Fuse Panel
The electrical systems in the PT
machines are equipped with
fuses that protect the electrical
components from damage. They
are located on the fuse panel
behind the access cover on the
lower right side of the cab interi-
or. (fig. 6)
In the event of an electrical mal-
function, the most logical place
to start is at the fuse panel.
Check the fuse related to the
problem you are having and
inspect it. If the fuse appears
black and burned, it needs to be
replaced. Replace fuses with
the correct amperage replace-
ment fuse only. Replacing a fuse
with one of a lower amperage
rating may lead to premature
fuse failure. Replacing a fuse
with one of a higher amperage
rating may burn out the electrical
component the fuse was meant
to protect. See the troubleshoot-
ing section in this manual for an
additional resource to aid in
tracking suspected electrical
problems.
Undercarriages
The undercarriage assemblies in
the PT machines typically oper-
ate in harsh working conditions.
They work in mud, gravel, debris
and various other abrasive
materials during operation. ASV
recommends a daily inspection
of the undercarriage assemblies
and cleaning if necessary.
Materials that are particularly
sticky or abrasive like clay, mud,
or gravel should be cleaned
from the undercarriages more
often to minimize component
wear. A pressure washer works
well for cleaning materials from
the undercarriages. At times
when a pressure washer is not
available, use a bar, shovel or
similar device to remove foreign
materials.
When cleaning, pay particular
attention to the drive tables,
sprockets, and the front and rear
wheels where debris is more
likely to accumulate. If working
in scrap or debris, inspect more
often and remove foreign objects
that may wrap around or lodge
themselves between compo-
nents causing premature wear
and damage.
Operating the PT in loamy sand
or on turf or other finished sur-
faces may require less frequent
cleaning, but daily inspection is
still advised.
