I. Introduction for all Parts of the Timing Light
1.
Xenon lamp (light the timing mark during checking the timing)
2.
Flash frequency light switch (press this switch, the flash frequency light begins to flash, when
loosen, the flash stops)
3.
Inductive signal pickup device (connect high voltage wire of cylinder 1)
4.
Red battery jar clip (connect the battery anode + )
5.
Black battery jar clip (connect the battery cathode - )
II. Preparation before the use of the timing light
2.1. Before any test, check carefully and eliminate all mechanical trouble. Loose connection or
damage of the pipe, wire, and connector will result in abnormal operation of the engine.
2.2. Follow the repair manual, check whether the vacuum pipeline, wire, and wire bunch connector
are correctly connected, then check the following parts: all liquid level, spark plug and high
voltage wire of the spark plug, air filter, vacuum pipeline, belt, circuit, circuit connector
2.3.
Check the preparation of the ignition timing engine:
2.3.1 Before checking the ignition timing, make preparations of the engine, check the discharge
control plate of this vehicle or the test procedure and technical requirement for the ignition
timing in the repair manual. The discharge control plate of the vehicle is inside the engine
chamber, the usual position is: the back of the engine hood, the engine bulkhead, the top of
the valve chamber cover or near the engine hood lock.
2.3.2 Make the following preparations at least: Find the timing scale and the position of the indicator.
The timing scale and the indicator are usually at the crank pulley, crankshaft vibration damper
(at the front of the engine) or the flywheel (between the engine and the transmission), etc. (see
Fig. 2)
Three of many marking types

The timing scale and the indicator should be clean and clear. Apply chalk dust on them if necessary.
All the spark plugs work normally, the gap between the electrodes is correct. Start the engine, run to
the normal working temperature. Shut down the engine before connecting the timing light.
