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.
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
atmospheres, 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
4. 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.
5. 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.
6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
7. 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.
8. 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.
9. 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.
10. Use of power supply via a RCD with a rated
residual current of 30mA or less is always recommended.
Personal safety
11. 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.
12. 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.
13. 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.
14. 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.
15. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
16.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing, and gloves away from moving parts.
3
Loose clothes, jewellery
or long hair can be caught in moving parts.
17.
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.
Power tool use and care
18. 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.
19. 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.
20. 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.
21. 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.
22.
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.
23. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
24. 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.
Service
25. 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.
26. Follow instruction for lubricating and
changing accessories.
27. Keep handles dry, clean and free from oil and grease.
RECIPRO SAW SAFETY WARNINGS
1. Hold power tool by insulated gripping
surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. 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 work 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
immediately 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 working with.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
SAVE THESE INSTRUCTIONS.
