Cold Weather Operation; Necessary Preparations Prior To The Winter Season; Operation During The Winter Season - Kubota K008-3 Operating Instructions Manual

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 specified viscosities.

Only use regular diesel fuel with winter additives. Do not mix petrol and diesel fuel.

Check the battery's state of charge (page 107). In case of extremely low temperatures, it may be neces-
sary to remove the battery after work and store it in a heated room.

Check the antifreeze strength in the cooling system (page 99). 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 99). 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.
Start the engine (page 61). However, make sure to do the following:

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.
