Note the direction of rotation
indicated by an arrow on one
side of the disc (direction of
rotation shown on the outside of
the guard housing).
Check the state of cleanliness of
the disc support faces of the
adaptor plates (B and C) and of
the spindle.
The holding screw (D) of the disc
has a right-hand thread.
8Stopping the machine
• Turn the handwheel (K) to free the
disk from the groove [ SEE FIG. 4]
.
•No need to lock the saw up by
releasing the handwheel (K).
• Turn off the water supply (G).
• Allow the motor to run idle.
• Switch off the motor (refere to the motor
maintenance manual).
6Fitting the blade
• Place the machine in an high position.
• Make sure the engine is switched off.
.
•Unscrew the nuts (E) from the guard
housing [SEE FIG. 3].
• Remove the guard housing (A).
• Fit the diamond impregnated disc.
•Firmly tighten the screw (D) with the
spanner provided with the machine,
holding the disc steady by hand.
• Replace the protective guard (if this is not
replaced the casing safety switch will
prevent the saw being started).
• Reconnect the water hose (mains with
valve or tank).
• Tighten the nut (E).
Motor off
• Turn off the water tap (G)(from the mains
or from the tank in order to fill it) [SEE
FIG.x4].
• Mark out a line on the ground where a cut
has to be made.
• Position the machine so that the lowered
front guide (F) and the disc are aligned
with the line marked out (disc visble on
the belt side of the housing).
• Start up the motor : refer to the motor
manufacturer’s instructions in the service
manual.
• Allow the motor to warm up.
• Turn on the water supply tap (G) (from
the mains or the water tank).
• Increase the motor speed to full.
• Hold the saw, turn the handwheel (K)
and position the disk in contact with the
floor.
• Lower to the depth of cut required, and
bearing in mind that each graduation of
the scale corresponds to a depth of 1cm.
Lower slowly to prevent the engine
stalling.
•Gently move the machine forward
ensuring that the front guide and the disc
are always aligned with the line marked
out.
• After use, clean the machine.
• Lubrication : apply a moderate amount of
bearing lubricant to the nipples in the
depth adjustment chassis (depending on
the frequency of use).
•Model with petrol motor (refer to the
motor maintenance manual).
■Make sure the fuel is topped up.
■Check the oil level; as the motor often
works at an angle, check it frequently in
the horizontal position that the oil level
is never below the second line on the
gauge.
■To start up, refer to the motor
instructions.
Take into account the working
conditions from health and safety
point of wiew.
Use only blades marked with a
maximum operating speed
greater than blade shaft speed
"Engine Maintenance" : refer to
the engine maintenance booklet.
Dispose of the old oil as laid
down by the regulations in force.
Motor off
Emergency stop
Operate the switch (J) in front
of the engine.
Entrust repairs to authorised
dealer only
7Starting up
Always pay extreme care and
attention to the preparation of
the machine before starting up
Remove all adjustment tools and
wrenches from floor and
machine
Always keep blade guard in
place
Ensure that the water supply is
abundant, when cutting wet.
• There may be several causes responsible
for arresting the disc in the sawing groove
or stopping the machine:
■Belt tension.
■Lack of fuel.
■Advance or lowering too fast, etc.
•In all case, disengage the disc from the
groove and give the machine a complete
check-over.
9Incidents during sawing
The working area must be
completely cleared, well lit and
all safety hazards removed (no
water or dangerous objects in
the vicinity)
The operator must wear
protective clothing
appropriate to the work he
is doing. We recommend
that this includes both eye
and ear protection
Any persons not involved in the
work should leave the working
area
The use of ear protection is
mandatory.
5Check before starting
Please read the instructions for
use prior to operating the
machine for the first time.
Motor off.
• Check the engine oi l everyday. Refer to
the engine manual for oil change
schedule. Use :
■SAE 10W30 motor oil with API class
MS, SD, SE or better for PETROL
engines.
■API class CD or CE for Hatz diesel.
