MAINTENANCE INSTRUCTIONS

13.1
After use and before performing maintenance, unplug and disconnect the battery
charger (see sections 5, 6 and 7).
13.2 Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clips,
cords and the charger case.
13.3 Ensure that all of the charger components are in place and in good working condition,
for example, the plastic boots on the battery clips.
13.4 Servicing does not require opening the unit, as there are no user-serviceable parts.
13.5 All other servicing should be performed by qualified service personnel.
14. STORAGE INSTRUCTIONS
14.1 Store the charger unplugged, in an upright position. The cord will still conduct electricity
until it is unplugged from the outlet.
14.2 If the charger is moved around the shop or transported to another location, take care to
avoid/prevent damage to the cords, clips and charger. Failure to do so could result in
personal injury or property damage. Store the clips on the fiberglass clamp rod. Do not
store them on the handle, clipped together, on or around metal, or clipped to the cables.

TROUBLESHOOTING

PROBLEM
No reading on the
ammeter.
Ammeter reading
stays high.
Ammeter reads
less than selected
charge rate
when charging a
discharged battery
Battery clips do not
spark when touched
together.
Downloaded from www.Manualslib.com
POSSIBLE CAUSE
Charger is not plugged in.
No power at the receptacle.
Clips are not making a good
connection to the battery.
Connections are reversed.
Battery is defective (will not
accept a charge).
4 amp charge rate is being used.
Battery is severely discharged.
Extension cord is too long or
wire gauge is too small.
Weak cell or sulfated plate in
battery.
Battery is only partially
discharged.
The charger is equipped with
a safe start feature. In the
automatic modes, it will not
supply current to the battery
clips until a battery is properly
connected. Unlike traditional
chargers, the clips will not spark
if touched together. (In manual
mode, the clips should spark.)

REASON/SOLUTION
Plug the charger into an AC outlet.
Check for open fuse or circuit breaker
supplying AC outlet.
Check for poor connection to battery and
frame. Make sure connection points are
clean. Rock clips back and forth for a
better connection.
Unplug the charger and reverse the clips.
Have battery checked.
Ammeter may show no activity at the 4A
charge rate.
Continue charging battery for two more
hours. If problem continues, have the
battery checked.
Use a shorter or heavier gauge extension
cord.
A sulfated battery will eventually take a
normal charge if left connected. If the
battery will not take a charge, have it
checked.
Continue to charge the battery.
No problem; this is a normal condition.
