Undoubtedly one of the most commonly asked questions put to us, the ‘how do I look after my Giuliano Tyre Machine’ request is one we actually love to answer. In any garage, it is a very real but very unfortunate fact that the tyre fitting machine can be the least considered item of equipment when it comes to love and care.
Lifts are a bit more ‘in your face’; you are working under them, there is more of an onus in terms of insurance and Health and Safety, and people just seem more conscious of the need to service vehicle lifts. Similarly, diagnostics products often have to be routinely looked at because maybe they are an MOT item like a gas analyser, or need regular updates and/or calibration. A tyre machine, however, can all too often be neglected.
So, when someone asks ‘what should I be doing?’, it is music to our ears. There is no doubting the positive effect routine maintenance can have to the life and reliability of a tyre changing machine. It is a complex collection of mechanical components, including pneumatic components that will always need some kind of attention.
Of course, the simplest and, arguably, the most sensible way to look after this investment is to use the supplier to attend on a 6 or even 12 monthly basis. It is easy to forget that your own time is not free, and sometimes it is better value to pay an expert to do what they do every single day and are vastly experienced in, and put your own efforts to more productive use. At Giuliano Automotive we have specialist tyre equipment technicians who know tyre fitting and removal products inside out, top to bottom, and they will often spot things before they happen. However, it is fair to say that everyone who owns a tyre machine is going to be mechanically minded, so given some guidance there really is no reason the maintenance and servicing can’t be done in-house.
We know lost of tyre shops who make it an official part of the job; a routine check that can be alternated between employees. A simple check sheet laminated and cable-tied to the machine with instructions for someone to follow is worth its weight in gold when you take into account the return simply through longer life, before we even talk about better performance and reduced cost of ownership. We even have some of our larger customers, who own multiple machines, allocate a tyre machine each to a specific tyre technician, and it then becomes their responsibility to take care of that product. Before you know it, there becomes a competitive element as to whose machine is the shiniest and best looked after!
What we have done here is provide a list of simple, routine actions you can take to ensure you get the very best of from your investment. From the size of the list, you will see it really is minimal, but these actions will make a huge difference and you will get the very best from your Giuliano Tyre Changing Machine.
Before we get to those actions, let’s take a look at the effect and positive consequences of giving some ‘TLC’ to what is often an overlooked, overworked and, dare we say, often abused tool in the workshop.
Life Expectancy
There are so many moving parts in a tyre changer that all interact with each other, that if one element of that is allowed to slip, it can rapidly affect the deterioration of the other vital components, as well as compromising the ability to do its job as it should.
Performance
Following on from the point above, if parts are allowed to wear, become loose, become dry, or even start to break, it can seriously affect the performance of the machine, I.e. the ability for the tyre changer to do its job, which is to fit and remove tyres in complete safety.
We know this from machines that are ‘retired’ because they are, for example, damaging wheels. Many would consider the machine having had its day, and this may be the case if its been allowed to go too far. However, we have seen on so many occasions a customer say that their machine is damaging wheels and they think they may need a new one, only for one of our technician to adjust and tighten two grub screws on the demount head (the little tool that sits against the rim, often also called a ‘duckhead’ for obvious reasons), and it results in an instant ‘cure’. “It’s like a new machine”, is an oft-heard statement once one of the Giuliano tyre machine experts has worked on a well-worn tyre changer.
Safety
When we talk about safety, this is two-fold. Firstly, we talk about the rim and tyre. A machine with too much ‘movement’ from slack that has developed, which could be as a result of a worn hinge / pivot pin, a loose demount head, or a loose vertical pin on the bead breaker (the list is endless) can easily scratch alloy rims and rip tyres. At this point, all hell breaks loose because there is a soon-to-be unhappy customer in the waiting room, an unhappy business owner, a deflated tyre technician, and a member of the Giuliano service team that is probably going to get the brunt of it because it’s “the machine’s fault” and, well let’s face it, it has just become a very bad day. The consequential cost makes the time taken to service the machine, or even pay for a Giuliano engineer to visit, seems like a drop in the ocean.
