Skid Steer Loader about to get a pre-operation inspection

How To Do a Skid Steer Pre-Operation Inspection

A skid steer or compact track loader is a significant investment. One of the most important and also overlooked aspects of operating equipment is doing a good pre-op inspection. The main reason you should do this is because it's the only way to make sure that your machine is ready to go, and it will prevent unnecessary down time due to mechanical issues. You don't need to be a diesel mechanic, but you should know what some basic maintenance items look like so you can spot problems before starting work. For example, if there are any leaks in the hydraulic system (a common issue), then you might need to replace the fluid reservoir, check fittings, replace hoses, etc.

Whether you have a used skid steer or a new one, there are 3 main pieces to completing a pre-operation inspection:

  1. The 360 degree walk around visual inspection

  2. Opening up the engine compartment and looking at the components

  3. Going into the operator's seat and doing a system check

Walk Around

The first thing you'll want to do is complete a full 360 degree walk around visual inspection. Some things we recommend checking and looking at:

  • Is there any damage to the glass and windows?

  • Is there anything wrong with the rollover protection and the cage?

  • Are all cylinders in good condition? Are there any leaks coming from anywhere?

  • Are all hoses and lines clean and dry? Are all the connections secure?

  • Take a look at all the grease points. Is there anything that looks overly dry that you need to address? Check all the bolts and pins.

  • Does the drive system look good? If wheeled, check the tires for wear. If tracked, are the rollers clean? How is the wear on the sprocket teeth? Is there an appropriate amount of tension on the tracks? Are there any leaks from the drive motors?

  • Check the top of the cab. Is there any new damage there?

  • Is there any damage to the exhaust system or radiator fans?

  • Check the bucket (or other attachment) and note how worn the cutting edge is.

  • In general, is there any dirt, rocks, debris that needs to be removed prior to operating the equipment?



After completing your visual walk around inspection, you'll want to open up the hydraulic fluid and engine compartments. Some things we recommend looking at:

  • Check the hydraulic fluid tank. Is the fluid level at the fill line?

  • Take a look at the engine bay. Is there anything sticking out or looking strange (e.g., loose wires or any obvious damage)?

  • Check your coolant level. Is the tank filled to the fill line?

  • Check the air filter about once a week to clean out any debris.

  • Check the engine oil level and make sure that it is at the fill line.

  • Take a look at the air intake and see if there is any obvious damage.

  • Check the belts and see if there's any cracks or signs of wear.

  • Take a look at the radiator fins. Is there any damage to the coils?


Operator's Seat

Last but not least, it's time to crawl into the cab and perform some system checks from the operator's seat.

  • Depending on the manufacturer of the unit, turn the key one click and check for any indicator or warning lights. Is there anything that indicates that the engine should not be turned on? For example, do you see any error messages pop up on the console?

  • Next, fully turn on the machine. Do you see any warning lights, indicators or error messages? If so, immediately power down the machine.

  • While the engine is on, spend a few moments listening to the sound. Is there anything about the idling sound that seems off and requires further diagnosis?

  • Last but not least, check your gauges. Do you have enough fuel for your planned operating session?


Final Thoughts

Every operator is different, so it makes sense that every pre-operation inspection for a skid steer or compact track loader would be different as well. The most important thing however is to do the inspection in a consistent manner so that issues can be detected proactively and any downtime can be minimized. If you're the owner of a skid steer business, performing pre-op inspections is a vital element of being able to deliver work on time for your customers.
