Pay special attention to routine maintenance of the battery. It requires special
tools, measuring appliances and skilled attendants. If necessary, ask for help
by an authorised service in order to inspect or to recharge the battery,
particularly after a longer operational break exceeding 50 days. A longer
storage time might also cause a drop of battery potential needed for the next
start before new season.
Recharge the battery to full capacity also before longer break or storage,
particularly in winter.
Service life of the battery installed in the machine is rather limited. It is usually 3-4
years and after this period the battery should be replaced by a new one.
Hot-dip galvanized parts:
So-called white corrosion may occur on their surface – however, it is only an
optical problem.
To eliminate this problem, take the following measures: when putting the trailer
aside (or for storage), keep it in sufficiently ventilated space. After work in winter,
rinse the hot-dip galvanized parts with clean warm water or by a steam jet.
