The air lock is usually created in the diesel pump. The safest way to clear this is by firstly removing the silver pipe from the diesel pump, as well as the black rubber hose from the solenoid valve. The black rubber hose bring diesel from the tank to the diesel pump and the silver pipe transports the diesel to the engine. An air lock occurs when an air bubble prevents the plunger inside the pump to act as a diaphragm. The bubble resists the movement of the plunger which prevents diesel from being pumped through to the engine. Connect the ends of the two pipes together. By doing this, you have bypassed the diesel pump. Diesel will now flow directly into the silver pipe towards the injector. Reconnect the pipes as per the first picture. The air bubble will now be sucked through the system upon starting the generator. To start the generator, pull down on this decompression lever and turn the ignition. Make sure that the fuel tap is open. This is found just below the tank. When the generator starts you should let it run for +- 30 seconds before killing the engine. Refer to the next section if you experience any further problems. - The generator does not start after checking for an air lock. There could be two possibilities to this happening. There is a problem on either the solenoid valve or the diesel pump. Firstly, make sure that the fuel tap is open and that diesel reaches the solenoid valve. Disconnect the silver pipe from the diesel pump and start the machine. A working solenoid valve should allow a few drops of diesel to be squirted out from the diesel pump’s outlet. You should also hear a loud “click” sound as the magnet disengages the valve.
If none of these happen, first replace the solenoid valve before checking the diesel pump itself. - There is a “click”, but no boom, or squirting. It has happened in the past where the plunger mechanism in the diesel pump has rusted solid. To fix this, remove the diesel pump and spray Q20 or any anti-rust & lubricating agent onto the spring and plunger. Leave the pump for about half an hour to allow the Q20 to properly loosen the rust and lubricate all the parts. Take a rubber mallet and hit the bottom of the plunger until it moves freely again. Replace all the parts, connect the pipes and you should have a working generator. - Remember the oil sensor. The generator comes standard with an “oil level sensor”, of which the main function is to protect the engine when the oil level is too low. This is easily resolved by checking the dipstick, situated at the bottom of the sump, and adding oil. If the generator still does not start, unplug the yellow wire protruding from the side off the generator from the green wire. This is the oil sensor’s wire. Start the generator, and let it run for 5 minutes before reconnecting the two wires. The engine should cut out if the oil sensor is faulty. This is easily replaced with a new oil sensor, available from our spares department. It is very important that your generator is placed on a level area whilst in use, otherwise the oil sensor may not pick up that there is no oil in the sump. This may cause your engine to overheat and seize. - The engine is running, but there is no power output from the plugs. This generator comes standard with an AVR unit. What does this do? The AVR is best explained as follows. It can be seen as a tap with a fuse. Why a tap with a fuse? Just like a tap, the AVR “opens” to allow a certain amount of current through, for instance, if you need 2kw from a 4kw generator, the AVR will allow 2kw of power through. It does this by raising the engine’s revolutions enough so that the alternator supplies the needed power. When you turn the tool off, the AVR drops the engine’s revolutions to an idle. The AVR acts as a fuse when the demand for power is too high. Every generator can supply a maximum amount of power. The 4kw can give 4.5kw maximum. When you try and run a geyser, which may need 5kw, the AVR will burn out, cutting the supply from the alternator to the plugs. Excessive demands for power such as this may lead to the field coil windings burning. In these cases a rewind is needed, which is very costly. The AVR, which is available as a spare part, is replaced by removing the black cover from the alternator, and removing the banana shaped block. This is the AVR, and must be replaced when damaged. - Will a welding machine run from my generator? Looking at old technology welders, such as the oil bath type, the answer is definitely no. Traditional oil bath welders require large amounts of current, sometimes up to 40 amps, to function properly. This is much more than any of our petrol generators can supply. They also tend to cause power fluctuations as they only pull power when you weld. The generator will basically go from idling to full power, back to idling, back to full power, which will cause major damage to the motor and windings. - What about my inverter welder? We do not advise the using an inverter on any of the generators. The fluctuation in current causes damage to vital parts on the pc-boards. You will however, in case of an emergency, be able to run a 160 amp inverter on NO MORE THAN 90amps off the 5.5kw generator. - Using an extension on the generator. It is possible that you may need to use an extension from the generator. Please keep the following in mind. A Proper 2.5mm core extension must be used. Then, for every 10metres of length, there will be an approximate power loss of 500w – 600w (2.2amps – 2.7amps). Keep this in mind, especially when using lengths of up to 40m that will equal a loss of about 2000w.
