Figure D-12 Replacing the retaining nut
The top and side tubing retaining nuts can be damaged if excessive force is applied
when replacing them. Take care not to cross-thread these nuts.
Looseness of the retaining nut may result in incorrect data. Tighten the retaining nut

Use only fuses that are specified in this Operator Manual, (see “Technical
specifications” on page F-2). The use of other fuses is a breach of the warranty.
