To attach the axle assembly: 11.1 Remove charger from packing materials and place upside down on a flat surface. Attach mounting foot and secure with the four, 1/4-20 thread cutting screws. 11.2 Hold axle upright on floor or work surface. Then, using a hammer, tap one of the plastic axle caps onto the top end of the axle. Be sure to tap the axle cap on straight. Slide both wheels onto the axle with the axle caps facing each other.
11.3 Place the charger on its side. Place one end of each bracket into slot, then place the axle assembly under each bracket. Fasten the other side of the brackets using the two, 10-32 screws provided. 11.4 To Attach Handle: Turn the charger right side up onto its foot and wheels. Remove the two top screws from each side of the charger. Align the handle so the screw holes are aligned with the screw holes on each side of the wheel charger. Attach the handle using the same screws.
12. using the gfci outlet This charger includes two – GFCI (Ground Fault Circuit Interrupter) outlets located on its back. The purpose of a GFCI outlet is to quickly stop the flow of electricity in the event a ground fault occurs on the device plugged into the battery charger’s GFCI outlet. Ground fault circuit interrupters (GFCI) can help prevent electrical shock or electrocution. The GFCI outlets provide auxiliary power to 120V devices that require less than 15 amps.
6 VOLT when charging, testing or starting 6 volt systems. 13.3 TOUCH‑PAD CONTROLS With your charger connected to the vehicle and power source, the battery voltage (6 or 12 volt) selected, and the power turned ON, select either AUTOMATIC or MANUAL charge and the rate at which you want to charge your battery (2, 20, or 60 amp). • AUTO (Automatic): When first turned ON, the charger will be in the Manual mode. Touch the AUTO pad and either the 2, 20, or 60 AMP Charge Rate Selector pad.
If you do not set a time, the charger will run for the maximum time. After selecting the charge rate and proper time, the charger will start charging after a short delay. To see how much time remains during the charging process, touch the TIME pad. • RESET: To stop charging or to change settings once charging has begun, touch the RESET pad. Then proceed as if you’ve just turned on the charger. • VOLT/AMP: When the charger is turned on the METER will display battery voltage.

will be charged to 100 percent needs another 50 percent (.50)). • Multiply the Amp Hour rating by the charge needed (.50) and divide by the charger setting (2 or 10 amps). • Multiply the result by 1.25 and you’ll have the approximate time needed, in hours, to bring the battery to full charge. • Add one additional hour for a deep-cycle battery. Example: Amp Hour Rating x charge needed Charger Setting x 100 (AH Rating) x .50 (charge needed) x 50 (Charger Setting) 1.25 = 1.25 = hours of charge 6.
Important: Do not try to start the engine without a battery in it. You could cause damage to the electrical system. If the engine does turn over, but never starts up, 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. NOTE: The GFCI outlet should not be used while the Charger is in the Engine Start Mode. 16. maintenance instructions 16.
18. troubleshooting PROBLEM POSSIBLE CAUSE SOLUTION/REASONS No reading on the ammeter. Clamps are not making a good connection. Check for poor connections to battery and frame. Make sure connecting points are clean. 2-amp charge rate is being used. Ammeter may show no activity at the 2-amp charge rate. Drawing more than 250 amps for a period of 3 seconds or less. Crank time varies with the amount of current drawn. If cranking draws more than 250 amps, crank time may be less than 3 seconds.
