14. MAINTENANCE, CARE AND STORAGE
A minimal amount of care can keep your battery charger
working properly for years.
1. After each use, unplug unit, wipe all battery corrosion and
other dirt or oil from clamps, cables and the charger case.
Use a dry cloth.
2. Coil the charger cables to prevent damage. This will
prevent accidental damage to the cables and charger.
3. Have any cracked or frayed cables replaced by an
authorized Snap-on representative.
4. Store the unplugged battery charger in a clean, dry area.
15. TROUBLESHOOTING AND ERROR CODES
Performance problems often result from little things that you can x yourself. Please read through these tables for a
possible solution if a problem occurs.
Error Codes
CODE DESCRIPTION REASON/SOLUTION
F01
The battery voltage is still under 10V (for a 12V battery) or
5V (for a 6V battery) after 2 hours of charging.
The battery could be bad. Have it checked or replaced.
SUL
The charger has detected a sulfated battery.
The charger will go into desulfation mode. If the desulfation is not
successful after 10 hours, the charger will go into abort mode.
F02
The charger cannot desulfate the battery.
The battery could not be desulfated; have it checked or replaced.
F03
The battery was unable to reach the “full charge” voltage.
May be caused by trying to charge a large battery or bank of batteries on
too low of a current setting. Try again with a higher current setting or have
the battery checked or replaced.
F04
The connections to the battery are reversed.
The battery is connected backwards. Unplug the charger and reverse the
connections to the battery.
F05
The charger was unable to keep the battery fully
charged in maintain mode.
The battery won’t hold a charge. May be caused by a drain on the battery or
the battery could be bad. Make sure there are no loads on the battery. If there
are remove them. If there are none, have the battery checked or replaced.
F06
The charger detected that the battery may be getting
too hot (thermal runaway).
The charger automatically shuts the current off if it detects the battery may
be getting too hot. Have the battery checked or replaced.
If you get an error code, check the connections and settings and/or replace the battery.
Troubleshooting
PROBLEM POSSIBLE CAUSE SOLUTION
Charger will not turn on
when properly connected.
AC outlet is dead.
Poor electrical connection.
Battery is defective.
Check for open fuse or circuit breaker supplying AC outlet.
Check power cord and extension cord for loose tting plug.
Have the battery checked.
The Boost/Charge LED is
ashing.
The charger has stopped in Boost or
Charge mode.
The battery is bad.
The charger cannot complete the boost or charge. Have the battery
checked and replace, if necessary.
Disconnect charger from the AC outlet and then remove the clamps. Do
not continue to try to charge the battery. Have the battery checked and
replace, if necessary.
The Boost/Charge LED
does not turn off.
The charger is still in Boost or Charge
mode.
This is normal. The Boost/Charge LED will not turn off until the battery
is disconnected from the charger.
Charger does not detect a
low voltage battery.
The charger was on for more than 5
minutes before it was connected to the
battery.
The clamps are active for only the rst 5 minutes. Switch to the OFF
position and connect the charger to the battery. Set the switch to the
Boost/Charge/Maintain position. Then push the rate selection button to
turn on the charger.
Engine start does
not work.
Drawing more than 200 amps.
Failure to wait 3 minutes (180 seconds)
between cranks.
The charger may be overheated.
Battery may be severely discharged.
Push the rate selection button to choose boost or charge modes, then press
the Start button to start the charging process.
When the Engine Start LED blinks, wait 3 minutes of rest time before
the next crank.
The thermal protector may have tripped and needs a little longer to reset.
Make sure the charger vents are not blocked. Wait and try again.
On a severely discharged battery, use the Boost rate for several minutes,
to help assist in cranking.
