OPERATION
F 92 F 93
IMMEDIATELY AFTER STARTING
After starting set the engine
speed to 800 up to 1000 RPM
and let the engine idle for 3
minutes without load.
In this time check for proper lubrication,
charging (indicator lights must be “off“)
and other functions assuring the correct
engine operation. Time of engine idle
without load must be kept especially in
winter season.
PREHEATING THE ENGINE
Continue with farther preheating the engine already while driving. Warming
up the engine by long idle run or fast increase of speed is dangerous for the
engine.
Do not exceed engine speed above 2 000 RPM until the coolant temperature
reaches 45°C.
