General power tool safety warnings

WARNING: Read all safety warnings, instruc-tions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instruc-tions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

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

Electrical Safety

1. 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.
2.  Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of elec-tric shock if your body is earthed or grounded.
3.  Do not expose power tools to rain or wet con-ditions. Water entering a power tool will increase the risk of electric shock.
4.  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.
5.  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.
6.  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.
7.  Power tools can produce electromagnetic fields (EMF) that are not harmful to the user. However, users of pacemakers and other similar medical devices should contact the maker of their device and/or doctor for advice before operating this power tool.

Personal Safety

1. 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 med-ication. A moment of inattention while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
3. 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. 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.
4.  Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
5.  Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
6.  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.
7.  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.
8. Always wear protective goggles to protect your eyes from injury when using power tools. The goggles must comply with ANSI Z87.1 in the USA, EN 166 in Europe, or AS/NZS 1336 in Australia/New Zealand. In Australia/New Zealand, it is legally required to wear a face shield to protect your face, too.
9. It is an employer’s responsibility to enforce the use of appropriate safety protective equip-ments by the tool operators and by other per-sons in the immediate working area.

Power tool use and care

1.  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.
2.  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.
3.  Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjust-ments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
4.  Store idle power tools out of the reach of chil-dren 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.
5.  Maintain power tools and accessories. Check for misalignment or binding of moving parts, break-age 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.
6.  Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7.  Use the power tool, accessories and tool bits etc. in accordance with these instructions, tak-ing 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.
8. 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.
9. When using the tool, do not wear cloth work gloves which may be entangled. The entangle-ment of cloth work gloves in the moving parts may result in personal injury.

Battery tool use and care

1.  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.
2.  Use power tools only with specifically desig-nated battery packs. Use of any other battery packs may create a risk of injury and fire.
3.  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 termi-nals together may cause burns or a fire.
4.  Under abusive conditions, liquid may be ejected from the battery; avoid contact. If con-tact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
5.  Do not use a battery pack or tool that is dam-aged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
6.  Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or tem-perature above 130 °C may cause explosion.
7.  Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instruc-tions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Service

1.  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.

3.  Follow instruction for lubricating and chang-ing accessories.

Cordless recipro saw safety warnings

1.  Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wir-ing. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
2.  Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.
3.  Always use safety glasses or goggles. Ordinary eye or sun glasses are NOT safety glasses.
4.  Avoid cutting nails. Inspect workpiece for any nails and remove them before operation.
5.  Do not cut oversize workpiece.
6.  Check for the proper clearance beyond the workpiece before cutting so that the blade will not strike the floor, workbench, etc.
7.  Hold the tool firmly.
8.  Make sure the blade is not contacting the workpiece before the switch is turned on.
9.  Keep hands away from moving parts.
10.  Do not leave the tool running. Operate the tool only when hand-held.
11. Always switch off and wait for the blade to come to a complete stop before removing the blade from the workpiece.
12.  Do not touch the blade or the workpiece imme-diately after operation; they may be extremely hot and could burn your skin.
13.  Do not operate the tool at no-load unnecessarily.
14.  Always use the correct dust mask/respirator for the material and application you are work-ing with.
15.  Some material contains chemicals which may be toxic. Take caution to prevent dust inhala-tion and skin contact. Follow material supplier safety data.

Battery protection system

The tool is equipped with a battery protection system. This system automatically cuts off power to the motor to extend battery life. The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

Overloaded
The tool is operated in a manner that causes it to draw an abnormally high current. In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart. If the tool does not start, the battery is overheated. In this situation, let the battery cool before turning the tool on again.

Low battery voltage
The remaining battery capacity is too low and the tool will not operate. If you turn the tool on, the motor runs again but stops soon. In this situation, remove and recharge the battery.

Indicating the remaining battery capacity

Press the check button on the battery cartridge to indi-cate the remaining battery capacity. The indicator lamps light up for a few seconds.

NOTE: Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

Switch action

CAUTION: Before installing the battery car-tridge into the tool, always check to see that the switch lever/trigger actuates properly and returns to the “OFF” position when released.

To prevent the switch lever/trigger from accidentally pulled, the lock-off lever/button are provided. To start the tool, pull either switch lever or trigger.

•  For the switch lever, pull the lock-off lever and then pull the switch lever to start the tool.
   For the switch trigger, depress the lock-off button and then pull the switch trigger to start to the tool. The lock-off button can be pressed from either right or left.

Lighting up the front lamp

CAUTION: Do not look in the light or see the source of light directly.

Pull the switch lever/trigger to light up the lamp. The lamp keeps on lighting while the switch lever/trigger is being pulled. The lamp goes out approximately 10 seconds after releasing the switch lever/trigger.

NOTE: Use a dry cloth to wipe the dirt off the lens of the lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination.

Adjusting the shoe

When the blade loses its cutting efficiency in one place along its cutting edge, reposition the shoe to utilize a sharp, unused portion of its cutting edge. This will help to lengthen the life of the blade.To reposition the shoe, loosen the bolt with hex wrench. Slide the shoe to the desired position and then tighten the bolt firmly.

ASSEMBLY

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Installing or removing the recipro/jig saw blade
CAUTION: Always clean out all chips or for-eign matter adhering to the blade and around the blade clamp. Failure to do so may cause insufficient tightening of the blade, resulting in a serious injury.

Insert the recipro saw blade into the blade clamp as far as it will go. The blade clamp sleeve rotates and fixes the recipro saw blade. Make sure that the reciprocal saw blade cannot be extracted even though you try to pull it out.

CAUTION: If you do not insert the recipro saw blade deep enough, the recipro saw blade may be ejected unexpectedly during operation. To remove the recipro saw blade, rotate the blade clamp sleeve in the direction of the arrow fully. The recipro saw blade is removed and the blade clamp sleeve is fixed at the released position.

NOTE: If you remove the recipro saw blade without rotating the blade clamp sleeve fully, the sleeve may not be fixed. In this case, rotate the blade clamp sleeve fully, then make the sleeve fixed at the released position.

To install the recipro/jig saw blade, loosen the bolt by hex wrench. When installing a recipro saw blade, press the bolt with the hex wrench to open the slot during inserting the blade.
