F. MAGNET NOT

will cause a reduction in holding power. This air gap can be caused by any non-magnetic separa-
�ion such as rust, paper, paint, dirt, scale, or burrs on either surface.
1) Check the amber indicator on the control panel and make sure it is flashing. If the indicator is
constant, release any residual tension on the lift bail until the indicator flashes.
NOTE:
If the lift bail

�he lift bail until the indicator flashes.
2) Check the LED on the remote to assure that it lights when the buttons are pressed. If this does
not occur, change the battery in the remote.
1) Check the battery terminals for a good clean contact. Clean if any corrosion is present. A battery
Will not charge properly if the terminals are with corroded.
2) Check for proper operation of battery charger. The power cord should be plugged in and the
magnet should be turned off. Check the fuse located in the cord receptacle. If the fuse is blown,
replace with 2 amp Slo Bio 5x20 mm type. Check the cables for any damage. When the charger is
initially plugged in, the battery indicator should light red. If not, see section (I) below.
3) As lead acid batteries age and/or become damaged internally, they do not retain their full charge
capacity. Indications of the battery conditions may be observed by the charger requiring longer
H. BATTERY NOT periods of time to turn on the "complete" lamp (green battery indicator) or possibly not being able to

reach a charge level to turn on the "complete" indicator.
14) If the magnet was left on and the battery allowed to drop below 8 volts, the magnet's power relay
could remain latched "ON" even if the RELEASE buttons on the I.R. remote were pressed. Under
�his condition, the magnet coil would load down the battery preventing it from being charged. The
solution is to disconnect the battery and charge it with an external charger. When the battery is
reconnected, the circuit will reset itself.
5) Check the output of the charger. This can be done by a qualified electrician using an amp meter
(capable of handling 10 amps) connected in series between the (red) positive battery cable and the
po) terminal battery. Read section (I).
1) When the power cord is connected to a 115VAC power source, the red battery indicator light
should turn on within 10 seconds to indicate the battery is being charged. As the battery nears a
�ull charge, the battery indicator will alternate between red and green. When the battery is fully
charged, the indicator will stay green, indicating a float charge (13.5 volts) is being maintained on
�he battery and that the magnet is ready for use. The charge time will vary depending upon the
I. DISPLAY LAMPS state of the battery when the charge is initiated.
DO NOT TURN ON 2) If the battery indicator does not light when the charger is initially plugged in and the magnet is
WHILE CHARGING. �urned off, then the battery level may have fallen too low and the battery charger will not operate.
Check the battery voltage. If the voltage has fallen below approximately 8 volts, the charger may
not turn on immediately. If it doesn't turn on within a few minutes, then the battery may be worn out.
We suggest replacing the battery or charging it with an external charger, then carefully watching its
performance. If the lamps turn off rapidly as discussed in section (C), REPLACE THE BATTERY.
