—Read All Instructions Before Using The Analyzer—
Always wear eye protection when testing vehicles. Be extra careful
near batteries and moving parts. Do not lay tools on a battery.
Battery gas is highly explosive.
If a battery explodes flush the acid away from skin with generous
amounts of water. Follow up with a neutralizing solution of baking
soda and then more water.
Never use a wrench on the ungrounded battery terminal until
the grounded one has been disconnected. Contact between the
vehicle body metal and the hot terminal can cause sparks to ignite
gas or even weld tools into a battery short circuit.
Keep the space around a battery well ventilated.
Do not make sparks or allow flames near batteries.
Before working on a vehicle set the brakes and block the wheels.
Beware of automatic parking brake releases.
Keep your work area well ventilated and free of exhaust.
Avoid electrical shocks caused by getting close to live ignition wires
or touching the coil TACH terminal. A person's reaction near a
live engine can be more damaging than the shock.
Keep spark producing devices at least 0.5m (18") above the floor
to reduce the hazard of igniting gasoline vapor.
Do not let test leads wind up in a moving fan or pulley. Route
leads away.
Remove finger rings and metal wrist bands. They can short
terminals and become very hot from electric current.

Timing-Advance Test Procedure
This light measures advance by delaying the flash so that it appears to align the
crank shaft TDC mark to its pointer, and then displaying the degrees delayed.
Note that on engines with ignition contact points, dwell affects timing and must
be in calibration before timing is adjusted.
1. Connect the power leads: RED - positive, BLACK - negative. Hold the Mode
button for 2 seconds to select 2 or 4 stroke operation. Place the Inductive
Pickup around the #1 spark plug wire.
2. Prepare the engine for timing tests, such as: warming-up, disabling electric
and vacuum control lines, and cleaning the wheel timing marks. Then run
the engine. The light should begin flashing.
3. Press the Mode Button to toggle between RPM and Advance.
4. Point the light beam onto the degree marks at the engine damper wheel or
flywheel, and move the mark to the TDC position using the Timing Advance
Control Buttons, and read the timing advance on the display. NOTE: Align
your eye squarely with the timing marks when to avoid parallax error.
5. Compare the measurement with the specification. Adjustments are made
by turning the distributor slightly or by moving the ignition timing sensor.
6. Restore all engine parts to their normal arrangement.
Electrical Interference
In the event that the unit is subjected to extreme electromagnetic conditions
the display may appear to lock up. Simply disconnect the power lead and
reconnect to reset the unit.

Maintenance & Service
When cleaning the timing light, use a cloth dampened with waterless hand
cleaner. DO NOT use solvents such as acetone and benzene which can be
absorbed by and damage plastics. Promptly remove penetrating oils, gasoline,
and battery acid. The Inductive Spark Pickup is a plug-in replaceable lead. It
can be repaired or replaced if damaged.
Leave the Pickup latch Open when
not in use.
The magnetic cores are made of ferrite ceramic and, when kept
apart, they are less likely to break if the pickup is dropped.
