8) INSTALLATION, ASSEMBLY INSTRUCTIONS
During the installation of the accessory please use adequate Personal Protective Equipment: gloves,
safety shoes, helmet, etc.
Unscrew the jaws, so that the maximum available opening can be obtained, and connect them to the
parts to pull.
Connect one rope or one part for each terminal.
After the connection has been completed, move the bolt locking nut to the jaw wall; avoid
overtightening, to prevent flexure towards the inner part of the jaw.
Exert tensile stress through the main body, making sure that, after the operating condition has been
reached, the terminals have been inserted into the body at least throughout the length of its thread.
While exerting tensile stress, make sure that the turnbuckle can freely move and position itself; hence no
forcing or interference should occur, to prevent any lateral force components from being produced.
Tensile stress should be checked after a short period, to make up for any system adjustments.
Particular attention is required while tensioning, to prevent the working force limit (WFL, see Table
“A”) from being exceeded, which would result in permanent deformation, especially if any levers or
mechanical means are used.
If the turnbuckle is subjected to the danger of loosening, for example because of the presence of
vibrations, it’s recommended to use a locking nut, to be screwed on the terminals before their mounting
on the turnbuckle body.
NOTE: for each turnbuckle it’s necessary to mount one nut with right-hand thread and one with left-
hand thread.
9) USING ACCESSORY – GRIP AND HANDLING
The turnbuckle is designed to be used in static situations; periodically check tensile stress, the state of
preservation of the parts and their connection, according to the Table “Maintenance jobs and
inspections”.
10) NONPERMISSIBLE USE
Using the accessory for any purposes other than the purposes it has been designed for, using it under
extremely dangerous conditions and performing poor maintenance may pose a severe hazard to the
safety of the people being exposed and cause severe damage to the working environment, while
affecting the actual serviceability and safety of the product. The precautions mentioned below, which,
obviously enough, cannot cover the whole spectrum of potential “misuses” of the accessory, should be
“reasonably” deemed to be the most common steps to take. Therefore:
• DO NOT connect the accessory to any apparatus which does not match its specifications
in terms of size, temperature, hook-up point and shape;
• DO NOT use the accessory for direct lifting purposes;
• DO NOT stretch any apparatus that may change its static configuration, centre of gravity
or chemical and physical state;
• DO NOT use the accessory to lift or carry people or animals.
• DO NOT use the accessory to pull restrained loads;
• DO NOT work in areas where any explosion/spark-proof parts are expected to be used or
in the presence of big magnetic fields;
• DO NOT weld any metal parts to the accessory; do not use any filling welds; do not use
the accessory as mass for any welder.
11) FITNESS FOR USE
The accessory was subjected to spot check in order to test serviceability and performance at the
manufacturer’s. The certificate supplied with it states that the tests were passed. However, before
starting working, the user should test the installed accessory for serviceability and performance, to prove
the entire system is fit for use.
