Note (1)
Net Power advertised is the power available at the flywheel when
the engine is equipped with fan, air cleaner, muffler, and alternator
with engine speed at 1,800 rpm.
Note (2)
Power rating applies at 1,800 rpm when tested under the specified condition for the specified standard.
Note (3)
Ratings based on SAE J1995 standard air conditions of 25° C (77° F) and 100 kPa (29.61 Hg) barometer. Power based on fuel having API gravity of 35 at 16° C (60° F) and an LHV of 42 780 kJ/kg (18,390 BTU/lb) when engine used at 30° C (86° F).
Note (4)

Note
Operator selectable coverage: 0.1 - 0.8 L/m² (4 kph - 40 kph) / 0.05 - 0.2 gal/ft² (3 mph - 25 mph). Coverage rates above 0.6 L/m² may not be available at higher speeds depending on head count and configuration.
Note (1)
Spray head opening is automatically controlled by the system to achieve Auto Mode Coverage or manual mode flow rate.
Note (2)
The Auto Mode setting controls water coverage and automatically adjusts to the number of spray heads being used — independent of ground speed. This is an exclusive feature designed into the Cat WDS software to help water more efficiently. Water flow is continually adjusted during operation to conserve water and achieve desired coverage and flow rate.
Note (3)
Alternatively, manual mode allows the operator to set a water flow rate that is constant regardless of ground speed. This mode is not recommended for daily operation and will reduce watering efficiency and may increase fuel usage.
Note (4)
Spray heads on competitive water distribution systems require tools and maintenance to change flow and spray pattern. Caterpillar is the only company to have variable active spray heads to regulate water spray.
Note (5)
Cannon performance depends on nozzle orifice and pipe size.

Note (1)
Productive capabilities of the 777 truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production.
Note (2)
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection.
