• SIDE BRUSH:
  The side brush, Detail 1 Fig. 5, acts as a conveyor of the dust and rubbish and is only used to clean edges, corners and borders; after these operations it has to be lifted up to avoid raising dust and also because the cleaning effect of the side brush is always less than that of the main broom.

• CENTRAL BRUSH:
  The main brush, Detail 2 Fig. 5 is the main part of the sweeper . This brush collects and loads dust and rubbish in the refuse container; it is available with diff erent types of bristles of diff erent harnesses according to the material to be collected; it can be adjusted in height when it is worn.
  IMPORTANT: Never collect string, wires, packaging straps, sticks etc., that are longer than 25 cm as they could wind around the side and main brushes.

• FILTERING SYSTEM:
  Thanks to the sweeper’s fi ltering eff ect no dust is seen in the environment when it is working. This is achieved by means of fi lters Detail 3 Fig. 5; the fi lter system can be disengaged by pulling the knob Detail 4 Fig. 6 upwards .
  IMPORTANT: Disengage the fi lter when going over damp surfaces (if the machine is running) otherwise the paper fi lters will get damp causing them to deteriorate quickly.

• DUST FLAPS:
  See Details 4 of Fig. 5. These fl aps are all around the main brush and are extremely important to ensure that the sweeper works properly thanks to their suction eff ect; check them often to make sure they are always in a good state of repair .

• REFUSE CONTAINER:
  The refuse collector or container Detail A Fig. 1, is made in strong and resistant plastic and holds all the material collected by the main brush and dust from the fi lters.
  IMPORTANT: Always empty the container after the motor has been turned off , wearing gloves and even a mask to protect your lungs from the dust which is always present in this operation.

• BATTERY CHARGER (only for SLG 700 ET):
  The battery charger (Detail 1 Fig. 5/B) is located on board the machine and can be accessed by lifting the central casing Detail 1 Fig. 4.

CHAPTER 10 – CHECKS PRIOR TO STARTING UP

SPECIFIC CHECKS FOR MODELS WITH ENDOTHERMIC ENGINES
**** Carefully read use and maintenance handbook for the motor, enclosed with the documentation supplied with the machine.

1. Check the oil level of the engine and top up if necessary (wear nitril safety gloves throughout the operation). For type of oil and amount, see indications in the handbook for the engine.
2. Fill up with petrol (with the engine off and cold, and using the type of fuel recommended by the manufacturer of the engine – see engine user handbook).

STORE THE FUEL IN A FRESH AIRY PLACE, AWAY FROM SOURCES OF HEAT AND OUT OF REACH OF CHILDREN.
IMPORTANT: The container used for storing the petrol must be suitable for this purpose and perfectly clean so as to avoid damage to the petrol fi lter caused by impurities. Use a petrol container of a capacity in proportion to the amount consumed, so that in a period of 2 – 3 months the fuel is all used in this way it will always be fresh.
SPECIFIC CHECK FOR MACHINES POWERED BY BATTERY
Acquire the following instruments and personal protections: Safety glasses, protective gloves, 1 pair of scissors, 1 receptable for the transfer (clean), 1 funnel (clean). Carefully read the chapter “Safety rules and regulations”, which specifi es the risks involved with filling the elements with the sulphuric acid solution
Check if the battery contains the sulphuric acid solution and if it is charged . If not, proceed as follows:

1. Use the scissors to cut off the end of the plastic container holding the sulphuric acid solution and pour it into the transfer container .
2.  Remove the cap to the chambers of the battery elements . With the aid of the funnel, pour in the solution until it reaches the level shown on the outside of the battery .
3.  Wait at least 12 hours leaving the battery inactive and then, if necessary, top up the solution bringing the levels, of the various elements to the same conditions .
4.  Carefully read, in the chapter “Safety rules and regulations”, the risks involved in charging or discharging the battery . Charge the battery .

CHAPTER 11 – STARTING AND STOPPING

STARTING THE MACHINE, IT IS INDISPENSABLE TO HAVE READ THE PREVIOUS CHAPTERS.
SPECIFIC SEQUENCE FOR MODELS WITH ENDOTHERMIC ENGINES
Consult the attached motor instructions booklet previous.

