GENERAL INFORMATION

MANUFACTURER

Rivit S.r.l. was born in 1973, it produces and distributes in Fasteners and Tools for Fixings (tools for rivets and rivet
nuts). The Company boasts much technical experience and offers a wide range of products related to fastening
systems.

ASSISTANCE

In case you need any assistance concerning the use and the maintenance of the tool, or in case you need to order
any spare parts, you shall contact your local authorised dealer (or Rivit S.r.l. directly) specifying the identification/
serial numbers of the tool, written on its outer casing.

CERTIFICATION AND EC MARKING

The tool is manufactured in compliance with the European Directives, which are in force when the tool itself is put
on the market. As the tool is not included in ENCLOSURE IV of DIRECTIVE 2006/42/EC, Rivit S.r.l. issues a self­certification to apply the EC marking.

WARRANTY

The warranty has a validity of 12 months, as of the date indicated on the invoice.
The warranty only covers replaced parts; labor is not included.
The following are not covered by warranty: standard accessories (see section 2.5) and tool damages caused by:

• transport and/or handling, user’s mistakes,

• failed servicing/maintenance, as indicated in section 7 of this manual,

• faults and/or breakages that are not attributable to tool anomalies,

• normal consumption of consumables.

The warranty is invalidated both in case of unauthorized tampering/replacements of tool components and in case of
use of accessories, tools or consumables different to those recommended by the manufacturer, which could even

cause injuries to the tool’s user.

Rivit S.r.l. assumes responsibilities only if the tool is originally defective, but declines all forms of responsibility if
the user fails to follow the instructions given.

#4-40 to 3/8” and M3 to M10) and male threaded inserts (from #8-32 to 5/16” and M4 to M8). The hydro-pneumatic
system and the mechanical components used inside the RIV938, when compared with other riveting tools, are more
reliable. There is less wear and tear of the components, consequently the tool will last much longer and work better.
The technical solutions adopted make the RIV938 more compact and lighter.
