Routine Maintenance is the Key to Longevity

Routine maintenance is vital for any equipment, from simple tools to large machinery like backhoes and bulldozers. Adhering to the manufacturer’s recommended maintenance schedule ensures your equipment lasts as long as needed. Preventative maintenance follows your equipment’s timeline, not your own.

Tailoring Maintenance to Usage

Maintenance isn’t a one-size-fits-all though. Needs vary by usage. Is your usage normal to heavy duty? Maintenance is less frequent. Is your usage severe duty? Then you need to take more time for truck service. The most frequent maintenance your truck will need is an oil change and a battery service. Regardless of usage, you should have your battery serviced every six months. Your battery takes a beating, and you don’t need it failing you when you stop for fuel.