• STARTING:

1. When the engine is cold, pull the spring-loaded STARTER lever outwards to the CLOSED position (CHOKE SHUT).
2.  Move the accelerator lever upwards from the SLOW position towards the FAST position;
3.  Pull lightly on the starting handle until you feel some resistance, then pull forcefully . Gently push the starting handle back into position . Do not allow the knob of the cord to return forcefully and strike the engine . Slowly move it back into position to prevent damage to the start-up .
4.  Push the starter spring lever to the OPEN position (CHOKE OPEN) as soon as the engine has warmed up enough to run smoothly

• RUNNING:

1.  Once the engine is running return the accelerator lever to the low speed position “ SLOW “ and warm the engine for a few minutes . Gradually move the accelerator lever towards the high speed position until the required speed is reached .
   IMPORTANT: If there is no need to keep the engine accelerating, slow it down gradually by moving the accelerator lever to the idle running speed: this will reduce fuel consumption and prolong the engine life.

• TURNING THE ENGINE OFF:

1.  Move the accelerator lever to Minimum and keep the engine running for 30/40 seconds before turning it off .
2.  Lower the lever fully down to the “STOP” position . The engine will stop .
3. Once it has stopped, lift the accelerator lever slightly .

SPECIFIC SEQUENCE FOR BATTERY POWERED MODELS
• START:

1. Turn the key in the clockwise direction Detail 3 Fig. 6.

• STOP:

1. Turn the key in the anticlockwise direction, Detail 3 Fig. 6.

CHAPTER 12 – CORRECT USE AND ADVICE

IMPORTANT: Before starting the job, make sure that the surface to be swept is free of objects such as ropes, strips of plastic or metal, rags, stick, live electric cables or other similar articles. If such object are present, remove them to avoid damage to the machine or, in the case of live electric cables, risks of electrocution.

• Crossing over rails, small steps or guides which stick up from the fl oor can damage the flaps on the central brush vacuum chamber; this being one of the most frequent causes of damage, if such object have to be crossed, lift the front part of the machine at the moment of crossing by pressing down on the handle to gain leverage .
• Avoid crossing over wet or particular damp surfaces in order to avoid damage to the paper fi lters. 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 fi rst time to get rid of the majority of the dirt, then pass over a second time with the refuse container and the suction fi lters clean. If the machine is used methodically and correctly, it is not necessary to carry out multiple passes .
• 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 Detail 6 fi g. 6 . 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 Detail 1 fi g. 6 .
• To keep the machine effi cient and consequently obtain top performance, the vacuum fi lters must be shaken and cleaned periodically and the refuse container emptied frequently .
•  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 WHEN RECHARGING THE BATTERIES.

CHAPTER 13 – ROUTINE MAINTENANCE

**** ANY MAINTENANCE OPERATION MUST BE CARRIED OUT WITH THE ENGINE OFF AND COLD IN THE CASE OF ENDOTHERMIC VERSIONS OF THE MACHINE AND WITH THE BATTERY DISCONNECTED IN THE ELECTRIC VERSIONS.

• CLEANING THE DUST FILTER:
  Check the dust fi lter Detail 4 Fig. 8 every 40-70 working hours or as necessary . Open the cover Detail 1 Fig.1 to access the fi lter compartment.
  Cleaning the fi lter: with the bin Detail A Fig.1 in place, point the compressed air gun towards the top of the fi lter so that the dust falls into the bin. Make sure the fi lter is in good condition and replace it if necessary.

• DUST SEALS:
  Check the condition of the fl aps Detail 4 Fig. 9 every 40/70 hours. Damage or ineffi ciency of the fl aps jeopardises the performance of the machine in terms of cleaning quality
  IMPORTANT: To replace the side fl aps, 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 .

**** FOR ELECTRIC MACHINES, REMOVE THE BATTERIES BEFORE TILTING SO AS TO AVOID SPILLAGE OF THE SULPHURIC ACID SOLUTION.

ADJUSTMENTS
• CENTRE BRUSH:
To adjust the centre brush
If the machine removes dirt and debris ineffi ciently or leaves dirt behind, it needs to be adjust.
Lower the centre brush and proceed as follows:

1. Remove the protective case Detail 2 Fig.4
