- Check that the blade is aligned with the cutting line.
- Place the workpiece on the worktable (ref. 8, fig. 1), resting firmly
against the stop. Start the motor.
Wait until the water reaches the blade. Begin cutting.
- Horizontal cutting movement is carried out by pulling the carriage
towards the blade.
- 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
Bring the blade support to its highest position and lock. Position the
workpiece. 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 13.
16. MAINTENANCE
- WARNING! Servicing must always be carried out by
qualified technicians and only after the motor has been
switched off.
- Always keep the guards in proper working order
and free from damage. Take particular care to ensure
that the blade guards are kept efficient and clean,
replacing them if they are damaged.
- 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.
Never leave the machine out in the open. Make sure that it is
stored in a sheltered area away from extreme weather
conditions.
Below is a list of the cleaning operations that must be carried out
at the end of every shift.
16.1 TANK CLEANING ON WORK COMPLETION
- Empty the tank by removing the plug. Remove cutting residue
using a jet of water.
16.2 TANK REMOVAL (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
It is good practice to remove all traces of dirt from the guides.
16.5 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)
16.6 TENSIONING THE DRIVE BELT (fig. 8)
- Switch off the electric motor and remove the plug from the
power supply.
- Unscrew the 4 screws that secure the movable belt guard (ref. 1).
- Loosen the 4 (ref. 2) screws that clamp the electric motor to
the blade support.
- Tension the belt using the nut (ref. 3): apply a force of about
F=6 Kg to the centre of the free section of the belt, the arrow
should be about f=6 mm (fig. 9).
- Tighten the screws on the electric motor, checking the alignment
of the motor pulley and the blade pulley
- Refit the guard and lock it using the 4 screws.
- To avoid shortening the life of the belt, the bearings
and the blade shaft, do not overtension the belt. Finally,
check the two pulleys are aligned.
16.7 DRIVE BELT REPLACEMENT
Repeat the operations described in section 16.6, replacing the
belt before tensioning it
17. REPAIRS
- Do not start the saw during repair work.
Only use genuine IMER spare parts and do not modify them.
- If the guards are removed to carry out repairs, they
must be refitted properly when the repair work is finished.
18. TROUBLESHOOTING
- WARNING! Before carrying out any maintenance
operations, switch off the machine, and remove the plug
from the power socket.
FAULT
CAUSE

device has been
activated.
- Check power cables
- Ensure correct
connection
- Connect cable- re
-Connect wire
- Remake the
connection
- Replace switch
-Wait for a few minutes
and then try restarting
the machine.
