Troubleshooting
6.1
General information on troubleshooting
Many of the functions of the drill are controlled by a series of electrical, hydraulic and mechanical
components. A good way to exclude many of the sources of faults from the start is to first deter-
mine whether the fault is electrical. Because of this, first check whether the electric circuit is
closed to the last electric component in the chain.
Then continue troubleshooting by first performing easy inspections, in order to quickly exclude
other sources of faults.
Carefully read the attachments
”7.2 Hydraulic diagram” on page 124
, which can be useful during troubleshooting. Also study the descriptions under
.
6.1.1
Electric fault
General checks for electrical faults:
!
Is the Control Station properly connected to the tractor?
!
Is at least 12 V reaching the Control Station from the tractor?
!
Have the + (brown) and ground (blue) been connected properly?
!
Check whether the automatic fuse of the Control Station has tripped.
!
Check the settings on the Control Station
!
Check whether both connectors of the intermediate cable are correctly connected to the Control
Station and Workstation.
!
Check that the connectors and sleeves of all 4-pole switch connectors are clean, free from dam-
age and are not depressed. Spray the connectors with contact spray, type 5.56.
!
Check whether the intermediate cable is pinched or otherwise damaged.
6.1.2
Hydraulic fault
General checks for hydraulic faults:
!
Check that the hydraulic hoses have been connected to the correct hydraulic coupling on the
tractor. Hoses with the same colour coding constitute a pair.
!
Make sure the hydraulic hoses' quick couplings are dimensioned for and fit the couplings on
the tractor. A number of couplings are available in the market, however, although most are
standardized problems still exist. Problems that may appear could be that female and male cou-
plings operate as non-return valves, i.e. that the machine can be raised but not lowered or vice
versa. The problem may be aggravated by a high flow rate or worn couplings.
