correct polarity of the battery terminals on the battery. 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,-). Do not make any connections to the carburetor, fuel lines, or
thin, sheet metal parts. The instructions bellow are for a negative ground system (most common). If your vehicle is a positive ground system (very
uncommon), follow the instructions below in reverse order.
1.) Securely connect the negative (black) Boost Max Connector to the negative port on the GB500.
2.) Securely connect the positive (red) Boost Max Connector to the positive port on the GB500.
3.) Always clean terminals prior to connecting the clamps. NOTE: Faulty connections or dirty terminals may cause smoke. Batteries with very low
voltage will also increase the chance of smoke.
4.) Connect the positive (red) Boost Max Connector the positive (POS,P,+) battery terminal.
5.) Connect the negative (black) Boost Max Connector to the negative (NEG,N,-) battery terminal or vehicle chassis. Ensure both clamps have a
secure connection. (Grounding to the chassis may not be suitable for jump starting large applications.)
6.) When disconnecting, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).
Step 3: Jump Starting.
1.) Make sure all of the vehicle's power loads (headlights, radio, air conditioning, etc.) are turned "Off" before attempting to jump start the vehicle. If the
vehicle is equipped with a Master Switch, turn it to the "on" position.
2.) Press the Power Button to begin jump starting. All LEDs will flash, indicating that all LEDs are properly functioning. If you are properly connected to
the battery, the White Boost LED will illuminate and the 25%-100% LEDs will chase.
3.) Try starting the vehicle. Most vehicles will immediately start. Some vehicles may require the GB500 to be connected for up to thirty (30) seconds
before starting. If the vehicle does not start right away, wait 20-30 seconds and try again. Do not attempt more than five (5) consecutive jump starts
within a fifteen (15) minute period. Allow the GB500 to rest for fifteen (15) minutes before attempting to jump start the vehicle again.
4.) Once you have started your vehicle, disconnect the battery clamps, and remove the GB500.
Low Voltage Batteries & Manual Override.
The GB500 is designed to jump start batteries down to 2-volts. If your battery is below 2-volts, the Boost LED will be "Off". This is an indication that
the GB500 can not detect a battery. If you need to jump start a battery below 2-volts there is a Manual Override feature, which allows you to force
"On" the jump start function.
CAUTION.
USE THIS MODE WITH EXTREME CARE. THIS MODE IS FOR 12-VOLT OR 24-VOLT LEAD-ACID BATTERIES ONLY. ENSURE THE VOLTAGE
SELECTION KNOB IS IN THE CORRECT POSITION (12V OR 24V) MATCHING THE BATTERY SYSTEM BEING JUMP STARTED. BOTH THE SPARK
PROOF AND REVERSE POLARITY PROTECTION FEATURES ARE DISABLED. PAY VERY CLOSE ATTENTION TO THE POLARITY OF THE BATTERY
BEFORE USING THIS MODE. DO NOT ALLOW THE POSITIVE AND NEGATIVE BATTERY CLAMPS TO TOUCH OR CONNECT TO EACH OTHER
AS THE PRODUCT WILL GENERATE SPARKS. THIS MODE USES VERY HIGH CURRENT (UP TO 20,000 AMPS) THAT CAN CAUSE SPARKS AND
HIGH HEAT IF NOT USED PROPERLY. IF YOU ARE UNSURE ABOUT USING THIS MODE, DO NOT ATTEMPT AND SEEK PROFESSIONAL HELP.
