SERVICE TOOLS
It is recommended that the following tools are used
when carrying out pressure or temperature checks
during maintenance procedures. These tools, along
with other general service tools, are available from
your dealer. Refer to Section 300-0070, SERVICE
TOOLS, for part numbers of these tools.
Multi-gauge
The multi-gauge is basically four pressure gauges in
one. Continuous system pressure readings are
indicated on one of three simultaneously reading
gauges through a pressure range of 762 mm (30 in) of
vacuum to 345 bar (5 000 lbf/in
2
).
Non-contact Infrared Thermometer
The infrared thermometer can be used to spot heat
problems early in electrical, mechanical and hydraulic
systems. Hand held and easy to use, you simply aim,
pull the trigger, and read the temperature. Since there
is no need to touch what you are measuring,
temperatures of hard-to-reach or moving components
can be taken without getting burned or shocked.
