IMPORTANT INFORMATION
Scheduled Maintenance
NORMAL VEHICLE USE - The maintenance schedule in this section are based on the
assumption that your vehicle will be used as designed:
To carry passengers and cargo with the limitations indicated on the two vehicle
identification plates affixed to every vehicle. On reasonable road surfaces within legal
operating limits for at least several hours or kilometres and as a general rule, on a daily
basis.
SEVERE VEHICLE USE - Operating conditions, such as driving in dusty areas,
sweeper, agitator, agricultural, off-road vehicles, extended idling, refrigeration vehicles,
refuse vehicles, mining, logging, etc., or vehicles operated for frequent short trips, will
require more frequent vehicle maintenance in accordance with the severe operating
maintenance schedule in this section.
PREVENTATIVE MAINTENANCE - As with any mechanical device in operation, a
certain amount of wear occurs. The amount of wear depends on certain variables –
type and method of operation or application and the schedule of maintenance.
For example, if a vehicle is repeatedly overloaded, driven at excessive speed or
improperly shifted, no schedule of maintenance can prevent component failure. Also,
if preventive maintenance schedule is not followed, or is improperly carried out, no
amount of correct vehicle operation will prevent component failure.
NOTE
If vehicle application, operation and preventive maintenance schedules and procedures
are followed accordingly to IAL's recommendations, the life of the vehicle will be greatly
extended.
For example, regular attention to the engine oil is essential. The oil level must be
checked daily and oil added whenever needed. Also, the oil should be changed at the
intervals specified with the proper quality and viscosity of oil. If your engine should
run excessively low on oil or if the oil has lost its lubricating qualities because of old
age, serious engine damage could occur that is not be covered under the new vehicle
warranty.
