GENERAL SAFETY RULES

WARNING! Read all instructions. Failure to follow all

instructions listed below may result in electric shock, fire and/or serious injury. The term "power tool" in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS.

Work area safety

1. Keep work area clean and well lit. Cluttered and

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.

Pipe 130 mm (5-1/8")

Wood 255 mm (10")

GEA001-3

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.

Personal Safety

9. 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.

10. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

11. Avoid accidental starting. Ensure the switch is in the off-position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

12. 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.

13. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

14. 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.

15. If devices are provided for the connection of

dust extraction and collection facilities, ensure these are connected and properly used.

Use of these devices can reduce dust-related hazards.

Power tool use and care

16. 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.

17. 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.

18. 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.

19. 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.

20. Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

21. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

22. Use the power tool, accessories and tool bits

etc. in accordance with these instructions and in the manner intended for the particular type of power tool, 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

23. 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.

24. Follow instruction for lubricating and

changing accessories.

25. Keep handles dry, clean and free from oil and grease.

GEB008-2

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to recipro saw safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Hold power tools by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Contact with a "live" wire

will make exposed metal parts of the tool "live" and shock the operator.

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.
