Safety Instructions

Warning

Read all safety instructions and Notes. Any failure to comply with safety instructions and Notes could cause electric shock, fire and/or serious personal injury.

The term "power tool" used in the safety instructions refers to power tools that run on a mains power connection (with a power cable) and battery-operated power tools (without a power cable).

Work Area

General safety instructions for the use of power tools! Safety in the work area!

• Keep your work area clean, neat and well lit. Disorder and lack of light in the workplace can cause accidents.
• Do not use the power tool in an explosive environment containing any inflammable liquid, gas or powder. Power tools generate sparks that can ignite powders and fumes. Ensure that the power tool is not near sources of ignition while it is in use, such as open flames, cigarette smoke, incandescent wires and hot surfaces.
• Keep children and other people away when using the power tool. Any distraction can cause you to lose control of the tool.

Electrical Safety

• The tool plug should fit perfectly into the wall outlet. Do not modify the plug for any reason. Do not use adaptor plugs with earthed power tools. Original plugs reduce the risk of electric shock.
• Avoid body contact with earthed surfaces such as pipes, radiators, ovens and refrigerators, as this will increase the risk of electric shock.
• Do not expose power tools to rain or moisture. If water penetrates into the power tool, the risk of electric shock increases.
• Never carry or hang a tool by the cable or pull on the cable to disconnect the plug from the wall outlet. Keep the cable away from the heat, oil, sharp edges and moving parts. Damaged and tangled cables increase the risk of electric shock.
• Do not use the cable for purposes other than those for which it was designed.
• When you cannot avoid working with a power tool in a wet environment, always use a residual-current device. Using a residual-current device will reduce the risk of electric shock.
• When working outdoors, only use extension leads designed for outdoor use.

Personal Safety

• Pay close attention to what you are doing, be careful and use common sense when using the Mini Saw. If you are tired or under the effects of drugs, alcohol or medication, do not use the device. A single moment of inattentiveness while using the saw could cause serious injury.
• To reduce the risk of injury based on how you will use the device, use suitable personal protection equipment, including safety goggles, dust mask, non-slip footwear, helmet and hearing protection.
• Keep the device from accidentally starting up. Make sure the tool switch is in the OFF position before lifting it, carrying it or connecting it to the power source and/or rechargeable battery. Carrying the device with your finger on the ON/OFF switch or plugging it into the mains with the switch in the ON position can cause accidents.
• Keep children and other people away from the device during use. Any distraction can cause you to lose control of the device.
• Remove any adjusting wrenches before turning on the device. Leaving a wrench on the rotary part of the tool could cause injury.
• Try to adopt a good position and keep your balance at all times when using the device. This will make it easier to control the device in unexpected situations.
• Use suitable clothing. Do not wear loose clothing or jewellery. Keep hair, clothing and gloves away from moving parts. Loose clothing, jewellery and long hair can become trapped in moving parts.
• Whenever using devices that extract and collect dust, make sure they are well connected and used correctly. The use of dust-extraction systems reduces the risk of accidents caused by dust.

Safety Instructions for Saws with a Blade Guard

• Before each use, make sure the blade guard closes properly. Do not use the saw if the blade guard does not move freely and does not close immediately. Never hold or clamp the guard into the open position. If the saw is accidentally dropped, the guard may be bent. Make sure the guard moves freely and does not make contact with the blade or any other part at all cutting the angles and depths.
• Check the condition and operation of the guard spring. If the spring or guard does not work properly, have the saw repaired before using it. Damaged parts, sticky residue or the accumulation of the sawdust can make the blade guard work slower.
• Apply pressure to the saw’s base plate so it does not move to the side during perpendicular plunge cuts. Side movements can cause the blade to jam and cause recoil.
• Do not place the saw on the workbench or floor without checking if the blade guard is covering the blade. A blade without protection continues spinning due to inertia and the saw moves in the opposite direction of cutting while it cuts everything in its way. Always bear in mind the time it takes for the saw blade to stop spinning.

Additional Safety Instructions

• The grip should be clean and dry and should be kept away from oil and grease.
• Do not stop the cutting tool by pushing the blade to the side.
• Any defective switch, protective parts or other components should be replaced by an authorised technical service centre. Examine the extension lead regularly. If it is damaged, it can only be replaced by the manufacturer or an authorised service centre.
• When you use the tool outdoors, always connect a residual-current device.
• Warning! If you want to use the saw at home, especially on floors, ceilings and walls, always check to ensure that electricity, water and gas installations will not be damaged. If necessary, use a metal detector, which can be acquired in specialised shops. Bear in mind that in all houses, there are usually hidden pipes and wiring behind plaster and other types of cover, which means there is a risk of suffering from an electric shock or another kind of accident, not to mention damaging the building.

