information. If unreadable or missing, contact Harbor Freight Tools for a replacement. This enables better control of the power tool in unexpected situations. 3. Power tool use and care a. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. b. Remove the batteries from the power tool before making any adjustments, changing accessories, or storing power tools.
is any question about a condition being safe of unsafe, do not operate the Tool. 8. Keep the Metal Detector away from any lights, TVs, computers, and moble telephones. These can all cause electro-magnetic interference. 9. Only the Search Coil (23) and plastic section of the Lower Leg (18) are water proof. Do not immerse the unit any further into water beyond the plastic section of the Lower Leg. 10. Keep the Tool clean. Wipe the housing after each use.

Operating Instructions Read the entire Important Safety Information section at the beginning of this manual including all text under subheadings therein before set up or use of this product. Tool Set Up To prevent serious injury from accidental operation: Turn the Power Switch of the tool off and remove the batteries before adjusting tool or installing accessories. 2.
Dispose of spent batteries according to your local, state and federal regulations. Note: You can extend battery life by using earphones, which require less power than the built-in speaker. Note: Replace batteries when the LOW BATT light turns on in the View Meter (36). Headphones 1. Insert headphone (sold separately) jack into Earphone socket. 2.
Before Getting Started Figure 5 Before beginning an outside search, you must test the unit with samples of metal. Use the following: • an iron nail • a five-cent coin (nickel) • a one-cent penny (zinc coin, after 1982) • a 25-cent silver quarter. Place the Metal Detector on a wooden or plastic table with the Search Coil face up. Make sure the table is away from TVs, computers, or any device that can cause electromagnetic interference. See Figure 4.
1. To adjust the settings to PREVENT the unit from detecting iron metals, set the VOLUME and SENS dials at midpoint. 2. Then set MODE switch to DISC and the DISC/TONE dial to about “9 o’clock.” See Figure 7. Sweep the nickel in front of the Search Coil; the unit will not respond to the nickel or to the iron nail. But it will respond the other samples. 5. To prevent the zinc penny from being detected, set the DISC/TONE dial to about “1 o’clock” See Figure 9. Figure 9 Figure 7 3. 4.
the right. Sweeping any of the other samples will produce the “DI” sound. 8. Rotate the DISC/TONE dial to mark the other specific metals with the “KO” sound. To use the Metal Detector to “target’ specific metals, set the MODE switch to ALL METAL and the VOLUME and SENS dials to the middle. 9. use the TARGET button to determine the location of the metal. Press the red TARGET Button (6) on the panel. Set the silver quarter about five inches from the center of the Search Coil.
Tips for Searching in Different Environments There are many factors which influence the sensitivity and accuracy of detecting objects, including the angle, depth, size and oxidation of the target object. Various soil or seawater conditions, and also electromagnetic and electrical interference surrounding the target can also affect readings. Other metal detectors in the area will also cause interference, so when there is more than one unit in use, be sure they are at least 10 yards apart.
2. Handle the Metal Detector gently and carefully. Dropping it can damage circuit boards and the case, and can cause the Detector to malfunction. After Use, wipe external surfaces of the tool with a damp clean cloth, then dry. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the detector. 3.
