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.

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

• 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

• 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.
