PERIODIC MAINTENANCE CHART
PRE-RIDE / DAILY INSPECTION
Perform the following pre-ride inspection daily, and when servicing the vehicle at each scheduled maintenance.
• Tires - check condition and pressures
• Fuel and oil tanks - fill both tanks to their proper level; do not overfill oil tank
• Engine oil — check for proper level; do not overfill oil tank
• All brakes - check operation and adjustment (includes auxiliary brake)
• Throttle - check for free operation and closing
• Headlight/Taillight/Brakelight - check operation of all indicator lights and switches
• Ignition switch - check for proper function
• Wheels - check for tightness of wheel nuts and axle nuts; check to be sure axle nuts are secured by cotter pins
• Air cleaner element - check for dirt; clean or replace
• Steering - check for free operation noting any unusual looseness in any area
• Loose parts - visually inspect vehicle for any damaged or loose nuts, bolts or fasteners
• Engine coolant - check for proper level at the recovery bottle
• Check all rear suspension components for wear or damage
COLD WEATHER OPERATION
If the vehicle 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 crankcase. Water in the bottom of the crankcase can
lead to engine damage and must be drained. Water accumulation increases as outside temperature decreases.
