1.5.4 - SYMBOLS USED
2 - TOOL DESCRIPTION
2.1 - OPERATING SYSTEM
The hydropneumatic RIV938P tool, with oil pressure adjustment, is designed to place the following fasteners:
▶ RIVSERT female rivet nuts (from M3 to M10)
▶ RIVBOLT male rivet nuts (from M4 to M10)
The hydropneumatic system and the mechanical components used inside the structure of the RIV938P, when compared with other
riveting tools, results in greater reliability. Tool features reduce potential issues caused by the wear and tear of the components,
and consequently the tool will last longer and perform better. The technical solutions adopted make the RIV938P more compact and
lighter. The successful outcome is a very handy tool.
2.2 - VIBRATION
When used correctly and in compliance with the instructions given, the tool does not produce dangerous vibration.
2.3 - NOISE LEVEL
The tool is designed and manufactured to generate a very low noise level. The weighed equivalent of continuous acoustic pressure
level A in the operator position is below 80 dB (A).
2.4 - TECHNICAL DATA
The following table provides the technical data and features of the tool. Please refer to this table when contacting our Technical
Assistance Department.
SYMBOL MEANING COMMENT
P ... HAZARD This highlights a hazard with risk for the user.
A ... WARNING This points out a warning/note on key functions or useful information.
