11. ELECTRICALCONNECTION
/\- Ensurethatthere is an overloadcutoutdevice
fitted up-lineon thepowerline.
-Ensurethatthe mains
voltagecorresponds tothat
specified
forthemachine: 230V/6OHz.Theelectrical power
cable must
be suitably
sizedtoavoid voltagedrops. Cable drumsmustnot
be used.
Connect the machine toan efficient earthing system.
Thesize ofthepower cablewiresmustbe based onoperating
current and length ofthe power line to prevent excessive
voltagedrops (ref.Table 3).
Cables used on construction sitesmustbefittedwith suitable
external sheathing thatis resistant to wear, crushing and
extremeweatherconditions (forexample HO7RN-F).
/\-Allpowersupply installationsmust complywith
CEI 64-8 standards(harmonised
documentCENELEC
HD384).
12.MACHINESTART-UP
Before connecting the machine tothe power supply:
1 -Ensurethatthe metal structure isconnected toanearthing
plantasindicated in Section 7 "Safety Precautions".
2-Ensurethat thetank contains sufficient cooling water.
3-Ensurethatthe
power
circuitcorresponds tothe
requirements
asindicated in Section 11 "Electrical connections"
4-Connect themachine tothe power supply
5-Pressthe black switch (Ref. 7, fig. 1).
/\-Ifrotating direction isopposite tothe arrowon the
guard, stopthe machine andreverse the two

6-adjusttheflowofcooling waterbyturning thecocknext to
the blade guard(do notperform cutting without
water).
7-Check thatthedirection ofbladerotation corresponds tothat
indicated by
thearrowonthe blade guard.
8-Ifallisin order, proceed with cutting.
13.EMERGENCYSTOP

15.USE
/\-Leaveaspace of5ft.around themachine toopera-
te in fullsafety.
-Do notallowotherpersons toapproach themachine during
cutting.
-Neverusethemachine infire-riskareas. Sparks cancausefire
or explosions.
-Makesurethat themachine isswitched offbefore positioning
orhandling.
-Alwaysensurethat the bladeisfree ofany contactbefore
start-up.
-Ensurecorrectinstallation ofallprotective devices.
Before starting work, fill thewatertank.
Top upduring operation
whenevernecessary: NB. the pumpsuction hosemust
alwaysremain immersed in water.
-Insert theplug in thepower socket.
- WARNING! Forsafety purposes the removal of
protective
guards
fromthemachine isstrictlyprohibited
The machine is protected against overload: this
protection triggers stopping the machine, afterwhich
thetime necessary
fortheoverloadtocool mustpass
before itispossible
torestartthe machine.

15.1 VERTICAL MOVEMENT OFTHEDISK.
Toraiseorlower the
cutting wheel, turnthecrank
(ref.11,fig.1)
until thewheel is attherequired height above the
cutting table.
Thewheel canalsobe lowered bypressing the pedal (ref.16,
fig.1); when thepedal isreleased thecutting wheel willreturn to
theposition originally setusing thecrank.
/?\-Ensure that the lockinghandle is tightenedfully
before
starting work.
15.2POSITIONING FOR45°CUTS.
To machine a45° cut, it isnecessary tousethe45° support.
Placethe45°

fixthesupport
tothecarriage bylocking theflywheel provided,
then positionthepiecetobecut,
afterwhich itis possibletostart
themotorandcommence cutting operations
15.3 CUTTING
Forsafe useofthe machine when cutting, pushthe carriage
forwards asthe cut advances, placingyour hands tothetwo
sidesofthecarriage. Never
pushdirectly onthepiecetobecut.
-Checkthat the bladeisalignedwith the cutting
line.
-Place the workpiece on the worktable (ref. 8,fig. 1), resting
firmly against
thestop.
-Starttheengine.
-Waituntilthewaterreachestheblade.
-Begin cutting.
-
Horizontalcuttingmovement iscarriedout
bypullingthe
carriage
towards the blade.
-
Ascutting
thickness
increases,thebladeissubjected
togreater
stress. Toavoid overloading
theengine, the
operator should
continually
checkbladefeed speed. The
speedwillalso depend
on the characteristicsofthe
material being
cut(hardness, toughness etc.).
