37 1 Scope
38 This document provides product group specific guidance for a common understanding of measures, given by
39 any legislation, to define product specific information on the repairability and the reuse of used parts of motor-
40 operated hand-held tools, transportable tools, lawn and garden machinery. It is based on the following aspects:
41 • the inherent technical possibility/features to repair a product;
42 • the ability of the person repairing the product (skill level and tools);
43 • the possibility to reuse used parts of a product;
44 • the ability during repair for software updates.
45 The decision whether a product should be repaired is dependent on a range of factors such as health and
46 safety, intended use as well as economic, legal, and environmental aspects. However, the question of whether
47 it is reasonable to repair the product or reuse of used parts is outside of the scope of this document. This
48 document does not cover software (firmware and application software) or hardware modifications that change
49 the intended use of the product. Other risks making products non-compliant with safety standards are also
50 not covered by this document. The safety of the repairer during the repair is out of scope of this document.

120 4 Prerequisites for repair
121 4.1 General
122 The repairability of a product is conditioned by a number of prerequisites, which, often by law, shall be met in
123 advance of the repair process. The following list is a non-exhaustive overview over some of the general aspects
124 which shall be taken into consideration.
125 NOTE In order to determine a comparable index of repairability, it makes sense to distinguish between possible repairs
126 and those that are not permitted to be performed by the end user due to safety legislation.
127 4.2 Skill level required for repair
128 Repairs are distinguished according to their complexity level as follows:
129 Complexity level of the repair A: No tools are needed or only commercially available tools. No safety-critical
130 spare parts and no special tests or calibration needed when the repair is carried out in accordance with the
131 instruction manual. Opening of the core product is not necessary.
132 Complexity level of the repair B: Special tools, but no safety-critical spare parts and no calibration needed
133 when the repair is carried out in accordance with the repair manual. Opening of the core product might be
134 necessary.
135 Complexity level of the repair C: Special tools, safety-critical spare parts and, if necessary, calibration
136 needed when the repair is carried out in accordance with the repair manual. Opening of the core product
137 might be necessary.
138 The skill levels of repairers are defined as follows:
139 Level 1 end user: person that can only perform the repair as described in the instruction manual.
140 NOTE For safety reasons, the repair of certain products or parts is not permitted to be performed by the end user,
141 including, without limitation, the following:
142 • Reset an immobilizer system or security-related electronic modules;
143 • Reprogram any electronic processing units or electric motor control units;
144 • Change any equipment or electric motor settings negatively affecting safety compliance;
145 • Download or a
