A tire can explode during inflation. Replace a tire if it has any defect(s). Replace a wheel rim that has
cracks, wear, or severe rust.
Failure to comply could result in death or serious injury.
USE, MAINTENANCE AND REPLACEMENT
• When changing tires, select suitable tires for the actual tractor use, taking account of the recommended combina-
tions.
• Do not exceed the permitted load indicated on the tires.
• Do not exceed the speeds shown on the tires, as this both overheats and causes premature tire wear.
• Do not fit used tires where their previous use is unknown.
• Ask the manufacturer or a tire specialist for advice.
• After fitting tires, check that the wheel nuts are tight after 3 hours in operation and then periodically.
• Following this, check the tightness on a regular basis.
• Do not stand tires on hydrocarbons (oil, diesel, grease, etc.).
• The tires fitted on the tractor must be checked periodically, with special care given to:
- tread, must have regular consumption;
- flanks, must not have any cracks, swellings or abrasions.
• Have the tires checked by a specialist if one or more of the problems mentioned above should occur.
• Consult an expert if a tire is subject to violent shocks, even if there are no visible signs of damage.
• Tires age, even if used infrequently or not at all.
• Cracks on the walls, sometimes accompanied by bulges, are a sign of ageing.
• Tires fitted on tractors which are not used for extended periods tend to age more rapidly than those used more
frequently. In this event, it is advisable to raise the tractor from the ground and protect the tires from direct sunlight.
