3. After turn on the switch, there will be a 10 seconds for warm-up, then it gets into detection status. During detection If red LED flashes along with the buzzer sound discontinuously, shows the gas leakage being over the low alarming level; If the red LED keep lighting along with the buzzer sound continuously, shows gas leakage being over the high alarming level. Please take effective action to get rid of the danger.
4. When the black fault LED turns on, shows its gas sensor with fault itself. Faults and settlement

Notification
1. It’s possible that detector gave alarming if there is plenty smoke, alcohol or perfume etc. volatile matters in the room.
2. Don’t calibrate the detector with unknown concentration gas.
3. Don’t use or store the products on place with causticity gas, such as chlorine.
4. Please take the battery out if not use for a long time.
5. Please contact your local distributor for calibrating the detectors once a year. Fault Reason Settlement

Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed

to reduce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Do not use machines or power tools in damp or

wet locations. Don’t expose to rain. Keep work area well lighted. Do not use

electrically powered tools in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not

let them handle machines, tools, or extension cords.

4. Store idle equipment. When not in use, tools must be stored in a dry location

to inhibit rust. Always lock up tools and keep out of reach of children.

5. Use the right tool for the job. There are certain applications for which this tool

was designed. It will do the job better and more safely at the rate for which it was

Gas Detector Safety Precautions

1. Never ignore a high alarm condition. This gas detector is designed to detect

hazardous atmospheric conditions. An indication of life threatening hazards should

be taken seriously.

2. Turn on, and allow the unit to warm up, before entering the area when gases are

to be detected.

3. High or off-scale readings may indicate a flammable gas concentration.

4. Before entering an area for testing, make a test of the unit in a safe area with a

small amount of known gas from a container. Then test again with clean air. The

reading should return to zeros.

5. Where a high or alarm condition is detected, evacuate the affected area and

contact the local fire department, gas company, or other proper authorities from

outside the affected area. Without switching on any electrical devices, properly

ventilate the area before reentering and retest.

6. Do not store or use this device in or around corrosive gases.

7. Do not drop this device. Damage will occur to the internal components.

8. Charge batteries and switch unit on or off only in a nonhazardous atmospheric

location.

9. Some vapor compounds may affect the operation of the sensor. Always use

your sense of smell to supplement the readings of the detector. If your sense

of smell detects gas that the meter does not, get the detector calibrated imintended.

Do not modify this tool and do not use this tool for a purpose for which

it was not intended.

6. Check for damaged parts. Before using any tool, any part that appears damaged

should be carefully checked to determine that it will operate properly and perform

its intended function. Any part that is damaged should be properly repaired or

replaced by a qualified technician. Do not use the tool if any switch does not turn

On and Off properly.

7. Replacement parts and accessories. When servicing, use only identical

replacement parts. Use of any other parts will void the warranty. Only use

accessories intended for use with this tool. Approved accessories are available

from us.

8. Do not operate tool if under the influence of alcohol or drugs. Read warning

labels if taking prescription medicine to determine if your judgment or reflexes

are impaired while taking drugs. If there is any doubt, do not operate the tool.

9. Maintenance. For your safety, service and maintenance should be performed

regularly by a qualified technician.

IMPORTANT: Performance of this tool may vary depending on variations in battery

power or other circumstances. we cannot be held responsible for any damage, injury, fire, or death caused by an inaccurate reading or a failure to detect on the part of this device.

Operation

1.      Open the back cover and cased the 1.5VAA batteries according to their polarity.

2.      Turn switch to the top, the power LED will be on, green LED shows the normal voltage and the orange LED show the low voltage. The power LED will be always on during this detection.

3.      After turn on the switch, there will be a 10 seconds for warm-up, then it gets into detection status. During detection If red LED flashes along with the buzzer sound discontinuously, shows the gas leakage being over

the low alarming level; If the red LED keep lighting along with the buzzer sound continuously, shows gas leakage being over the high alarming level.

Please take effective action to get rid of the danger.

4.     When the yellow fault LED turns on, shows its gas sensor with fault itself.

Calibration of the gas detector may be necessary by a qualified technician. If the sensor fails calibration, have the sensor replaced by a qualified technician. Never use any source of ignition to test the accuracy of this device.

Warning: The warnings, cautions, and instructions discussed in this instruction

manual cannot cover all possible conditions and situations that may occur. It

must be understood by the operator that common sense and caution are factors

which cannot be built into this product, but must be supplied by the operator.

Note: Gases that are heavier than air, such as propane, can be detected nearer the

floor.

Warning: When the WARNING HIGH alarm is sounding, leave the room immediately.

Properly ventilate the area before reentering.

Only after leaving the test area, press the On/Off Switch to the Off position.

Unpacking

When unpacking, check to make sure the tool is intact and undamaged. If any parts

are missing or broken, please call us at the number on the cover of this manual.

Maintenance

1. It’s possible that detector gave alarming if there is plenty smoke, alcohol or perfume etc. volatile matters in the room.

2.. Please take the battery out if not use for a long time.

3. When the unit is not detecting properly, have a qualified technician calibrate

the unit or replace the sensor.

4. Do not store or use the Gas Detector in an area when corrosive gases are

present.

5. Do not expose the unit to high concentrations of gas for long periods. This will

shorten the life of the sensor.

6. If the unit is not functioning, repeat the start-up procedures
