An easy way to remember the items to inspect is the phrase “START-GO.”

Steering and Drive System

  • Drive chain: Check your owner’s manual for proper adjustment. Inspect and lubricate the chain regularly.
  • Drive shaft: Check for leaks, and consult your manual for proper lubricant levels.
  • Handlebars (or steering wheel) and footrests: Shake to make sure they’re secure.

Throttle and Brakes

  • Throttle: Make sure it operates smoothly. On an ATV, the throttle should snap back to idle.
  • Ignition switch: Check for wear and proper operation.
  • Engine stop switch: Test operation.
  • Brakes: Test to make sure controls operate smoothly. Check and maintain fluid levels.
  • Foot shifter: Make sure it’s attached firmly and positioned for safe operation.

Activate Lights

  • Headlights and taillights: Turn them on.
  • Brake lights: Press the brake, and make sure the brake lights illuminate.


  • Confirm that your registration is current.
  • Make sure your Arizona OHV decal (or reciprocating state sticker) is attached.

Tires, Wheels, and Suspension

  • Tires:
    • Always use a low-pressure tire gauge to check tire pressure on ATVs and UTVs.
    • Make sure pressure is equal on all tires. Do not exceed design specifications.
    • Check for damage that could cause air leaks.
  • Axle nuts: Make sure they’re tight and secured by cotter pins.
  • Bearings: Try to rock the wheel on its axle to check for wear.
  • Spark arrestor/muffler: Make sure it’s attached firmly and working properly.
  • Major fasteners: Periodically tighten all major fasteners with hand tools.

Gasoline and Oil

  • Gasoline: Make sure the tank is full.
  • Oil: Check while the engine is off and the vehicle is on a level surface.
  • Leaks: Check for fuel or oil leaks.
  • Air filter: Make sure it’s clean, undamaged, and unblocked.
  • Spark plugs: Replace if necessary.

Operate Safely, Ethically, and Responsibly

Routine Maintenance
