GENERAL POWER TOOL SAFETY WARNINGS

Warning! Please read all safety warnings, illustrations and specifications provided with this power tool. Failure to follow

EN

them may result in electric shock, fire or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" used in the warnings refers to all corded and cordless electric power tools.

Workplace safety

Keep your work area clean and well lit. Clutter and poor lighting can cause accidents.

Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or fumes.

Power tools create sparks which may ignite the dust or fumes.

Do not allow children or bystanders into the work area. Loss of concentration can cause loss of control.

Electrical safety

The plug on the electric cord must match the outlet. Do not modify the plug in any way. Do not use any plug adapters with grounded power tools. An unmodified plug that matches the outlet reduces the risk of electric shock.

Avoid body contact with grounded surfaces such as pipes, radiators, and refrigerators. Grounding your body increases the risk of electric shock.

Do not expose power tools to precipitation or moisture. Water or moisture entering a power tool will increase the risk of electric shock.

Do not overload the power cord. Do not use the power cord to carry, pull, or disconnect the plug from the wall outlet. Keep the power cord away from heat, oil, sharp edges, and moving parts. A damaged or entangled power cord increases the risk of electric shock.

When working outdoors, use extension cords designed for outdoor use. Using an extension cord designed for outdoor use reduces the risk of electric shock.

If using a power tool in a damp environment is unavoidable, a residual current device (RCD) should be used as protection against supply voltage. The use of an RCD reduces the risk of electric shock.

Personal safety

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while tired or under the influence of drugs, alcohol or medication. Even a moment of inattention while operating a power tool can result in serious personal injury.

Use personal protective equipment. Always wear eye protection. The use of personal protective equipment such as dust masks, non-skid safety shoes, hard hats, and hearing protection reduces the risk of serious personal injury.

Prevent accidental starting. Ensure that the power switch is in the “off” position before connecting to power source and/or battery pack, picking up or carrying the power tool. Carrying a power tool with your finger on the switch or energizing a power tool that has the switch in the “on” position can result in serious injury.

Remove any wrench or key that is used to adjust the power tool before turning it on. A wrench or key left attached to a rotating part of the power tool may result in serious injury.

Do not overreach or overextend. Maintain proper posture and balance at all times. This will make it easier to control the power tool in the event of unexpected situations while working.

Dress appropriately. Do not wear loose clothing or jewelry. Keep hair and clothing away from moving parts of the power tool. Loose clothing, jewelry, or long hair can be caught in moving parts.

If devices are provided for the connection of dust extraction or dust collection facilities, ensure that these are connected and used correctly. The use of dust extraction reduces the risk of dust-related hazards.

Don't let the experience gained from frequent use of the tool cause you to become careless and ignore safety rules.

Careless action can cause serious injuries in a split second.

Use and care of power tools

Do not overload the power tool. Use the correct power tool for the selected application. The correct power tool will provide better and safer work when used for the designed load.

Do not use a power tool if the power switch does not turn it on and off. A tool that cannot be controlled with the power switch is dangerous and must be repaired.

Disconnect the plug from the power outlet and/or remove the battery pack if detachable from the power tool before making any adjustments, changing accessories, or storing the tool. Such precautions will prevent the power tool from being switched on accidentally.

Store the tool out of the reach of children, do not allow persons unfamiliar with the power tool or these instructions to use the power tool. Power tools are dangerous in the hands of untrained users.

Maintain power tools and accessories. Check the tool for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. Any damage should be repaired before using the power tool. Many accidents are caused by poorly maintained tools.

Cutting tools should be kept clean and sharp. Properly maintained cutting tools with sharp edges are less likely to bind and are easier to control during operation.

EN

Use power tools, accessories and attachments etc. in accordance with these instructions, taking into account the type and conditions of work. Use of tools for work other than those designed may result in a hazardous situation.

Keep handles and gripping surfaces dry, clean and free from oil and grease. Slippery handles and gripping surfaces do not allow safe operation and control of the tool in hazardous situations.

Repairs

Have your power tool repaired only by authorized service centers, using only original spare parts. This will ensure proper safety of your power tool.

SAFETY WARNINGS FOR RECIPROCATING SAWS

Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own wire. The cutting tool contacting a live wire may make exposed metal parts of the power tool live and could give the operator an electric shock.

Use clamps or other practical methods to securely secure and support the workpiece on a stable platform. Holding the workpiece by hand or pressing it against your body makes it unstable and may lead to loss of control.

INSTALLATION OF EQUIPMENT ELEMENTS

NOTE! Accessories may only be installed when the power supply is disconnected. Remove the battery from the power tool socket!

The saw is delivered complete. After opening the factory packaging, check if all accessories have been packed.

