for the locations of the fuse and
circuit breaker. IMT recommends using a fuse
removal tool, though pliers will suffice, when remov-

6.4.16 REPLACING THE INTERCOOLER FINNED
TUBES
Refer to
Figure 6-19
. The intercooler tubes (left and
right, respectively) may need to be replaced if their
fins become damaged. Damaged fins may hinder the
intercooler tubes’ ability to cool the circulating oil.
When replacing an intercooler tube:
• Never apply pressure to the finned-portions of the
tubes, as they are fragile and subject to damage.
• If additional leverage is desired to loosen or
tighten an intercooler tube connection, use and
additional wrench [
D
], placed on the connecting
elbow, to stabilize the tube while loosening or
fastening the tube end.
• When fitting a new intercooler tube into place,
use minimal bending to alleviate stress on the
fins.
6.4.17 PRESSURE (SAFETY) RELIEF VALVES
Refer to
Figure 6-20
. Although the pressure (safety)
relief valves have a reset ring at the cap,
DO NOT
test the valves by pulling on their reset rings. The
pressure relief valves require no safety testing;
should one prove faulty per indications given in the
Troubleshooting Guide
(
Section 7.2
), replace the
valve.
6.5 LONG TERM STORAGE
Parts can wear out over time, regardless of the
degree of usage. If storing the CAS40P unit for long
DANGER
Fuses will need to be replaced if blown
when tripped. When changing a fuse, or
dealing directly with any function of the
electrical system maintenance, always
be aware of the safety warnings given in
Section 1, Safety
.
NOTE
If valves vent
excessively
more than
once, replace valve.
