Switching on and off the jig saw
You should make sure that at the work place the surface is even, stable and free of pollution.
Adopt a stable stand.
Grab the tool by the handle. You should not rest any parts of the working tools on any subject or object.
Press the switch with your finger and hold it. Check whether the saw blade is moving freely, and the tool does not suspiciously or
excessively vibrate, it is not emitting smoke or a strange smell. If you notice any deviations from the correct operation, you should
turn off the tool, remove the plug from the mains and take the tool to an authorized repair point.
The switch is equipped with a lock, which can be used during long-lasting cutting. When the switch is pressed down, you should
move the lock button to the left or right. Releasing the lock occurs when the switch is pressed.
The tool is stopped after possible unlocking and releasing the pressure on the switch. After switching off, the saw blade can move
for some time.
Cutting in a straight line
Before you start cutting it is recommended that you mark the cut line, for example by using a pencil. You should also make sure
that the cut material does not contain items of different hardness. For example, cut the wood should not contain nails, staples and
other metal items. You should also avoid the electrical wires, that may be hidden in the cut material.
Rest the tool base front on the cut material so the saw blade is not touching it.
Turn on the tool and let the saw blade achieve full adjusted speed.
Start cutting by leading the jigsaw with your both hands. During cutting you should press the saw to the surface and, at the same
time, by a smooth motion lead it along the cutting line. Use the minimum pressure which allows for the correct operation. Avoid
tilting the jigsaw, hitting by the blade in the crossing material and changes in direction of the cut. Failure to follow these instruc-
tions may lead to jamming of the saw blade in the cut material, damage or destruction (cracks) blade or cut material, as well as
to damage of the jigsaw itself.
During cutting a hard metal, for example a steel, your should use frequent breaks to cool the saw blade.
Cutting the curved line
You should comply with all the recommendations as in the case of cutting in a straight line, but you should use the saw blades
which are designed to cut arcs. They have a narrower blade than the saw blades designed for straight cutting and they make it
easier to cut arcs.
In the case of cutting holes, you should mark the shape of the cut hole, and then, at its edge, drill a hole with a diameter larger
than the width of the cutting blade. Drilled hole wall should be touching the line of the marked hole, which will be cut. In the hole
you should insert the saw blade of the jig saw and start cutting.
Additional notes
Do not allow to overload the tool, its external surface temperature should never exceed 60 C.
O
At the end of work you should turn off the tool, remove the plug from the mains socket, and make maintenance and inspection.
The declared, total value of vibrations was measured by using a standard test methods and can be used for comparison
of one tool with the other. The declared, Declared total value of vibration can was used in a preliminary assessment of exposure.
Attention! The vibration emissions when working with the tool can differ from the declared value, depending on how you use the
tool.
Attention! You should specify the security measures to protect the operator, which are based on an assessment of exposure in
the actual
conditions of operation (including in it all parts of the work cycle, such as, for example, the time when the tool is turned off or it is
idling, and its activation time).
MAINTENANCE AND OVERHAUL
ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been
finished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following
elements: body and handle, conductor with a plug and deflection, functioning of the electric switch, patency of ventilation slots,
sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee
period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee
rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service
shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be
cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or
cleaning liquids. Tools and handles must be cleansed with a clean cloth.
