GENERAL POWER TOOL SAFETY WARNINGS
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety
   a) Keep the work area clean and well lit. Cluttered or dark areas invite accidents.
   b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
   c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2. Electrical safety
   a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
   b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
   c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
   f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3. Personal safety
   a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
   b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
   d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
   e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
   g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust related hazards.
   h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

4. Power tool use and care
   a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
   b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   c) Disconnect the plug from the power source and/ or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
   h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Battery tool use and care
   a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
   b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
   c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
   d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
   e) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
   f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion. NOTE The temperature „130 °C“ can be replaced by the temperature „265 °F“.
   g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

6. Service
   a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
   b) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

SAFETY WARNINGS FOR PLUNGE SAWS

• Warning: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade
• Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
• Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
• Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimise body exposure, blade binding, or loss of control.
• Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
• Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
• Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.b

Kickback causes and related warnings

• Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;
• When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;
• If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.
• Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.
• Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.
• When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw teeth are not engaged into the material. If saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted.
• Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
• Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.
• Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
• Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

Safety instructions guard

• Check guard for proper closing before each use. Do not operate the saw if guard does not move freely and enclose the blade instantly. Never clamp or tie the guard with the blade exposed. If saw is accidentally dropped, guard may be bent. Check to make sure that guard moves freely and does not touch the blade or any other part, in all angles and depths of cut.
• Check the operation and condition of the guard return spring. If the guard and the spring are not operating properly, they must be serviced before use. Guard may operate sluggishly due to damaged parts, gummy deposits, or a buildup of debris.
• Assure that the guide plate of the saw will not shift while performing the ‘plunge cut’ when the blade bevel setting is not at 90°. Blade shifting sideways will cause binding and likely kick back.
• Always observe that the guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

ADDITIONAL SAFETY WARNINGS

• Do not reach into the chip ejector with your hands. They could be injured by rotating parts.
• Do not work overhead with the saw. In this manner you do not have sufficient control over the power tool.
• Use appropriate detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage.
• Do not operate the power tool stationary. It is not designed for operation with a saw table.
• Do not saw ferrous metals. Red hot chips can ignite the dust extraction.
• When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
• Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
• Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
• Plunge saws are intended to cut wood or wood-like products, they cannot be used with abrasive cut-off wheels for cutting ferrous material such as bars, rods, studs, etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
• Use only saw blades that are marked with a speed equal or higher than the speed marked on the machine.
• Only use saw blades that match the specifications given in this operating manual and that have been tested and marked in accordance with EN 847-1 (TCT & HSS blade) and EN 13236 (Diamond blade).

When mounting the saw blade, wear protective gloves. Danger of injury when touching the saw blade.
Only use saw blades that correspond with the characteristic data given in the operating instructions.
Do not under any circumstances use grinding discs as the cutting tool.

Blade replacement without removing the guard (Fig. D)

• Press the spindle lock button (24) to prevent the saw from turning. (Fig. D-1)
• Keep the spindle lock button (24) pressed and loosen the clamping nut (26) using the hex key (19). (Fig. D-2)
• Remove the mounting flange (25).
• Loosen the saw depth limiter (3) using the hex key (19) and press the guard to remove the blade. (Fig. D-3)
• Keep the guard pressed and place the new blade onto the blade shaft. Ensure the hole locates correctly and the teeth point in the direction of the curved arrow. (Fig. D-3)
• Place the mounting flange (25) insuring the long sides of the mounting flange correspond with the long sides of the blade shaft.
• Press the spindle lock button (24) pressed and tighten the clamping nut (26) using the hex key (19). (Fig. D-4)
• Make sure the blade rotates smoothly by rotating the sawblade at least one turn. Check if the guard functions correctly.

Attaching the parallel guide (Fig. C)

• Attach the parallel guide (22) on the right side of the machine, as shown in Fig. C-1.
• Lock the guide down by turning the adjustment knob (23) clockwise.

Assembling the guide rail (Fig. A, F)

• Slide the saw coupling bar (12) into the groove on the guide guide rail (11).
• Position the coupling bar exactly in-between the two guide rails as shown in figure F-1.
• Tighten the grub screws on the coupling bar, fixating the two guide rails.
• Slide a clamp (13) into each of the two grooves on the guide rail (11).
• Firmly tighten the clamp onto the workpiece. Make sure both clamps are always firmly mounted and tightened onto the workpiece and a surface (table).
• Make sure the rail guide (14) retains a good grip onto the guide rail (11) when using the saw, as shown in figure F-3.

