Safety Precautions
5568 1
Always observe safety precautions whenever working on a vehicle.
DO NOT wear loose clothing, watches, rings or other jewelry when working on a
vehicle.
Always wear safety eye protection.
Only work on a vehicle in a well-ventilated area.
Put transmission in “park” (for automatic) or “neutral” (for manual). Set parking
brake. Put blocks on drive wheels.
Avoid moving fan blades or any potentially moving parts. WHEN USING THE
TIMING LIGHT, THESE PARTS MAY APPEAR TO BE STOPPED OR
MOVING SLOWLY.
Avoid hot engine parts.
The vehicle battery produces explosive gases. DO NOT smoke or allow spark or flame
near the battery.
BE CAREFUL when working near high-voltage parts (spark plugs or coil terminals).
Turn off ignition before connecting (or disconnecting) any testing equipment.
ALWAYS READ THE VEHICLE'S SERVICE MANUAL BEFORE
PERFORMING ANY PROCEDURE. OBSERVE ALL SAFETY PRECAUTIONS.
NOTE
EMI/RFI problems with Digital Timing Lights:
■ If the Digital Timing Light readout becomes inoperative or locks up during
use, disconnect and reconnect the timing light's positive battery clip from
the battery to reset the unit.
■ Some aftermarket ignition systems and/or specialty spark plug wires (solid
core wires, racing wires, off-road wires) radiate above normal Electro-
Magnetic Interference (EMI) and Radio Frequency Interference (RFI) which
can cause improper operation of testing equipment. Please contact these
manufacturers for instructions on how to use an inductive pickup with their
systems.
■ It may be necessary to replace the No. 1 spark plug wire with an O. E.-style
plug wire during testing.
