OPERATION
1.
Y-8 Model Only: Charge battery before use.
2.
Connect yoke to power supply / battery pack.
3.
Select AC or DC operating mode using switch on back of yoke.
WARNING: Do not operate selector switch while yoke is energized.
4.
Position yoke legs at right angles to the direction of suspected discontinuities. Adjust legs
as needed for best contact with surface.
5.
Depress trigger to energize yoke. Apply magnetic particles to area between legs.
a.
If using dry powder, blow off excess while yoke is energized to reveal indications.
b.
If using fluorescent particles, view surface with UV-A in darkened environment to
reveal indications.
6.
Evaluate indications for size, shape, and relevant location.
7.
Reposition yoke legs at 90-degrees to previous position and repeat steps 4-5 to reveal
indications in all directions.
8.
Y-6 and Y-7 Models Only: Demagnetize by energizing yoke then slowly withdrawing it from
the surface, up to 18 in / 45 cm distance. NOTE: Use AC mode for demagnetization.

MAINTENANCE
•
Use mild soap and a damp cloth to clean the yoke housing.
•
Do not spray yoke housing or immerse any part of yoke in liquid.
•
Legs may be detached at the joints for cleaning.
•
Use a rust-preventative spray (LPS-2 or equivalent) on legs for lubrication.
Battery Charging
•
Recharge battery after every 8-10 hours of use or if stored for extended time.
•
Extreme discharge of battery will reduce battery life.
•
Connect battery to charger before plugging charger into line power.
•
Typical charging time is approximately 1.25 hours per 1 hour of use.
•
Typical use over 8-10 hour shift would require 10-12 hours to recharge.
SERVICE
WARNING
Disconnect coil from line power before any disassembly or service.
CAUTION
To assure product safety and reliability, repairs should be performed
by Magnaflux Authorized Service Center using original parts.
WARNING
If the AC/DC Conversion Assembly or the switch is replaced,
gasketing must be inspected for integrity and replaced as needed.
Failure to do so may allow liquid intrusion during use, which can result
in electrical shock hazard and permanent damage to the yoke.
