GENERAL WARNINGS FOR THE SAFETY OF POWER TOOLS

Warning! Read all safety warnings, illustrations and specifications provided with this power tool. Failure to do so may result in electric shock, fire or serious injury.

Keep all warnings and instructions for future reference.

The term "power tool" used in warnings applies to all tools driven by power both wired and wireless.

EN

Workplace safety

Keep the workplace well-lit and clean. Disorder and poor lighting can be causes of accidents.

Do not work with power tools in an environment with an increased risk of explosion, containing flammable liquids, gases or vapors. Power tools generate sparks that can ignite dust or fumes.

Children and third persons should not be allowed to enter the workplace. Loss of concentration can result in loss of control.

Electrical safety

The plug of the electric cable must match the power socket. You must not modify the plug in any way. Do not use any plug adapters with earthed power tools. An unmodified plug that fits the outlet reduces the risk of electric shock.

Avoid contact with earthed surfaces such as pipes, radiators and coolers. Grounding the body increases the risk of electric shock.

Do not expose power tools to contact with atmospheric precipitation or moisture. Water and moisture that gets inside the power tool increases the risk of electric shock.

Do not overload the power cable. Do not use the power cord to carry, pull or unplug the power plug from the power outlet.

Avoid contact of the power cable with heat, oils, sharp edges and moving parts. Damage or entanglement of the power cord increases the risk of electric shock.

In the case of working outside closed rooms, use extension cords intended for work outside closed rooms. The use of an extension cord adapted for outdoor use reduces the risk of electric shock.

When using a power tool in a humid environment is unavoidable as a protection against supply voltage use a residual current device (RCD). The use of RCD reduces the risk of electric shock.

Personal safety

Stay alert, pay attention to what you do and keep common sense while working with the power tool. Do not use a power tool when you are tired or under the influence of alcohol or medication. Even a moment of inattention while working can lead to serious personal injury.

Use personal protective equipment. Always wear eye protection. The use of personal protective equipment such as dust masks, anti-slip safety shoes, helmets and hearing protection reduce the risk of serious personal injury.

Prevent accidental operation. Make sure that the electric switch is in the “off” position before connecting to the power supply and / or battery, lifting or moving the power tool. Moving the power tool with the finger on the switch or powering the power tool, when the switch is in the “on” position can lead to serious injuries.

Before turning on the power tool remove any keys and other tools that were used to adjust it. The key left on the rotating parts of the power tool can lead to serious injuries.

Do not reach and do not lean too far. Keep the right attitude and balance all the time. This will allow easier control over the power tool in case of unexpected work situations.

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

If the devices are fitted for the connection of dust extraction or dust collection, make sure that they are connected and used properly. The use of dust extraction reduces the risk of dust hazards.

Do not let the experience acquired from frequent use of the tool resulted in carelessness and ignoring safety rules.

Carefree action can cause serious injuries in a fraction of a second.

Use and care of the power tool

Do not overload the power tool. Use the power tool appropriate for the selected application. The right power tool will provide a better and safer job if used according to the designed load.

Do not use the power tool, if the electric switch does not allow switching on and off. Power tool, which cannot be controlled by means of a power switch is dangerous and must be returned for repair.

Disconnect the plug from the power socket and / or remove the battery if it is detachable from the power tool before adjusting, changing accessories or storing the tool. Such preventive measures will allow you to avoid accidentally turning on the power tool.

Keep the tool out of the reach of children, do not let people who do not know how to operate the power tool or these instructions use a power tool. Power tools are dangerous in the hands of untrained users.

Maintain power tools and accessories. Check the tool for mismatches or jams of moving parts, damage to parts and any other conditions that may affect the operation of the power tool. Damage must be repaired before using the power tool.

Many accidents are caused by incorrectly maintained tools.

Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp edges are less prone to jamming and are easier to control when working.

Use power tools, accessories and inserted tools etc. in accordance with these instructions, taking into account the type and conditions of work. The use of tools for work other than designed is likely to result in a dangerous situation.

Handles and gripping surfaces must be dry, clean and free from oil and grease. Slippery handles and gripping surfaces do not allow for safe operation and control of the tool in dangerous situations.

