8.8 TYRES
1. Each week check the tyres for wear and damage.
2. Each week check the tyre pressures. Optimum tyre pressures are shown in Table 7.
This information is given as guidance. If in doubt please contact KEENAN service.
WARNING:
When retting and re-inating tyre/wheel assemblies,
a safety cage should be used to prevent possible
injury. Incorrectly tted tyres are dangerous. Please
make sure tyre repairs are carried out by experienced
