contact a qualified auto technician.

2.  Always wear safety goggles to protect your 

eyes from battery acid, fuel, dust and dirt flying 

off moving engine parts.

3.  Always wear protective gloves when working 

with engine components.

4.  Always ensure that hands, hair, clothing or  

cables are clear of any moving or hot parts.

5.  Always follow the vehicle manufacturer’s  

recommendation and procedures.

6.  Always turn off the ignition of the vehicle  

before connecting the clamps to the battery 

and disconnecting the timing light.

7.  Always ensure that the hand brake is on and 

the vehicle transmission is in Neutral (manual) 

or Park (automatic).

8.  Always keep children and unauthorized  

persons away from the working area.

9.  Always store the timing light in a safe, dry and 

child proof location when not in use.

10. Always run the engine in well ventilated areas.

11. Always remember that a flashing timing light 

“freezes” rotating components. Do not be 

tempted to touch an apparently stationary 

component which is, in fact, rotating.

12. Never use the timing light if it is damaged in 

any way.

13. Never smoke, create sparks or use a naked 

flame near batteries.

14. Never rest tools or metallic items on top of the 

battery.

15. Never touch any ignition components when the 

ignition is on as very high voltages are present.

16. Never pull the cables or clamps from the  

battery terminals.

17. Never operate in the vicinity of flammable  

liquids or gases.

18. Never place the timing light on the hot
