the worktable. Tighten the knob fully to lock into position.
To bring the blade back to the vertical position (pos.0) carry out the above
operations in reverse order.
Ensure that the locking knob (ref.1) is tightened fully before
starting work.
15.3 CUTTING
- Before cutting, check that the blade is aligned with the cutting
line.
- Place the workpiece on the worktable snugly against the fence.
- Start the motor and wait until the water reaches the blade to
begin cutting.
- Start cutting movement by pulling the carriage towards you
by means of the relative handle (ref.1 fig.6).
As cutting thickness increases, the blade is subjected to
greater stress. To avoid overloading the motor, the operator should
continually check blade feed speed. The speed will also depend on
the characteristics of the material being cut (hardness, toughness
etc.).
15.3.1 CUTS WITH BLADE LOWERED FROM ABOVE
(Ref. Fig.8)
Bring the blade support to its highest position and lock. Position the
workpiece on the worktable. Start the machine, unlock the blade support
and begin vertical cutting until the blade reaches its lowest point. Lock
the support once more and proceed with horizontal cutting.
15.3.2 BLADE CHANGE
To change the blade refer to section 14. BLADE INSTALLATION.
Do not use blades for wood or segmented disks with
slots wider than 5 mm.
16. MAINTENANCE
- WARNING!
Always switch the machine off and
remove the plug from the power socket before carrying out
any maintenance operations .
- Always check that the protective guards are in the
correct position and in perfect condition.
- As there is the continuous risk of inadvertent damage
to the electric cables, these must be checked regularly each
time before the machine is used.
-WARNING! If the electric motor or control panel
are removed for maintenance, it's necessary to replace
the relevant seals in order to guaranty the right degree
of protection and safety against water penetration inside
to the electric circuits.
Never leave the machine out in the open. Make sure that it is stored
in a sheltered area away from extreme weather conditions.
Replace worn or faulty components with original spare parts.
- WARNING! Recommend product for cleaning
and lubrificating the mechanical parts of the saw:
WD-40
16.1 TANK CLEANING ON WORK COMPLETION
On completion of work, empty the tank and remove. Clean
thoroughly to remove cutting residue.
16.2 TANK REMOVAL (Ref.Fig.7)
Lift the tank (ref.1) to detach from its supports (ref.2) and remove
from the side indicated by the arrow.
16.3 WORK SURFACE CLEANING
Always keep work surfaces clean. Residual dirt can impair cutting
precision.
16.4 GUIDE RAIL CLEANING
The horizontal guide elements on the carriage are protected against
dirt build-up by scrapers. However we advise thorough cleaning of
the guide rails to ensure correct operation.
WARNING! Do not use any type of lubricant on the
guide rail.

16.5 CARRIAGE CLEARANCE ADJUSTMENT (Ref. fig.9)
LATERAL ADJUSTMENT: turn adjustment screw 1 gradually
clockwise using a hex wrench no.3, so that the internal roller
comes into contact with the bar. Take care not to exert too much
pressure. Repeat the same operation with the other adjustment
screws according to the order indicated in the figure. Adjust
vertical clearance by means of the screws located on the lower
part of carriage (A). On completion, if carriage travel is not smooth,
slacken the adjustment screws by turning the wrench anti-
clockwise; if clearance has not been eliminated repeat the above
operation.
16.6 CLEANING AND MAINTENANCE OF COOLING CIRCUIT
- If water does not reach the blade stop the machine immediately to avoid
blade damage.
- After switching off the machine ensure that the water level is sufficient.
- If necessary, after disconnecting the machine from the power supply
check that the tap, hose and pump filter are not blocked
- If necessary, check that the impeller rotates freely (after extended periods
of disuse)
- If necessary, remove the pump and check that the pump/motor coupling
is in perfect condition.
16.7 DRIVE BELT REPLACEMENT
- Disconnect the machine from the power supply
- Remove the water hose connection by loosening the hose clamp on the
blade guard.
- Remove the blade, the two flanges, the blade half-guard securing screws,
the locking knob (ref.1, chart 02) and remove the blade external half-
guard (motor side).
- Remove the blade shaft with pulley from the bearing (ref.27, drawing 02)
and fit into the bearing of the half-guard previously removed (ref.14, chart
02).
- Fit the new belt onto the two pulleys and refit the belt tensioner.
- Refit the seal on the edge of the guard and ensure that it is in good
condition and that the two locating pins are in the correct position.
- Refit the guard inserting the blade shaft into the bearing (ref.27, chart
02) taking care to align the screw (ref.51, drawing 02) located on the slot
of the head fulcrum (ref.19, drawing 02) with the locking handle hole
(ref.1, drawing 02).
- Join the two blade half-guards using the two locating pins to align correctly.
- Screw in the two blade half-guards by tightening diagonally opposite
screws alternately.
- Screw in and tighten the locking handle before installing the blade.
17. TROUBLESHOOTING
N.B.: Before carrying out any maintenance operations,
switch off the machine, set the switch to 0 and remove the plug
from the power socket.
