EQUIPMENT MANAGEMENT 17 AGGREGATES MANAGER March 2014 Dozer health checklist As it relates to the rest of a dozer's operating systems, remain- ing consistent and adhering to recommended service schedules is important. One of the most important activities that a dozer operator can engage in on a daily basis is the "pre-flight check." Before starting the machine, the operator should look for the following: • Check all lines and components for water or oil leaks. • Check that all visible nuts and screws are tightened. • Check for structural damage that may have happened overnight or since the last operation. • Check the oil level, as well as the coolant level at the overflow tank. • Check for clogging or damage to the radiator. • Check the engine accessory drive belt condition. • Check that the air filter restriction warning light is not illumi- nated. • Check the fuel tank, DEF tank (on dozers with selective catalytic reduction technology), and hydraulic reservoir levels. • Check that the hydraulic oil is clean. • Check that all baery connections are properly tightened. • Check the condition of the blades, cuing edges, and the ripper points. • Lubricate all grease points. Severe conditions, such as water im- mersion, may require more frequent greasing. Once you start the engine, it is also important to observe how the machine is running before beginning full operation. Factors to monitor include: • Did the engine start correctly? Are the exhaust fumes normal? Are there any unusual sounds? • Check for abnormal noise on the hydraulic components. • Check for water, fuel, or oil leaks. • Check that the audible alarm devices, working lights, and wipers are in working order. • Check that all hydraulic circuits are functioning correctly. It may seem like a lot of work, but these checks take a relatively short amount of time and may help prevent a more significant problem that causes downtime. Other important intervals to moni- tor include the following (be sure to check your original equipment manufacturer manual for machine-specific recommendations): 50 Hours: Drain water and sediment from the fuel filter every 50 hours; more oen if conditions require or if fuel quality is poor. First 100 Hours: (Note: these are specific to the first 100 hours of operation and are not regularly scheduled intervals). • Change the engine oil and filter. • Change the hydraulic oil filters, • Change the fuel filter. • Clean in-line DEF supply filter. 500 Hours: • Engine oil and filter replacement. • Fuel filter replacement. • Check baery fluid level. 1,000 Hours: • Change the oil in the final drive and the planetary drive. • Drain condensation from the fuel tank. • Clean the fuel tank cap. • Replace the hydraulic reservoir breather. 1,500 Hours: • Clean in-line DEF supply filter. • Replace the drive belt. 2,000 Hours: • Replace hydraulic oil filter. • Drain, flush, and replace engine coolant. • Change the hydraulic/hydrostatic drive system oil and filters. • Clean the reservoir suction screen. • Replace the engine primary and secondary air filter. In many cases, your dealer may assist you with this work through a planned maintenance contract or other agreement, but keeping track of these items is critical. A telematics system — common now to many manufacturers — automatically keeps track of these intervals and can alert the owner to impending service needs. Deal- er service departments can also be granted access to the telematics system to help monitor and plan for maintenance. Boom line: the bookkeeping on maintenance intervals has got- ten much easier with the advent of these technologies and empow- ers the equipment managers to be proactive in ensuring optimal uptime and the profitability of your dozer, ultimately driving down your owning and operating costs.
