Necessary preparations prior to the winter season
•
If necessary, replace the engine oil and hydraulic oil with those of the specified viscosities.
•
Only use regular diesel fuel with winter additives. Do not mix petrol and diesel fuel.
•
Check the battery's state of charge. In case of extremely low temperatures, it may be necessary to remove
the battery after work and store it in a heated room.
•
Check the antifreeze strength in the cooling system (page 104). If necessary, add antifreeze until the
protection ranges from -25 °C to -40 °C.
•
Apply talcum powder or silicone oil to all rubber seals at the windows, the cab door and the side window
guide rails.
•
Lubricate all locks, except the starter switch, with graphite lubricant.
