IMPORTANT SAFETY INSTRUCTIONS

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 these instructions - This operator’s manual contains important safety and operating instructions for the MILWAUKEE M12 Sub-Scanner™ Detection Tool. Before using the Sub- Scanner, read this operator’s manual, your battery pack and charger operator’s manual, and all labels on the battery pack, charger and Sub-Scanner.

METAL Mode

In metal mode, the Sub-Scanner will detect both ferrous (>14 mm Ø) and non-ferrous (>16 mm Ø) metals in concrete up to a depth of 6". The Sub- Scanner can not reliably detect metal behind mate- rial of varying densities. Materials such as carpet, wire metal mesh backing, damp walls, and stucco may affect readings. Alternating surfaces, such as thick grout lines or extremely heavy plaster on drywall, may be detected or show as metal or studs.

WORK AREA SAFETY

•Avoid dangerous environments. Do not use in rain, snow, damp or wet locations. Do not use in the presence of explosive atmospheres (gaseous fumes, dust or flammable materials) because sparks may be generated when inserting or remov- ing battery pack, possibly causing fire.

PERSONAL SAFETY

•Stay alert, watch what you are doing and use common sense when operating the Sub-Scan- ner. Do not use while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention may result in serious personal injury.

•Do not overreach. Keep proper footing and balance at all times. This enables better control in unexpected situations.

BATTERY USE AND CARE

•Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

•Use power tools only with specifically desig- nated battery packs. Use of any other battery packs may create a risk of injury and fire.

•When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery termi- nals together may cause burns or a fire.

•Under abusive conditions, liquid may be eject- ed from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

SERVICE

•Have your Sub-Scanner serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the tool is maintained.

•Do not disassemble. Incorrect reassembly may result in the risk of electric shock or fire. If it is dam- aged, take it to a MILWAUKEE service facility.

•Store in a cool, dry place. Do not store where temperatures may exceed 140°F (60°C) such as in direct sunlight, a vehicle or metal building during the summer.

•Do not remove or deface labels. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.

ASSEMBLY

WARNING Recharge only with the charger specified for the battery.

For specific charging instructions, read the operator’s manual supplied with your charger and battery.

Inserting/Removing the Battery

To remove the battery, push in the release buttons and pull the battery pack away from the tool.

To insert the battery, slide the pack into the body of the tool. Make sure it latches securely into place.

OPERATION

WARNING Always remove battery pack before changing or removing accessories. Only use accessories specifi- cally recommended for this tool. Others may

be hazardous.

On/Off

Press the button to turn the tool on and off.

Sleep Mode

The Sub-Scanner is automatically powered off in about 20 minutes after the last operation. To reset, press any button. If the display is blank when the Sub-Scanner is turned ON, charge the battery ac- cording to the battery/charger manual.

The Sub-Scanner does use battery power in sleep mode. Be sure to turn OFF the tool to conserve battery power.

Set-up

1.Turn on the Sub-Scanner (defaults to Metal mode without sound).

2.Press the MENU button.

3.Use the up and down buttons to scroll through the menu items (UNITS, SOUND). Use the Calibrate button to select.

UNITS - Select either English or Metric units. SOUND - Turn sound On or Off

4.Press the MENU button again to exit.

Selecting Mode

1.Turn on the Sub-Scanner.

2.Metal mode is the default scan setting.

3.To change between Metal and Stud, select the METAL and STUD buttons.

1.Turn on the Sub-Scanner. 2.Select Metal mode (default). 3.Standard depth of

scan (up to 4" deep scan) is defaulted. Press the Metal button to switch to Deep depth of scan (up to 6" deep scan).

NOTE: Deep mode scans may display more "noise" due to the higher sensitivity of the scan.

4.Hold the Sub-Scanner against the surface and press the Calibrate button.

5.The Sub-Scanner must remain flat against and in con-

tact with surface during entire scan. If CALIBRATION ERROR is dis -

played, the tool was placed in an area

where metal is pres- ent. Move the Sub- Scanner to another position and restart calibration.

6.When SCANNING is displayed, move the Sub- Scanner across the surface. Keep your free hand and other objects at least 6” (152 mm) away to avoid false readings.

7.When metal is detected, the type (ferrous or non- ferrous) and depth

are displayed. Con- tinue to move the Sub-Scanner across the surface. As you approach metal, the distance will de- crease. As you move away from the met- al, the distance will increase. When the minimum distance and indicator arrow are displayed, the Sub-Scanner is di- rectly over the metal at that distance. The

minimum distance and indicator arrow may ap- pear for a short span; the precise center is the center of this span.

NOTE: There may be additional metal material deeper in the wall, but only the closest metal

3object’s depth is displayed.
