1 Safety notes

To avoid possible harm, read and follow these instructions.

DANGER: Risk of death, personal injury, or property damage
Attaching the device to an elevated position may be dangerous if the attachment fails. Notice that moisture, dirt, surface properties, ambient temperature or aging may reduce the reliability of the supplied adhesive putty or affect the amount of adhesive putty required to reliably attach the device to a surface. If possible, restrict access to the hazard zone under the device when the device is attached to an elevated position. Always secure the device with additional supports if the device is attached to an elevated position, and it is possible that persons or animals may enter the hazard zone under the device. When the device cannot be reliably secured and the hazard zone under the device cannot be completely restricted, it is required that anyone entering the hazard zone under the device wears adequate personal protection equipment. Always remove the device before drilling.

DANGER: Risk of electric shock, fire, or property damage
Drilling a structure may damage a dangerously live electric cable or a pressurised pipe. Before drilling a structure, make sure the structure doesn’t contain dangerously live cables or pressurised pipes. If their existence cannot be excluded, the whole installation containing the structure should be de-energized and de-pressurised before drilling begins. In some cases, a decrease in locating accuracy may move the intended drill point.

WARNING: Risk of electric shock, fire, or property damage
When scanning a structure for live cables with the device, notice that the effective range of the voltage detector is limited, and scanning should be done from both sides of the drilled structure before drilling begins. Certain materials or structures may block the electric field of a dangerously live cable and render the voltage detector ineffective. Only cables that are live at the time of scanning may be detected with the voltage detector.

ATTENTION: Risk of property damage
When scanning a structure for pipes with the device, notice that the effective range of the metal detector is limited, and scanning should be done from both sides of the drilled structure before drilling begins. Only metallic pipes may be detected with the metal detector.

ATTENTION: Risk of locating error due to electromagnetic conditions
Large metallic objects, radio transmitters or industrial equipment may degrade locating accuracy or may prevent locating completely. Before attempting to locate a drill hole, take care that there are no large metallic objects at or near the intended drill hole. Large metallic objects include radiators, sheet metal, foil, and wire mesh among other things. Shut down or move any radio transmitters that actively transmit on the same frequency at least 10 m away from the intended drill hole. This includes other drill point locators.

ATTENTION: Risk of locating error due to device misorientation
Locating drill points with misoriented devices may degrade locator performance. Instructions for properly orienting the devices are provided in section 4: Operating Transmitter PKT2.

4 Operating Transmitter PKT2

4.1 Inspecting the work site for hazards

Carefully examine the drilled structure and surroundings for hazards before drilling.

DANGER: Risk of electric shock, fire, or property damage
Drilling a structure may damage a dangerously live electric cable or a pressurised pipe. Before drilling a structure, make sure the structure doesn’t contain dangerously live cables or pressurised pipes. If their existence cannot be excluded, the whole installation containing the structure should be de-energized and de-pressurised before drilling begins. In some cases, a decrease in locating accuracy may move the intended drill point.

4.2 Locating hazards with Transmitter PKT2

Transmitter PKT2 includes both metal and voltage detectors. Place the transmitter against the surface of the structure and move it slowly around the intended drill spot. Do this on both sides of the structure. When the metal detector or voltage detector LEDs turn on, it may be an indication of metal or a dangerously live object nearby. The more LEDs are illuminated and the higher the pitch of the sound indication, the closer or larger the object is.

WARNING: Risk of electric shock, fire, or property damage
When scanning a structure for live cables with the device, notice that the effective range of the voltage detector is limited, and scanning should be done from both sides of the drilled structure before drilling begins. Certain materials or structures may block the electric field of a dangerously live cable and render the voltage detector ineffective. Only cables that are live at the time of scanning may be detected with the voltage detector.
It is recommended to test the voltage detector on a known cable before scanning structures to familiarize oneself to the response and performance of the voltage detector. Construction materials often reduce the effective range of the voltage detector compared to the range in air.

ATTENTION: Risk of property damage
When scanning a structure for pipes with the device, notice that the effective range of the metal detector is limited, and scanning should be done from both sides of the drilled structure before drilling begins. Only metallic pipes may be detected with the metal detector.
It is recommended to test the metal detector on a known, exposed structure before scanning hidden structures to familiarize oneself to the response and performance of the metal detector.

4.3 Objects that may decrease locating accuracy

ATTENTION: Risk of locating error due to electromagnetic conditions
Large metallic objects, radio transmitters or industrial equipment may degrade locating accuracy or may prevent locating completely. Before attempting to locate a drill hole, take care that there are no large metallic objects at or near the intended drill hole. Large metallic objects include radiators, sheet metal, foil, and wire mesh among other things. Shut down or move any radio transmitters that actively transmit on the same frequency at least 10 m away from the intended drill hole. This includes other drill point locators.
Locating accuracy will be degraded if there are large metallic objects closer to the units than the distance between the units is. Additionally, distance display may indicate longer distance than actual. To avoid locating errors when large metallic objects are present, consider another drilling location, perform offset measurement or multi-point measurement.

4.4 Locating accurately thru thick structures

ATTENTION: Risk of locating error due to device misorientation
Locating drill points with misoriented devices may degrade locator performance. Alignment errors are highlighted when locating drill points thru thick structures. When using Transmitter PKT2 with Receiver PKR2 for straight drilling, the device bottoms should face each other on parallel planes both sides of the structure. When wedge pieces are used for angled drilling, the angle of both transmitter and receiver should be the same and they should be at the same angle to the horizontal. If necessary, use a spirit level to align the wedges.

4.5 Attaching Transmitter PKT2 to structures

DANGER: Risk of death, personal injury, or property damage
Attaching the device to an elevated position may be dangerous if the attachment fails. Notice that moisture, dirt, surface properties, ambient temperature or aging may reduce the reliability of the supplied adhesive putty or affect the amount of adhesive putty required to reliably attach the device to a surface. If possible, restrict access to the hazard zone under the device when the device is attached to an elevated position. Always secure the device with additional supports if the device is attached to an elevated position, and it is possible that persons or animals may enter the hazard zone under the device. When the device cannot be reliably secured and the hazard zone under the device cannot be completely restricted, it is required that anyone entering the hazard zone under the device wears adequate personal protection equipment. Always remove the device before drilling.
The supplied adhesive putty may be used to attach the Transmitter PKT2 to a dry, clean and solid surface. The putty has working temperature range of +15…+30 °C Use other attachment methods outside this temperature range or when the surface is wet or dirty.
When using other attaching methods, do not hang Transmitter PKT2 directly from a nail or a screw. Metal objects inside on near the centre hole degrade locating accuracy. Instead, attach Transmitter PKT2 to a piece of string and hang the string from a nail or a screw.
Place the device against the structure with the user interface towards the user. Place the centre hole of the transmitter on the reference point to be transferred.
Do not leave the transmitter attached for extended times because the attachment may fail. Before drilling, remove the transmitter from the structure to avoid damage or falling.
