USING THE ENGINE START FEATURE
Your battery charger can be used to jump start your car if the battery is low. Follow all safety instructions
and precautions for charging your battery. Wear complete eye protection and protective clothing.
WARNING: Using the ENGINE START feature WITHOUT a battery installed in the vehicle could cause
damage to the vehicle's electrical system.
NOTE: If you have charged the battery and it still will not start your car, do not use the Engine Start
feature, or it could damage the vehicle's electrical system. Have the battery checked.
1. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in Follow These Steps When Battery Is Installed In Vehicle.
2. Plug the charger AC power cord into the AC outlet.
3. With the charger plugged in and connected to the battery and chassis, select the Engine Start rate. If
the battery is properly connected, the yellow/orange Engine Start LED will light solid and the display
will show "ON". If display shows "0.0", check the battery connections. If the display does not show "On",
check the battery connections. When the Engine Start output is enabled the display will show "rdy".
4. Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait a few minutes before
cranking again. This allows the charger and battery to cool down. NOTE: During extremely cold
weather, or if the battery is under 2 volts, boost the battery for 5 minutes before cranking the engine.
NOTE: After 3 minutes in Engine Start mode, the charger will enter into a cool-down period of 180
seconds, to allow the charger and the battery to cool down. The digital display indicates the remaining
cool down time in seconds. It starts at 180 and counts down to 0. After 3 minutes, the digital display will
change from displaying the countdown to displaying "rdy".
5. If the engine fails to start, use the Boost rate for 5 more minutes before attempting to crank the engine again.
6. After the engine starts, unplug the AC power cord before disconnecting the battery clamps from the vehicle.
7. Clean and store the charger in a dry location.
NOTE: If the engine does turn over but never starts, there is not a problem with the starting system;
there is a problem somewhere else with the vehicle. STOP cranking the engine until the other problem
has been diagnosed and corrected.
TESTER AND CHARGER
When first turned on, the unit operates only as a tester, not as a charger. Selecting a charge rate activates
the battery charger and deactivates the tester. Pressing the Rate Selection button when the Engine Start
LED is lit (except during the 180 second cool down) will shut off the charger and activate the tester.
USING THE BATTERY VOLTAGE TESTER
1. With the charger unplugged from the AC outlet, connect the charger to the battery, following the
instructions given in previous sections.
2. Plug the charger AC power cord into the AC outlet.
3. Press the Battery Type button until the correct type is indicated.
4. Read the voltage on the digital display. Keep in mind that this reading is only a battery voltage reading;
a false surface charge may mislead you. Compare the reading to the following chart.
6V Battery Voltage
Reading
6.4 or more
6.1 to 6.3
Less than 6.1
POWER-UP IDLE TIME LIMIT
If no button is pressed within 10 minutes after the battery charger is first powered up, the charger will
automatically switch from tester to charger if a battery is connected. In that case, the charger will be set to
the Boost rate and AGM battery type.
TESTING AFTER CHARGING
After the unit has been changed from tester to charger (by selecting a desired rate), it remains a charger. To
change the battery charger back to a tester, press the Rate Selection button until all rate LEDs are off.
NOTE: The battery tester is only designed to test batteries. Testing a device with a rapidly changing
voltage could yield unexpected or inaccurate results.