Repairs

Repair the power tool only in authorized facilities using only original spare parts. This ensures proper operation safety of the power tool

SAFETY INSTRUCTIONS FOR CIRCULAR SAWS

Safety instructions for circular saws

Keep your hands away from the cutting area and the saw blade. Hold the other hand on the auxiliary handle or on the motor housing. If the power saw is held by both hands, they cannot be injured by the saw blade.

Do not reach under the workpiece with your hand. The guard cannot protect you from the saw blade below the workpiece.

Adjust the cutting depth to the workpiece thickness. It is recommended that the saw blade protrudes below the cut material less than the tooth height.

Never hold the cut workpiece in your hands or on the leg. Attach the workpiece to a stable base. Good attachment of the workpiece is important to avoid risk of contact with the body, jamming of the saw blade or loss of cutting control.

Hold the power saw by its insulated surfaces designed for that purpose during operation during which the saw blade may have contact with live wires or the power saw power cord. Contact with “live wires” may also lead to metal parts of the power tool “becoming live” leading to electrocution of the operator.

When performing longitudinal cutting, always use a guide for longitudinal cutting or an edge guide. This will improve cutting accuracy and reduce the possibility of the saw blade jamming.

Always use saw blades with correct dimensions and shapes of mounting holes (e.g. diamond or round shape). Saw blades that do not fit into the mounting bracket may work eccentrically, causing a loss of work control.

Never use damaged or improper washers or bolts to mount the saw blade. The washers and bolts mounting the saw blade have been specially designed for the power saw to ensure optimum operation and safety of use.

Reasons for kickback and kickback prevention

A kickback is a sudden reaction to the pressed, stopped or misaligned saw blade. It causes uncontrolled lifting and movement of the power saw towards the operator.

If the saw blade is pressed or stopped during cutting, the blade is blocked and the motor reaction causes a sudden movement of the power saw towards the operator.

If the saw blade is bent or misaligned, the teeth and the rear edge can escape from the saw cut and move towards the operator. The rear kickback results from misuse of the power saw or improper procedures or operating conditions. It can be avoided by taking appropriate precautions given below.

Hold the power saw firmly with both hands, with arms positioned to withstand the force of the rear kickback. Adopt a body posture on one side of the power saw but not in the cutting line. Rear kickback can cause the power saw to move backwards abruptly, but the force of the rear kickback can be controlled by the operator if appropriate precautions are taken.

When the saw blade jams or stops cutting for some reason, release the power switch button and do not move the saw in the material until the saw blade stops completely. Never attempt to remove the power saw from the cut material or pull it backwards until the saw blade moves or can cause a rear kickback. Examine and take corrective actions to eliminate the cause of disc jamming.

In case of restarting the power saw in the workpiece, centre the saw blade in the saw cut and check that the saw blade teeth are not caught in the material. If the saw blade jams when the power saw is restarted, it may slide-out or cause the kick-back against the workpiece.

Support large panels to minimise the risk of the blade being jammed and kicked back. Large panels tend to bend under their weight. The supports should be placed under the panel on both sides, close to the cutting line and close to the edge of the panel.

Do not use blunt or damaged saw blades. Blunt or incorrectly positioned saw blade teeth make a narrow saw cut causing excessive friction, saw blade jamming and rear kickback.

Adjust the cutting depth and saw blade angle clamps securely before cutting. Changing the saw blade adjustments during cutting can cause jamming and rear kickback.

Take special care when performing “plunge cutting” towards existing walls or of other dead end spaces. A protruding saw blade can cut other objects, causing a rear kickback.

Additional safety instructions for circular saws

Before each use, check that the lower cover is correctly put on. Do not use the circular saw if the lower cover does not move freely and does not close immediately. Never attach or leave the lower cover open. If the circular saw is accidentally dropped, the lower cover can be bent. Lift the lower cover with the pull-back handle and make sure that it moves freely and does not touch the disc or other part for each angle and cutting depth adjustment.

Check the operation of the lower cover spring. If the cover and spring do not function properly, repair them before use. The lower cover may operate slowly due to damaged parts, sticky deposits, or soil accumulation.

Manual retraction of the lower cover is permitted only for special cuts such as “plunge cut” and “complex cut”. Lift the lower cover with the pull-back handle and as the saw blade sinks into the material, the lower cover should be released. For all other cuts, it is recommended that the lower cover operates automatically.

Always check whether the guard covers the saw blade before placing the circular saw on the workbench or floor. The unprotected edge of the saw blade will cause the circular saw to retract cutting anything on its path. Be aware of the time it takes to stop the disc after turning off the tool.

