distribution parts are leaking. To avoid personal injuríes, always wear
protection gloves and protection goggles during works with the hydraulic
system.
Warning!
Before starting the motor, place the machine outdoors or install an extraction
device for the exhaust fumes. Otherwise the personel will be poisoned.
This section describes the trouble shooting procedures in absence of proper functions at
the hydraulic assisted steering and implement lifter. It also describes the correction
measures in each actual case. When following the trouble shooting table, it is provided that
the following states are fulfilled:
• Parking brake not activated.
• A new filter installed
• Motor is running in full speed.
• The oil reservoir level shall be adjusted.
• The machine is warmed up during at least 10 minutes to a oil temperature of at least
50°C.
The pressure (about 35 bar) in the external hydraulic is divided between the implement
lifter and the steering torque converter. If anyone of theese gets more pressure, the other
must gets less. See the diagram.
