Technical Data

General Safety Conditions

⚠️ WARNING! During operation of a pneumatic tool, it is recommended to always observe the basic safety regulations including those mentioned below, in order to diminish the risk of fire, electric shock, and injury.

Before operation of the tool can be commenced, the whole manual must be read and kept.

ATTENTION! Read all the instructions mentioned below. If they are not observed, there is a risk of electric shock, fire, or injury. The notion of „pneumatic tool” that is used in the instructions refers to all tools that are powered with a stream of compressed air at appropriate pressure.

Observe the Following Instructions

Workplace

The place of work must be well lit and kept clean. Disorder and weak light may be causes of accidents. Do not use pneumatic tools where there is a risk of explosion, in an atmosphere that contains inflammable liquids, gases, or fumes. Prevent access of children and unauthorized persons to the place of work. Loss of concentration may cause loss of control of the tool.

Safety

The connector of the pneumatic tool must fit the socket of the air supply duct. Do not modify the connector or the power supply socket. All ducts, connectors, and sockets must be clean, undamaged, in good technical state, and suitable to be used with pneumatic tools. Pneumatic tools are not insulated from contact with electric energy sources, and therefore any contact with grounded surfaces must be avoided (pipes, heaters, and refrigerators). Grounding of the body increases the risk of electric shock. Do not expose pneumatic tools to atmospheric precipitation or humidity. Water and humidity inside the tool increase the risk of damage and injury. Do not overload the air supply duct. Do not use the duct to carry, connect, or disconnect the connector from the compressed air tank. Avoid contact of the power supply cord with heat sources, oils, sharp edges, or mobile elements. Do not power the pneumatic tool with oxygen, inflammable, or toxic gases. Use only filtered and “lubricated” compressed air whose pressure may be regulated. Make sure that the processed object is properly fixed and will not move during processing.

Personal Safety

Work in good physical and psychological condition. Pay attention to what you are actually doing. Do not work if you are tired or under the influence of medicines or alcohol. Even a moment of distraction during work may lead to serious injuries. Use personal protection. Wear protective goggles. Using personal protections like anti-dust masks, protective shoes, helmets, or hearing protectors reduces the risk of serious injuries. While operating a pneumatic tool, wear protective gloves in order to protect yourself from mechanic injuries and thermal influence of the tool. Avoid starting the tool by chance. Make sure the switch is in the position „OFF” before the tool is connected to the compressed air tank. Keeping a finger on the switch or connecting the tool when the switch is in the position “ON” may cause serious injuries. Before the pneumatic tool is connected, remove all wrenches and other tools that were used for adjustments. A wrench left on mobile parts of the tool may cause serious injuries. Keep balance. During the whole period of work, maintain an appropriate position. This will facilitate the operation of the pneumatic tool in the case of unpredictable situations during work. Use protective clothes. Do not wear loose clothes or jewellery. Keep hair, clothes, and gloves away from the mobile parts of the tool. Loose clothes, jewellery, or long hair may get caught in the mobile parts of the tool. Use dust removing systems and dust containers if the tool is equipped with them. Connect them correctly. A dust removing system diminishes the risk of serious injuries. The feeding duct is under pressure, which may cause its dynamic movements and serious injuries. Stored compressed air is a hazard.

Operating the Pneumatic Tool

Do not use the tool in a manner that does not correspond to its purpose. Do not overload the pneumatic tool. Use a proper tool for a given job. Do not exceed the maximum acceptable working pressure. A proper choice of tool for a given job will guarantee more efficient and safer operation. Before the tool is regulated, accessories are changed, or the tool is stored, the feeding duct must be disconnected. This protects the pneumatic tool from casual switching on. Store tools away from children. Do not permit operation of the tool by persons who have not been trained in its operation. The tool must be properly maintained. Check the tool for lack of adjustment and play of mobile parts. Check if any element of the tool is damaged. In case any defects are detected, they must be repaired before the pneumatic tool may be used. Many accidents are caused by incorrect maintenance of tools. Cutting tools must be kept clean and sharp. A properly kept cutting tool is easier to control during operation. Use pneumatic tools and accessories in accordance with the above-mentioned instructions. Use the tools according to their purpose, taking into account the type and conditions of work. Using the tools for purposes that differ from those for which they were designed increases the risk of dangerous situations. While operating a pneumatic tool, take into account the possibility of fracturing the working tool, which may cause expulsion of its parts at high velocity and lead to serious injuries. Make sure the tool is rotating in the correct direction. Unexpected direction of rotation may be a cause of a dangerous situation. Do not place hands near the mobile elements of the pneumatic tool, as it may cause serious injuries. In case the socket of the collector is damaged, there is a risk of expulsion of parts of the tool at high velocity, leading to serious injuries. As a result of the turning moment, the tool or the reaction stick may turn. This may lead to serious injuries if the operator's body is within the range of the turning tool or the reaction stick. Adopt an appropriate position during work and be prepared for a turn of the tool. Solely the equipment destined to function with pneumatic tools may be used. Using inappropriate equipment may lead to serious injuries. In case the power supply is suddenly interrupted, the switch of the tool must be immediately released.

