Description – purpose of use

• The Fortum® 4770664 Professional Rivet Drill Adapter is designed to be clamped in the chuck head of a cordle- ss drill, electric drill or pneumatic drill for the installation of size M3, M4, M5, M6, M8, M10, M12 rivet nuts , made from alumi-nium, steel and stainless steel. Pulling the rivet nut will create a strong material joint.

• Thanks to its integrated handle, it is possible to use  the rivet drill adapter for rivet nuts of size of up to M12 and, at the same time, this handle increases the comfort during the installation of rivet nuts of smaller dimensions since the handle helps to better cope with the effects of the torsion force that is generated when rivet nuts are pulled.

• The rivet drill adapter fully replaces a self-powered riveter and since a drill is a standard piece of workshop or household equipment, one can have the rivet drill adapter as an supplementary drill accessory at a lower purchase price than a dedicated electric or pneumatic riveter.

DRILL REQUIREMENTS
Requirements for max. torque values relative  to the size and material of the rivet nut.

ATTENTION

• Table 1 presents the maximum permissible tightening torque values for pulling rivet nuts with respect to their material and size. Using a higher torque frequently results in the thread of the rivet mandrel being torn out of the rivet nut (particularly on small rivet nuts), which damages the tread of the rivet mandrel.
• In the column „Recommended minimum drill torque“ there are torque values that the drill should be able to achieve, representing torque values that are used for the rivet nut material of the specified size, but express the recommended „drill power“ such that when the maximum permitted torque is set the drill motor is not overloaded.

Option to run the drill at a very low rotation speed of < 20 rpm.
WARNING

• A low rotation speed is very important for work safety. A low rotation speed enables the user to better handle the torsion forces, which are significant TORQUES particularly when pulling rivet nuts of larger diameters. If necessary also set more suitable conditions for the installation of rivet nuts, e.g. by adjusting the position of the drill so that the rivet nut is on the axis of the centre of the pre-drilled hole, etc. When the rivet nut is pulled, the handle of the adapter may be violently jolted out of the hand if not firmly held in position, which may lead to an injury.

Option to set max. permitted torque with   respect to the material and size of the rivet nut.
WARNING

• For the installation of a rivet nut, it is essential to have sufficient torque in order to pull the rivet nut, but it is also necessary to ensure that the thread of the rivet mandrel thread is not torn out of the rivet nut, which damages the thread of the rivet mandrel. Tearing out of the rivet mandrel thread from the rivet nut occurs easily on smaller rivet nuts, particularly of sizes M3 and M4. To set the correct torque with respect to the material and the size of the rivet nut, it is necessary to perform practical tests with respect to the maximum permitted tightening torque values specified in table 1. Tearing out of the rivet mandrel from the thread of the rivet nut is not the fault of the rivet drill adapter but rather is caused by excessive torque of the drill. In the event that the thread of the rivet mandrel is torn out even when the lowest possible torque is set on the drill, it is necessary to select a drill with a lower torque, otherwise the rivet mandrel thread will become worn out.
• With respect to the above-described fact, the most preferable type of drill for use with the rivet drill adapter is a cordless drill that enables the optimal torque to be set based on the performance of practical tests and enables operation at very low rotation speeds, which is important for the safe use of the rivet drill adapter.

ATTENTION
When a cordless drill is used for pulling the rivet nut, its battery must be well charged, which is important par-ticularly for larger rivet nuts. Higher current is drawn under load and if the battery is not sufficiently charged or has a low capacity in mAh, which may be the result of wear, it may not sufficiently meet the consumption of current requirements, and the drill, despite having a sufficiently large torque may not necessarily provide the required performance.
Li-ion batteries have integrated electronic protection against complete discharge, which damages them. This protection manifest itself by the battery suddenly ceasing to supply electrical current and the motor of the cordless drill suddenly stopping. After a sufficiently long break the supply of electrical current is renewed, however, it will again stop suddenly when placed under load, which may manifest itself while a rivet nut is being pulled.

