Always put the generator set in OFF mode and activate the Start Inhibit switch (if equipped) before cleaning the radiator core. If the generator set is in AUTO mode, the generator set may start automatically, without warning.
Due to the large volume of air flowing across the radiator, debris may be pulled into the radiator, clog the fins, and reduce air flow. Reduced air flow across the radiator reduces the cooling efficiency of the radiator and may cause the generator set to run hotter or overheat. Periodic cleaning of the radiator core is recommended to ensure proper air flow.
Visually inspect the core for any obstructions, such as dirt or other foreign objects. Use running water to flush debris from between the fins.
NOTICE: DO NOT use hard objects to clean the radiator core. DO NOT use high pressure water to clean the radiator core. Damage to radiator could result. Radiator damage caused by improper cleaning is not covered under warranty.

FUEL SYSTEM MAINTENANCE

The fuel system pulls diesel fuel from the fuel tank, filters out water and other contaminants, then conveys it to the engine for combustion. Unused fuel is returned to the fuel tank through a return line. To prevent engine damage and excess wear, the use of proper fuels and proper fuel system maintenance is required.
Fuel Pump
The fuel pump installed on the generator set from the factory is capable of supplying enough fuel to the engine in a wide range of applications; however, installations with long fuel line runs and/or fuel tanks located too far below the generator set may require the use of a secondary fuel pump (not provided).
The fuel pump contains either a paper filter or mesh screen to prevent contaminants from damaging the pump. Periodic inspection and maintenance is required to maintain proper operation of the pump.
Fuel Lines
The fuel lines connecting the generator set needs to be a high quality, diesel & oil resistant, multilayer rubber hose. The hoses should also be resistant to temperatures of at least 212° F (100° C).
To provide an adequate supply of fuel to the engine, the hoses need to be sized appropriately.

Supply Line Size Minimum 5/16” (8mm)
Return Line Size Minimum 3/16” (5mm)

Fuel Specifications
It is recommended to run a clean, high quality diesel fuel with a minimum cetane rating of 50 in the generator set. The engine can operate on diesel fuels with a sulfur content up to 1.0% (10000 ppm); however, when using high sulfur fuels, with a sulfur content between 0.50% (5000 ppm) and 1.0% (10000 ppm), the engine oil and oil filter change interval is halved. DO NOT operate the engine on fuels with a sulfur rating greater than 1.0% (10000 ppm).
NOTICE: Always use diesel fuel. DO NOT use alternative fuels, such as bio-diesel or kerosene. Damage to the engine may result. Damage caused by using improper fuels is not covered under warranty.
NOTICE: The type of diesel fuel and sulfur content used MUST be compliant with all applicable emissions requirements in the area in which the generator set will be operated.
Bleeding the Fuel System

Draining Water from the Fuel Filters 

POWERTECH PTI-15 Mobile Generators - Figure 18warning 2 During operation, some parts of the generator set can become extremely hot. To avoid burns, allow the engine to cool sufficiently before draining the fuel filters.
Always stop the engine before draining the fuel filters. DO NOT drain the fuel filters while the engine is running.
Always put the generator set in OFF mode and activate the Start Inhibit switch (if equipped) before draining the fuel filters. If the generator set is in AUTO mode, the generator set may start automatically, without warning.
Water can get into the fuel system many ways including condensation in the fuel tank, contaminated fuel, or the generator set has not been used for an extended time. The fuel filter has an internal float inside the housing to indicate if water is present. When the float floats up, there is water present and needs to be drained. Use the following drain water from the fuel filters.
Primary Fuel Filter Replacement

  1. Shut down the generator set and put it in OFF mode.
  2. If equipped, activate the Start Inhibit switch.
  3. Ensure the generator set is on a level surface and properly supported.
  4. Allow the generator set to cool fully.
  5. Loosen the air bleeder plug at the top of the fuel filter
  6. Loosen the drain plug at the bottom of the case to drain the water into a suitable container.
  7. After the water is removed, tighten the air bleeder plug and drain plug.
  8. Reprime the fuel system to remove air from the fuel.

Changing the Fuel Filters

POWERTECH PTI-15 Mobile Generators - Figure 19During operation, some parts of the generator set can become extremely hot. To avoid burns, allow the engine to cool sufficiently before changing the fuel filters.
Always stop the engine before changing the fuel filters. DO NOT change the fuel filters while the engine is running.
Always put the generator set in OFF mode and activate the Start Inhibit switch (if equipped) before changing the fuel filters. If the generator set is in AUTO mode, the generator set may start automatically, without warning.
Water, dirt, and other contamination in the fuel can cause the engine to not operate properly, increase wear and/or engine damage. The fuel filters trap these contaminants before they reach the engine. Periodic replacement of the fuel filters is required according to the manufacturer’s schedule. Use the following steps to replace the fuel filters.
