GENERAL POWER TOOL SAFETY

WARNING
Read all safety warnings, instructions, illustrations and specifi cations provided with this power tool.
Failure to follow all instructions listed below may result in electric shock, fi re 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 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 fl ammable 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.
     Unmodifi ed 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 infl uence 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 a 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 fi nger 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 and clothing 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 remove the battery pack, if detachable, 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 and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aff ect the power toolʼs 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.

CORDLESS RECIPROCATING SAW

SAFETY WARNINGS

1. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring.
   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.

ADDITIONAL SAFETY WARNINGS

1. Preparing and checking the work environment. Make sure that the work site meets all the conditions laid forth in the precautions.

2. Do not allow foreign matter to enter the hole for connecting the rechargeable battery.

3. Never disassemble the rechargeable battery and charger.

4. Never short-circuit the rechargeable battery. Shortcircuiting the battery will cause a great electric current and overheat. It results in burn or damage to the battery.

5. Do not dispose of the battery in fi re. If the battery is burnt, it may explode.

6. Bring the battery to the shop from which it was purchased as soon as the post-charging battery life becomes too short for practical use. Do not dispose of the exhausted battery.

7. Do not insert object into the air ventilation slots of the charger. Inserting metal objects or infl ammables into the charger air ventilation slots will result in electrical shock hazard or damaged charger.

8. When using this unit continuously, the unit may overheat, leading to damage in the motor and switch. Therefore, whenever the housing becomes hot, give the saw a break for a while.

9. If the machine is used continuously at low speed, an extra load is applied to the motor which can result in motor seizure. Always operate the power tool so that the blade is not caught by the material during operation. Always adjust the blade speed to enable smooth cutting.

10. Always hold the body handle and front cover of the power tool fi rmly as shown in Fig. 14. Otherwise the counterforce produced may result in inaccurate and even dangerous operation.

11. Mounting and dismounting the blade

    • Pull the back of the saw blade two or three times by hand and check that the blade is securely mounted. When pulling the blade, you will know it is properly mounted if it clicks and the lever moves slightly. (Fig. 7)
    • When pulling the saw blade, be absolutely sure to pull it from the back. Pulling other parts of the blade will result in an injury.
    • Never touch the saw blade immediately after use. The metal is hot and can easily burn your skin.
    • If the broken saw blade is hidden inside the small slit, hook the broken blade using a tip of another saw blade and take it out. (Fig. 8)
    • After use, blow away sawdust, earth, sand, moisture, etc., with air or brush them away with a brush, etc., to ensure that the blade mount can function smoothly.
    • Do not use any saw blade with a worn-out blade hole. Otherwise, the saw blade can come off , resulting in personal injury.

12. Make sure that the battery is installed firmly. If it is at all loose it could come off and cause an accident.

13. Do not fi x and secure the switch lock. Besides, keep your fi nger off the switch trigger when the tool is being carried around. Otherwise, the main body switch can be inadvertently turned ON, resulting in unexpected accidents.

14. Be careful not to let sawdust, earth, moisture, etc., enter the inside of the machine through the plunger section during operation. If sawdust and the like accumulate in the plunger section, always clean it before use.

15. Do not remove the front cover which will cause in an injury.
    Be sure to hold the body from the top of the front cover.

16. During use, press the base fi rmly against the workpiece.

17. Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke quantity should be larger than the material.
    If you cut a large pipe, large block of wood, etc., that exceeds the cutting capacity of a blade; there is a risk that the blade may contact with the inner wall of the pipe, wood, etc., resulting in damage. (Fig. 10)

18. Never apply any unreasonable force to the saw blade when cutting. Doing so can easily break the blade.

19. The motor can be locked sometimes, depending on the combination of the material to be cut and the blade. Whenever the motor gets locked, switch it off immediately.

20. Use clamps or another practical way to secure and support the workpiece to a stable platform. (Fig. 11) Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

21. When cutting metallic materials, use an appropriate cutting fl uid (spindle oil, soapy water, etc.) to prolong the bladeʼs service life.

22. Delay the feed speed when cutting the material into small circular arcs. An unreasonably fast feed may break the blade.

23. Plunge cutting

    • Avoid plunge cutting for metallic materials. This can easily damage the blade.
    • Never pull the switch trigger while the tip of the saw blade tip is pressed against the material. If you do so, the blade can easily be damaged when it collides with the material.
    • Make absolutely sure that you cut slowly while holding the body fi rmly. If you apply any unreasonable force to the saw blade during the cutting operation, the blade can easily be damaged.

24. Keep the light ON during cutting operation only. If it is lit ON in other cases, the main body switch can be inadvertently turned ON, resulting in unexpected accidents.

25. Do not expose directly your eye to the light by looking into the light.
    If your eye is continuously exposed to the light, your eye will be hurt.

26. Never touch moving parts.
    Never place your hands, fi ngers or other body parts near the tool’s moving parts.

27. Never operate without all guards in place.
    Never operate this tool without all guards or safety features in place and in proper working order. If maintenance or servicing requires the removal of a guard or safety feature, be sure to replace the guard or safety feature before resuming operation of the tool.

28. NEVER leave tool running unattended. Turn power off . Don’t leave tool until it comes to a complete stop.

29. The power tool is equipped with a temperature protection circuit to protect the motor. Continuous work may cause the temperature of the unit to rise, activating the temperature protection circuit and automatically stopping operation. If this happens, allow the power tool to cool before resuming use.

30. Do not give a strong shock to the switch panel or break it. It may lead to a trouble.

31. Do not use the product if the tool or the battery terminals (battery mount) are deformed.
