6.2. After-season maintenance
Follow instruction given in section 7: “Maintenance and storage”.
7. MAINTENANCE AND STORAGE
After the machine has been dismounted from the extension arm, for idle period longer than one
month, perform the following maintenance works:
 clean the machine thoroughly from any soiling and then wash and dry,
 if need be, perform any repairs, adjustments, replacement of sealing or hoses
 lubricate all lubrication points marked with special label as in Fig. 7,
 remove any sources of corrosion and complement any paintwork defects,
 protect non-painted metal surfaces with a thin film of a solid grease, e.g. ŁT – 43, or gearbox,
mineral or motor oil, e.g. 15W40,
 complement or replace illegible warning and information labels,
 close connection nozzles of hydraulic hoses.
 install the guard on the trimmer's cutting bars.
The machine should be stored in a standstill position in a dry and clean place, inaccessible to
unauthorised personnel and animals, on an even and paved ground under a roof or any other cover
protecting it from the weather.
When approaching operation after the machine's storage period, examine technical condition of
hydraulics and drive train as on daily basis, complement the paintwork, re-grease and examine
condition of hydraulic hoses.
8. TRANSPORT
When the machine is to be transported, make sure to install the guard on cutting bars. Cover the
machine with bubble foil and fix it on a pallet with duct tape. Any further moving of the machine
should be done with the fixed pallet, considered as its integral part.
To place the scissor trimmer on a pallet use belt suspension and lifting device with capacity of no
less than the trimmer's weight.
