Operating heavy machinery is very expensive. To not make repairs to this type of equipment due to poor policy maintenance is simply bad business. Sticking to a list of maintenance, you can take as little as 15 minutes a day to inspect and easily find a problem before lose working days due to repairs. Poor maintenance on heavy equipment can also endanger your employees.
Make a program to maintain equipment and stick to it. There are certain tasks to do daily, while other tasks need to be completed in a longer program. Once you decide something in a program, prepare a list of maintenance. Daily walk around each team in operation. While doing a visual inspection, check the use and signs of oil leakage or antifreeze. Make sure the tires are inflated to the proper pressure. Take time to remove debris from the machine. Palp bands and chains to make sure they are not too loose. Lubricate couplings that require daily greasing. Make sure emergency signals and safety equipment are in place. Check the fluid levels as oils, antifreeze and hydraulic. Fill them when necessary. Check the air filter and clean it if necessary.
When your machine has 500 operating hours, or about 3 months of service, you should perform a deeper maintenance. Change the engine oil, oil filters on both the engine and the hydraulic system. Replace diesel fuel filter also as part of the quarterly maintenance.
Maintenance at season finale
At the end of the season, or at least once a year change the transmission fluid and the hydraulic oil. Check the antifreeze in your radiator to make sure it is in good condition for the winter season. Check hoses and belts. Drain the fuel from the last season from the tank and fill with a mixture of fuels (can be biodiesel and diesel with ethanol) or “artic” type (a brand that prevents paraffin crystals to be deposited on the bottom) so that fuel line does not crystallize when you turn on in the cold weather. Thoroughly wash the vehicle. Pay special attention to cleaning the engine and chassis. Clean the cabin and air filters. Make sure the air conditioning unit is clean. Make sure all lights work and replace defective. Inspect the tires for signs of wear and tear. Replace worn tires during the off season to not lose valuable work time.
