procedure and can be used to compare one power tool with another.
The indicated amount of vibration emitted can also be used to do a preliminary check
of interruptions.
Warning:
During actual use of a power tool, depending on how the tool is being used, the amount
of vibration emitted may be different from the amount specified. To protect the user, it
is necessary to establish safety measures based on the assessment of interruptions in
the course of real use (in this context, all the stages in the operating cycle should be
considered, such as the periods of time in which the tool is switched off and the time in
which it is on but is operating without a load).
Reduce the amount of noise and vibrations as much as possible
- Use only suitable power tools.
- Clean and maintain the power tool regularly.
- Adapt your work method based on the power tool.
- Do not overload the tool.
- Have the tool checked by a professional whenever necessary.
- Disconnect the tool from the mains when not in use.
6. BEFORE USING FOR THE FIRST TIME
6.1 Unpacking
1. Open the box and carefully remove the tool.
2. Remove the packing material.
3. Remove the packing protection and transport materials (as applicable).
4. Check to make sure the box contains all the parts.
5. Check the tool and accessories to determine if it was damaged during transport.
6. If possible, keep the box until the warranty has expired. Then dispose of the box
while respecting the environment by taking it to a recycling centre.
WARNING
Neither the tool nor the packaging material is a toy. Children should not play with
plastic bags, aluminium sheets or small parts, because they could choke on or
swallow small parts.
6.2 Important Observations
a) Before plugging the tool into the mains, make sure the information on the product
identification label complies with the specifications of the power source.
b) While it is operating, the tool should always have a dust extractor attached through
the dust extraction hose.
WARNING
Always unplug the tool before making any adjustments to it.
6.3 Adjusting the Cutting Depth (SEE FIGURE 6.3)
The cutting depth can be changed by adjusting the lever.
a) Loosen the adjustment screw (3) and move the depth lever until the front end of the
lever is on the mark of the depth scale you want (Figure 2). The even millimetre values
on the depth scale are indicated with long lines and the odd values with short lines.
b) Tighten the adjusting lever again.
Observations:
1. For optimum results when cutting wood, select a cutting depth that is greater than
the thickness of the material.
2. To cut plastic, select a cutting depth that is greater than the thickness of the material.
If the material begins to melt, this problem can usually be cleared up by increasing
the cutting depth.
3. For optimum results when cutting metal, the cutting depth should be at least 1.0 mm
greater than the thickness of the material.
4. When cutting wood or plastic, the cutting depth can be adjusted to the exact
thickness of the material so that the surface below is not damaged. However, when
this procedure is used, the bottom of the work piece may not be completely clean.
6.4 Dust Extraction
WARNING
Working with some kinds of wood and metal or with paint that contains lead can
generate harmful or toxic gases that are a risk for the user and other people in
the work area. Always wear suitable personal protection and keep people from
getting too close to the work area.
Extracting dust is very helpful for keeping the work area clean because a great deal of
dust is produced when working with this power tool.
Because the cutting blade is almost completely enclosed in the saw body, extracting
dust is particularly effective in this case. A dust extractor or vacuum cleaner can be
attached to the hose (14), which is in turn attached to the connector for the dust
extraction device.
a) Unplug the tool and attach the hose to the connector for the dust extraction device (8).
b) Use a flange to attach the hose.
c) Check to make sure the blade guard moves freely. Use a cone-shaped adapter to
connect the hose to a dust extractor or a vacuum cleaner. If necessary, wrap duct tape
around the hose for added strength.
Observations:
1. Make sure that the extractor can be used with a power tool. Most dry and wet
household vacuum cleaners can be used.
2. Using a dust extractor is very practical when making several cuts one after another
because it reduces the need to stop as often to clean the tool and the work area.
3. Always use a dust extractor when cutting materials that generate dust that can
be harmful, such as certain kinds of wood flooring, medium-density fibre board and
ceramic.
7. OPERATION / START-UP
With this tool, the material to be cut is held between the base plate and the support
surface. The blade penetrates into the material to make a clean cut that is faster
and safer.
7.1 Turning On and Off
a) Slide the ON/OFF switch (4) forward to turn on the tool. The device will be
operating whenever the switch is moved forward.
b) To turn off the power, slide the switch to the OFF position.
7.2 Working with the Mini Circular Hand Saw (SEE FIGURE 7.2)
a) Select the right blade for the material you are going to cut.
b) Make sure the blade is sharp and in good condition.
c) Adjust the blade to the desired cutting depth (see Section 6.3).
d) Place the work piece you want to cut on a table, workbench or any other suitable
surface and hold it in place with clamps or a vice. Place sufficient scrap material under
the work piece so you do not make cuts in the support surface or break the blade due
to contact with the hard support surface such as a concrete floor.
e) Hold the power tool in your hand in a comfortable position. Your thumb or index
finger should be resting on the ON/OFF switch (4). Make sure your hand does not
cover the ventilation holes (6) on the front or back of the device.
f) Place the base plate (1) on the work piece. To leave a gap from the work piece,
place the saw so the back part of the base plate sticks out. Do not let the saw blade
penetrate into the work piece yet.
g) Turn on the tool and wait a few seconds until the blade is moving at the operating
speed. Press the lever for releasing the blade guard (12) and allow the blade to slowly
penetrate into the work piece while applying some pressure.
h) Move the tool forward while you cut through the work piece.
Never move the tool backward while the blade is in the work piece.
i) Do not apply great force when cutting with the tool. Applying too much pressure
creates wear and can tire you unnecessarily.
j) Make sure the base plate (1) is always flat on the work piece. This is particularly
important when cutting narrow bars that are not completely covered by the base plate.
7.3 Cutting Along a Line (SEE FIGURE 7.3)
Using the indicator on the front and rear of the blade guard makes it easier to cut
along a straight line.
7.4 Plunge Cutting (SEE FIGURE 7.4)
It is sometimes impossible to make plunge cuts in certain very hard materials.
a) Adjust the cutting depth (see Section 6.3), connect the tool to the power source
and place the base plate on the work piece. Make sure the depth setting on the side
is the same for all cuts.
b) Turn on the tool and wait two seconds until the blade is spinning at the working
speed. Then allow the blade to slowly penetrate into the work piece while applying
some pressure. Move the tool forward while you cut through the work piece. Never
move the tool backward while the blade is in the work piece.
c) When you reach the end of the cut, turn off the saw and take it out of the work
piece.
7.5 Cutting Difficult Materials and Materials that Create a Lot of Dust
Before trying to cut difficult materials, you should familiarize yourself with how the
tool works by cutting wood. To cut hard materials like metal and some plastics, more
pressure has to be applied from above.
WARNING! Never cut a material that generates dust or dangerous fumes when
working, such as some plastics and materials that contain asbestos.
Sheet Metal
a) Adjust the cutting depth so it is at least 1 mm greater than the thickness of the
material. Always place scrap material under the work piece.
b) Eliminate any deep scratches and rusty areas from the surface of the material,
since they make it much more difficult to move the tool forward.
c) After every 2 minutes spent cutting metal, you should stop for at least a 3-minute break.
Observation: Use suitable cutting fluid if necessary.
Floor tiles, slate and similar materials
a) Always use the right cutting blades for this job.
b) Always connect the tool to a suitable dust extractor. The dust generated during
cutting can be hazardous to the health and clog the blade guard.
c) Place adhesive or duct tape on the base plate to facilitate cutting and prevent
any scratching.
