With the gradually development of the times and the continuously technological progress, it has been a general trend that the machines in weighbridge will replace human to do the manual works, and in the current market, there are a lot of machineries such as the concrete laser screeds, among which the holding volume of the two-wheeled walk behind concrete laser screeds is in a relatively larger number. The service life of this machine has quite an important relationship with the maintenance for the machine itself, so the latter maintenance for this machine is quite important. And the two-wheeled concrete walk behind laser screed has an obviously overall advantages and enjoys a convenient latter repair and maintenance service, and now I will make a couple of points about the daily maintenance for the two-wheeled walk behind concrete laser screed.
- Before the start of the two-wheeled walk-behind laser screed, the staffs must make a thorough inspection for this machine in order to find if there are damages in the machine components, or if the screws in the key parts are loosed, or if there are damages in the whole vehicle circuits, or if there is enough fuel in the fuel tank. Problems should be found and resolved in advance so that a project delay and a project postponement can be avoid, it shall select trained professionals to operate this machine, it shall not casually assign personnels or machines to do the work, and it shall reasonably, rightly and normatively operate this machine in accordance with the technical manuals and the guidance from the professionals, so that a few unnecessary damages can be avoided, and practice has proven that man-made operations are accountable for most of the machine failures.
- After the start of the two-wheeled walk-behind laser screed, an overloaded operation at low temperatures shall be prevented, and the normal operation during the low-speed pre-heating period shall be assured, so that the machinery can be runned or operated after reaching its set-point of temperature, and those mentioned above have played the vital role in the operation of machine so you shall not ignore the important role played by them because no problems happened at that time, pre-heating at low temperature is quite important to the engine, and pre-heating at low temperature has exactly direct relationship with the service life of its engine, so it shall not make the machine have an overloaded operation. And the even(steady) adds or subtracts for the load of this machine shall be assured, so that the load of this machine can be changed in a mild way, specifically speaking, to throttle up or down the engine evenly is quite important so that a radical change in its engine or some radical movements made by its working devices can be prevented, if an excess temperature were found or an machinery breakdown occurred, it shall stop using this machine immediately, so that the expansion of the machine malfunction can be avoid, and the vehicle shall be stopped for inspection immediately so that the fault can be found and timely resolved, then an source expansion of the machinery malfunction can be avoid. Some severely machinery failures are usually caused by some relatively smaller machinery failures, neglecting to make a timely resolution for smaller failures is the root cause, so, no matter big or small, the machinery failures shall be fixed timely so that the machine can keep its normal performance, and the possibility of incurring a bigger machinery faults can be avoid.
- After the working of the two-wheeled walk-behind laser screed, it should firstly clean the machine, that is to say you should clean up the concrete stains in order to keep its accuracy, then you should smear the machine oil on its key parts such as the screed head and the wheel hub(machine oil). Check out the laser receiver to see if the electric quantity in the smaller receiver is full, if not, you need to charge the battery timely, you must place the laser transmitter and the laser receiver safely, and you must be sure to remember that you need to handle them with care.
- Normal maintenance, the two-wheeled laser screed has adopted the Honda GX200 engine, and the first maintenance for this machine should be made when the the time of the instrument pointer reaches 50 hours, then it should be maintained every other 100 hours, and the oil change should choose the air-cooling four-stroke machine oil, after replacing the machine oil filter, you should check if there are obstacles in the engine fan, clean them up if there were, so that a good heat dissipation can be assured.
- During the time of using the two-wheeled laser screed, the rubber mat in the front of the screed head may get damaged and deformed during the process of rubbing and squeezing, so keep a close eye on it and replace it timely.
All in all, for the machine, we must maintain a machine reasonably, rightly and timely. Only by accomplishing those points mentioned above can the service life of these two two-wheeled walk behind concrete laser screeds owned by you get prolonged, then the machinery failure rates of your machine can be minimized.
