Safety Warnings and Precautions

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

lowed 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 atmo-

spheric location.

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

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

of smell detects gas that the meter does not, get the meter calibrated im-

intended. 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 Harbor Freight Tools.

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. Harbor Freight Tools 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.

mediately. Calibration of the gas detector may be necessary by a qualified

technician. If the sensor fails calibration, have the sensor replaced by a quali-

fied 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 fac-

tors which cannot be built into this product, but must be supplied by the opera-

tor.

Gas Detection

1. Charge batteries. Plug the Power Adapter cord plug into the Charger Adapter

Connector on the side of the unit. Then, plug the Power Adapter into a 110 VAC

electrical outlet. Allow batteries to charge for 8 hours before using the Gas

Detector.

2. Warm-up Gas Detector. Slide the On/Off Switch to the On position and wait for

at least 10 seconds.

During this time, All Detection LEDs will first light green, then yellow, and finally

red.

3. In an area with clean air, slowly adjust the Sensitivity Adjust Knob so as to light

the lower LED only.

4. Perform a sample test. In a safe area, place the unit no closer than four inches

from a known combustible gas (i.e., cigarette lighter gas) and check the display

for a high reading. Then move the unit where the air is clear. The reading should

go to low again.

5. Adjust direction and place the Gooseneck Gas Sensor in the room where the

atmosphere is to be tested.

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

floor.

The bar graph readout will show the gas concentration present in % of LEL

(lower explosive levels) and PPM (parts per million), as shown above.

If the gas concentration reaches or exceeds the preset Low Limit Warning point

(500 PPM), the sound alarm will emit a tone, and the green LED will turn on.

If the gas concentration reaches or exceeds the preset Medium Limit Warning

point (10% LEL), the sound alarm will emit a higher tone, and the yellow LEDs

will turn on.

If the gas concentration reaches or exceeds the preset High Limit Warning, the

sound alarm will emit an emergency tone, and the red LEDs will turn on.

Warning: When the High Limit Warning alarm is displayed (all red LEDs), leave

the room immediately. Properly ventilate the area before reentering.

6. After leaving the test area, slide the On/Off Switch to the Off position.

Maintenance

1. Recharge batteries when the LOW BAT LED lights. Charge monthly, whether

the unit is used or not. If after recharging the batteries, the LOW BAT LED is

still displayed, replace the batteries with new ones of the same type. Refer to

the Specifications.

2. If the unit is not functioning, repeat the Gas Detection procedures as

described on page 5.

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

the unit, or have the technician replace the sensor with the extra supplied

sensor.

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

shorten the life of the sensor.

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

present.
