Yamaha YFM7FGX Grizzly 700 FI 2008 Owner's Manual

To change the oil, warm up the engine, place the ATV on a level surface, remove the skid plate, drain the oil by removing the drain plug, replace the oil filter, and refill with the recommended oil type and amount.
Yamaha recommends using a 10W-40 API SJ or higher, JASO MA standard motor oil for optimal performance and protection.
Check the battery charge, ensure the fuel is fresh, inspect the spark plug for wear or carbon buildup, and verify that the fuel pump is functioning properly.
Remove the air filter cover, take out the filter, wash it with a mild detergent and water, let it dry completely, apply a light coat of air filter oil, and reinstall it.
Regular maintenance should be performed every 6 months or 100 hours of operation, whichever comes first. This includes checking brakes, throttle, and fluid levels.
Stop the engine immediately, allow it to cool, check the coolant level, inspect for any leaks, and ensure the radiator fins are clean and unobstructed.
Locate the brake adjustment screws, turn them clockwise to tighten or counterclockwise to loosen, and test the brakes for proper response.
Common issues include blown fuses, corroded connectors, and a weak or dead battery. Regular inspection and cleaning of electrical components can prevent these issues.
Maintain proper tire pressure, clean the air filter regularly, ensure the spark plug is in good condition, and avoid aggressive riding.
Inspect the spark plug, check the fuel quality, ensure the air filter is clean, and examine the fuel injector for clogs or damage.
