Walk-Around Inspection

Walking up to your machine first thing is a great time to perform a walk-around inspection.

• Open the engine hood and covers to check for combustible materials around the engine and battery and liquid leakage around the engine and hydraulic devices
• Inspect the exterior of the machine for any damaged components. A few components to keep an eye out for are the lights, attachments, hoses, bucket, bucket teeth, hook, slip stopper, hook mount, handrail, crawler, shoe slide, track roller, idler, canopy, and cab.
• While sitting in the operator's seat, make sure to check the windshield, seat, seat belt, monitor, instruments and switches for damage and address any damaged, dirty or worn parts before operating the machine

Daily Inspection

Manufacturers recommend a 10 hour inspection to check your machine daily, and a great time to do so is first thing in the morning.

• Pull out the dipstick and check your oil levels as well, making sure to wipe down the dipstick with a clean rag before replacing it
• Check the dust indicator by making sure the red piston is not sticking out of the dust indicator

• Make sure to check if your fuel levels are low and add fuel to the fuel port while watching the sight gauge
