Visually inspect the exhaust pipes, muffler and hangers for cracks, deterioration
and damage. Start the engine and listen carefully for any exhaust gas leakage.
Tighten connections or replace parts as necessary.
Fuel Lines and Connections, Fuel Tank Band and
Fuel Tank Vapor Vent System Hoses
Visually inspect for corrosion, damage, cracks and loose or leaking connections.
Tighten connections or replace parts as necessary.
Fuel Tank Cap Gasket
Visually inspect for cracks, deterioration and damage and replace if necessary.
Nuts and Bolts on Chassis and Body
Re-tighten the seat-mounting bolts and front/rear suspension member retaining
bolts to specified torque.
Propeller Shaft
Lubricate the propeller shaft spiders and slide yokes with lithium-base chassis grease
and the double cardan joint with molybdenum-disulfide lithium-base chassis grease,
and re-torque the bolt. Only a qualified technician should re-torque the bolt.
Radiator Core and Condenser
Inspect for debris and signs of damage. Have any problem repaired immediately
by a qualified technician.
Spark Plugs
Replace at specified intervals. Install new plugs of the same type as originally
equipped. A qualified technician should perform this operation.
Steering Gear Box
