Scheduled Maintenance - Minelab F3 Service Manual

5.4

Scheduled Maintenance.

a. Scheduled Maintenance must be conducted at least once every six months.
This will normally be planned to coincide with the demining teams leave or stand down.
If higher fault rates are experienced on the detectors scheduled maintenance should
be conducted more often, as considered necessary.
b. Scheduled Maintenance is to be conducted by a trained technician with
appropriate spare parts and tools at hand. Scheduled Maintenance is a higher level of
maintenance than Daily Maintenance
detectors that have spent a long time in the field. Scheduled maintenance should be
conducted by a trained technician who has appropriate spare parts and tools at hand.
Scheduled Maintenance is best conducted during stand down of operators.
c. Scheduled Maintenance is very similar to the
more thorough and focuses on parts of the detector that may need attention after
prolonged use in the field. This Scheduled Maintenance should be used in conjunction
with the Service Manual.
d. First conduct the
to record or fix any fault discovered. Scheduled Maintenance is conducted as follows:
 Carefully inspect the skid plate for cracks, holes or damage and ensure it stays
in place and is not easily dislodged. Replace the skid plate if required. It is
normal that the skid plate will become worn and need replacing when used for
prolonged periods on hard rocky ground. It is not necessary to remove the skid
plate for cleaning.
 Inspect the coil for damage, if there are any holes or cracks in the coil that can
permit moisture or water inside the coil then it must be replaced.
 Tilt the coil forwards and backwards checking for firmness. If the coil tilt motion
is loose causing the coil to flop out of position during use of the detector the coil
friction blocks must be replaced.
 Open and close the lower camlock checking for firmness. Check that the coil
rotates through 270 degrees and that it doesn't rotate all the way around. Check
that when the camlock is closed the coil is held firmly. Ensure the coil is not
easily dislodged from the shaft of the detector. If there are problems push out
the camlock pins and remove the lower camlock body (and coil) from the shaft.
Inspect the lower shaft if it is cracked or damaged it must be replaced. Replace
the pressure block in the lower camlock. This part will wear out with normal use.
 Open and close the middle camlock checking for firmness. Check that when
opened the lower shaft can be extended and closed without obstruction and
when the camlock is closed the lower shaft is held firmly in place without
slipping. If there is a problem with the middle camlock replace the pressure
block in the middle camlock. This part will wear out with normal use.
 Open and close the upper camlock checking for firmness. Check that when
opened the shafts can be extended and closed without obstruction and when
the camlock is closed the middle shaft is held firmly in place without slipping. If
