Maintenance
The maintenance activities are carried out by the
carrier driver.

The hydraulic system is under high pressure. If
hydraulic connections come loose, hydraulic oil will
squirt out under high pressure. Hydraulic oil
squirting out can lead to serious injury.
►
Immediately switch off the hydraulic attachment
and the carrier if you detect any leaks in the
hydraulic circuits.
►
Depressurise the hydraulic system (see chapter
Depressurising the hydraulic system).
