GENERAL SAFETY INSTRUCTIONS FOR THE USE OF PNEUMATIC TOOLS

Use of the tool

- The tool and recommended accessories must be used in accordance with the instruction manual. The tool and accessories must be used (with the manufacturer's instructions followed) only for their intended purpose. Use of the device for any other purpose is absolutely prohibited. As a rule, the tool should be turned on before approaching the material/area of interaction.

- Maintain order at the workplace. A cluttered workplace increases the likelihood of an accident. Work in well-ventilated rooms.

- Pay attention to the surroundings. Do not expose the tool to rain. Please remember about proper lighting. Do not direct staple guns towards people and animals. Do not allow unauthorised persons to move the spiral hose, compressor or the compressor's power cord. Do not allow such people in the work area. Unauthorised persons should not be in the work area. Keep children away from the device!

- Working condition of the tool. Check the tool and the spiral hose for completeness and damage.

- Protect yourself against electric shock. When working avoid contact of body parts and of the tool with parts carrying electrical current, e.g. elements of electrical systems, heating elements, electrical devices.

- Keep the tool out of the reach of unauthorised persons. Tools not currently in use are to be stored in a dry and closed place that is inaccessible for children. Perform any maintenance operations after disconnecting the compressed air line and tank.

- Do not overload the tool. Working with the capacities given in the technical specifications is better and safer.

- Always wear appropriate work clothing. Do not wear loose clothing or jewellery when working with the device. Protective gloves and non-slip

footwear are recommended for work. Wear a hair net with long hair.

- Do not use the spiral hose for other purposes. Do not carry the tool by the spiral hose. Protect the hose from heat, oil and sharp edges.

- Take diligent care of the tool. Remember to always keep the tool clean, as this ensures effective and safe work. Observe maintenance rules. Regularly check couplings and the spiral hose, and in the event of any damage commission the repair to an authorised service centre.

- Transport. Prior to transport the tools should be properly cleaned of used materials and dried. They can only be transported after being properly protected against contamination.

ATTENTION! Always pay attention when working. Evaluate work efficiency. Proceed in a rational manner. Alcohol consumption, taking drugs and medications, as well as illness and fatigue may impair responses. In such cases do not work using the tools.

- Check the device for any malfunctions. Check the tool diligently before every use, in particular the safety elements and parts that are suspected of damage. Assess whether they fulfill the correct and intended functions. Check that moving parts are working perfectly and that they are not blocked or damaged.

All parts must be properly installed to ensure safe device operation. If you observe any signs of improper device operation, turn it off and disconnect it from the power source immediately. Defective safety components and parts should be repaired/replaced only at an authorised service centre unless stated otherwise in the instruction manual.

ATTENTION! For your own safety use only accessories and additional devices specified in the instruction manual or recommended by the manufacturer. The use of accessories and equipment other than recommended in the instruction manual or manufacturer's catalogue may entail a risk of damage to health or property.

Only fasteners listed in the manual can be used with the staple gun. Connect to a power source as described in the instruction manual

. Use the lubricants listed in the instruction manual. Staple guns marked on top with an inverted equilateral triangle can be used only with a functioning safety mechanism (also known as a "safety yoke"). Staple guns with contact actuation or continuous contact actuation marked with the symbol "Do not use on scaffolding, ladders" are not to be used for those specific purposes, for example:

- when moving from one work area to another using scaffolding, stairs, ladders or ladder-like structures, such as roof slats,

- for sealing crates or boxes,

- for fastening transport clips, e.g. on vehicles and wagons

Use spare parts designated by the manufacturer for tool maintenance.

Repairs are to be performed by qualified personnel using original spare parts, with due regard to the information given in the instruction manual. The PROFIX repair service conducts warranty and post-warranty repairs, which guarantees the highest quality of repairs and the use of original spare parts.

Stands for attaching tools to a support, for example a work table, are designed and manufactured by the table manufacturer in a manner allowing the tool to be securely fastened according to the intended use, which avoids damage, distortion or displacement.

Tools powered by compressed air may be connected to a compressed air line with a maximum allowed pressure not exceeding their capacity by more than 10%, which can be achieved through the use of a pressure regulating valve with a pressure relief valve. When using compressed air powered staple guns special care needs to be taken not to exceed the maximum allowable pressure, Staple guns powered by compressed air should be used with the lowest pressure required

for a particular work process to avoid unnecessarily high noise levels, increased wear and the resulting failures. Always use clean dry air.

Using oxygen or flammable gases to power the staple gun increases the risk of a fire or explosion. Use quick couplings to connect to the compressed air system. The seal-less coupling must be connected to the tool in such a way that no compressed air remains inside after disconnection. Some locations for use of the tool may require additional rules and regulations (e.g. work in an area at risk of explosion).

