Unplanned maintenance is the kind of maintenance that is done abruptly because of a tool or equipment will be used. It often happens that the new equipment is used until it breaks without any treatment means, and then do repairs if you want to use. In the instrument maintenance management, the manner known to unplanned or emergency maintenance (emergency maintenance).
In general, the method used in the application of maintenance is a method of emergency and unplanned. Such methods allow equipment damage occurring or deliberately so as to re-use such equipment must be repaired or repairs. Unplanned maintenance will obviously interfere with the production process and usually costs incurred for repairs much more nstrument with regular maintenance.
From the description above can be concluded that the care system, there are two main activities related to maintenance actions, namely:
a. Preventive treatment
This treatment is intended to preserve the state of the equipment before the equipment becomes faulty. basically does is care taken to prevent kerusakankerusakan unexpected and determine the circumstances that can lead working facilities suffered damage when used in the work process.
Thus all the facilities work to get preventive care would be guaranteed the smooth working and always sought in a state that is ready for any work process at any time. This requires some planning and careful maintenance schedules and plans are more appropriate. Preventive care is very important because it uses a very effective job in facilities belonging to the “critical units” while the characteristics of the production facilities that are included in the unit are critical damage to facilities or equipment shall:
Endangering the health or safety of workers
Affect the quality of the resulting production
Causing congestion throughout the production process
price of the facility is quite large and expensive
In practice preventive care performed by a workshop or a company can be distinguished as follows:
Routine maintenance, ie maintenance activities and perawataan done regularly (every day). For example, cleaning equipment, lubrication oil, checking the contents of the fuel, cooling water and so forth.
periodic treatments, namely maintenance and care activities performed periodically or within a certain period, for example, every 100 hours of machine work, and then increased every 500 hours, and so on. For example dismantling the cylinder, valve adjustment – valves, intake and exhaust cylinder engine and so on.
Preventive treatment will be beneficial or not depends on:
Distribution of damage. In the scheduling and execution of preventive maintenance should show the kind of distribution of the damage, because by knowing the distribution type of damage can be prepared a plan of care that is truly appropriate to the background of the machine.
The relationship between treatment time prerventif against time to repair, should be held between the two this time and sought a balance can be achieved maximum points. if it turns out the amount of time for preventive maintenance for longer than the time finish sudden damage, then there is no real benefit to conduct preventive maintenance, better wait until the damage occurred.
require preventive maintenance as well as a list of routine work, include: equipment maintenance schedules, test result data, special equipment (if necessary), the charging information lubricants, maintenance guide, the level of knowledge workers on the job.
To provide information to the maintenance section, then each created on the maintenance schedule or form control card that can give information clearly. At each scheduled maintenance with tool written identification code number, name of the device, a replacement number, and date of the first installation and maintenance processing has been done.
b. Corrective repair
Repair is a maintenance tool, the goods / items broken system. Basically activities undertaken maintenance and upkeep is performed after the occurrence of a damage or abnormalities in the facilities or equipment. Improvement activities often referred to as repair activities.
Corrective maintenance can also be defined as an improvement that is done because of the damage that can occur due to execution of preventive maintenance and has performed preventive maintenance but to arrive at a certain time the facility and the equipment remains broken, so in this case the maintenance activities it is only waiting until the damage then repaired or corrected.