The other safety aspect is that of the operator. Anyone who has ever seen the result of someone who has trapped their fingers in the machine because a clamping cylinder has allowed to become increasingly loose will know the value of keeping everything tight and secure! We live in a litigious world, allowing for any opportunity for an employee injury is essentially negligence, and then we open a whole new can of worms!
So now that we have discussed the merits of routine service and maintenance of your Giuliano Tyre Machine, and the downsides of not doing it, let’s look at the very simple, short, but valuable list of checks you can make.
To add even more perspective, we have added some detail as to the purpose and point of each particular element.
Print this off, laminate it, make it part of the working week, and even stick a copy in the personnel files signed by your employees if you want to be super vigilant. However you implement it, just know you are adding immense value and life to your Giuliano Tyre Fitting Machine.
Task / Item | Explanation | What To Do | Frequency |
Oiler (Lubricating Bowl) | Most lube bowls are located on the side or at the back of the machine. This incredibly vital component will ensure the lubrication of all moving parts within the machine, including seals contained within the various pneumatic cylinders that feature on all tyre changers | Unscrew the ‘bowl’ (be careful if it is tight, if you use mole grips or similar you risk causing damage), and fill with a standard, thin air tool oil. You can then adjust the ‘flow’ or drip of that oil into the machine by pressing the bead breaker and ensuring a drop of oil is released. If it isn’t flowing, or is flowing too fast, simply adjust the screw at the top of the bowl. | Every 2 weeks to every 2 months (dependent on volume of use) |
Water Trap | Most machines should contain another bowl, next to the lubricator, which collects water and prevents it getting into the machine. If you have a compressor with a built in ‘dryer’, this won’t be such a risk, but it is still worth checking periodically. Water ingress will prematurely damage the bead breaker cylinder first, and subsequently damage other components | Unscrew the bowl and release the water | This is very subjective dependent on the environment. A nice modern workshop with a built in dryer from the compressor and insulated building could probably be checked annually. However, a very busy tyre shop, in an old building with lots of humidity and basic compressor needs to be checked daily |
Bead Breaker Arm Piston Rod bolt and nut | These do come loose with use, and it is normally quite obvious as the bead breaker arm becomes to ‘droop’. It isn’t healthy as it affects the angle the bead is broken at (which is very specifically set) and then just results in more pressure on the machine and more attempts to break the bead by the operator. Eventually the hole that the pin goes through will start to wear into an oval and, at that point, it become a completely new bead breaker arm if you’re lucky. If you aren’t lucky, it may have damaged the bead breaker cylinder due to the misaligned piston rod as a result. | Simply go to the pin at the back of the bead breaker arm where it meets the bracket welded to the chassis, and tighten | Again, it is a visual check more than anything to determine if it needs doing, but it does no harm to tighten once a month even if there is no obvious drooping of the arm |
Demount Head or ‘Duckhead’ | This part is crucial as it comes into contact with the rim, or rather it shouldn’t if set up properly. It you set it too far away, it can stretch the bead of the tyre and put strain on other components. If it is too close it can scratch the rim. If the bolt underneath is loose it can eventually fall out, normally during the removal process and can cause serious damage. | There are normally, sometimes 4, grubscrews located to the front and/or rear of the head, and these will visibly adjust the head to the rim. You need to set the head against the rim so it is locked, and make these adjustments until you see approx. 2-3 mm clearance between the head and the rim edge. Underneath there is a bolt to tighten that secures the head to the vertical arm. | Once again, this is volume related, and really it is common sense to visually check, but there is no harm in doing this every week. |
Turntable | The turntable is a hugely integral part of the process and operation and it is important it is maintained to ensure the clamps remain concentric and that the cylinders underneath aren’t damaged | Ensure the turntable is cleaned with a good degreasing agent, and visually check to make sure there are no valves or wheel weights stuck in any of the components or spaces around the turntable area. Also ensure that the carriages holding the clamping cylinders are tight, and that the bolts holding the clamping jaws are secure | We would suggest every 2 weeks |
Drive Belt | Inside the chassis there is an easily seen and located drive belt coming from the motor pulley, this obviously impacts the effectiveness of the turntable rotation as well as noise and vibration | Simply adjust the belt tension until it feels taught. It doesn’t need to be measured or forced, just as long as there is no slack | Every month |