Repairs

The tool may be repaired solely in authorized service points that use only original spare parts. This will guarantee an appropriate level of safety of the pneumatic tool. Do not clean the pneumatic tool with petrol, solvents, or other inflammable liquids. The fumes may ignite, causing an explosion of the tool and serious injuries. The tool may only be maintained with high-quality materials. It is prohibited to use substances other than those mentioned in the service manual. Before replacing or dismantling the inserted tool, disconnect the compressed air supply duct.

Conditions of Operation

It is indispensable that the source of compressed air permits generating the appropriate working pressure. Should the pressure of the fed air be too high, it is necessary to use a reducer with a safety valve. The pneumatic device must be supplied with compressed air through a filter and lubricator system. This will guarantee both cleanliness and lubrication of the air with oil. The conditions of the filter and the lubricator must be revised before each use and, if necessary, clean the filter or replenish oil in the lubricator. This will guarantee appropriate operation of the machine and prolong its durability.

Only connecting elements specified in the user manual are allowed to be used in the tools. The tool used to drive connecting elements and the connecting elements specified in the manual are considered to constitute a single system from the point of view of safety.

To connect the tool to the pneumatic system, it is recommended to use snapping connections. The tool itself should have a non-sealing screwed connector, so that after the tool has been disconnected, there is no remaining air in it.

The tool must not be supplied with oxygen or other inflammable gases.

Tools should be connected solely to a supplying system in which it is not possible to exceed the pressure by more than 10% of the maximum value. In case of higher pressures, it is necessary to apply a reduction valve with a safety valve.

Tools may be repaired solely with original spare parts specified by the manufacturer or their representative. Repairs should be carried out by experts authorized by the manufacturer. Experts are persons who, through professional training or experience, have sufficient knowledge regarding machines used to drive connecting elements, and appropriate industrial safety regulations, accident prevention regulations, directives, and general technical regulations (e.g., CEN and CENELEC), to assess safe working conditions.

Racks supporting tools, installed for example in a working table, should be designed and manufactured by the rack producer to guarantee safe installation of the tool, prevent damage, deformation, or movement.

Maintenance of the tool is only possible using the lubricants specified in the manual.

Tools designed to drive connecting elements with contact actuation or constant contact actuation, marked with the symbol „Do not use on scaffolds or ladders”, must not be used for certain purposes (e.g., when using scaffolds, stairs, ladders, or similar constructions for changing position; for closing boxes or cages; for fastening transport safety systems).

The specified noise values are characteristic for the tool and do not apply to the noise emitted at the operation location, which depends on the working environment, the processed object, and its support. Individual means of noise reduction may be necessary. Regulate pressure to the minimum value sufficient for the task. In special cases, hearing protection is necessary.

The specified vibration values are characteristic for the tool and do not reflect manual action during operation. Manual action depends on grip strength, pressure, work direction, power supply adjustment, the processed object, or its support.

Before each operation, check that the safety device and release mechanism function properly and that all screws and nuts are tightened.

Do not modify any elements of the machine without prior manufacturer authorization. Do not dismantle any elements, such as the safety device, or cause their malfunction. Do not perform “emergency repairs” without appropriate tools and equipment. Regular maintenance according to manufacturer instructions is recommended.

Avoid impairment or damage, e.g., by perforation, engraving, unauthorized modifications, using hard templates, dropping, pushing along the floor, using as a hammer, or applying excessive force.

Never direct a working tool towards yourself or any other person.

Hold the tool to prevent injuries from possible rough movements caused by power supply disturbances or hard parts of the processed object. Do not start the machine towards empty space. This avoids danger from freely moving connecting elements and excessive stress in the tool.

When carrying the tool, disconnect it from the power supply system, especially when using ladders or adopting unusual positions. Carry the tool by the handle only, never with the trigger pressed.

Consider workplace conditions. Connecting elements may penetrate thin objects or slip off corners/edges, posing a danger. Use protective equipment such as hearing or sight protection.

