Quality for Professionals
•
When driving on roads, which is only permitted with the grassland harrow lifted and
with folded side wings, the control block on the hydraulic cylinder prevents lowering
of the grassland harrow as well as of the folded up side wings (additionally secured
with a chain). This is also ensured in case of failure of the tractor hydraulic system.
19.4 Hydraulic system
•
The hydraulic system is under high pressure!
•
When connecting hydraulic cylinders and motors, the specified connection of the
hydraulic hoses must be observed!
•
When connecting the hydraulic hoses to the tractor hydraulic system, make sure
that the hydraulic system on the tractor and implement side is unpressurised!
•
For hydraulic function connections between the tractor and the implement, coupling
sleeves and connectors should be marked to rule out operating errors! If the
connections are interchanged, the function will be inverted
(e.g. lifting/lowering)! – Danger of accident!
•
Inspect the hydraulic hose lines at regular intervals and replace in case of damage
or wear! The replacement lines must comply with the technical requirements of the
implement manufacturer!
•
Due to the risk of injury, use suitable tools when searching for leaks!
•
Liquids escaping under high pressure (hydraulic oil) can penetrate skin and cause
serious injuries! Consult a doctor immediately in case of injury! (Risk of infection!)
•
Before working on the hydraulic system, park the implement, depressurize the
system and switch off the motor!
•
The safety chain should only be unhooked when it is relieved of tension! (cylinder
must be filled with oil)
19.5 Maintenance
•
Maintenance, repair, and cleaning work as well as the elimination of malfunctions
should always be performed when the drive is switched off and the motor is at a
standstill! – Remove the ignition key!
•
Check the nuts and bolts regularly for tight fit and retighten if necessary!
•
When performing maintenance on the lifted implement, always ensure safety
through suitable support elements!
•
When changing work tools with sharp edges, always use suitable tools and gloves!
•
Properly dispose of oils, grease and filters!
•
Always cut the power supply when working on the electrical system!
•
When performing electrical welding work on the tractor and mounted implement,
disconnect the cable on the generator and the battery!
•
Spare parts must at least comply with the technical requirements specified by the
implement manufacturer! This is ensured with original parts!
•
Cleaning must be performed with water or compressed air. Cleaning must be
carried with the implement lowered, shut down and secured to prevent it being
switched on again.
