STARTING AND STOPPING OF THE MOTOR (FIG. E)
Make sure that all the parts have been fitted properly, check the solidity of the assembly
and the machine's stability.
STARTING THE MOTOR
WARNING! Do not connect any appliance to the sockets before starting the gene-
rator. Place the power supply switch on "OFF" (9).
1. Open the petrol cock, lever in "ON" position (1).
2. Move the motor ON/OFF switch to "ON" (5).
For models with electric start-up, turn the key to 'ON' (5).
3. Place the air valve lever in the closed position (4).
4. Pull the start handle until there is resistance and then forcefully pull in the direction of
the arrow (7). For models with electric start-up, you can start the motor as indicated
in point 4 or: After installing the battery (previously charged) as indicated in the
chapter entitled 'battery assembly', turn the key to 'START' (10).
WARNING! This precaution is necessary to prevent injury due to sudden inversion
of the motor's rotation direction.
WARNING! Do not release the handle suddenly. Accompany it to its original
position.
5. After approximately 30", place the air valve lever on "OPEN" (3).
SHUTDOWN OF THE MOTOR IN THE CASE OF LOW MOTOR OIL (where fitted)
WARNING! The motor is equipped with a device for automatic emergency shutdown
of the motor if there is not enough oil. This device prevents serious damage to
the motor. If the device intervenes, check and replenish to the correct level (see
previous chapters).
STOPPING THE MOTOR
1. Move the power supply switch to "OFF" (9, where fitted) and disconnect all of the
plugs from the sockets.
2. Move the motor ON/OFF switch/key to "STOP" (6).
3. Close the petrol cock, lever in "OFF" position (2).

USE OF THE GENERATOR

WARNING! before connecting any electric load, be sure you fully understand the
safety regulations stated above.
WARNING! The load is applied after the motor has been started.
WARNING! The load connected to the generator must never exceed the PRP supplied
power indicated in the technical data.
WARNING! Observe the maximum current indicated on each socket.
WARNING! The alternator has a trip switch to protect against overloads. In the case of an
excessive load, it could intervene to protect the alternator. If the trip switch intervenes,
reduce the applied load and reset (where fitted, Fig. A no.29 and 31, Fig. A no.10)
WARNING! Pay attention to the power factor of your load.
Always calculate the absorption of the load to be applied to the generator before-
hand.
Guidelines for the type of load that may be applied to the generator are shown
below.
Note: For the generator's power, refer to the technical data label.
For the powers of the connected appliances, refer to the power consumption indicated
on their technical data labels.
100% of the generator's PRP
Examples of load:
- Purely resistive loads with cos ϕ= 1
- Incandescent luminaries
- Electric heaters with resistance
- Electric geysers
- Clothes irons
65% of the generator's PRP
Loads with high starting power and power factor near 1.
Examples of load:
- Power tools with universal motors (brush)
- Angle grinders
- Portable jigsaws
- Portable circular saws
- Heat guns
50% of the generator's PRP
Loads with high starting power and power factor other than 1.
Examples of load:
- Asynchronous motors
- Compressors
- Hoists
- Concrete mixers
- Fluorescent lights
20% of the generator's PRP
Loads with very high starting power
Examples of load:
- Refrigerators
- Air conditioners
USE OF AN EXTENSION CAbLE
Extension cables must be chosen carefully. Refer to the related safety regulations.
To prevent excessive drops in voltage, use cables that are an adequate size for the
load.

CONNECTING THE LOAD (FIG. E)
1. Connect a suitable plug, coming from the appliance, to the generator's socket.
2. Place the power switch on "ON" (8) (where fitted).
WARNING! The load must always be disconnected before turning off the motor.
Disconnecting the load
1. Place the power switch on "OFF" (9) (where fitted).
2. Remove the plugs from the sockets.
USING THE bATTERY CHARGER (IF PRESENT)
WARNING! Non-observance of the correct procedures for charging the battery could
cause damage to the latter and explosion.
WARNING! Follow the special instructions for charging the battery supplied with the
latter.
WARNING!! The generator's 12V socket is to be used exclusively as a battery char-
ger.
WARNING! Do not use the 230V socket together with the 12V socket.
WARNING! During charging, batteries emit hydrogen, which is highly inflammable. Char-
ge in well-ventilated places away from flames, lit cigarettes and all types of sparks.
WARNING! The generator supplies current sufficient for charging batteries up to 70
Ah/ 12V.
The generator is equipped with a fuse near the 12V socket.
Charging the battery
1. Start the generator.
2. Connect the generator's positive pole (red) to the battery's positive pole.
3. Connect the generator's negative pole (black) to the battery's negative pole.
4. Leave the battery connected until it is fully charged.
5. Disconnect the positive pole from the generator.
6. Disconnect the negative pole from the generator.
7. Turn off the generator.
MAINTENANCE (FIG. F)
WARNING! Each operation indicated below must be carried out while the motor
is off, the power switch is on "STOP" (Fig. E, Pos. 6) and the load's plug is di-
sconnected.
WARNING! If in doubt, contact an authorised assistance centre.
WARNING! Contact an authorised assistance centre for any operations not included
below.
Cleaning after every use
Take care of your machine and clean it regularly to ensure that it remains perfectly
efficient and has a long lifetime.
Clean the machine using a soft brush or cloth.
Do not spray or soak the machine with water.
Do not use inflammable substances, detergents or solvents as these may damage the
machine beyond repair. The plastic parts are prone to damage by chemical agents.
Replacing the motor oil
Check the oil level before each start and top up if necessary.
Replace the oil after the first month or after the first 20 hours of use. Then replace it
every 6 months or after every 80 hours of use.
See the previous chapters.
Spark plug
Check it after every 50 hours of use, and replace it if necessary.
See the technical data in reference to the spark plug type.
1. Remove the pipette and unscrew the spark plug using the relative spanner.
2. Examine the spark plug and remove any carbon residue with a metal brush. Replace
the spark plug if the electrode is excessively worn or the insulation is damaged.
3. Measure the distance between the electrodes: it should be between 0.7 and 0.8
mm (fig. M2).
4. Screw the spark plug back in by hand.
5. Secure a used spark plug with around ¼ turn of the spanner, and a new one with
around ½ turn of the spanner.
Air filter
Clean it after every 50 hours of use, and replace it if necessary.
If used in dusty environments, clean more frequently.
1. Open the cover of the filter box (Fig. A, part 15).
2. Remove the sponge.
3. Wash it with soap and water and rinse completely.
4. Leave it to dry.
5. Immerse the sponge in clean motor oil.
6. Squeeze it to remove excess oil. If there is too much oil left in the sponge, the
motor could smoke.
7. Place the cover of the box and the relative seal back into position.
