16. MAINTENANCE
- WARNING. . Servicing must always be carried out
by skilled personnel and only after the endothermic
engine has been turned 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.
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.
16.1 TANK CLEANING
Empty the tank by removing the drain plug. Remove cutting
residue using a jet of water.
16.2 TANK REMOVAL (Ref.Fig.7).
Empty the drum opening the drum cap from right or left side.
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.
– 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.
16.6 TENSIONING THE DRIVE BELT (fig. 8)
- Turn off the endothermic engine.
- Unscrew the 4 screws that lock the movable belt guard (ref. 1).
- Loosen the two screws (ref. 2) that clamp the water pump to the
bracket and move the pulley away so that it does not touch it.
- Loosen the 4 screws (ref. 3) that clamp the endothermic engine to
the blade support.
- Tension the belt using the nut (ref. 4): apply a force of about F=2.5 Kg
to the centre of the free section of the belt, the arrow should be about
f=10 mm (fig. 9).
- Tighten the screws on the endothermic engine, checking the alignment
of the engine pulley and the blade pulley
- Lower the water pump until the pulley touches the drive belt. Tighten
the two screws.
- 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 15.6, replacing the
belt before tensioning it.
16.8 ENDOTHERMIC ENGINE MAINTENANCE
Refer to the specific instruction manual enclosed with the
endothermic engine for its correct routine maintenance.
16.9 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.