Noise

These values are characteristic values for the tools and do not represent the noise generated in the user's vertical plane.

The noise at the point of use depends, for example, on the work environment, the workpiece, the workpiece support and the number of operations.

Depending on the workplace conditions and the form of the workpiece, it may be necessary to provide individual noise suppression measures, such as placing workpieces on sound absorbing brackets, preventing vibrations of the workpiece through clamping or a cover, adjusting the air pressure to the minimum required for the operation. In special cases hearing protection equipment may be necessary.

Vibrations.

The value is tool-specific and does not reflect the effect on the hand-arm system when using the tool.

The effect on the hand-arm system when the tool is used depends, for example, on the following: grip force, contact pressure, operating direction, energy supply control, workpiece, workpiece support.

OCCUPATIONAL HEALTH AND SAFETY

1) It is the employer's responsibility to provide this instruction manual to the tool's operator!

2) Before starting work, read the manufacturer's recommendations and the technical specifications.

3) Work, inspections, as well as maintenance, should always be performed in accordance with the applicable OHS standards.

4) Wear protective goggles and ear protection when using pneumatic tools.

5) The compressor reaches a high temperature during operation. Touching it can lead to burns.

6) The air drawn by the compressor must be free from other gases and/or vapours, as they may ignite or explode in the compressor.

7) When disconnecting the quick coupling, hold the hose coupling part with your hand to avoid injury from the hose springing up.

8) Before each operation, check for proper operation of the safety mechanism and the trigger mechanism, as well as the tightness of all nuts and bolts.

9) Do not make any modifications to the tool without the manufacturer's permission.

10) Do not disassemble or deactivate any parts of the tool, such as the safety mechanism (safety yoke).

11) Do not perform any "emergency repairs" without proper tools and equipment.

12) The tool should be serviced at regular intervals in accordance with the manufacturer's instructions.

13) Avoid weakening or damaging the tool, for example by:

- embossing labels or engraving

- unauthorised modifications

- throwing or pulling along the floor

- using the device as a hammer

- applying excessive force in any form

Never direct the tool towards yourself, other persons or animals.

Hold the tool during work to avoid injuries to the head or body in the event of possible recoil resulting from disturbances in the power sup-

ply or encountering hard points in the workpiece. Never run the tool in a free space. This will prevent any danger caused by loose-fitting couplings and excessive tool tension. Disconnect the tool from the compressed air system during transport, in particular when using ladders or adopting an unusual posture when moving. Consider the conditions at the workplace. Fasteners can penetrate through thin parts or slip off their corners and edges, putting people at risk. Do not insert fasteners near the workpiece's edges. For your own safety, use protective equipment, such as hearing and eye protection. When moving the tool always hold it by the handle, never with your finger resting on the trigger.

Use only hoses with a pressure rating exceeding the maximum working pressure of the tool,

Please maintain and follow the safety guidelines. OPERATIONS AND USE OF PNEUMATIC TOOLS

Recommendations when supplying compressed air to pneumatic tools:

• The supplied air should always be clean and dry.
• Use of filter elements that capture water and solid particles is recommended.
• Before each use check the hose and couplings for their suitability for use, as well as the tightness and correctness of the connection.
• Check the power supply device (e.g. compressor, pneumatic system) before each use.
• To take full advantage of the tool's power and efficiency, use quick couplings and conduits of the right length and diameter.
• Avoid bending the hose.
• Do not use the tools for industrial purposes.
• Do not use the tools in the food industry.
• Do not use the tools in a dusty environment.

ATTENTION! Never use oxygen or other bottled gases. This could lead to an explosion.

ATTENTION! Never exceed the permissible supply pressure! Excessive pressure causes the permissible parameters of the tool to be exceeded and may result in damage to it and/or damage to the hose, which may result in an accident.

RECOMMENDATIONS FOR WORKING WITH A PNEUMATIC TOOL:

Before starting work with the pneumatic tool, make sure that it has been connected to the power source in the correct order (see Fig. 1).

(1) Compressor
(2) Filter-pressure regulator, dehydrator, optional in-line lubricator
(3)Quick coupling
(4) Spiral hose
(5) Quick coupling
(6) Pneumatic tool (example drawing)

Do not carry out repairs, adjustments or replacement of parts when working with the tool.

Protect the tools from falls and impacts, as well as contamination with, for example: mud, water, sand, etc. and maintain in accordance with the instruction manual. Also, pay attention to maintain the compressed air supply lines in good technical condition.

RECOMMENDATIONS FOR THE USE OF SPIRAL HOSES:

Hoses should be:

• firmly attached to their couplings.
• gas-tight (in case of discovering a leak, immediately turn off the compressed air supply),
• blow through with warm air,

- connected to power sources equipped with oil removal devices and condensate pots.

