MAINTENANCE AND LUBRICATION
Engine Oil Level
If the ATV is used year-round, check the oil level frequently. A rising oil level could
indicate the accumulation of contaminates such as water or excess fuel in the bottom of the
oil tank. Water in the bottom of the tank can lead to engine damage and must be drained.
Water accumulation increases as outside temperature decreases.
