2. SPECIFICATIONS
2.1 INTENT OF USE
The 74290 Tool is designed to convert round holes in to hexagonal holes. The latter are produced by means of a drill. Then
the tool, equipped with punch and reference die, is to be inserted into the hole, where it removes other material in order to
obtain a hexagon hole, ready to receive threaded hexserts.
In this way it is possible to easily and rapidly install threaded inserts which, owing to the hexagon prole, guarantee the on-
rotation of the joint, with evident advantages regarding the production process and the oered performances, compared to
round threaded inserts or other competitor technologies (nuts, welded nuts, etc...).
The use of this tool for threaded inserts enlarges the range of application (up to now it was restricted to the employment of
pre punched sheets) for box type design pieces, low volume series production and in situ applications.
For further details regarding the preparation of the hole in relation to the type of material and the thickness, see page 12.
DO NOT use under wet conditions or in the presence of ammable liquids or gases.

3. PUTTING IN SERVICE
IMPORTANT - READ THE SAFETY RULES ON PAGE 4 - 6 CAREFULLY BEFORE PUTTING INTO SERVICE.
• Select relevant size nose equipment and install.
• Connect the placing tool to the air supply. Test pull and return cycles by depressing and releasing the trigger 40.
• Set the tool for desired stroke/pressure.
CAUTION: Correct supply pressure is important for proper function of the installation tool. Personal injury or damage
to equipment may occur without correct pressures. The supply pressure must not exceed that listed in the placing tool
specication.
3.1 PRELIMINARY OPERATIONS
Every day, before using the tool, carry out the operations described in section “LUBRICATION”.
Before connecting the tool to the air supply, blow compressed air through the feed pipe, in order to eliminate any trace of
condensation water or foreign matter.
LUBRICATION: Prior to connecting the air hoses, pour a small quantity of light hydraulic oil into the air admission tting
3.2 AIR SUPPLY
All tools are operated with compressed air at an optimum pressure of 5 and 7 Bar. We recommend the use of pressure
regulators and automatic oiling/ltering systems on the main air supply. These should be tted within 3 metres of the tool
(see diagram below) to ensure maximum tool life and minimum tool maintenance.
Air supply hoses should have a minimum working eective pressure rating of 150% of the maximum pressure produced
in the system or 10 bar, whichever is the highest. Air hoses should be oil resistant, have an abrasion resistant exterior and
should be armoured where operating conditions may result in hoses being damaged. All air hoses MUST have a minimum
bore diameter of 6.4 millimetres or 1/4 inch.
We recommend to operate the tool at the minimum pressure necessary to obtain the requested hole, to consume less air
and the maximum tool life is ensured.