Use of the Tool

Before each use, ensure no element of the pneumatic system is damaged. If damage is detected, replace it immediately with a new, undamaged element. Before each use, dry any condensed humidity inside the tool, compressor, and conduits.

Connection of the tool to the pneumatic system

Insert a few drops of SAE 10 viscosity oil into the air inlet. Screw the appropriate tip into the air inlet thread that allows connecting the air supply hose, tightly and securely (refer to diagram II). Make sure the tool magazine is empty; if not, empty it to avoid the risk of accidentally ejected fasteners.

The recommended connection method (refer to diagram IV) ensures effective use and prolongs the tool's service life. Connect the tool to the pneumatic system using a hose with the internal diameter shown in the table. Ensure the hose strength is at least 1.38 MPa.

If the product features the ability to change the direction of air outlet, direct it away from the human body. Prolonged exposure to a stream of compressed air can lead to cooling of the affected area, causing serious injuries.

Check the correctness of connection and operation by applying the tool outlet to a piece of wood or wood-based material and pressing the trigger once or twice.

Filling the magazine (V)

Note! The magazine should be filled only when the product is disconnected from the compressed air supply. Only fasteners listed in the user manual may be used. When filling, hold the tool so the outlet is not directed towards the user or others. Do not hold your finger on the trigger while filling.

Model Specific Instructions

YT-09201, YT-09202, YT-09203: Press the magazine latch and pull out the pusher. Insert the package of fasteners and push the pusher to secure them. Do not use different types and/or sizes of fasteners in one magazine cartridge.

YT-09211: Pull back the latch of the feed mechanism cover and open it, then open the magazine cover. The magazine has a raised floor for shorter fasteners; adjust its height by rotating the axle. Ensure the floor is locked. Load the fastener belt with fasteners directed towards the floor, free end towards the outlet. Splines of the feed mechanism should be between the first and second fasteners, with heads in the guide. Close and secure covers.

YT-09212, YT-09213, YT-09214: Similar to YT-09211, but floor adjustment involves raising the axle and turning clockwise to hook the spline into a notch (refer to diagram VII). Load fastener belt as described above. Close and secure covers.

Working with Product

The product does not have a trigger lock, meaning a single fastener is released each time the trigger is pulled. Subsequent operations require the trigger to return to neutral and be pulled again.

The product has a single sequential start system: both the trigger and the safety must be engaged. Press the tool in the nailing area and pull the trigger (refer to diagram VI).

If a fastener is nailed too deep, reduce pressure by 0.05 MPa increments. If a fastener protrudes, increase pressure by 0.05 MPa increments. Do not exceed the maximum pressure. It is recommended to use the lowest possible pressure to save energy, reduce noise, tool wear, and increase safety.

Maintenance

Never use petrol, solvents, or other inflammable liquids to clean the tool. Solvents may soften seals. Dry the tool thoroughly before use. If any irregularities occur, disconnect the tool from the pneumatic system immediately. Protect all pneumatic system elements from contamination.

Maintenance of the tool before each use

Disconnect the tool from the pneumatic system. Before each use, add a small amount of maintenance liquid (e.g., WD-40) to the air inlet. Connect the tool to the pneumatic system and run for approximately 30 seconds to distribute the liquid and clean the tool. Disconnect again. Add a small quantity of SAE 10 oil through the air inlet and special holes. It is recommended to use SAE 10 oil designed for pneumatic tools. Connect the tool and run briefly. Attention! WD-40 is not a lubricating oil. Wipe off excess oil; it may damage seals.

Other maintenance actions

Before each use, check for signs of damage. Keep drivers, tool holders, and spindles clean. Every six months or after 100 hours of operation, the device must be revised by qualified personnel in a repair shop. If used without the recommended air supply system, increase the frequency of these controls.

Troubleshooting

Stop using the tool immediately if any defect is detected. Repairs or replacements must be performed by qualified personnel in an authorized repair shop.

End of Use and Disposal

Once functioning is concluded, cleanse the casing, ventilation slots, switches, additional handle, and protections with a stream of air (at pressure not exceeding 0.3 MPa), a brush, or a cloth without chemical substances or cleaning liquids. Tools and handles must be cleansed with a clean cloth.

Worn tools are recyclable waste – do not dispose of them with domestic waste, as they contain substances harmful to people and the environment. Please assist in the economic management of natural resources and environmental protection by sending worn tools to a disposal point. To reduce waste quantity, recycling is necessary.
