- Make sure that equipment is firmly seated before lifting it. Risk of personal injury and equipment damage! Due to a high center of gravity, some equipment can tend to tip over and cause damage to persons and property. - When transporting the unit, carefully observe its behavior and do not get near any possible hazardous areas. Delivery dimensions and weights The dimension and weight of each package can be seen below. -
Page 8: Disassembly And Re-Assembly
2.1.5 Disassembly and re-assembly Before starting any disassembly or re-assembly operation, please ensure that the product is isolated from its mains electrical supply, in order to ensure that fans cannot be run. As disassembly and re-assembly are not part of routine maintenance, these should be carried out by qualified personnel. Ensure that the hydraulic circuit is switched off. - Page 9 Fig. 4 It is recommended to put a soft pad on the ground or on the transport tool to avoid damage while turning the unit upside down. Important notes: 1. The ventilation ducts must not become kinked. 2. The connections to the connection valves must be firm and tight. 3.
