Connecting devices to the generator’s 230 V outlets
Note:
• Only devices labelled as operating on 230 V, 50 Hz must be connected to thegenerator. Do not use
the 230 V and 12 V outlets at thesame time, i.e., do not run 230 V appliances whilst simultaneously
charging a12 V battery.
• The generator’s rated running output wattage is 2600 W under continuous operation, and its maximum
intermittent or surge wattage (for short bursts of extra power for starting appliances such as refrigerators)
is 3000 W.
• The total running wattage of theelectrical devices connected to thegenerator should not exceed 2600 W.
1. Make sure that all electrical devices are switched off before they are connected to thegenerator.
2. Set theAC on/off switch (17) to ON.
3. Switch on theconnected electrical devices in order of their wattage requirement. Begin with thedevice that
requires themost power.
Note: The AC on/off switch also acts as anovervoltage safety cut-off switch and trips if theload of theelectrical
devices becomes too high. Reduce theload and allow thegenerator to rest for awhile before loading it again.
12 V outlet
Note:
• The 12 V outlet is only intended for charging lead-acid batteries (car batteries).
• The charging current varies according to theengine speed and load. The maximum charging current is 8 A.
• Battery charging must be supervised and discontinued manually otherwise there is arisk of thebattery fluid
boiling and damaging thebattery. Whilst abattery is being charged it will emit anexplosive oxyhydrogen gas
mixture. Batteries should be charged in well-ventilated areas, and well away from sources of ignition.
• For more efficient car battery charging, we recommend that a230 V AC car battery charger is connected to
the230 V AC outlet of thegenerator.
• Do not connect batteries with capacities lower than 60 Ah.
• The 12 V outlet is unregulated, i.e. theoutput voltage depends on thespeed of theengine and theload on
thegenerator.
• The overvoltage safety cut-off (20) will trip if theload from theconnected 12 V device becomes too high. If this
happens, disconnect thebattery and investigate thecause. Press thereset button in to reset theovervoltage
safety cut-off protection. Allow thegenerator to rest for afew minutes before it is put under load again.
1. Connect thesupplied cable to the12 V outlet socket. It can only be connected one way, so there is no risk
of reversed polarity.
2. Connect theclamps to thebattery terminals.
Note: Ensure that thered cable clamp is connected to thepositive battery terminal and theblack cable clamp
to thenegative terminal.
Switching the generator off
1. Turn off all connected electrical devices and then unplug them from thegenerator.
2. Set theAC on/off switch (17) to OFF.
3. Let theengine run for afew minutes to stabilize thetemperature of thegenerator.
4. Set theengine on/off switch to 0 OFF.
5. Turn thefuel cut-off valve to OFF.
Care and maintenance
• The exterior of thegenerator should be cleaned using adamp cloth. Only use mild cleaning agents,
never solvents or corrosive chemicals.
• If thegenerator is not to be used for along time, empty thefuel tank, start thegenerator and run it on
the fuel remaining in thecarburettor until it runs out of fuel. This ensures that thefuel does not become
aged during storage. Petrol which has been left in thecarburettor during prolonged storage can lead to
starting problems.
