4.8.3 Using chains
Chains can be used on the front wheels only when they are also used on the rear
wheels.
IMPORTANT: Use chains only with tyres that are designed for chain usage.
Follow the chain manufacturer's installation and user instructions carefully.
IMPORTANT: With larger tyres and a suspended cab (extra equipment), the
space between the mudguard and the tyre may become too small (under 25
mm). If the space is not large enough when you need to use the chains, adjust
the mudguards.
• Make sure that the chains are correctly tightened to avoid damaging the
mudguards.
4.8.4 Using twin-mounted wheels
Twin-mounted wheels can be used for decreasing the surface pressure, but not
for obtaining better traction.
1. Maximum allowed loading of twin-mounted wheels is one tyre multiplied by
1.76.
IMPORTANT: Do not exceed the maximum permitted axle loading even if the
tyres allow a heavier load.
2. If dual/extension wheels are used, check that the tyre size does not exceed
the permissible tyre sizes.
3. Adjust the track width of the inner wheels to the minimum value.
4. Adjust the turning angle, if necessary.
