DO NOT remove the radiator pressure cap (9), illust. Z24053
from a hot engine. Wait until the temperature is below 50°C
before removing the pressure cap (9). Failure to do so can
result in personal injury from heated coolant spray or steam.
Turn the radiator cap (9) slowly counterclockwise to the
safety stop to allow the pressure to escape, then continue to
turn until cap is free to be removed.
The coolant level should be in the upper field of the sight gauges
(7). If necessary add coolant.
REMARK
Refer to the Engine Operation and Maintenance Manual for
the correct coolant composition.
4.8.4
TRACK GROUPS - CLEAN
See (10), illustration Z24053.
Under working conditions with excessive material build up on the
crawler components, cleaning of the crawlers is very important to
prevent damage.
Material build up on guide wheels, drive sprockets and tracks can
lead to over tensioning of the tracks, resulting in severe damage
to these components.
If there is danger of frost, the tracks must also be cleaned.
NOTICE
Use a suitable cleaning device for removing dirt, mud and
debris from the tracks, rollers, guide wheels and sprockets.
