21.6.1 Checking and maintaining tyres
Risk of injury due to reduced driving stability!
If the pressure of the tyres on the machine is too low, people are at risk due to reduced driving
safety.
• Never operate the machine at the tyre pressure usual for transportation of the tyres.
• Keep the valve caps screwed on the valves to keep dirt out.
• Check the tyre pressure daily and correct if required.
Fig. 556
Every day check the tyres for damage and obviously low pressure, as the service life of the
tyres depends greatly on the air pressure.
• Immediately repair any cuts or breaks in the tyres or change the tyres.
• Do not expose tyres to oil, grease, fuel, or chemicals or leave them too long in the sunlight.
• Drive carefully; avoid driving over sharp stones or edges.
• Check the tyre pressure at least once a week using an accurate testing instrument and
correct the air pressure if required, see chapter Description of machine, "Technical data of
the machine".
