dynamometer.
5.2.11 Preheating transmission
When the outside temperature is between –20°C and –25°C (–4°F and
–13°F), the gear oil must be preheated before you start driving the truck
crane.
Let the engine run at idling speed for at least 10 minutes before you start
driving.

Danger of unexpectedly moving off rollers
Always shift to the neutral position on the roller type dynamometer.
In position D or R, a suitable gear is engaged for the speed. The engine
braking power is applied against the rollers and the truck crane can drive
out of them.
