• Due to our continuing program of research and development, the specifications herein are subject to change without notice.
• Specifications may differ from country to country.
• Weight according to EPTA-Procedure 01/2003
ENE021-1
Intended use
The tool is intended for sawing wood, plastic, metal and
building materials with a strong impact. It is suitable for
straight and curved cutting.
ENF002-2
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. They
are double-insulated and can, therefore, also be used
from sockets without earth wire.
ENG905-1
Noise
The typical A-weighted noise level determined
according to EN60745:
Sound pressure level (LpA) : 88 dB (A)
Sound power level (LWA) : 99 dB (A)
Uncertainty (K) : 3 dB (A)
Wear ear protection
ENG900-1
Vibration
The vibration total value (tri-axial vector sum)
determined according to EN60745:
Work mode : cutting boards
Vibration emission (ah,B) : 15.0 m/s2
Uncertainty (K) : 2.0 m/s2
Work mode : cutting wooden beams
Vibration emission (ah,WB) : 20.0 m/s2
Uncertainty (K) : 2.5 m/s2
ENG901-1
• The declared vibration emission value has been
measured in accordance with the standard test
method and may be used for comparing one tool
with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
WARNING:
• The vibration emission during actual use of the
power tool can differ from the declared emission
value depending on the ways in which the tool is
used.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of
exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it
is running idle in addition to the trigger time).

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.
GEB008-6
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.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this
instruction manual may cause serious personal
injury.

FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function
on the tool.
Adjusting the shoe
Fig.1
Fig.2
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 "A" direction 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 "B" direction with a click.
Switch action
CAUTION:
• Before plugging in the tool, always check to see
that the switch trigger actuates properly and
returns to the "OFF" position when released.
• Switch can be locked in "ON" position for ease of
operator comfort during extended use. Apply
caution when locking tool in "ON" position and
maintain firm grasp on tool.
Fig.3
To start the tool, simply pull the switch trigger. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
For continuous operation, pull the switch trigger and
then push in the lock button, then release the switch
trigger.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
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.
Fig.4
To install the blade, loosen the screw on the blade
clamp with the hex wrench. Insert the blade between
the blade clamp and the slider so that the pin on the
slider fits into the hole in the blade shank. If the pin
cannot easily fit into the hole, remove the hex wrench
from the screw and then try again.
CAUTION:
• If you tighten the screw without the pin on the
slider fitting properly in the hole in the blade shank,
the pin or the blade shank will be damaged. This
may cause the blade to be extracted unexpectedly
during operation.
Fig.5
After the pin fits properly into the hole, tighten the screw
clockwise securely. Make sure that the blade cannot be
extracted even though you try to pull it out.
To remove the blade, follow the installation procedure in
reverse.
Hex wrench storage
Fig.6
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
OPERATION
CAUTION:
• Always hold the tool firmly with one hand on
insulation cover and the other on the switch
handle.
• Always press the shoe firmly against the
workpiece during operation. If the shoe is removed
or 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.
Fig.7
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.
• Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.
