Chapter 13 Routine Maintenance Jobs - Lavorwash SWL 700 ET Manuel D'instruction

Avoid crossing over wet or particular damp surfaces in order to avoid damage to the paper filters. In cases of strict necessity,
before crossing stop suction pulling the lever Detail 4 Fig. 6.
If the area to be cleaned is very dirty owing to the quantity and quality of the dirt to be eliminated, it is advisable to pass over
the first time to get rid of the majority of the dirt, then pass over a second time with the refuse container and the suction
filters clean.
If the machine is used methodically and correctly, it is not necessary to carry out multiple passes.
To keep the machine efficient and consequently obtain top performance, the vacuum filters must be shaken and cleaned
periodically and the refuse container emptied frequently.
The side brush is used for removing dirt from edges, skirting, corners, etc. and therefore it should be kept in the raised
position when it is not carrying out this function. If it is left on the ground, it will raise dust and in this case, the cleaning
power of the central brush will be jeopardised.
For the use in small spaces or for moving round close curves, it is advisable not to use the mechanical traction so that the
machine is easier to manoeuvre.
For battery powered machines, keep a close check on the condition of the battery and recharge it as soon as the needle on the
volt meter moves onto the red zone.
NEVER LET THE BATTERIES RUN COMPLETELY FLAT AND ALWAYS LET THE BATTERY CHARGER RUN A FULL CYCLE
_________________________________________________________________________________________
ANY MAINTENANCE OPERATION MUST BE CARRIED OUT WITH THE ENGINE OFF AND
COLD IN THE CASE OF ENDOTHERMIC VERSIONS OF THE MACHINE (GIOIA 50 ST AND
GIOIA 70 ST) AND WITH THE BATTERY DISCONNECTED IN THE ELECTRIC VERSIONS
(GIOIA 51 ET AND GIOIA 71 ET).

CLEANING THE DUST FILTER:
Check the dust filter Detail 1 Fig. 8 every 40-70 working hours or as necessary. Open the cover Detail 1 Fig.1 to access the
filter compartment.
Cleaning the filter: with the bin Detail A Fig.1 in place, point the compressed air gun towards the top of the filter so that the
dust falls into the bin. Make sure the filter is in good condition and replace it if necessary.
DUST SEALS:
Check the condition of the flaps every 40/70 hours. Damage or inefficiency of the flaps jeopardises the performance of the
machine in terms of cleaning quality, Detail 4 Fig. 6.
IMPORTANT: To replace the side flaps, make sure that their lower edge is 2-3 mm from the ground.
SIDE BRUSH:
Detail 1 Fig. 9. Keep raised from the ground when not in use to avoid raising dust unnecessarily. Keep raised from the
ground when the machine is not in use and make sure it does not come into contact with other objects which could bend it
making it unserviceable.
CENTRE BRUSH:
To clean the centre brush.
The following implements are necessary for carrying out this operation: heavy duty gloves, breathing mask, pliers, scissors
Check the condition of the central brush every 50/80 running hours, or more frequently if the machine is used for particularly
heavy duties. To gain visual access to the central brush, remove the refuse container (Detail A Fig. 1) and tip the machine as
shown in Fig. 9, by pressing down the handle.
If any ropes, wires or other refuse of this type has been inadvertently collected up, wear the heavy duty gloves and the
protective mask to eliminate any refuse that has been wound in the brush.
