Warning! Hydraulic oil under pressure can be very dangerous if hoses, lines
or other distribution parts are leaking. To avoid personal injuríes, always wear
protection gloves and protection goggles during works with the hydraulic sys-
tem.
Warning! Before starting the motor, place the machine outdoors or install an
extraction device for the exhaust fumes. Otherwise the personel will be poi-
soned.
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 followingthe 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 auxiliary hydraulic is divided between the implement lifter
and the steering torque valve. If anyone oftheese gets more pressure, the other must gets
less. See the diagram.
The adjustment screw in the figure below is accessible after that the instrument covers are
dismantled. See "Instrument covers" at page 10 in section "2 Chassis".
