CLEANING THE TRUCK: Clean the parts of the truck, except electrical and
electronic elements, with a damp cloth. Do not use direct jets of water, steam
or inflammable liquids. Clean electrical and electronic components with
dehumidified compressed air at low pressure (max. 5 bar) or with a non
metallic brush.
Use hydraulic oil apart from motor and brake oil. Note: When eliminating
used oil please respect the environment. The oil should be stored in a
drum that should be later consigned to the nearest petrol station. Do
not dump the oil in the ground or in unsuitable places.
