5.4. FUNCTION SELECTION BUTTON
FUNCTION
Mode Explanation
CHARGE The operating mode of the charger is charging mode.
SUPPLY Provide a stable output to help the equipment work normally and
check and repair..
REPAIR Provide a positive pulse voltage to charge the battery that has been
idle for a long time or the dead battery.
5.5. CURRENT SELECTION BUTTON BATTERY VOLTAGE SELECTION BUTTON
5.6. ENGINE START BUTTON
ENGINE START (press ENGINE START BUTTON to enter) – Provides additional amps for cranking an engine with a weak or
run-down battery.
WARNING: Always use in combination with a battery. Must NOT touch or disconnect clamps when ENGINE START mode works,
otherwise there may be serious injuries to people or property.
5.7. CONNECTING TO THE BATTERY
5.7.1. Identify polarity of battery posts. The positive battery terminal is typically marked by these letters or symbol (POS, P, +). The negative
battery terminal is typically marked by these letters or symbol (NEG, N, –).
8 DO NOT make any connections to the carburetor, fuel lines, or thin metal parts.
5.7.2. Identify if you have a negative or positive grounded vehicle. This can be done by identifying which battery post (NEG or POS) is
connected to the chassis.
5.7.3. For a negative grounded vehicle (most common): connect the RED POSITIVE clamp rst to the positive battery terminal, then connect
the BLACK NEGATIVE clamp to the negative battery terminal or vehicle chassis.
5.7.4. For a positive grounded vehicle (very uncommon): connect the BLACK NEGATIVE clamp rst to the negative battery terminal, then
connect the RED POSITIVE clamp to the positive battery terminal or vehicle chassis.
5.7.5. When disconnecting, disconnect in the reverse sequence, removing the negative rst (or positive rst for positive ground systems).
5.7.6. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for
marine use.

5.8. OPERATING STEPS
5.9. ENGINE START FUNCTION
5.9.1. 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. The procedures are as follows.
PROCEDURE CONNECTION SELECTION KEY
Step 1 Ensure battery connection. Digital display:Connected battery
voltage
Step 2 Start machine.
Step 3 Select the engine start button and
set the start time.
Step 4 Stop or start the operation.
Warning: Using the ENGINE START feature WITHOUT a battery installed in the vehicle will damage the vehicle’s electrical system.
5.9.2. 1. With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in the connecting to
the battery 5.7section.
5.9.3. 2. Plug the charger AC power cord into the AC outlet. With the charger plugged in and connected to the battery and chassis, press the
ENGINE START button until the ENGINE START LED is lit.
NOTE: During extremely cold weather, or if the battery is under 2 volts, charge the battery for 5 minutes before cranking the engine.
5.9.4. Crank the engine until it starts or 3 seconds pass. If the engine does not start, wait 3 minutes before cranking again. This allows the
charger and battery to cool down.
5.9.5. If the engine fails to start, use the BOOST rate to charge for 5 minutes before attempting to crank the engine again.
5.9.6. After the engine starts, unplug the AC power cord before disconnecting the battery clamps from the vehicle.
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. During the starting
sequence listed above, the charger is set to one of three states:
5.9.7. Wait for cranking – While waiting for cranking, the digital display shows START-READY. The charger waits until the engine is actually
being cranked before delivering the amps for engine start. Press the remote button before cranking the engine immediately. If the
remote is not used, the charger will automatically detect whether engine is trying to crank.
5.9.8. Cranking – When cranking is detected, the charger will automatically deliver up to its maximum output as required by the starting
system for up to 5 times (15)seconds.
5.9.9. Cool Down – After cranking, the charger enters a mandatory 240 seconds cool down state. The remote or any button does NOT
work. The digital display indicates the remaining cool down time in seconds. It starts at 240 and counts down to 0. After 4 minutes,
the digital display will change from displaying the countdown to displaying START-READY. If using the engine starter again, please
continue to press the remote button.
5.10. VOLTAGE TESTER AND CHARGER
When rst turned on, the unit operates only as a tester, not as a charger.
If the “TEST” function is used, stop the “FUNCTION” and the corresponding working mode is turned o. Then select the “TEST”
button to detect and view the connected battery voltage and Charge level.
NOTE: The battery tester is only designed to test batteries. Testing a device with a rapidly changing voltage could yield unexpected or
inaccurate results.
5.11. ALTERNATOR CHECK
5.11.1. With the charger unplugged from the AC outlet, connect the charger to the battery, following the instructions given in previous sections.
5.11.2. Plug the charger AC power cord into the AC outlet.
5.11.3. Start the vehicle and turn on the vehicle’s headlights. Read the state on the digital display. If you get a reading “0-100%”, the alternator
is working properly. If the reading is “LO” or ”HI” , have the charging system checked by a qualied technician.
NOTE: When rst turned on, the unit operates only as a tester, not as a charger. The charger must stop charging.