EN

Additional safety instructions for power saws with splitting wedges

Use a suitable splitting wedge adapted to the used saw blade. The splitting wedge must be thicker than the body of the saw blade, but thinner than the spacing of the saw blade teeth.

Adjust the splitting wedge according to the description in this instructions manual. Incorrect adjustment, incorrect positioning and misalignment may render the splitting wedge ineffective in preventing rear kickback.

Always use a splitting wedge except when plunge cutting. The splitting wedge must be reinstalled after the plunge cutting has been completed. The splitting wedge causes interferences during plunge cutting and may cause rear kickback.

For proper operation, the splitting wedge must be recessed into the workpiece. The splitting wedge is ineffective in preventing rear kickback during short cuts.

Do not operate the power saw if the splitting wedge is bent. Even a slight bend can slow the speed of the guard closing.

EQUIPMENT INSTALLATION

ATTENTION! Only install the accessories when the supply voltage is disconnected. Pull the tool power cord plug out of the mains socket!

The power saw is supplied complete. After opening the factory packaging, check that all equipment items have been packed. Then check the condition of the connections and possibly tighten the screw connecting the base to the fixed guard and tighten the screws fixing the splitting wedge, if included with the power saw. Before first use, assemble the saw blade.

PREPARING FOR WORK

Before starting work, make sure that the housing body and the connection cable with a plug are not damaged. In case of damage, do not proceed with work.

Caution! All activities related to the assembly and replacement of saw blades, adjustment and maintenance of the power tool should be carried out with the disconnected power supply to the tool. Therefore, before proceeding with these activities: Pull the power saw power cord plug out of the power socket!

Saw blades

Select a saw blade designed to cut the selected type of material. The more teeth the saw blade has, the smoother the cutting edges will be. Saw blades with several dozen teeth are better suited for cutting thinner materials with a thickness of less than 1 cm and soft wood.

Note! Do not cut materials other than those specified in the instructions manual.

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

Do not use deformed or cracked blades!

Do not use blades made of high speed steel.

Do not use abrasive discs.

Do not use blades that do not meet the specifications given in this instructions manual!

Do not use a saw whose body is thicker or whose set is smaller than the thickness of the splitting wedge!

Do not use blades with an allowable maximum speed of less than 5500 rpm.

Saw blade installation and replacement

Note! Due to the risk of injury from sharp edges of the saw, all assembly operations must be carried out with protective gloves.

Note! When replacing or assembling the saw blade, do not disassemble the saw blade guards!

Press the spindle lock button (II) and use the key to slowly turn the spindle until the lock stops rotating the spindle. Use a wrench to hold the locking button to unscrew the screw securing the circular saw blade. Remove the external mounting flange. Install a circular saw on the inner mounting flange so that the saw hole is aligned with the protruding part of the flange (III). Fix the external fixing flange and tighten the fixing screw (III).

Check that the circular saw has no side play and that it rotates freely without snagging on the saw blade guard. Try to do this by turning the saw by hand by at least one full revolution.

Note! Before installing the circular saw, thoroughly clean the place of installation (spindle and mounting flanges), as well as the interior of the shields from dust and chips generated during operation.

Adjusting the cutting depth (IV)

If necessary, the tool allows adjustment of the cutting depth, which is facilitated by a graduated guide (located on the back of the tool). To do this, unlock the lever on the graduated guide by moving it to the upper position, set the desired cutting depth and then move the lever to the lower position to lock.

EN

Cutting angle adjustment (V)

The tool allows cutting planes at an angle between 0^ and 45^ . To do this, unscrew the locking knob on the back and front of the tool, set the desired angle on the scale located on the back of the tool and tighten both locking knobs firmly and securely.

Connecting to the dust extraction system

The machine has been adapted to be connected to an external dust extraction system, e.g. an industrial vacuum cleaner.

The connection must be made using a flexible hose and a possible adapter that allows the hose to be connected to the dust extraction opening. Replaced parts are not included in the machine's equipment and must be purchased separately. When connecting, follow the instructions supplied with the installation. The connection must be made in such a way that none of the components of the system restricts the freedom of operation of the machine. None of the components of the system may become clogged with the rotating circular saw or block the movement of the movable saw blade guard.

