PRECAUTIONS
Inspect yoke before each use. If damage is present, see maintenance section for instructions.
WARNING
Yoke produces a strong magnetic field.
WARNING
Persons with pacemakers or medical implants must stay 1.5 ft / 0.5 m
away from yoke during operation.
WARNING
Immersing the yoke in liquid of any kind can result in electrical shock. Do
not use yoke in the rain.
CAUTION
GFCI / GFI / RCCB / ELCB protection is recommended to prevent
electrical shock.
CAUTION
Do not exceed the rated duty cycle. Continuous use of the yoke over
extended times will generate excessive heat and may permanently
damage the yoke.
CAUTION
Do not abuse cord. Never carry yoke by cord or yank to disconnect from
receptacle. Never retrieve yoke by pulling on cord. A suspension loop is
provided on the housing above the front coil to accommodate a belt clip
or hanger loop.
CAUTION
Only use outdoor rated extension cords

Y-2 Yoke Operating Manual
OPERATION
1. Attach power cord, making sure connection is secure. Connect the power supply to line power.
2. Position yoke legs at right angles to the direction of suspected discontinuities. Adjust legs
as needed for best contact with surface.
3. Depress trigger to energize yoke. Apply magnetic particles to area between legs. While
energized, blow o excess powder to reveal indications. To switch from UV mode to
visible light mode, press and hold the power button for 3 seconds.
4. Evaluate indications for size, shape, and relevant locations.
5. Reposition yoke legs at 90-degrees to previous position and repeat steps 2-3 to reveal
indications in all directions.
6. Demagnetize by slowly withdrawing yoke from surface, up to 18 in / 45 cm distance, while
yoke is energized.
7. OPTIONAL YOKE LIGHT: To install, slide over the rear leg with LEDs facing in. Push up
onto the housing until tabs are secured. Yoke light will automatically operate when yoke is
energized. To remove, pull sides out and down to disengage tabs, then slide o. No tools
are necessary for installation or removal.

Switch Replacement:
Use Y-2 Switch Replacement Kit p/n 629261. Refer to figure below.
1. Loosen TORX screw and remove the switch compartment cover.
2. Carefully unseat the switch and remove. NOTE: The torsion spring is under tension. Take
care not to lose the spring during disassembly of the switch compartment. If the spring
comes out, use the instructions below for reassembly of the trigger actuator.
3. Cut the wires to the old switch approximately halfway (1.5 in / 38 mm), leaving enough wire
for stripping and splicing. NOTE: Ensure that there is enough room to place the butt splice
underneath the switch.
4. Strip both ends of each wire (one from switch and other from yoke) and splice them
together, matching wire colors.
5. Fit the switch onto the alignment pins under the trigger actuator. Replace the switch
compartment cover and secure with the TORX screw until hand tight.
Trigger Actuator Assembly:
1. Place torsion spring into the housing with the straight leg in slot as shown in figure below.
2. Slide the pin through the two holes of the actuator.
3. To assemble actuator back into the housing, rotate bent spring leg to install angle and
place into the switch cavity area of the switch housing.
4. Place pin end into the boss hole and position the spring bent leg in the slot. Fit the actuator
into the switch compartment.

Foot Sections of legs worn or rounded File or grind feet back to original flat
condition or replace
Foot Sections turned and not making
full contact Adjust feet to make flat full contact with weight
Extension Cord too light to supply
adequate current See table in precautions for proper size
Improper test weight Part No. 624115 Test weight should be used
Leg bolts too tight Loosen slightly with properly sized wrench
Legs still or
not moving Legs rusted at joints
Remove bolts and legs. Clean with a wire
brush to remove rust buildup. Re-assemble
using a rust remover/preventer such as LPS-
2. Re-tighten bolts until legs are tight but still

Yugo Y-2 Manual de instrucciones
PRECAUCIONES
Revise el yugo antes de cada uso. Si hay daños, consulte la sección de mantenimiento para
obtener instrucciones.
ADVERTENCIA
El yugo produce un campo magnético intenso.
ADVERTENCIA
Las personas con marcapasos o implantes médicos deben
permanecer alejados a una distancia de 1,5 pies/ 0,5 m del yugo
durante el funcionamiento.
ADVERTENCIA
Si se sumerge el yugo en un líquido de cualquier tipo, pueden producirse
descargas eléctricas. No use el yugo bajo la lluvia.
PRECAUCIÓN
Se recomienda protección GFCI/GFI/RCCB/ELCB para prevenir las
descargas eléctricas.
PRECAUCIÓN
No supere el ciclo de trabajo nominal. El uso continuo del yugo durante
un tiempo prolongado genera un calor excesivo y puede dañar el yugo de
manera definitiva.
PRECAUCIÓN
No maltrate el cordón. Nunca levante el yugo por el cordón ni jale el cordón
para desconectarlo del tomacorriente. Se proporciona un arillo, delante de la
bobina, para colgarlo de un cinturón o colgarlo de un soporte.
PRECAUCIÓN
Solo use extensiones con calificación nominal para exteriores

OPERACIÓN
1. Conecte el cable de alimentación y asegúrese de que la conexión quede segura.
2. Posicione las patas del yugo en ángulos rectos en la dirección de las discontinuidades
sospechadas. Ajuste las patas para mejor contacto con la superficie.
3. Presione el gatillo para energizar el yugo. Aplique las partículas magnéticas entre las
patas del yugo. Durante la aplicación de energía, sople el exceso de polvo para revelar
las discontinuidades.
4. Evalúe el tamaño, forma y ubicación relevante de las discontinuidades.
5. Vuelva a posicionar las patas del yugo a 90 grados de la posición anterior y repita los
pasos 2 y 3 para revelar las discontinuidades en todas las direcciones posibles.
6. Retire lentamente el yugo de la superficie para desmagnetizar, a una distancia de 18 pulg. /
45 cm, con el yugo energizado.
7. LUZ OPCIONAL PARA YUGO: Para instalarla, coloque sobre la pata posterior con la cara
del LED hacia adentro. Empuje en el inserto hasta que las lengüetas queden fijas. La luz del
yugo funcionará automáticamente cuando el yugo esté energizado. Para retirarla, tire de
los extremos hacia afuera y hacia abajo para desenganchar las lengüetas y, a continuación,
deslice para extraerla. No se requieren herramientas para desinstalarla o extraerla.
