WARNING:  
For your personal safety, READ and UNDERSTAND before using.  
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.  
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  
10. Use safety equipment. Always wear eye protec-  
tion. Safety equipment such as dust mask, non-skid  
safety shoes, hard hat, or hearing protection used  
for appropriate conditions will reduce personal inju-  
ries.  
1. Keep work area clean and well lit. Cluttered and  
dark areas invite accidents.  
2. Do not operate power tools in explosive atmos-  
pheres, such as in the presence of flammable  
liquids, gases or dust. Power tools create sparks  
which may ignite the dust or fumes.  
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 plug-  
ging in power tools that have the switch on invites  
accidents.  
3. Keep children and bystanders away while oper-  
ating a power tool. Distractions can cause you to  
lose control.  
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.  
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.  
13. Do not overreach. Keep proper footing and bal-  
ance at all times. This enables better control of the  
power tool in unexpected situations.  
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.  
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.  
6. Do not expose power tools to rain or wet condi-  
tions. Water entering a power tool will increase the  
risk of electric shock.  
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.  
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.  
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.  
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.  
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.  
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.  
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 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.  
the manner intended for the particular type of  
power tool, taking into account the working con-  
ditions and the work to be performed. Use of the  
power tool for operations different from those  
intended could result in a hazardous situation.  
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.  
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  
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.  
accessories.  
25. Keep handles dry, clean and free from oil and  
grease.  
22. Use the power tool, accessories and tool bits  
etc. in accordance with these instructions and in  
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 tool by insulated gripping surfaces when  
performing an operation where the cutting tool  
may contact hidden wiring or its own cord. Con-  
tact with a “live” wire will make exposed metal parts  
of tool “live” and shock the operator.  
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 depend-  
ing upon the kind or size of the bolt. Check the  
torque with a torque wrench.  
2. Wear ear protectors.  
3. Check the socket carefully for wear, cracks or  
damage before installation.

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

The proper fastening torque may differ depending upon the kind or size of the  
bolt, the material of the workpiece to be fastened, etc. The relation between  
fastening torque and fastening time is shown in the figures.  
Standard bolt  
Hold the tool firmly and place the socket over the bolt or nut. Turn the tool on  
and fasten for the proper fastening time.

NOTE:  
When fastening screw M10 or smaller, carefully adjust pressure on the  
switch so that the screw is not damaged.  
M16

Hold the tool pointed straight at the bolt or nut without applying excessive  
pressure on the tool.

If you fasten the bolt for a time longer than shown in the figures, the bolt  
or the socket may be overstressed, damaged, etc. Before starting your  
job, always perform a test operation to determine the proper fastening  
time for your bolt. Especially for the bolt over than M10, perform the  
above test operation to prevent the trouble on socket or bolt, etc.

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.

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.  
Fastening time (S)  
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. 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.
