      Hi Aaron. We are a privately owned and managed business. All our stores are privately held and run by head office. We do not offer any franchise stores at this stage.

      Hi Deon. To our knowledge, we have not ever seen a small enough jackhammer that can run of a smaller backup petrol generator like the one above. For remote work or roadwork, professionals tend to use pneumatic jackhammers powered by a larger commercial mobile air compressor (screw type). These generators are intended for backup use at home for a few hours at a time when load-shedding or municipality power is offline.

    I need to get a generator for emergencies when load shedding becomes a reality. To keep the fridges x3 and freezer, electric garage doors , gate and security SYSTEM (after back up battery is used up) to be kept in working order. What generator do you recommend? Price ? Where will I get the best deal?
    Thanks Estelle

      Hi there. We recommend measuring your draw by an electrician but going by what you mentioned a 5kw machine would do the trick. They start off at R7695 inc VAT. All our stores have the same pricing so you are welcome at any store of your choosing.

    Good day,
    I have 2 questions regarding running a generator dry.
    1. How often should you do this?
    2. Is there a procedure to start the generator again after a dry run as all fuel has been drained after the tap.

    • Francois Landsberg says:

      Hi, this only applies to petrol fuel engines. We recommend doing this after it seems machine might be stored or if power has been reliable for a few weeks. Don’t let it stand idle for more than a month. Starting it up again is the same as every other time just make take a few seconds or try longer since fresh fuel needs to flow from the tank into the carburetor.

      The gel-like residue petrol turns into when sitting idle in the carb happens after some time between 3 – 6 months.

      If you can run it dry every time go ahead, but load shedding is here to stay so you will probably need the machine daily.

    Hey Francois,

    I’m no expert so just wanted to know if I’m able to run my mig welder from a generator and if so, what specs am I looking for in the entry level generator for such purposes?

      Please contact our spares dept on 011 434 7000 There are different taps for different models but they are not expensive.

    Hi….My 5.5KW Generator was working properly…suddenly it stops running, i thought the was no fuel, then i top up, there after if it couldn’t start at all. instead it back fires all the time. what could be the problem…the generator is only 2 months old.

    • Francois Landsberg says:

      We suspect 1 of 2 things. The most likely is the fuel tap is shut off or it might be flooded (choke engaged for too long). Or the carburettor has become clogged due to petrol staying inside for too long. We can easily clean the carburettor. Visit your nearest store with the machine if you are having troubles they will very likely be able to check that fro you.

    I Have a diesel generator Model: JDP6000-LDENS. Something happened and now the 12vdc is missing, so as long as the battery is charged it will start, what could be wrong and the cost???

    • Sewes le Roux says:

      Hi Jannie

      The battery regulator is faulty so you need to replace it and needs new battery. You can get from any battery center, the regulator is R 695.00 and available from Adendorff.

    Good day
    I need to run three jumping castle motors of 0.75kv. Which size generator should I have in order to run three motors as the same time.

    • Sewes le Roux says:

      Good day Wooda

      You would need atleast a 5KW Generator to run the 3 jumping castles at the same time. Remember each electronic device needs atleast 3x the normal power to start up.

    I lost the instruction manual for my MacAfric chainsaw. Could you please tell me what is the ratio in which I have to mix the two-stroke oil with fuel.
    The two-stroke oil was supplied by Adendorff’s.

    My Generator just will not start. I bought the generator in Aug ’20. When i first wanted to use it in Sept’20 it would not start.
    The first time I took it back they told me it is the spark plug and i had to buy a new one and this is suppose to be a new generator.

    Took it home and it would still not start and had to take it back to the shop for the 2nd time that they.
    The guys fiddle with it for an hour and then it was working. It worked fine that night and a week after that.

    My problem i did not start the it every month and now it will not start at all. I topped it up with fuel and it just dont want to budge.

    What can i do to get it started?

    • Francois Landsberg says:

      This is a very common issue the reason the plug had to be changed is because of the shelf life of petrol. The machine after running still has some petrol inside the tap and carburettor. After some time for 3 – 4 months, this petrol becomes less fluent. It tends to make the carburettor dirty and will not start no matter what. After running the machine you must close the fuel tap while running so all petrol is cleared from the system. The technician can clean this out for you. There is most likely nothing wrong with the machine.

        Hi Francois Landsberg

        I took the generator over the weekend and the problem end up being the spark plug.
        Now my question is, I bought a spark plug in Nov and the same day we used the generator for 2 hours.
        Why was the spark plug the problem if only used once?

  10. Eltino says:

    Thank you for the reply Francois.
    Just making sure you are saying that I can take the machine to your shop in Aeroton and the technician can sort it out for me?
