Read the operating instructions and pay particular attention guide- lines and technical descriptions. If there is no other information available, only use the tool for the fastening of wood to wood or material with the same or less hard- ness.

Tackers must comply with ES 792-13 concerning ”Hand-held non-electric power tools -Safety requirements- Part 13: Fastener driving tools”. This standard stipulates that: s tackers must only be employed to drive in fasteners listed in the operating instructions accompanying the tool (see TECHNICAL SPECIFICATIONS). The tacker as well as the fasteners described in the operating instructions are to be considered as a system in compliance with the safety specifications. s rapid action hose couplings must be employed to connect the tool to the compressed air source and the male connector must be affixed to the tool in such a manner that no air remains in the tool after the line has been disconnected. s oxygen and other flammable gases must not be used as an energy source for pneumatic tackers. s tackers must only be connected to air lines in which the pres- sure does not exceed the maximum operating pressure of the tool by mor e than 10 %. If the pressure is higher, a pressure control valve (pressure limiter) equipped with a downstream pressure relief valve must be installed in the compressed air line. s only those replacement pieces authorized for use by the manu- facturer or his agent may be employed in the maintenance of the tool. s maintenance work must be performed by authorized service centers or other competent repair professionals in accordance with the specifications printed in the operating instructions.

ENGLISH20 Note: A competent repair professional is defined as a person who possesses sufficient knowledge of tackers due to his professional training and experience and who has sufficient knowledge of the relevant government work safety reg- ulations, accident prevention regulations, guidelines and generally recognised technological directives (e. g. CEN or CENELEC Standards ) to permit him to evaluate whether the tacker is safe for operation. ∞ mounting devices whose purpose is to fix the tacker to a base, e. g. a work table, must be designed by their manufacturers to allow the tacker to be affixed in such a way that it can be safely operated, e.g. preventing damage, twisting or shifting. The use of the tacker in particular areas of application may require compliance with additional regulations and directives (e. g. work areas where danger of explosion exists).

1.2 Work Safety Guidelines

Danger! At close distances, the stapler is similar to a firearm. Therefore, never point a stapler that is ready for operation directly at yourself, other persons or animals. Danger! The stapler can recoil and cause injury to the operator. When working with the stapler, hold it in such a manner that your head and body cannot be injured in case it recoils. Danger! Hands and other parts of the body in the vicinity of the muzzle can be injured. Hold your hands and other parts of your body away from the area of the muzzle when working. Danger! Triggering the stapler while it is pointed into the air can cause danger due to flying fasteners and can cause the device to overload. Never trigger the stapler when pointing it into the air! Danger! Fasteners can slide off and injure the operator. Never try to set a second fastener on the back or head of a fastener already inserted, this can cause damage. ENGLISH21 Danger! The stapler can accidentally be triggered during trans- port. During transport, the stapler must be disconnected from the source of pneumatic pressure, especially if you are using lad- ders or are working in unaccustomed positions. Danger! The stapler can accidentally be triggered when being carried. Always carry the stapler by the handle at the workplace and never with your finger on the trigger. Danger! Fasteners can penetrate thin work materials or can slide off when working on ceilings or edges of work materials, thus posing a danger to per- sonal safety. Therefore, you should always take the conditions of the individual workplace into consideration. Danger! Fasteners can fly through a room or materials can split due to the stapling process. The loudness at the place of use can exceed the permissible values. Always wear protective gear such as eye protection and hearing protection. The same also applies to other persons nearby.

1.3 Tacker Safety Guidelines

Danger! A defective or improperly functioning stapler can result in danger to yourself and others. Each time before use, verify that safety features and the trigger mechanism are working correctly and that all screws and nuts are firmly fastened. Do not make any unauthorized changes to the tacker. Do not disassemble the tacker or block the operation of any part, (e. g. do not disarm the trigger safety). Danger! Improper or inadequate maintenance can result in danger to yourself and others. Do not perform any ”makeshift” repairs using inappropriate material. The upkeep of the tacker must be performed regularly by authorized service personnel. In order to avoid damaging or weakening the tacker, do not: – engrave or strike the tool; – make modifications not approved by manufacturer; – drive fasteners in hard metal, e. g. steel; – drop or slide along the floor; – use as a hammer; – misuse the tool in any way. PREBENA-Pneumatic staplers and nailers ENGLISH22

The noise output of the tacker was measured in accordance with DIN EN 12549 ”Noise test code for fastener driving tools” (see TECHNICAL SPECIFICATIONS). The values are a measure of the noise output of the tool itself and are not an indication of noise in the workplace. The workplace noise levels will depend upon, for example, the surroundings, the work materi- al, the work surface, the number of fasteners being driven etc. According to the workplace conditions and the work material, measures may have to be taken to reduce noise levels for individuals by laying the work mate- rial on a sound-absorbing base, by reducing vibrations of the work material by securing it in a vice or covering it up, by setting the operating pressure to the lowest position possible for the task being performed. Personal hearing pro- tection should be worn.