PREPARING FOR WORK

Attention! All activities related to the assembly and replacement of saw blades, adjustment and maintenance of the power tool must be carried out with the power supply voltage of the tool switched off, therefore before starting these activities: Remove the battery from the power tool socket!

PREPARING FOR WORK

NOTE! All activities listed in this chapter must be performed with the supply voltage disconnected - the battery must be disconnected from the tool!

Battery Charging Safety Instructions

Caution! Before starting to charge, make sure that the body of the power supply, the cable and the plug are not cracked or damaged. It is forbidden to use a faulty or damaged charging station and power supply! Only the charging station and power supply provided in the set may be used to charge batteries. Using another power supply may cause a fire or destroy the tool. The battery may only be charged in a closed, dry room protected from access by unauthorized persons, especially children. Do not use the charging station and power supply without constant adult supervision! If it is necessary to leave the room where charging is taking place, disconnect the charger from the mains by unplugging the power supply from the mains socket. If smoke, a suspicious smell, etc. is emitted from the charger, immediately remove the charger plug from the mains socket!

The drill-driver is supplied with an uncharged battery, therefore, before starting work, it should be charged according to the procedure described below using the included power supply and charging station. Li-Ion batteries do not exhibit the so-called „memory effect“, which allows them to be charged at any time. However, it is recommended to discharge the battery during normal operation and then charge it to full capacity. If, due to the nature of the work, it is not possible to treat the battery in this way every time, then it should be done at least every few or a dozen cycles of work. Under no circumstances should batteries be discharged by short-circuiting the electrodes, as this causes irreversible damage! The battery charge status should also not be checked by short-circuiting the electrodes and checking for sparking.

Battery storage

To extend the battery life, ensure proper storage conditions. The battery can withstand about 500 charge-discharge cycles. The battery should be stored in a temperature range of 0 to 30 degrees Celsius, with a relative humidity of 50%. To store the battery for a longer period of time, it should be charged to about 70% of its capacity. In the case of longer storage, the battery should be charged periodically, once a year. Do not over-discharge the battery, as this shortens its life and may cause irreversible damage. During storage, the battery will gradually discharge due to leakage. The self-discharge process depends on the storage temperature, the higher the temperature, the faster the discharge process. If the batteries are not stored properly, the electrolyte may leak. In the event of a leak, secure the leak with a neutralizing agent, in the event of contact with the eyes, rinse the eyes thoroughly with water and then seek medical attention immediately. It is forbidden to use the tool with a damaged battery.

When the battery is completely worn out, it should be taken to a specialist waste disposal facility.

EN

Battery transportation

Lithium -ion batteries are considered hazardous materials by law. The user of the tool can transport the tool with the battery and the batteries themselves by land. No additional conditions need to be met. In the event of entrusting transport to third parties (e.g. shipping by courier), the regulations for the transport of hazardous materials must be followed. Before shipping, contact a person with appropriate qualifications on this matter.

It is forbidden to transport damaged batteries. During transport, dismantled batteries must be removed from the tool, and exposed contacts must be protected, e.g. with insulating tape. Batteries must be secured in the packaging in such a way that they do not move inside the packaging during transport. National regulations regarding the transport of hazardous materials must also be observed.

Battery charging

Insert the battery into the charger socket (V).

Connect the charger to a wall outlet.

There is a charger operation indicator light near the battery socket, as described in the „Charger operation indicator“ table. When charging is complete, disconnect the charger plug from the mains socket. Remove the battery from the charging station by pressing and holding the battery latch button, then slide the battery out of the charger socket.

Power battery

Ion batteries can be used for power supply: YT-828461, YT-828462, YT-828463, YT-828464, YT-828465, which can only be charged using YATO YT-828498, YT-828499, YT-828500, YT-828501, YT-828502, YT-828503, YT-828504 chargers. It is prohibited to use other batteries with a different rated voltage and which do not fit the device's battery socket. It is prohibited to modify the socket and/or battery to fit them.

Insert the battery into the power socket with the contacts facing the inside of the tool until the battery latch engages. Make sure the battery does not slide out during operation. Disconnect the battery by pressing and holding the latch, then sliding the battery out of the tool housing.

Installing and replacing the saw blade (II)

Check whether the installed saw blade is not damaged, cracked, whether the cutting teeth are not broken, etc. If any damage is found, replace the saw blade with a new one.

Blades vary depending on their intended use. A blade for wood and wood-based materials has wider-spaced teeth, while a blade for metal and plastics has finer teeth. Choose the right blade for the job you plan to do. The blade can be mounted with the teeth facing the bottom or top of the housing.

Note! When installing the saw blade, wear protective gloves. This will reduce the risk of injury.