Other Risks

Even if you follow the instructions while using the power tools, you will always be exposed to some risks. The following is a description of the dangers associated with the construction and design features of this tool:

• Lung injuries if an anti-dust mask is not used.
• Loss of hearing if suitable hearing protection is not used.
• General health damage derived from the vibration of hands and arms if the tool is used for a long period of time and does not receive suitable maintenance or control.
• Cutting injuries if sharp objects are not handled with care and gloves are not worn.

Warning! When in operation, this power tool generates an electromagnetic field. Under certain circumstance, this field can have a harmful effect on active and passive medical implants. To reduce the risk of serious and fatal injury, people with medical implants are recommended to consult their doctor and the implant manufacturer before using this tool.

Instructions

Sawing Procedure

Danger:

• Keep hands away from the cutting area and do not touch the blade. Place your hand on the additional grip or the engine body. If you hold the saw with both hands, they cannot be hurt by the blade.
• Do not hold the workpiece on the bottom. The blade guard cannot protect you from the blade underneath the workpiece.
• Adapt the cutting depth to the thickness of the workpiece. You should only be able to see less than a complete length of the sawtooth under the workpiece.
• Never hold the workpiece you plan to cut in your hand while resting it on your leg. Attach the workpiece to something with stable support. It is important to properly attach the workpiece to minimise the risk of contact with your body, or the blade jamming and the losing control.
• Only hold the device by the insulated grips when performing jobs in which the tool could make contact with hidden electrical cables or the device’s own cable.
• To make longitudinal cuts, always use a stop or a straight cutting guide. This will provide greater cutting precision and will reduce the risk of jamming the blade.
• Always use the right size blade that adapts perfectly to the shape of the hole where they are inserted (round or star-shaped). Blades that do not fit correctly on the saw support will wobble and cause a lack of control.
• Do not use unsuitable or damaged washers or bolts to attach the new blades. The blade washers and bolts have been designed specifically for this saw for safe and optimum operation.

Before Using For the First Time
Unpacking

• Open the box and carefully remove the tool.
• Remove the packing materials.
• Remove the packing protection and transport materials (as applicable).
• Check to make sure the box contains all the parts.
• Check the tool and accessories to determine if it was damaged during transport.
• If possible, keep the box until the warranty expires. Then dispose of the box by taking it to a recycling centre.

Warning: Neither the tool nor the packing material is a toy. Children should not play with plastic bags, aluminium sheets or small parts; because they could choke on swallowing small parts.

Important Notes

• Before plugging the tool into the mains, make sure the information on the product identification label complies with the specification of the power source.
• While it is operating, the tool should always have a dust extractor attached to the dust extraction hose.

Warning: Always unplug the tool before making any adjustments to it.

Adjusting the Cutting Depth

• The cutting depth can be changed by adjusting the lever.
• Loosen the adjustment screw (3) and move the depth lever until the front end of the lever is on the mark of the depth scale you want (Figure 2). The even millimetre values on the depth scale are indicated with long lines and the odd values with short lines.
• Tighten the adjusting lever again.

Notes:

1. For optimum results when cutting wood, select a cutting depth that is greater than the thickness of the material.
2. To cut plastic, select a cutting depth that is greater than the thickness of the material. If the material begins to melt, just increase the cutting depth and clear up.
3. For optimum results when cutting metal, the cutting depth should be at least 1.0mm, greater than the thickness of the material.
4. When cutting wood or plastic, the cutting depth can be adjusted to the exact thickness of the material so that the surface below is not damaged. However, when this procedure is used, the bottom of the workpiece may not be completely clean.

Dust Extraction

Warning:

Working with some kinds of wood and metal or with paint that contains lead can generate harmful or toxic gases that are a risk for the user and other people in the work area. Always wear suitable personal protection and keep people from getting too close to the work area.

Extracting dust is very helpful for keeping the work area clean because a great deal of dust is produced when working with this power tool.

Because the cutting blade is almost completely enclosed in the saw body, extracting dust is particularly effective in this case. A dust extractor or vacuum cleaner can be attached to the hose (14), which is in turn attached to the connector for the dust extraction device.