The vibration measurements for the tacker were carried out in accordance with ISO 8662-11 ”Hand-held portable power tools- Measurments of vibrations at the handle - Part 11: fastener driving tools”. The value is a measure of the vibration produced by the tool itself and does not represent the eect on the hand or arm when the tacker is in use. The eect on the hand and arm depends upon how strong the machine is gripped or pushed against the work material, the angle the tool is held at, the pressure setting, the work surface and the base being worked on.

1.6 Triggering Mechanismus

The tacker is activated by pulling the trigger with your nger. In addition, certain tackers must be equipped with trigger safeties that prevent a fastener from being driven in if the muzzle is not placed against the work surface. These tackers are identied with an upside down triangle ( ) and cannot be used without the trig- ger safety in place. E NG L IS H23

1.7 Triggering Systems

Depending upon the use, the tackers can be equipped with differ- ent triggering systems. Single-Fire Trigger: In this triggering procedure, the trigger must be activated once each time a fastener is ejected. The trigger must be fully released before a new fastener can be driven in. Single-Fire Trigger with Trigger Safety (preferred method of use): In this triggering procedure, the trigger and the trigger safety must be activated before a fastener can be ejected. This means that when the trigger is pulled, a fasten- er is ejected only when the tacker muzzle is pushed against the point where the fastener is to be driven. Further fasteners can only be driven after the trigger has been fully released. Single-Fire Trigger with Safety Sequence: In this triggering procedure, the trigger and the trigger safety must be activated before a fastener can be eject- ed. This means that when the trigger is pulled, a fastener is ejected only after the tacker muzzle has been pushed against the point where the fastener is to be driven. Further fasteners can only be driven after the trigger and the trigger safety have been fully released. Contact Trigger (for restricted uses): In this triggering proce- dure, the trigger and the trigger safety must be activated before a fastener can be ejected, but the order in which this takes place is not important. To drive in further fasteners, all you have to do is release the trigger safety while keeping the trigger held down, or vice versa. The contact trigger may not be used: – when moving from one work point to the next for example over stairs, ladders or scaffolding. – when sealing boxes or crates. – when attaching safeties for transport. Rapid-fire Trigger: In this triggering procedure, fasteners are ejected as long as the trigger is held down. Rapid-fire Trigger with Trigger Safety (for restricted uses): In this triggering procedure, the trigger and the trigger safety must be activated before a fastener can be ejected. This means that when the trigger is pulled, a fastener is ejected only after the tacker muzzle has been pushed against the point where the fastener is to be driven, but the tacker fires contin- PREBENA-Pneumatic staplers and nailers ENGLISH24 uously until the trigger is released. The rapid-fire trigger may not be used: – when moving from one work point to the next for example over stairs, ladders or scaffolding. – when sealing boxes or crates. – when attaching safeties for transport. Pneumatic staplers that are equiped with contact trigger (for restricted use) or Rapid fire trigger with trigger safety and labelled with the symbol “do not use on scaffoldings and ladders” are not allowed to be used for above mentioned applications. For optimal tacker operation, dry, filtered and oiled compressed air is required in sufficient quantities. If the pressure in the air lines is higher than the maximal admissi- ble operating pressure of the tacker, a pressure control valve (pressure limiter) equipped with a downstream pressure relief valve must be installed in the inlet line to the tacker. Note: When compressed air is generated using a compressor, the natural humidity in the air condenses and collects as conden- sation in the pressure chamber and tubing. This conden-sation is removed from the system using water collectors. The collectors must be checked daily and emptied if necessary, otherwise rust may form in the pneumatic lines and the tacker and result in tool wear. The compressors must meet all requirements regarding the pressure and suc- tion capacity (volume flow) for the envisioned use. Excess strain on the com- pressor or capacities that are too low in function of the tubing lengths (tubes and hoses) will lead to loss of pressure. Permanently laid air lines must have an interior diameter of at least 19 mm. In the case of longer air lines or multiple users, the lines must be strengthened correspondingly. The air lines should be sloped (highest point towards the compressor). Install easily accessible water collectors at the lowest points. All user air outlets must be built on to the top side of the air lines. Compressed air outlets that are planned for use with tackers should be equipped with compressed air maintenance units (i. e. filter, water collectors, oiler). The oilers must be checked daily and, if necessary, be filled with the required oil (see TE CHNICAL SPE CIFICATIONS). ENGLISH

