OPERATING INSTRUCTIONS
Fuel economy and engine performance is also directly related to driving
habits:
• The best results in trip time and fuel economy are obtained while
driving the vehicle at a steady speed.
• Shift into higher or lower gears (or apply the service brake) to keep
engine rpm near the lower end of the optimum operating range.
• Avoid rapid acceleration and braking.
Fuel - Excessive Consumption
The vehicle’s fuel consumption is connected to three important factors -
maintenance, driving habits, and general condition of the road (including
traffic conditions and vehicle load).
Maintenance Factors Affecting Fuel Consumption
Correct maintenance will keep the vehicle running like new even after
long periods of use. The driver must perform daily and weekly checks of
the vehicle for:
• engine valves out of adjustment
• injection pump improperly synchronised
• injection nozzles defective or uncalibrated
•
improperly inflated tyres
• wheel bearings incorrectly adjusted
• dragging brakes
• clutch incorrectly adjusted or worn (slipping)
• fuel leaks
• clogged up charge air cooler
