Operation
Operating the battery isolator
In order for the excavator to be operated, the battery isolator (1)
must be in the ON position.
A ON
B OFF
Cold weather operation
Operating the excavator at an ambient temperature below 5 °C is considered 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's state of charge (page 141). 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 fluid level and the antifreeze strength of the cooling system (page 69). The antifreeze strength
should be between -25 °C and -40 °C.
Lubricate all locks, except the starter switch, with graphite lubricant.
Operation during the winter season
The excavator must be cleaned after work is finished (page 132); Special attention must be paid to the crawl-
ers, 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.
Start the engine (page 77).
Switch the starter switch for approx. 10 seconds (rather than 5 seconds) to the PREHEAT position.
Let the engine warm up for approx. 10 minutes (rather than 5 minutes) at idle speed.
If the battery isolator is in the OFF position, all of the
electrically powered functions will be turned off (e.g.
engine horn, working lights, etc.).
The control unit are saved, and the battery discharges
itself only minimally.
Be careful when getting on and off, the crawler could be slippery.