Turn the spindle clamp and insert the saw blade holder into the spindle slot. Turn the clamp in the opposite direction and make sure that the blade is correctly secured: the clamp returns to its original position, the saw blade cannot be pulled out of the spindle.

Adjusting the height and angle of the foot (III)

The cutting height can be adjusted by adjusting the foot height. To do this, turn the lever located on the front of the housing clockwise, set the foot to the desired height, and turn the lever counterclockwise until it locks in place with the catch. Make sure that the foot does not change height during operation. The foot can be adjusted gradually.

EN

The foot allows for smooth adjustment of the runner angle, to do this, tilt it relative to the foot guide. This allows you to change the cutting angle without lifting the foot from the surface of the cut material.

USING THE TOOL

Before starting work, make sure that the saw blade is not damaged and is mounted correctly. Put on eye protection, ear protection and work gloves. Secure the workpiece to the work station, e.g. with carpenter's clamps, a vice, etc. Never hold the material being cut only with your hands or other parts of your body. When cutting, support the material at its edges and near the cutting line. Supports should be placed on both sides of the cutting line so that the saw blade does not jam in the kerf during cutting. During cutting, the foot must rest on the material being cut with its entire surface.

Turning the saber saw on and off

At the work site, make sure that the surface is even, stable and free of contamination.

Adopt a confi dent and stable stance.

Hold the tool by the handle. Do not rest the working parts of the tool against any object or item.

Slide and hold the switch lock, press the switch with your finger and hold it. Check that the blade moves freely and that the tool does not vibrate suspiciously or excessively. There is no smoke or suspicious smell coming from it. If you notice any deviations from correct operation, turn the tool off, disconnect the plug from the mains and take it to an authorised repair centre.

It is not necessary to hold the switch lock during operation.

The tool is switched off by releasing the pressure on the switch. After switching off, the blade may continue to move for some time.

Cutting wood (VI)

Before starting to cut, draw a cutting line with a carpenter's pencil. Then rest the tool on the shoe and align the blade with the drawn line, then turn on the tool, allow the tool to reach its rated speed and start cutting. When cutting, do not apply too much pressure on the shoe and blade, as this can cause the working tool to break.

Plunge cutting

Note! Plunge cutting should only be performed in soft materials such as softwood or plasterboard. Never perform plunge cutting in metal or other hard materials.

For plunge cutting, use a short blade. Set the speed to maximum. Place the edge of the shoe against the material being cut and turn the tool on. While pressing, allow the blade to plunge into the material until the shoe is fully seated against the material being cut. Continue cutting along the marked line.

When cutting wood, start the cut at a lower speed and increase it as you cut.

Cutting at the edge

Note! For cutting close to the edge, special saw blades with increased flexibility should be used.

It is possible to cut right next to walls, floors and other hard-to-reach places. For example, when cutting pipes. When cutting, make sure that the blade will constantly pass through the entire cross-section of the material being cut. It is forbidden to cut around a wall, this can cause the tool to bounce back towards the operator.

It is recommended to install the saw blade with the blade turned 180 degrees from the normal position. This will provide easier cutting.

Cutting holes

Note! When cutting holes, use blades designed for cutting arcs.

Before starting work, draw a cutting line. Then drill a hole with a drill, insert the saw blade into the hole and start cutting.

Cutting metal

Note! It is important to choose the right type of blade for the type of metal being cut. This will ensure greater safety of work and extend the life of the blade.

When cutting thin sheets of metal. Place it between two pieces of wood. This will give you a smooth cut line and reduce vibrations during operation.

It is recommended to use a coolant suitable for the type of metal. If possible, a thin film of oil should be spread on the area where the saw foot will move. This will make it easier to operate the saw.

Additional notes

The tool must not be overloaded, the temperature of the external surfaces must never exceed 60 °C.

After finishing work, turn off the tool, remove the battery from the tool socket, and then perform maintenance and inspection.

EN

MAINTENANCE AND INSPECTIONS

NOTE! Before starting any adjustments, technical service or maintenance, remove the battery from the product socket. After finishing work, check the technical condition of the power tool by visually inspecting it and assessing: the body and handle, operation of the electric switch, patency of the ventilation slots, sparking of the brushes, noise level of bearings and gears, start-up and smooth operation. During the warranty period, the user may not install power tools or replace any components or parts, as this will void the warranty. Any irregularities observed during inspection or during operation are a signal to carry out repairs at a service point. After finishing work, the housing, ventilation slots, switches and covers should be cleaned, for example, with an air jet (with a pressure of no more than 0.3 MPa), a brush or a dry cloth without using chemicals or cleaning fluids. Clean the tools and handles with a dry, clean cloth.
