higher charge rate is more suitable for fast
charging a battery to the point where it will
start a vehicle, the lower (slower) charge
rate is more suitable for fully charging
(restoring) a battery. (See the Input/Output
Chart on the Battery Charger.)
VOLTAGE SELECTOR SWITCH
Use this switch to set the scale of the
voltmeter to either 6 volt and 12 volt DC,
to match the battery or batteries being
charged. NOTE: This does not change the
output voltage of the charger.
BATTERY LOAD TESTER SWITCH
(Model PSW-3060 only)
Use this switch to apply a load to the
battery when testing it. (See Using the
Battery Load Tester Feature.)
TIMER
The timer allows you to set a specified
time for charging. After the timer expires,
the charger stops charging your battery.
The main function of the timer is to
prevent over charging while allowing
a battery time to obtain a satisfactory
charge. To properly set the timer, you
must know the size of the battery in
ampere hours or reserve capacity in
minutes and the state of charge.
It is important that you determine the
appropriate state of charge of your
battery and set the timer accordingly.
Hold – This position defeats the timer
function, allowing for continuous
operation. Put the timer in the HOLD
position when you want to charge more
than 2¼ hours. Be sure to monitor the

12. OPERATING INSTRUCTIONS

WARNING: A spark near battery may
cause an explosion.
CHARGING A BATTERY
IN THE VEHICLE
1. Turn off all the vehicle's accessories.
2. Keep the hood open.
3. Clean the battery terminals.
4. Set the charge rate selector switch
and the timer to the OFF position.
5. Lay the AC/DC cables away from any
fan blades, belts, pulleys and other
moving parts that can cause injury.
6. Connect the battery, following the
precautions listed in sections 6 and 7.
7. Connect the charger to an electrical
outlet.
8. Set the voltage selector switch (if
equipped) to the correct voltage for
the battery type you are charging.
9. Select the desired charge rate.
charging progress and stop it when the
battery is charged. Not doing so may
cause damage to your battery or may
cause other personal property damage or
personal injury.
AMMETER
The Ammeter indicates the amount of
current, measured in amps, that is being
drawn by the battery. As a battery takes
on a charge, it draws less current from
the charger. Correspondingly, the meter
will show less current being drawn by the
battery. When the current stops decreasing,
the battery is charged. The 2 amp charge
rate may indicate some activity on the
meter, although the meter does not have
the resolution to display this low rate.
VOLTMETER
The voltmeter indicates the voltage at
the battery terminals. The charger need
not be plugged into an AC outlet. The
timer should be in the OFF position.
Then connect the charger following the
instructions in sections 6 and 7. Observe
the meter indication. Keep in mind that this
reading is only a battery voltage reading, a
false surface charge may mislead you. We
suggest that you turn on the headlights
for a couple of minutes before you read
the meter. Read it a couple of minutes
after you have shut the headlights off. If
the reading is less than 10.5-volts, the
battery may be bad or the connection at
the charger may be poor. If the reading
is 10.5-volts to 12.8-volts, the battery is
low – recharge it. If the reading is above
12.8-volts, the battery is charged.
10. Set the timer to the desired charge
time. MONITOR THE CHARGER
AND THE BATTERY.
11. When disconnecting the charger, set
the charge rate switch and the timer
to the OFF position, disconnect the
charger from the AC power, remove
the clamp from the vehicle chassis,
and then remove the clamp from the
battery terminal.
CHARGING A BATTERY
OUTSIDE OF THE VEHICLE
1. Place battery in a well-ventilated area.
2. Set the charge rate switch and the
timer to the OFF position.
3. Clean the battery terminals.
4. Connect the battery, following the
precautions listed in sections 6 and 7.
5. Connect the charger to the electrical
outlet.
