5. Avoid body contact with earthed or  
grounded surfaces such as pipes, radia-  
tors, ranges and refrigerators. There is an  
increased risk of electric shock if your body is  
earthed or grounded.  
ter control of the power tool in unexpected sit-  
uations.  
14. Dress properly. Do not wear loose cloth-  
ing 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  
conditions. 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 cor-  
rect 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 out-  
door 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 adjust-  
ments, changing accessories, or storing  
power tools. Such preventive safety mea-  
sures reduce the risk of starting the power  
tool accidentally.  
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 con-  
ditions will reduce personal injuries.  
19. Store idle power tools out of the reach of  
children and do not allow persons unfa-  
miliar with the power tool or these instruc-  
tions to operate the power tool. Power  
tools are dangerous in the hands of untrained  
users.  
11. Avoid accidental starting. Ensure the  
switch is in the off-position before plug-  
ging in. Carrying power tools with your finger  
on the switch or plugging in power tools that  
have the switch on invites accidents.  
20. Maintain power tools. Check for misalign-  
ment or binding of moving parts, break-  
age 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.  
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 bet-  
21. Keep cutting tools sharp and clean. Prop-  
erly maintained cutting tools with sharp cut-  
3
ting edges are less likely to bind and are  
easier to control.  
for operations different from those intended  
could result in a hazardous situation.  
22. Use the power tool, accessories and tool  
bits etc. in accordance with these instruc-  
tions 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  
Service  
23. Have your power tool serviced by a quali-  
fied repair person using only identical  
replacement parts. This will ensure that the  
safety of the power tool is maintained.  
- WARNING- To reduce the risk of injury, user must read instruction manual.  
ADDITIONAL SAFETY RULES FOR TOOL  
GEB008-1  
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 tool by insulated gripping sur-  
faces when performing an operation  
where the cutting tool may contact hidden  
wiring or its own cord.  
7. Hold the tool firmly.  
8. Make sure the blade is not contacting the  
workpiece before the switch is turned on.  
Contact with a “live” wire will make exposed  
metal parts of the tool “live” and shock the  
operator.  
9. Keep hands away from moving parts.  
10. Do not leave the tool running. Operate the  
tool only when hand-held.  
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.  
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.  
3. Always use safety glasses or goggles.  
Ordinary eye or sun glasses are NOT  
safety glasses.  
13. Do not operate the tool at no-load unnec-  
essarily.  
4. Avoid cutting nails. Inspect workpiece for  
any nails and remove them before opera-  
tion.  
14. Always use the correct dust mask/respira-  
tor for the material and application you  
are working with.  
5. Do not cut oversize workpiece.  
15. Some material contains chemicals which  
may be toxic. Take caution to prevent dust  
inhalation and skin contact. Follow mate-  
rial supplier safety data.  
6. Check for the proper clearance beyond  
the workpiece before cutting so that the  
blade will not strike the floor, workbench,  
etc.

Adjusting the shoe  
When the blade loses its cutting efficiency in one place along  
its cutting edge, reposition the shoe to utilize a sharp, unused  
portion of its cutting edge. This will help to lengthen the life of  
the blade. To reposition the shoe, push the shoe button in the  
Adirection with a click and reposition as shown in the figure  
which allows you to make five-way adjustment. To secure the  
shoe, push the shoe button in the Bdirection with a click.

Installing or removing the saw blade  
CAUTION:  
Always clean out all chips or foreign matter adhering to  
the blade, blade clamp and/or slider. Failure to do so  
may cause insufficient tightening of the blade, resulting  
in a serious injury.

OPERATION  
CAUTION:  
Always press the shoe firmly against the workpiece  
during operation. If the shoe is held away from the  
workpiece during operation, strong vibration and/or  
twisting will be produced, causing the blade to snap  
dangerously.  
Always wear gloves to protect your hands from hot flying  
chips when cutting metal.  
Be sure to always wear suitable eye protection which  
conforms with current national standards.  
Always use a suitable coolant (cutting oil) when cutting  
metal. Failure to do so will cause premature blade wear.  
005790  
Press the shoe firmly against the workpiece. Do not allow the  
tool to bounce. Bring the blade into light contact with the  
workpiece. First, make a pilot groove using a slower speed.  
Then use a faster speed to continue cutting.  
MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before attempting to perform inspection or  
maintenance.

WARNING  
Some dust created by power sanding, sawing, grinding, drilling, and other  
construction activities contains chemicals known to the State of California  
to cause cancer, birth defects or other reproductive harm. Some examples  
of these chemicals are:  
lead from lead-based paints,  
crystalline silica from bricks and cement and other masonry products, and  
arsenic and chromium from chemically-treated lumber.  
Your risk from these exposures varies, depending on how often you do this  
type of work. To reduce your exposure to these chemicals: work in a well  
ventilated area, and work with approved safety equipment, such as those  
dust masks that are specially designed to filter out microscopic particles.