2. Compressed Air System25

For hose lengths of over 10 m, it cannot be guaranteed that a sufficient supply of lubricant will reach the tacker. For this reason, we recommend oiling the tool directly through the air input with 2-5 drops of the recommended oil daily before use (see TECHNICAL SPECIFICATIONS) or to build an oiler directly onto the tool. Make sure that the pressure in the compressed air lines does not exceed the maximal admissible operating pressure of the tacker. First set the air pressure to the lowest working pressure (see TECHNICAL SPECIFICATIONS). Empty the magazine so that no fasteners are ejected during the next step, in case parts inside the tacker did not return to the initial position due to repairs, maintenance or trans- port. Connect the tacker to the compressed air source using a compressed air hose equipped with a rapid action coupling. Verify that the tacker is in optimal working condition by settinq the muzzle against a piece of wood and pulling the trigger once or twice.

PREBENA-Pneumatic staplers and nailers ENGLISH26 Only fasteners listed in the TECHNICAL SPECIFICATIONS and on the model Familarise yourself with the magazine system that the tacker is equipped with (see TECHNICAL SPECIFICATIONS). With bottom-loading systems, push down the safety catch and pull back the lower slide bar. Hold the tool at an upwards angle and insert the bars of sta- PREBENA-Pneumatic staplers and nailers

4. Loading the magazine27

Push the lower slide bar back into place until the safety catch clicks into place. There are two types of top-loading systems. Either the upper part of the mag- azine is unlocked and then pulled back until it catches or the fastener feed bar is pulled back until it catches. Point the tool towards the ground. Staple bars are inserted on top of the guiding rails and nail strips are inserted between them. Release the feed bar and snug up to the bar or strip by hand, or push the mag- azine forwards until it locks into place. ENGLISH28 With side-loading systems (A), release the safety catch and pull the side slide bar back. Point the tool at an angle towards the ground and insert the nail strips so that the head slips into the corresponding groove and the tip lies as close to the magazine bottom as possible. With the coil nailer system (B), push down the hook and open the ap. Open the magazine lid. Verify that the nail plate is properly adjust- ed for the nail length being used. To adjust the plate, push lightly on the middle knob and turn counter-clockwise to raise it. Repeat if necessary. To lower the plate, push down the middle knob lightly and turn clockwise. Repeat if necessary. Insert the roll in the magazine and pull the rst nail into the front of the tool with the heads in the head guide grooves and the two wires in their respective grooves. Secure the rst nail between the teeth of the feed mechanism. Close the magazine lid and check to see if the plastic tooth is pushing into the side wall of the feed mechanism. Make sure that the ap is locked into position! If you do not check for this, the nailer could jam or the lid could open when work- ing in vertical positions or above your head. The trigger must never be activated during loading and the muzzle of the tool must never be pointed at yourself or at another person. PREBENA-Pneumatic staplers and nailers (A) (B)29 Please pay special attention to Section 1 – Special Remarks – of these operating instructions. Once you have verified that the tool is in optimal operating order, set the muzzle against the work surface and activate the trigger.

Warning: When driving in fasteners, especially in hard wood or

when using longer fasteners, the tool may recoil. In the case of tackers with contact triggers (see 1.7), unintentionally setting the tacker against the work surface may cause it to eject another fas- tener when you do not want this. For this reason, always hold the tacker well away from the work surface and set it on the surface only when you wish to drive another fastener. Verify that the fastener was driven in according to your specifications. If the fastener is sticking out, increase the air pressure in 0. 5 bar increments (do not exceed maximum pressure) until the proper depth is obtained. If the fastener was driven in too far, reduce the air pressure in 0. 5 bar incre- ments until the fastener is driven in satisfactorily. In all cases, try to work with the lowest required pressure. This has three essen- tial advantages for you:

2. Noise levels are kept to a minimum.

3. Tool wear is kept to a minimum.

Avoid pulling the trigger when the magazine is empty. Disconnect the tool immediately from the air supply if it is defective or not in optimal working order and bring it to a competent repair person. Disconnect the tacker from the air supply and if possible empty the magazine during longer work breaks and at the end of the day. Protect the air connections on the tacker and the air hoses from dirt. If sawdust, shavings, sand etc. get into the tacker, this can lead to breaks in the seal and will eventually damage the tacker and the hook-ups. ENGLISH
