Replace any deteriorated or damaged parts and, if necessary, repack the grease.
Selected models also require periodic inspection of the drive shaft bolt for proper
torque. A qualified technician should perform these operations.
Engine Air Filter
Replace at specified intervals. When performing inspections, check for damage,
excessive wear and oiliness, and replace if necessary.
Engine Coolant
Drain and flush the cooling system and refill with an ethylene-glycol type
coolant. Inspect the radiator and condenser for leaves, dirt and insects and clean
if necessary. A qualified technician should perform these operations.
Engine Oil and Oil Filter
Replace the oil filter and drain and refill the engine oil at specified intervals.
For recommended oil grade and viscosity, refer to the
Owner’s Manual.
Engine Valve Clearance
Inspect for excessive lifter noise and engine vibration and adjust if necessary.
Aqualified technician should perform this operation.
Exhaust Pipes and Mountings
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
