GENERAL SAFETY RULES

GEA001-3

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.

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.

2

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.

SPECIFIC SAFETY RULES

GEB009-2

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 tool 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.Wear ear protectors.

3.Check the socket carefully for wear, cracks or damage before installation.

4.Hold the tool firmly.

5.Always be sure you have a firm footing.

Be sure no one is below when using the tool in high locations.

6.The proper fastening torque may differ depending upon the kind or size of the bolt. Check the torque with a torque wrench.

WARNING:

MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

CAUTION:

•Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

•Change the direction of rotation only when the tool comes to a complete stop. Changing it before the tool stops may damage the tool.

The switch is reversible, providing either clockwise or counterclockwise rotation. To start the tool, simply pull the lower part of the switch trigger for clockwise or the upper part for counterclockwise. Release the switch trigger to stop.

ASSEMBLY

CAUTION:

•Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

NOTE:

•Hold the tool pointed straight at the bolt or nut.

•Excessive fastening torque may damage the bolt/ nut or socket. Before starting your job, always perform a test operation to determine the proper fastening time for your bolt or nut.

The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1.Voltage

Voltage drop will cause a reduction in the fastening torque.

2.Socket

•Failure to use the correct size socket will cause a reduction in the fastening torque.

•A worn socket (wear on the hex end or square end) will cause a reduction in the fastening torque.

3.Bolt

•Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of bolt.

•Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt and the bolt length.

4.The use of the universal joint or the extension bar somewhat reduces the fastening force of the impact wrench. Compensate by fastening for a longer period of time.

5

5.The manner of holding the tool or the material of driving position to be fastened will affect the torque.

MAINTENANCE

CAUTION:

•Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

Replacing carbon brushes