- protected against mechanical damage and the influence of corrosive substances (acids, alkalis), oily substances and greases.

Use reinforced hoses in areas carrying a risk of mechanical damage. If the hose is found to have come into contact with corrosive materials, wash the hose with plenty of water and check for tightness, discoloration and/or deformation, as well as whether the hardness of the outer surface of the hose has changed. Do not use a damaged hose!

A hose contaminated from the outside with greases or oils should be carefully cleaned with dry cotton oakum.

Using a hose that is damaged and/or contaminated, as specified above, carries the risk of an accident at work.

Connect and disconnect the hose from the tool only when the air valve is closed. Do not cut off the air supply by bending the hoses!

After connecting the hose to a power source, first purge it, taking the necessary precautions to remove the dust accumulated inside and then connect the pneumatic tool.

The hoses should not touch or be in the vicinity of live electrical conductors.

DESCRIPTION OF OPERATIONS AND USE

The pneumatic staple gun is a practical tool used to connect elements to each other, e.g. when adding finishing materials to furniture, fixing insulation films in construction, in upholstery work, finishing work, etc.

The device is to be powered by compressed air with a maximum pressure of 8 bar. The staples are accelerated to a high speed in the device, which in combination with an appropriate construction of the staple gun results in effective joining of elements. At the same time, it requires the user to proceed carefully. Use quick couplings of an appropriate size and spiral hoses of a correct diameter - this will allow the tool's parameters to be used fully, including its efficiency.

OPERATIONS AND USE

Any activities aimed at getting familiar with the device and related to opening the magazine, loading staples, removing any staple jams in the device, etc. absolutely need to be performed with the air supply switched off - the hose must be disconnected from the staple gun.

The activities described below reference the drawing on page 2 of this instruction manual.

1. Press the magazine release button (7) while pulling on the magazine latch (8) in direction "0" shown in Figure 2

This will move the staple pusher (10) away from the staple guide (11) and make space for the staples in the magazine.

1. Insert a pack of staples (only one type - do not mix staples of different sizes) into the magazine with the sharp parts of the staples directed downwards.

2. Close the magazine by moving the latch (8) in direction "Z" until the magazine closes (with a clearly audible click).

3. After the magazine is closed, the staple pusher (10) and the guide (11) form a slot through which accelerated staples are ejected.

4. Add a few drops (2-3) of oil (VG32) into the air inlet coupling (6) of pneumatic devices. On average, 2-3 drops of oil are assumed to be the amount required for all-day work.

It is absolutely recommended to use filters with a water trap in the compressed air supply system - water in the supply may cause corrosion of the stapler.

The use of an in-line lubricator in the compressed air supply system is recommended, as it removes the need to manually add oil.

1. Connect the hose and adjust the pressure on the compressor to a maximum of 8 bar.

NOTE: Adjusting staple driving power (depth of the staple penetration in the material) is possible by adjusting the air pressure.

Therefore, it is recommended to perform a test before fastening the target elements, changing the pressure in increments of 0.5 bar, using the device in the manner described above.

1. For the device to start, it is necessary for the trigger (3) and the safety (5) to work simultaneously - see Fig. 2
2. Move the stapler towards the work surface (e.g. the board into which the staple is to be driven) and press it lightly to push the safety. Press the trigger.

The staple hits the work surface.

The driving of subsequent staples is possible by individual presses of the trigger, if the safety remains pushed down.

Note: Never press the safety in with your fingers – this may cause an accident!

1. The upper part of the head features openings for ejection of air (excess air in a given cycle) located on a rotary knob. This allows you to set the air direction, so that it does not interfere with work.

REMOVING JAMMED STAPLES

If staples become blocked, turn off the compressor and disconnect the device from the compressed air hose (remaining air may cause an accidental start-up of

the stapler).

Then remove the staples from the magazine. Remove the screws "S" shown in drawing No. 4 and

remove the fuse cover. This will move the staple guide and provides access to jammed staples.

STORAGE, MAINTENANCE, REPAIR

In general, the stapler does not require special maintenance activities. Keep the stapler stored in a place that is not accessible to children, clean, protected from moisture and dust. Storage conditions should secure against possible mechanical damage and atmospheric factors. If any irregularities in the operation of the stapler are found, the magazine should be checked and cleaned with compressed air. In case of further problems, commission a repair with a PROFIX service centre. The PROFIX repair service conducts warranty and post-warranty repairs of its power tools, which guarantees the highest quality of repairs and the use of original spare parts.

TRANSPORT

Transport and store the stapler in a package that protects it against moisture, dust ingress and mechanical damage.
