7.10 Winter operation
With operation in the winter, the machine can be used only up to a
temperature of 0 °C. The machine must not be operated without protection
covers .
If you use the machine at low ambient temperatures, you must also take the
following points into account:
− Prepare the workstation accordingly.
− Do not use frozen material.
− Only use winter diesel as fuel.
➢ Due to special additives it is also flowable at low temperatures.
Summer diesel can gel in the lines and clog them.
− Only use motor oil whose viscosity corresponds to the outside
temperature.
− If the temperature is extremely low, remove the battery in the evening
and store it in a warm room. The battery may be reinstalled only shortly
before starting the machine.
− If the battery is not maintenance-free, ensure that the acid level (10-15
mm above the top of the plate) and the acid density are correct. Check
the acid density regularly with a standard acid tester.
