15.3.1 CUTTING WITH CUTTING WHEEL LOWERED
FROM ABOVE.
Adjust the vertical height by turning the crank (ref.11, fig.1),
position the piece to be cut, start the panel saw and commence
cutting operations by pressing the pedal (ref.16, fig.1) to lower
the wheel from above.
15.3.2 BLADE CHANGE
To change the blade refer to section 14.
16. USING 550 DIAMETER CUTTING WHEEL.
If an optional cutting wheel diameter 550 mm is used instead of
the standard wheel diameter 500 mm, it is important that the
stop bolt be calibrated to prevent interference between the
wheel and the carriage when the head is in the lowest position.
- Warning. The panel saw is fitted with a stop bolt to
stop the cutting wheel in the lowest vertical position.
This stop is calibrated for a 500 mm cutting wheel. If
you are using a 550 mm cutting wheel, loosen the bolt
(ref. 17, fig. 1), lower the wheel to the lowest position, by
turning the crank, then check, with the motor turned
off, that there is no interference between the cutting
wheel and the piece holder carriage when the pedal is
pressed. Adjust the bolt, bring it into contact with the
stop and tighten the lock nut.
- Note that the blade must have an external diameter
of 550 mm, a central hole diameter of 25.4 mm and max.
thickness of 3 mm.
17. 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.
Do not leave the machine outside: it must always be protected
from the weather.
Below is a list of the cleaning operations that must be carried
out at the end of every shift.
17.1 TANK CLEANING
Empty the tank by removing the drain plug. Remove cutting
residue using a jet of water.
17.2 TANK REMOVAL (Ref.Fig.7).
Empty the drum opening the drum cap from right or left side.
17.3 WORK SURFACE CLEANING
Always keep work surfaces clean. Residual dirt can impair
cutting precision.
17.4 GUIDE RAIL CLEANING
It is good practice to remove all traces of dirt from the guides.
17.5 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.
– Check that there is water in the pump by unscrewing the connector,
and if necessary top up until water flows out (fig.10).
- WARNING. Before starting the panel saw for the first
time, or when starting it after long periods of inactivity, fill
the pump with water as described above
- At the end of every shift, unscrew the suction hose filter and clean
it. Then, circulate some water through it placing inside a bucket of
clean water.
17.5 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
17.6 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
17.7 DRIVE BELT REPLACEMENT
Repeat the operations described in section 17.6, replacing the
belt before tensioning it.
17.8 ENDOTHERMIC ENGINE MAINTENANCE
Refer to the specific instruction manual enclosed with the
endothermic engine for its correct routine maintenance.
17.9 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
