Transporting and Storing the Cutting Cutters
• Danger of cutting caused by sharp cutting cutters.
• Serious injury, in particular to hands and fingers, can result.
• Wear protective gloves.
• Only transport and store the cutting cutters packaged.
• Grease the cutting cutters well, so that they do not rust. Protect the
cutting edges with doubled cardboard and use adhesive tape to
safeguard the cutters against slipping out of the sides of the sheath.
• After unpacking, you must de-grease the cutting cutters so that they
can be gripped safely.
Hydraulic Maintenance
Hydraulic oil has to be filled into the tank before start-up of the machine. The type of oil
that should be used depends on location. Recommend oils include type DIN 51524 HLP 32
for areas with temperatures below 32°F (0°C) in the winter and HLP 46 for temperatures of
around 86°F (30°C) in the summer. For extremely hot tropical areas (i.e. Thailand,
Malaysia, Nigeria etc.) it is recommended to use HLP 68. The first oil replacement should
be done after 1,000 operating hours and then after every 2,000 operating hours. The oil filter
must be replaced too.