ATTENTION

• The torque value specified in the technical specifications of the drill may not be precise and may be determined by means of several possible methodologies with varying uncertainty, and thus for the correct installation of a rivet nut it is essential to first perform a practical test to verify that the torque of the drill is sufficient.

IMPORTANT INFORMATION ABOUT DRILL SETTINGS

• Always set the lowest speed level on the drill, since it  applies that torque is greater at lower speeds, other-wise the tightening torque of the drill may not be sufficient.
• In the event that the drill has a torque adjustment setting and the tightening torque is insufficient even when set to the highest possible tightening torque, set it to drill mode (symbol of a drill bit on the torque adjustment dial) – this setting option is standard on cordless drills. In the event that the tightening torque is insufficient even when the drill mode is set, it is necessary to select a drill with a higher torque.

WARNING

• It is forbidden to use the rivet drill adapter with otherwise damage will result that is not covered   by free warranty repairs.

Replacement of the rivet mandrel with nosepiece with respect to the size

of the rivet nut

SIGNIFICANCE OF THE POSITION OF THE „O“ RING IN THE HANDLE
ATTENTION

• The position of the „O“ ring in the handle is used to set two different functions of the rivet drill adapter that are necessary for installing rivet nuts.

• When the „O“ ring is extended on the edge of the handle (fig. 1A), the rivet mandrel turns together with the chuck head of the drill, which is necessary for screwing in the rivet nut on to the rivet mandrel of the adapter to install the nut and then for unscrewing an already pulled rivet nut from the mandrel of the rivet drill adapter.

• When the „O“ ring is inserted in the handle (fig. 1B), the rivet mandrel slides in or out depending on the rotation direction of the chuck head of the drill, which is necessary namely for pulling the rivet nut that is inserted in a pre-drilled hole.

ATTENTION
The size of the rivet mandrel needs to be selected according to the size of the rivet nut. The size and length of the rivet nut must be selected to respect the diameter and depth of the pre-drilled hole, otherwise the material being joined will not be joined properly. The size of the rivet nut must then correspond to the size marked on the rivet mandrel and on the rivet nosepiece in the form, e.g. M5, M6, etc.

ATTENTION
The rivet drill adapter may only be used with rivet mandrels and nosepieces that are supplied with this rivet drill adapter model. Using rivet mandrels and nosepieces intended for other riveting devices is not permitted even when it is possible to screw them into this adapter as this could result in damage to the rivet drill adapter.
The replacement of rivet mandrels is described in individual steps of the procedure in figures 1C to 1H.

• Retract the „O“ ring on the handle of the rivet drill adapter into the handle as shown in fig. 1B.
• Using an assembly wrench, screw out the rivet nose-piece as shown in fig. 1C.
• Screw out the flange as shown in fig. 1D.
• Take the spring off the rivet mandrel as shown in fig. 1E.
• Using an assembly wrench, screw out the rivet mandrel as shown in fig. 1C.
• Then screw the rivet mandrel with the marked size corresponding to the size of the rivet nut into the thread (fig. 1G).

Clamping the rivet drill adapter into the chuck head of a drill (fig. 2)

• Retract the „O“ ring on the handle of the rivet drill adapter into the handle as shown in fig. 1B.
• Open the chuck of the drill and insert the hexagonal shank of the rivet drill adapter fully into the chuck.
• Then firmly clamp the chuck of the drill to properly secure the rivet drill adapter in the drill.

Installing rivet nuts

ATTENTION

• To set the optimal torque and to become acquainted with  the methodology of work with the rivet drill adapter, first perform practical tests on a piece of sample material. Initially set a lower torque, which can be increased if insufficient. Setting a torque that is too high will result in the thread of the rivet mandrel being torn out of the rivet nut, which likewise damages the thread of the rivet mandrel and causes wear to the internal parts of the adapter that is not covered by free warranty repairs/replacement of the rivet drill adapter. In the event that the thread of the rivet mandrel is torn out even when the lowest possible torque is set on the drill, it is necessary to select a drill with a lower torque, otherwise the rivet mandrel thread will become worn out.

