CAUTIONS
Warning
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 compo-
nents create dangerously high voltages 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.
Don’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 ground or certain circuits.
Therefore the tool should NOT be used around flammables
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.
Before using the instrument, please read this manual
carefully for proper operation.
