Equipment Maintenance Recommendations

Oil is the lifeblood of any internal combustion engine. We recommend using Chevron Delo 400 XSP SAE 15W-40, a heavy-duty engine oil chosen for its ability to perform under harsh conditions. For optimal performance, we suggest your initial engine oil change at 10 hours of use. Regardless of the brand you select, it’s crucial to use a 15W-40 full synthetic grade oil to protect your investment. Following a proper maintenance schedule, we recommend oil change intervals at least every 50 hours of operation, especially if your system is equipped with a new filter. Additionally, it is advisable that both engines and hydraulic systems reach their operating temperatures before use to ensure effective hydraulic oil replacement.

We recommend a readjustment of all bolts after five to 10 hours of use as part of your maintenance schedule. Machines should be regularly inspected for loose bolts, and special attention should be given to the swing motor bolts. Additionally, don't forget to schedule your engine oil change and hydraulic oil replacement during these inspections.

We recommend readjustment of the drive tracks after every five to 10 hours of use as part of your maintenance schedule. Ensure that the drive tracks have no more than one inch of deflection, which is crucial for optimal performance before an engine oil change or hydraulic oil replacement.

We recommend replacing all filters as needed or at least every 50 hours of operation as part of your maintenance schedule, along with regular engine oil changes and hydraulic oil replacements.

The grease fittings should be greased every five to 10 hours of operation as part of your maintenance schedule. Special attention should be paid to the slewing bearing, which needs to be greased liberally every 90 degrees of a complete rotation of the excavator body. The left grease fitting is designated for the slewing bearing, while the right is used for the slew motor. For optimal performance, we recommend the use of molybdenum grease due to its heavy-duty, high-pressure protection, complementing your engine oil change and hydraulic oil replacement practices.

Apply a thin grease coating to all hydraulic cylinders if your machine is parked in the elements for an extended period. Regular maintenance, including engine oil changes and hydraulic oil replacements, is crucial. Remember, rusted cylinders can quickly damage seals, leading to costly cylinder replacements.

We recommend that all electrical connections be coated with dielectric grease as needed to ensure reliable operation, especially as part of your maintenance schedule, which may include an engine oil change and hydraulic oil replacement.

We recommend a hydraulic oil replacement along with an engine oil change every 100 hours of operation as part of your maintenance schedule. It's essential to use a high-quality AW 46 hydraulic oil for optimal performance.

We recommend checking and adjusting the engine valve lash every 100 hours of operation for gas engines as part of your maintenance schedule. You can find Rato specifications on the product info page. For diesel engine valves, adjustments should be made if you notice loud tapping during startup, loss of power, or excessive exhaust smoke during operation. Additionally, remember to perform an engine oil change and hydraulic oil replacement as outlined in your maintenance schedule to ensure optimal performance.

We recommend that all coolant should be replaced every 5 years or 250 hours of operation as part of your maintenance schedule. Additionally, ensure you perform an engine oil change and a hydraulic oil replacement as needed. For optimal performance, use a quality coolant such as Peak or Prestone, and refer to the individual product manuals for any other recommendations.

We recommend shutting off the fuel supply valve during transport to prevent any fuel from entering the crankcase, which can be a concern between engine oil changes. Additionally, it is crucial to use appropriately sized tie downs strapped securely during transport. Adhering to this practice can also align with your maintenance schedule, ensuring both vehicle safety and efficiency. For tasks like hydraulic oil replacement, these precautions are equally important.

It will be difficult to restart if you allow diesel engines to run out of fuel. Once air fills the fuel rail, it becomes challenging to restart the engine. To avoid such issues, ensure your maintenance schedule includes regular checks, like an engine oil change and hydraulic oil replacement.
