1. Safety Precautions and Warnings
To prevent personal injury or damage to vehicles and/or the test tool,
read this instruction manual first and observe the following safety
precautions at a minimum whenever working on a vehicle:
Always perform automotive testing in a safe environment.

Wear safety eye protection that meets ANSI standards.
 Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot
engine parts.
Operate the vehicle in a well ventilated work area: Exhaust gases are poisonous.

Put blocks in front of the drive wheels and never leave the vehicle unattended while
running tests.
Use extreme caution when working around the ignition coil, distributor cap,
ignition wires and spark plugs. These components create hazardous voltage
s when the engine is running.

Put the transmission in PARK (for automatic transmission) or NEUTRAL
(for manual transmission) and make sure the parking brake is engaged.
Keep a fire extinguisher suitable for gasoline/chemical/ electrical fires nearby.

D on’ t connect or disconnect any test equipment while the ignition is on or
the engine is running.

Keep the tool dry, clean, free from oil/water or grease. Use a mild detergent
on a clean cloth to clean the outside of the test tool, when necessary.
When the power switch in the tool is depressed battery current/voltage is
conducted directly to the tip which may cause sparks when contacting gro
und or certain circuits. Therefore the tool should NOT be used around fla
mmables such as gasoline or its vapors. The spark of an energized tool
could ignite these vapors. Use the same caution as you would when
using an arc welder.