• Unplug the tool and attach the hose to the connector for the dust extraction device (8).
• Use a flange to attach the hose.
• Check to make sure the blade guard moves freely. Use a cone-shaped adapter to connect the hose to a dust extractor or a vacuum cleaner. If necessary, wrap duct tape around the hose for added strength.

Notes:

• Make sure that the extractor can be used with a power tool. Most dry and wet household vacuum cleaners can be used.
• Using a dust extractor is very practical when making several cuts one after another because it reduces the need to stop as often to clean the tool and the work area.
• Always use a dust extractor when cutting materials that generate dust that can be harmful, such as certain kinds of wood flooring, medium-density fibreboard and ceramic.

Operation

Instructions for Use

The mini circular saw, along with the corresponding cutting tool, is suitable for making straight cuts in wood, wood-like material, aluminium, plastic and steel that has not undergone heat treatment. This tool should not be used to cut materials containing asbestos.

This saw was designed for household use and should only be used as described herein. Any use other than the one indicated here is not considered the intended use.

The user and not the manufacturer is responsible for any damage or injury derived from using the saw.

Operation/Start-up

With this tool, the material to be cut is held between the base plate and the support surface. The blade penetrates into the material to make a clean cut that is faster and safer.

Turning On and Off

• Side the ON/OFF switch (4) forward to turn on the tool. The device will be operating whenever the switch is moved forward.
• To turn off the power, slide the switch to the OFF position.

Working with the Mini Circular Hand Saw

•  Select the right blade for the material you are going to cut.
• Make sure the blade is sharp and in good condition.
• Adjust the blade to the desired cutting depth.
• Place the workpiece you want to cut on a table, workbench or any other suitable surface and hold it in place with clamps or a vice. Place sufficient scrap material under the workpiece so you do not make cuts in the support surface or break the blade due to contact with the hard support surface such as a concrete floor.
• Hold the power tool in your hand in a comfortable position. Your thumb or index finger should be resting on the ON/OFF switch (4). Make sure your hand does not cover the ventilation holes (6) on the front or back of the device.
• Place the base plate (1) on the workpiece. To leave a gap from the workpiece, place the saw so the back part of the base plate sticks out. Do not let the saw blade penetrate into the workpiece.
• Turn on the tool and wait a few seconds until the blade is moving at the operating speed. Press the lever for releasing the blade guard (12) and allow the blade to slowly penetrate into the workpiece while applying some pressure.
• Move the tool forward while you cut through the workpiece. Never move the tool backward while the blade is in the workpiece.
• Do not apply great force when cutting with the tool. Applying too much pressure creates wear and can tire you unnecessarily.
• Make sure the base plate (1) is always flat on the workpiece. This is particularly important when cutting narrow bars that are not completely covered by the base plate.

Cutting along a Line

Using the indicator on the front and rear of the blade guard makes it easier to cut along a straight line.

Plunge-Cutting

It is sometimes impossible to make plunge cuts in certain very hard materials.

• Adjust the cutting depth, connect the tool to the power source and place the base plate on the workpiece. Make sure the depth setting on the side is the same for all cuts.
• Turn on the tool and wait two seconds until the blade is spinning at the working speed. Then allow the blade to slowly penetrate into the workpiece while applying some pressure. Move the tool forward while you cut through the workpiece. Never move the tool backward while the blade is in the workpiece.
• When you reach the end of the cut, turn off the saw and take it out of the workpiece.

Cutting Difficult Materials and Materials that Create a Lot of Dust

Before trying to cut difficult materials, you should familiarise yourself with how the tool works by cutting wood. To cut hard materials like metal and some plastics, more pressure has to be applied from above.

Warning! Never cut a material that generates dust or dangerous fumes when working, such as some plastics and materials that contain asbestos.

Sheet Metal

• Adjust the cutting depth so it is at least 1mm greater than the thickness of the material. Always place scrap material under the workpiece.
• Eliminate any deep scratches and rusty areas from the surface of the material, since they make it much more difficult to move the tool forward.
• After every 2 minutes spent cutting the metal, you should stop for at least a 3-minute break.

Note: Use suitable cutting fluid if necessary.

Floor Tiles, Slate and Similar Materials

• Always use the right cutting blades for this job.
• Always connect the tool to a suitable dust extractor. The dust generated during cutting can be hazardous to the health and clog the blade guard.
• Place adhesive or duct tape on the base plate to facilitate cutting and prevent any scratching.

