Safety Guidelines
Your Digital Multitester is designed for both, home and automotive use. The following Safety Guidelines are provided when it is used onvehicle testing. To prevent accidents that could result in serious injury and/or damage to your vehicle or test equipment, carefully follow these safety rules and test procedures.

Safety Equipment

Fire Extinguisher
Never work on your car without having a suitable fire extinguisher handy. A 5-lb or larger CO2 or dry chemical unit specified for gasoline/chemical/electrical fires isrecommended.

Fireproof Container
Rags and flammable liquids should be stored only in fireproof, closed metal containers. A gasoline-soaked rag should be allowed to dry thoroughly outdoors before being discarded.

Safety Goggles
We recommend wearing safety goggles when working on your car, to protect your eyes from battery acid, gasoline, and dust and dirt flying off moving engine parts.

Note:Never look directly into the carburetor throat while the engine is cranking or running, as sudden backfire can cause burn.

Loose Clothing and Long Hair (Moving Parts)
Be very careful not to get your hands, hair or clothes near any moving parts such as fan blades, belts and pulleys or throttle and transmission linkages. Never wear neckties or loose clothing when working on your car.
JewelryNever wear wrist watches, rings or other jewelry when working on your car. You´ll avoid the possibility or catching on moving parts or causing an electrical short circuit which could shock or burn you.

The carbon monoxide in exhaust gas is highly toxic. To avoid asphyxiation, always operate vehicle in a well-ventilated area. If vehicle is in an enclosed area, exhaust should berouted directly to the outside via leak-proof exhaust hose.

Setting the Brake
Make sure that your car is in Park or Neutral, and that the parking brake is firmly set.
Note: Some vehicles have an automatic release on the parking brake engaged when in the DRIVE
position. Refer to your vehicle service manual for more information.

Hot Surfaces
Avoid contact with hot surfaces such as exhaustmanifolds and piped, mufflers (catalytic converters), radiator and hoses. Never remove the radiator cap while the engine is hot, as escaping coolant under pressure may seriously burn you.

Smoking and Open Flames
Never smoke while working on your car. Gasoline vapor is highly flammable, and the gas formed in a charging battery is explosive.

Do not lay tools or equipment on thebattery. Accidentally grounding the “HOT” battery terminals can shock or burn you and damages wiring, the battery or your tools and testers. Be careful of contacts with battery acid. It can burn holes in your clothing and burn your skin or eyes.
When operating any test instrument from an auxiliary battery, connect a jumper wire between the negative terminal of the auxiliary battery and ground onthe vehicle under test. When working in a garage or other enclosed area, auxiliary battery should be located at least 18 inches above the floor to minimize the possibility of igniting gasoline vapors.

High Voltage
High voltage-30.000 to 50.000 volts-is present in the ignition coil, distributor cap, ignition wires and spark plugs.When handling ignition wires while the engine is running, useinsulated pliers to avoid a shock. While not lethal, a shock may cause you to jerk involuntarily and hurt yourself.

The jack supplied with the vehicle should be used only for changing wheels. Never crawl under car or run engine while vehicle is on a jack.
