DANGER
Too high a tyre pressure can cause the tyres to burst and too low
a tyre pressure can result in overloading of the tyres.
The tyre pressure shown below is permitted, depending on tyre size, tread and PR
number or load index. The PR number or load index and tread designation are
vulcanised into the tyres.

WARNING
Risk of accidents due to escaping hydraulic fluid
Hydraulic fluid which is ejected under high pressure (hydraulic oil)
can penetrate the skin and cause serious injuries. In the event of
injuries, consult a doctor immediately.
Due to the risk of injury, always use suitable tools when looking
for leaks.
Always wear appropriate protective clothing.
Carry out a visual inspection of the hydraulic couplings.
Look for leaking hydraulic oil at the hydraulic couplings.
Connect the hydraulic lines to the tractor.
Check that the hoses are leak-free when under pressure.
Faulty or leaking couplings must be repaired or replaced immediately by a special-
ist workshop.