Drywall

1. This tool can be used to cut sheets of drywall but with certain limitations. Use it only to make cuts and always connect it to a dust extraction device while you are working. The dust can affect how the blade guard works.

Use & Care

• Do not force the tool. Use the right tool for the job you are doing. Using the right tool will allow you to work faster and safer within the range of available features.
• Do not use the tool if the switch does not work. A tool that cannot be turned OFF or ON by means of the switch is dangerous and should be repaired.
• Remove the plug from the wall outlet and/or remove the rechargeable battery before making any adjustments or changing a saw accessory and before storing the device. This preventive measure will reduce the risk of accidentally turning on the saw.
• Keep tools that are not in use out of reach of children. Do not let tools be used by people who do not know how they work or who have not read the instructions.
• Take care of power tools. Check that the moving parts work perfectly and do not jam. Also, check to ensure there are no broken or damaged parts that could affect tool operation. Always have damaged parts repaired before using the device again. Many accidents are caused due to failure to care for tools.
• Keep cutting tools clean and sharp. Tools whose cutting parts are well cared for and sharp do not jam and are easier to control.
• When using the power tools, accessories and work tools, etc. Always follow these instructions and bear in mind the working conditions and the task to be performed. Using power tools for uses other than those for which they were designed can cause dangerous situations.

Service

• Mini Saw should be repaired only by qualified persons and only using original replacement parts. This will guarantee that the saw continues to be safe.
• If the power cable is damaged, it should be replaced by the manufacturer, the after-sales service or by a qualified person to prevent risks.
• Turn off the saw immediately when:

1. The power plug and/or power cable are defective.
2. The switch is defective.
3. Smoke comes out or there is a burning smell.

During actual use of a power tool, depending on how the tool is being used, the amount of vibration emitted may be different from the amount specified. To protect the user, it is necessary to establish safety measures based on the assessment of interruptions on the course of real use (in this context, all the stages in the opening cycle should be considered, such as the duration of time in which the tool is switched off and the time in which it is on but is operating without a load).

Troubleshooting

Reasons for Recoil and Instructions for Preventing Recoil

1. Recoil is a sudden reaction that occurs when, due to a jammed or misaligned blade, the device jerks, jumps away from the workpiece without control and moves in the direction of the operator.
2. When the blade jams or gets stuck in the cutting groove, it becomes blocked and the force of the motor jerks the device towards the operator.
3. If the blades twists or cutting angle is misaligned, the blade teeth at the back edge of the blade can become jammed on the surface of the workpiece, come out of the cutting groove and jump in the direction of the operator.
4. Recoil is due to improper or unsuitable use of the saw and can be avoided by following the precautionary measures listed below:

• Grasp the saw with both hands and brace your arms so they stop any recoil. Always keep your body positioned to the side of the cutting blade so it is never in line with the blade. In the event of recoil, the circular blade can jerk back, but this recoil can be controlled by the operator if suitable precautions are taken.
• If the cable jams or you stop working, turn off the saw and hold onto the workpiece until the blade has come to a complete stop. Never attempt to remove the blade from the workpiece or pull the saw backward while the blade is moving because this could cause recoil. Examine the blade to determine the cause of the jam and correct the problem.
• When you want to turn on the saw again when it is stuck in the workpiece, centre the blade in the cutting groove and make sure the tooth is not stuck in the workpiece. If the blade is jammed, turning the saw ON again could make it come out of the workpiece and cause recoil.
• Provide support for large panels to reduce the risk of recoil due to blade jamming. Large panels can sag due to their own weight. Large panels should be supported in two places: near the cutting groove and near the end of the panel.
• Do not use damaged or dull blades. Blades with dull or poorly aligned teeth produce a cut that is too narrow and causes excessive friction, blade jamming and recoil.
• Before you start sawing, adjust the cutting depth and angle. If these adjustments are changed during sawing jobs, the blade can jam and cause recoil.
• Pay special attention when making plunge cuts into walls and hidden areas. The blade may become jammed on hidden objects when sawing and cause recoil.

To reduce the amount of noise and vibrations as much as possible

• Use only suitable power tools.
• Clean and maintain the power tool regularly.
• Adopt a work method based on the power tool.
• Do not overload the tool.
• Always have the tool checked by a professional whenever necessary.
• Disconnect the tool from the mains when not in use.