WARNING

• For safe work, it is necessary to work at rotation speeds of < 20 rpm.
• Set the lowest speed level on the drill and very gently control the speed by slightly pulling on the trigger.
• Pull the „O“ ring on the handle of the rivet drill adapter to the edge of the handle, see fig. 1A or fig. 3A.
• Set the lowest rotation speed on the drill and set the rotation direction of the chuck head to right.
• In one hand, hold the rivet nut pointing in the direction shown in fig. 3A and at a low rotation speed screw the rivet mandrel into the rivet nut.

ATTENTION

• The rivet nut must be screwed on to the rivet mandrel along its entire thread, however without being tightened fully, the force of holding the rivet nut between the fingers is sufficient for screwing on to the rivet mandrel of the adapter.

ATTENTION

• The rivet nut must be screwed on to the rivet mandrel in the orientation shown in fig. 3A, otherwise it will not be possible to screw it on to the rivet mandrel.

• Then eliminate the gap between the screwed on rivet nut on the mandrel and the nosepiece while turning the chuck head to the right with the „O“ ring on the edge of the handle, see fig. 3B.
  During this procedure, the rivet mandrel (axis of the adapter) will rotate, but also at the same time the mandrel will be gradually inserted into the rivet drill adapter, by means of which the gap between the rivet nut and the nosepiece is eliminated as shown in fig. 3B. Allow the chuck head to rotate until the rivet nut is completely naturally seated on the nosepiece as shown in fig. 3B. Then firmly tighten all flanges and threaded elements of the rivet drill adapter.
  The gap can also be eliminated by the chuck head rotating to the right with the „O“ ring retracted in the handle, whereby the mandrel is gradually inserted into the rivet drill adapter without turning the axis of the adapter, however, once the rivet nut is seated on the nosepiece, the rivet nut will immediately start being pulled with a generated reactive recoil and this procedure requires a certain degree of experience and thus it is recommended to start with the first described method.

• Retract the „O“ ring on the handle of the rivet drill adapter into the handle and insert the rivet nut screwed on the rivet mandrel into the pre-drilled hole on the axis passing though the centre of the predrilled hole (fig. 3C).

ATTENTION

• The joined materials must be safely secured prior to installing rivet nuts.

Firmly grasp the handle of the rivet drill adapter and the handle of the drill and assume a firm stable posture, whilst for pulling nuts the rivet drill adapter must be placed in line with the axis passing through the centre of the pre-drilled hole. By gently pulling the trigger of the drill (speed < 20 rpm) whilst the chuck head rotates to the right the rivet nut will be pulled, see fig. 3D. The pulling of the rivet nut must achieve a firm joining of materials as shown in fig. 3D. In the event that while the rivet nut is being pulled, the thread of the rivet mandrel is torn out from the rivet nut, it is necessary to set a lower torque so that this does not happen.

WARNING

• When the rivet nut is pulled a force acts on the handle of the rivet drill adapter with the tendency to deflect the handle to the side. In the event that the handle is not held firmly and the rotation speed of < 20 rpm is not used, the user may be injured by the handle being jolted out.
• Then change the turning direction of the chuck  head to the left with the „O“ ring retracted in the handle (fig. 3E/1), whereby the rivet mandrel slides out of the rivet adapter and a gap is created between the installed rivet nut and the rivet nosepiece of the adapter, which subsequently enables the rivet man-drel to be screwed out of the rivet nut according to the procedure provided below. Then extend the „O“ ring to the edge of the handle (fig. 3E/2) and by tur-ning the chuck head to the left, screw out the rivet mandrel from the installed rivet nut (fig. 3E).

Supplementary safety instructions

• Prior to using the rivet drill adapter, carefully read the safety instructions in the user‘s manual for the drill, which contains important safety instructions for working with the drill.
• Keep hands and all body parts in a safe place at a sufficient distance from the work area.
• Make sure that there is no loosely hanging clothing, chains, long hair, gloves, etc. in the vicinity of the work area since they could be caught by the rivet nut.