Preparation for use with a guide (available separately)

If precise straight line cutting is required, the YATO YT-821534 guide bar can be used. Cutting with a guide bar is also recommended when machining particularly long materials. The guide can be fixed to the material to be cut using the clamps supplied with the guide. To do this, insert the clamp into the guide bar slot. Tighten the clamp on the material to be cut by tightening the locking screw. Fix the second clamp in the same way. To remove the clamp, unscrew the locking screw and then remove the clamp.

The saw base has a suitable notch for the guide bar lug. The knobs on the base of the saw are used to set the resistance with which the base of the saw will move on the guide bar. To adjust the resistance, loosen the knob retaining screw (VI) with a screw-driver, turn the knob to set the desired resistance, tighten the adjustment knob retaining screw. It is recommended to perform a travel test without the cutter motor running.

Additional notes

Do not use hands to remove loose bits, splinters and similar parts of the workpiece from the surroundings of the rotating saw blade.

Do not use the power saw outdoors during rain or other precipitation.

Do not guide the power saw with hands only. Always use auxiliary tools that allow guiding the power saw securely, such as a guide.

After checking the saw blade and its secure mounting, setting the depth, angle and cutting width, it is also necessary to:

Make sure that the movable guards operate freely, without locking

Do not lock the movable guard in the open position

Make sure that all rotating mechanisms of the guard system work properly

Make sure that the splitting wedge is set so that:

- the distance between the splitting wedge and the edge of the saw blade with teeth is not more than 5 mm,

- the edge of the saw blade with teeth does not protrude more than 5 mm beyond the lower edge of the splitting wedge.

- it is in the line of the rotating saw blade,

- it is not wider than the saw blade width

Always use a splitting wedge! (in power saws factory-equipped with a splitting wedge)

Do not remove the splitting wedge that protects the saw blade and the tool from damage.

Wear eye protection, hearing protection, and work gloves. Use dust masks.

Note! Always use hearing protection when working with hand-held power saws.

Attach the workpiece to a workstation (e.g. by means of hand-screw clamps, vices, etc.).

When cutting hard-wood surfaces (oak, beech, hornbeam), it is recommended to connect an external dust collector to the dust extraction port to collect generated dust during processing

TOOL OPERATION

The power saw can only be connected to the mains after performing all the activities listed in the chapter „Preparing for work”.

Adopt a firm and stable posture.

Grab the power saw in both hands by the handle and the additional handle (VII).

Switch on the circular saw by pressing the switch lock button and then pressing the electric switch (VIII). Release the switch lock button.

After switching the power saw on, keep it freely and check the uniformity of the operation with hearing. In the event of any suspicious sounds, cracks, etc., stop work immediately and repeat the steps indicated in chapter "Preparing for work".

Apply the power saw base to the workpiece surface in such a way that the saw blade does not touch the workpiece (IX).

Guide the power saw along the cutting line so that the power saw base has contact with the surface of the workpiece.

After pressing the power switch, allow the disc to reach the rated rotational speed and only then start cutting. It is forbidden to first apply the disc to the workpiece and then start the tool. This can jam or damage the disc or cause damage to the workpiece. This can lead to injuries.

EN

When resuming cutting, let the disc reach its rated rotational speed and then insert it into the kerf.

When cutting, the disc should be guided with a smooth motion, avoiding excessive pressure. The pressure to be exerted on the cutting head should not be greater than that which is sufficient to cut the workpiece. Avoid hitting the workpiece with the disc.

Note! Do not tamper with the movable saw blade guard. All cutting operations must be carried out with the circular saw held with both hands.

If the saw becomes jammed in the workpiece, switch off the saw immediately by releasing pressure on the electric switch and only then withdraw the circular saw. During cutting, pay special attention to the possibility of slipping or kickback of the power saw and therefore the risk of accident. When working, do not exert too much pressure on the workpiece and do not make sudden movements in order not to damage the saw blade and the power saw. Take regular breaks during work.

Do not overload the tool, the temperature of the external surfaces must never exceed 60°C.

After finishing work, switch off the power saw, unplug the tool cable from the power socket and perform maintenance and inspection.

MAINTENANCE AND OVERHAUL

ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been finished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following elements: body and handle, conductor with a plug and deflection, functioning of the electric switch, patency of ventilation slots, sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or cleaning liquids. Tools and handles must be cleansed with a clean cloth.
