WARNING Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
Electrical safety a. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
b. Do not expose the tool to rain or wet conditions.
Water entering a tool will increase the risk of electric shock.
c. Do not abuse the cord. Never use the cord for carrying, pulling or disconnecting the tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
Personal safety a. Stay alert, watch what you are doing and use common sense when operating a tool. Do not use a tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating a tool may result in serious personal injury.
4. b. Use personal protective equipment.
Always wear eye protection.
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c. Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
d. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from electrical parts.
Loose clothes, jewelry or long hair can be caught in parts.
e. Only use safety equipment that has been approved by an appropriate standards agency.
Unapproved safety equipment may not provide adequate protection.
Eye protection must be ANSI-approved and breathing protection must be NIOSH-approved for the specific hazards in the work area.
Power tool use and care
Safety equipment a. Store idle tools out of the reach of children and do not allow persons unfamiliar with the tool or these instructions to operate the tool.
Tools are dangerous in the hands of untrained users.
b. Maintain tools. Check for misalignment or binding of parts, breakage of parts and any other condition that may affect the tool’s operation. If damaged, have the tool repaired before use.
Many accidents are caused by poorly maintained tools.

General Operating Instructions
1. Remove the protective tip from the Probe.
Be careful, the tip is sharp.
Note: Before each use, first test the Circuit
Tester on a known, working 6V or 12V source so you are sure it is in proper working order.
2. To test 6 volt or 12 volt fuses, wiring, or other
6V/12V circuitry, connect the Cord Clamp to one side/end of the fuse, wire, vehicle battery post, etc. (either positive or negative pole).
3. Gently touch and hold the tip of the Probe against the other side/end of the object being tested.
4. If the Bulb inside the Handle illuminates, this indicates there is electricity flowing through the circuit. No illumination of the Bulb indicates no electricity flowing through the circuit and that repair or replacement of the object being tested is needed.
5. When finished using the Circuit Tester, replace the protective tip and store the tool in a clean, dry, safe location out or reach of children.