OPERATION

Switching the machine on/off (Fig. A)

• Slide the on-/off switch (4) forward.
• Release the on-/off switch to switch the machine off.

Adjusting the cutting depth (Fig. E)

• Loosen the saw depth limiter (3) using the hex key (19) and move the saw depth limiter to the required saw depth. The sawing depth ‘A’ is shown in Fig. E-2.
• Tighten the saw depth limiter (3) using the hex key (19).

Speed adjustment (Fig. A)
The required speed can be adjusted by using the Speed adjustment knob (7). Also during running the rotational speed can be adjusted.

• To increase the speed, turn the Speed adjustment knob (7) clockwise.
• To decrease the speed, turn the Speed adjustment knob (7) anti-clockwise.

The required speed depends on the material and can be determined by practical testing.

Optimum use

• For optimal result when sawing wood, the cutting depth should be set slightly greater than the thickness of the chosen material.

• When cutting plastic, the cutting depth should also be greater than the thickness of the material.
  If the material begins to melt, then setting a greater depth of cut usually resolves the problem.

• Hold the work using clamps or a vice to have both hands free to operate the saw.

• Let the saw do the job. Do not put undue pressure on the saw.

Sawing

• Check the technical data to see whether the saw is suitable for use with the material to be sawn.
• Fit a suitable blade. Make sure the blade is sharp and undamaged.
• Set the sawing depth.
• Place the material to be sawn on a flat surface, such as a work bench, a table or the floor. If, for example, you are working on a concrete floor, place something, such as a piece of cardboard, under the material to protect the surface and the blade.
• Insert the mains plug into the mains.
• Hold the saw firmly and fit the metal base plate to the material to be sawn. Make sure the rear of the plate protrudes over the workbench. Do not yet press the saw into the object to be sawn.
• Turn on the saw and wait a couple of seconds until the saw is moving at full speed. Press the saw slowly and carefully, but firmly, into the material. Next, push the saw forwards along the cutting line. Never pull the saw backwards.
• Only a small force is required to lead the saw along the cutting line. Too much force will cause damage and fatigue to the blade and the saw.
• Make sure the base plate is always flat against the object to be sawn. This is particularly important at the start and finish points of the sawing line or when small strips must be sawn and the base plate is not supported everywhere.
• After sawing, lift the saw upwards and turn it off. If a lot of sawdust has been created, allow the saw to continue running until all the dust has been removed.

Always saw in the forwards direction. Never pull the saw backwards. If you do not have much experience using the saw, first practice sawing wood until you become more  skilled.
It is not possible to cut pieces out of some hard materials.

Warning! Never saw material where harmful substances are released, such as PTFE or  asbestos.

Ceramic tiles and slate

• Use a suitable blade. It is necessary to use dust extraction, because the dust which is created can hinder the movement of the protective cover.
• Place protective tape or PVC tape on the base plate or on the object to be sawn. This makes it easier to saw and protects the tiles against becoming scratched.

Practice sawing wood before trying something more complicated, such as metal or some types of plastic. More force is required to hold the object to be sawn and you may  sometimes have to use clamps to keep the object in place.

Dust extraction (Fig. A)
The Mini plunge saw is a powerful saw. A lot of dust will be produced when sawing. Since the blade is fully enclosed, it is necessary to extract the dust.

A vacuum cleaner can be attached to the saw’s dust extraction pipe (8) using the dust adapter included with the machine.

• Make sure the vacuum cleaner is suitable for use with an electrical machine. In general, household water and dust vacuum cleaners are suitable.
• It is recommended to use dust extraction when a lot of sawing is to carried out, because less breaks will then be required to clean the saw and the surroundings.
• It is necessary to extract the dust when sawing dangerous materials, such as hardwood, MDF and ceramics.
• It is recommended to extract dust if you wish to keep the work area clean.
• It is necessary to extract the dust if the material to be sawn is damp.

MAINTENANCE

Before cleaning and maintenance, always switch off the machine and remove the mains plug from the mains.
Clean the machine casings regularly with a soft cloth, preferably after each use. Make sure that the ventilation openings are free of dust and dirt. Remove very persistent dirt using a soft cloth moistened with soapsuds. Do not use any solvents such as gasoline, alcohol, ammonia, etc. Chemicals such as these will damage the synthetic components.
