MSW-FS-500
Make sure the unit is turned off (ignition switch is OFF).
Unscrew the cutter blade nut and remove the outer flange
holding it. The surface of the flange in contact with the blade
should be clean. Place the cutting disc on the axle, paying
attention to its direction in accordance with the direction of
rotation of the machine drive. Place the collar holding the
shield and the washer with the part sunk inwards (towards
the shield - see the picture below) and tighten them with
a nut.
PLEASE NOTE: use diamond blades adapted to working with
rotations higher than the maximum rotation of the machine
(see technical parameters tables) and adapted to water
cooling. When transporting the machine, the cutting disc
must be removed.

Engine oil
PLEASE NOTE: before starting the machine for the first time,
the engine oil should be topped up, as the machine is empty
during transport.
Always check the oil with the machine turned off and the
engine cold, or at least 5 minutes after the engine is turned
off. The machine should be placed in a horizontal position,
i.e. not tilted, on a flat, even surface. Unscrew the oil filler cap
and wipe clean its end which enters the hole, making sure
that no foreign objects get into the hole in the meantime.
Then, put the plug in the hole (without screwing it in) and
take it out after a few seconds, checking the oil level at the
plug tip. The engine oil should be in the range of the marked
part of the tip, i.e. between the "MAX" and "MIN" levels (see
image below). If it is not, top the oil up to the bottom edge of
the filler hole, and then check the level at the tip of the plug
again. Never exceed the maximum level and never allow
its level to drop below the minimum – there is a danger of
damaging the engine when it is running! Recommended oil:
SAE 10W30 for diesel 4-stroke engines (standard operating
conditions) or 5W30 (operation also in very cold weather),
API SJ class or newer.

The machine must be turned off while the engine oil is
replaced. Hot oil is thinner and drains faster, however, if
you want to change the oil right after the machine stopped
running, let it cool down (for several minutes).
PLEASE NOTE: the hot oil and its drainage area may be hot
–beware of burns!
(see picture below)
Place an oil-resistant vessel of appropriate capacity under
the drain plug, then unscrew the oil inlet plug first, and then
the drain plug and wait until the oil flows out completely.
Before replacing the drain plug, wipe off the oily area around
the engine housing as well as its thread. Tighten the plug
gently, do not tighten it as far as it will go, so as not to
crush its gasket - it may lose its tightness. If the drain plug
gasket is damaged/worn, it must be replaced. Pour fresh oil
through the filler plug to the correct level (see the previous
paragraph). Close the filler opening with the plug.
•
Fuel
PLEASE NOTE: you can refuel only with the engine off, in a
well-ventilated area, and away from sources of fire or sparks
which might potentially cause the fuel or its vapours to
ignite! When refuelling the machine, make sure not to spill
fuel on the hot parts.
Unscrew the cap on the top of the fuel tank and pour the fuel,
not exceeding the maximum level, i.e. to the limit of the neck
of the strainer in the tank inlet (see the picture below). To
power the machine, use only unleaded petrol (min. 95 RON
octanes) with ethanol/methanol content not exceeding 5%.
Fuel with the addition of methanol must contain additives:
co-solvents and corrosion inhibitors. It is not allowed to use
an oil/fuel mixture!

3.3. DEVICE USE
A.
Starting the machine
Open the fuel supply valve – switch the lever ON.
With a cold engine, move the hand choke lever to ON
(the valve is closed). If the engine is warm, leave the
choke lever in the OFF position (the valve is open).
Set the throttle lever to 1/3 of the scale length from
the slowest revolutions, i.e. at the turtle icon (in the
case of the MSW-FS-500 model, the throttle lever
is located on the machine control panel.) Set the
ignition switch to ON. Pull the starter cord - pull it
gently until you feel resistance, then pull firmly until
the engine starts (it may require several repetitions).
After the engine has started, do not let go of the cord,
but let it return slowly to its original position. When
starting cold, let the engine idle first in order to bring
it up to operating temperature - as the temperature
rises, gradually reduce choke by moving the choke
lever to the OFF position (the valve is open).
PLEASE NOTE: the water supply should be shut off
while the engine is warming up.
B.
Cutting
Mark a straight line on the floor/pavement along
which you are going to cut.
In the MSW-FS-350, start the engine with the cutting
blade raised. Turn on the water supply, increase the
engine speed to maximum.
Use the height adjustment knob to position the saw
blade so that it is in contact with the ground. Set the
desired cutting depth - each graduation of the scale
corresponds to 9.5 mm (3/8 inch). Lower the cutting
disc slowly towards the surface to be cut so as not to
stall the engine. Make a rough cut to a depth of 50
mm before reaching the desired cutting depth – it is
the so-called gradual cut. Slowly move the machine
forward, making sure that the guide blade is following
the marked line.
In the MSW-FS-500 model, in order to start cutting set
the maximum revolutions, and then lower the blade
to the desired cutting depth. Then, fix the desired
cutting depth using the height adjustment knob, and
lock it with the lever under the knob. Turn on the
water supply, lower the blade slowly, and proceed
to make the cut with maximum engine speed. Slowly
move the machine forward, making sure that the
guide blade is following the marked line. If the cutting
disc will not keep in the groove, reduce the speed with
which the machine is moved forward.

C.
Turning the machine off
•
Emergency shutdown - in an emergency, press the
emergency shutdown button on the left handlebar
(MSW-FS-350) or the red poppet on the control panel
(MSW-FS-500), the engine will stop immediately.
Close the water supply.
•
Normal shutdown - stop cutting and turn off water
supply. Move the throttle lever to the lowest speed
(the turtle icon) and let the machine run for a few
minutes. Then turn the ignition switch to the OFF
position. Close the fuel supply valve - the OFF position.
D.
Automatic shutdown of the machine
There may be several reasons why the machine will
stop running unexpectedly:
•
Wrong belt tension
•
No fuel
•
The machine is pushed forward too fast or the blade is
lowered too rapidly
In each of these cases, first release the blade from the
groove, turn off the machine (the switch in the OFF
position), turn off the water supply and check the
machine carefully for damage before continuing work.
3.4. CLEANING AND MAINTENANCE
a)
Unplug the mains plug and allow the device to cool
completely before each cleaning, adjustment or
replacement of accessories, or if the device is not
being used. Wait for the rotating elements to stop.
b)
Use only non-corrosive cleaners to clean the surface.
c)
Store the unit in a dry, cool place, free from moisture
and direct exposure to sunlight.
d)
Do not spray the device with a water jet or submerge
it in water.
e)
Do not allow water to get inside the device through
vents in the housing of the device.
f)
Clean the vents with a brush and compressed air.
g)
The device must be regularly inspected to check its
technical efficiency and spot any damage.
h)
Use a soft cloth for cleaning.
i)
Use a soft, damp cloth for cleaning.
j)
Do not use sharp and/or metal objects for cleaning
(e.g. a wire brush or a metal spatula) because they
may damage the surface material of the appliance.
k)
Check the engine oil level after each use, and top up
the bearing oil to the height adjustment mechanism.
l)
When the machine is not used for a long time, it is
recommended to drain the fuel (for more details, see
3.4.1 point F)
