Operation
Operating the working lights
The starter switch is in the RUN position.
Press the working light button (1). Both the working lights
and the instrument lighting are turned on.
Press the button again to switch off.
During work on public roads other road users must
not be blinded.
Cold weather operation
Operating the excavator at an ambient temperature below 5 °C is regarded as cold weather operation.
Necessary preparations prior to the winter season
If necessary, replace the engine oil and hydraulic oil with those of the viscosities specified for winter.
Only use regular diesel fuel with winter additives. Do not mix petrol and diesel fuel.
Check the battery (page 98). 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 89). If necessary, add antifreeze until the protec-
tion ranges from -25 °C to -40 °C.
Operation during the winter season
The excavator must be cleaned after work is finished (page 89). Special attention must be paid to the
crawlers, the front attachments and the piston rods of the hydraulic cylinders. If the excavator is cleaned
with a water jet, it must then be parked in a dry, frost-free and well-ventilated enclosed space.
If necessary, park the excavator on boards or mats in order to prevent freezing to the ground.
Before starting, check if the piston rods of the hydraulic cylinders are free of ice to avoid damage. Also
check if the crawlers are frozen to the ground. If so, do not take the excavator into operation.
Be careful when getting on and off, the crawler could be slippery.
Do not put a load on the excavator immediately after starting. Before you start working with the front at-
tachments, warm up the excavator until the operating temperature is reached. Do not warm up the excava-
tor at idling position
