BASIC PRECAUTIONS
q Never disassemble, repair, modify, or move the KOMTRAX Plus, communications terminal, antenna, or
cables. This may cause failure or fire on the KOMTRAX Plus communications terminal or the machine
itself. (Your Komatsu distributor will carry out removal and installation of the KOMTRAX Plus and
communications terminal.)
q Do not allow cables or cords to become caught; do not damage or pull cables or cords by force. Short
circuits or disconnected wires may cause failure or fire on the KOMTRAX Plus communications termi-
nal or the machine itself.
q For anyone wearing a pacemaker, make sure that the communications antenna is at least 22 cm (8.7
in) from the pacemaker. The radio waves may have an adverse effect on the operation of the pace-
maker.
q Near the blasting jobsite, there may be a danger of unexpected explosion due to use of interactive
wireless communication device of KOMTRAX Plus and resulting serious personal injury.Make sure to
operate the machine away from the blasting jobsite.If you have to operate the machine within 12 m (39
ft 4 in) from the blasting jobsite or the remote blasting device, ask your Komatsu distributor to discon-
nect power source cable of KOMTRAX Plus in advance.
If there are any restriction or law of the territory or country where the machine equipped with this
device is used, such restriction or law has a priority than this warning.
KOMTRAX Plus specifications are as follows.
Rated horsepower: 5 - 10 W
Operating frequency: 148 - 150 MHz
q Even when the key in the starting switch of the KOMTRAX Plus system equipped machine is at the
OFF position, the equipment is still consuming a small amount of electricity for the communication
function. When putting the machine into storage for one or more months, follow the instructions set
forth in “LONG TERM STORAGE (3-238)).”
When storing the machine for a long time, first turn the starting switch to the OFF position, wait over
three minutes, then switch off the battery isolator switch. By switching off the battery isolator switch,
battery drain can be reduced. Note however that it stops KOMTRAX Plus functioning at the same time.
q Please contact your Komatsu distributor before installing a top guard or other attachment that covers
the antenna.
q Be careful not to get water on the communications terminal or wiring.
The communications terminal uses wireless communications, so it cannot be used inside tunnels, underground,
inside buildings, or in mountain areas where radio waves cannot be received. Even when the machine is outside,
it cannot be used in areas where the radio signal is weak or in areas outside the wireless communication service
area.
There is absolutely no need to inspect or operate the KOMTRAX Plus or communications terminal, but if any
abnormality is found, please contact your Komatsu distributor.
