4 Instructions for maintenance and service
4.1 For the execution of maintenance and service work, tools and workshop equip-
ment adapted to the task on hand are absolutely indispensable.
Work on the hydraulic system must be carried out only by personnel having special
knowledge and experience with hydraulic equipment.
4.2 Before putting into operation clean the machine, especially connections and threaded
unions, of any traces of oil, fuel or preservatives before carrying out maintenance/repair.
Never use aggressive detergents. Use lint-free cleaning rags and pay attention that the
components are meticulously clean during reassembling after repair.
4.3 During dismantling of machines it is necessary to collect the outrunning hydraulic
liquids completely, so that they cannot reach the ground. They have to be disposed
properly accord-ing to the instructions.
4.4 Always tighten any screwed and thread connections that have been loosened
during maintenance and repair. Observe the stipulated torques.
4.5 Work on the electrical system or equipment may only be carried out by a skilled
electrician himself or by specially instructed personnel under the control and supervi-
sion of such electri- cian and in accordance with the applicable electrical engineering
rules.
4.6 The electrical equipment of machines is to be inspected and checked at regular
intervals. Defects such as loose connections or scorched cables must be rectifi ed im-
mediately.

necessary to clean the whole machine if it must be exceptionally operated under such
conditions or gets into touch with these materials. Additionally, the machine must be
checked as described under 3.11.
