Safety Precautions
Precautions on Operation
z Do not collide when operation. z For screen, flicker occurs at just the
moment of the engine ignition.
z Be careful when connect the main cable
and the diagnostic socket. Tighten the screw and avoid disconnecting or destroying the interface.
z Handle with care. Avoid collision. Unplug
the power after operation.
z When it is necessary to remove the leather
cover, pull out the CF card first and push in the ejector button to avoid scratching the leather cover.
z Put the cables, connectors and other
accessories into box.
z Hold the connector when plug or unplug it.
Do not pull the cable for unplugging.
z The matched lithium battery is special for
X-431TOOL. Do not use other battery,
otherwise it may cause explosion.
Safety Precautions
z Automotive batteries contain sulfuric acid
which is harmful to skin. When operation, direct contact with the automotive batteries should be avoided. Pay attention not to splash the sulfuric acid into eyes. Keep ignition sources away from the battery at all times.
z Engines produce various poisonous
compound (hydrocarbon, carbon monoxide, azote oxid, etc,) which should be avoided.
z Avoid contacting high temperature assembly
such as water tank and vent-pipe as the temperature of the running engine is very high.
z Before starting engine, put the speed lever in
the neutral position or in the P position to avoid injury.
z Wear an ANSI approved eye shield when
testing or repairing vehicles.
z If you are using the battery as a power
source, connect the RED (+) battery clip to the positive vehicle battery terminal and the
BLACK (-) battery clip to the negative.
Precautions on Operating Vehicle ECU
z Do not disconnect the vehicle inner battery
when connect the ignition switch. When
disconnection, transient voltage is very high,
which causes the damage to the sensor
and ECU.
z Do not put the wireless reproducer near to
the computer.
z Do cut off the power supply of the ECU
system before jointing on the vehicle.
z Pay more attention to the ECU and sensor
when operation is next to the ECU and
sensor.
z Do not use the pointer ohm meter instead of
digital instrument for testing ECU and
sensor without special explanation.
z Do not test the electric device about the
ECU with the test lamp without instrument.
z People who get in and out the vehicle must
wear the earthing metal strip with one end
on the wrist and other on the vehicle body.
z Pay attention to connect the ECU terminal.
