IMPORTANT SAFETY INFORMATION
When an engine is operating, keep the service area well-ventilated
or attach a building exhaust removal system to the engine
exhaust system. Engines produce various poisonous compounds
(hydrocarbon, carbon monoxide, nitrogen oxides, etc.) that cause
slower reaction time and result in death or serious personal injury.
Read all safety warnings and instructions.
*Note: Failure to follow the warnings and instructions may result in
electric shock, fi re and/or serious injury.
1. Always perform automotive testing in a safe environment.
2. Do not connect or disconnect any test equipment while the ignition
is on or the engine is running.
3. DO NOT attempt to operate the tool while driving the vehicle.
Have second personal operate the tool. Any distraction may
cause an accident.
4. Before starting the engine, put the gear lever in the Neutral

transmission) position to avoid injury.
5. NEVER smoke or allow a spark or flame in vicinity of battery or
engine. Do not operate the tool in explosive atmospheres, such as
in the presence of fl ammable liquids, gases, or heavy dust.
6. Keep a fire extinguisher suitable for gasoline/chemical/electrical
fi res nearby.
7. Wear an ANSI-approved eye shield when testing or repairing
vehicles.
8. Put blocks in front of the drive wheels and never leave the vehicle
unattended while testing.
9. Use extreme caution when working around the ignition coil,
distributor cap, ignition wires and spark plugs. These components
create hazardous voltage when the engine is running.
10. To avoid damaging the tool or generating false data, please make
sure the vehicle battery is fully charged and the connection to the
vehicle DLC (Data Link Connector) is clear and secure.
