Operating Instructions - Schumacher Electric DSR116 Owner's Manual

Maintain Mode (Float Mode Monitoring)
When the internal battery is fully charged and the jump starter display shows "100", the charger has
started maintain mode. In this mode, the charger keeps the battery fully charged by delivering a small
current when necessary. If the charger has to provide its maximum maintain current for a continuous
12 hour period, it will go into abort mode (see Aborted Charge). This is usually an indication of a bad
battery; have the jump starter checked.
Charging the Internal Battery While Driving
5.4
You may also charge the internal battery while driving, using a male-to-male charger cable (part number
94500109 – sold separately).
IMPORTANT: WHEN USING A 12V PORT CHARGING CABLE, DO NOT CHARGE THE INTERNAL
BATTERY FOR MORE THAN 30 MINUTES OR LEAVE THE BATTERY UNATTENDED. IT COULD
EXPLODE, CAUSING PROPERTY DAMAGE OR PERSONAL INJURY.
1. Make sure the car is running.
2. Insert one end of the accessory cable into the 12V DC power outlet.
3. Insert the other end of the accessory cable into the vehicle's accessory outlet (lighter socket).
NOTE: Using this method to charge the battery overrides the maintain mode and the battery can be overcharged.
4. Monitor the progress of the charge by pressing the Percentage of Charge button on the front of the unit.
Do not leave the battery unattended or it could explode, causing property damage and personal injury.
When the battery is fully charged, disconnect the accessory cable from the jump starter, and then from the
lighter socket of the vehicle.
NOTE: Completely disconnect the charger cable when the engine is not running.

OPERATING INSTRUCTIONS

Jump Starting a Vehicle Engine
6.1
IMPORTANT: Using the jump starter without a battery installed in the vehicle will damage the vehicle's
electrical system.
IMPORTANT: Do not use the jump starter while charging its internal battery.
1. Turn the vehicle's ignition OFF before making cable connections.
2. Make sure the rotary switch on the front of the jump starter is in the OFF position. Connect the jump
starter to the battery, following the precautions listed in section 3.
WARNING! RISK OF EXPLOSION.
If you have connected the clips backward, an audio alarm will sound. DO NOT turn the rotary switch
to the 12V position. This could cause serious damage to the jump starter or the vehicle. Reverse the
connections and the audio alarm will stop.
3. If no audio alarm sounds, turn the rotary switch to the 12V position. The clips are now powered.
4. Crank the engine. If the engine does not start within 3-8 seconds, stop cranking and wait at least 1
minute before attempting to start the vehicle again. (This permits the battery to cool down.)
5. After the engine starts, turn the rotary switch to the OFF position. Disconnect the black clip (-), then the
red clip (+) in that order, and clip them back onto the jump starter storage holders.
6. Recharge the jump starter as soon as possible after use.
NOTE: If the cables are connected to a 24 volt system when the switch is in the 12 volt position, the audio
alarm will sound continuously. TURN OFF the jump starter immediately or internal battery damage could occur.
WARNING! RISK OF EXPLOSION.
To prevent sparking, NEVER allow the clips to touch together or to contact the same piece of metal.
Never attempt to jump start a frozen battery.
Powering A 12V DC Device:
6.2
The jump starter is a power source for all 12V DC accessories that are equipped with a 12V accessory plug.
Use it for power outages and fishing or camping trips. Estimated usage time is listed in the following chart.
1. Make sure the device to be powered is OFF before inserting a 12V DC accessory plug into the
12V DC socket.
2. Ensure the battery clips are securely clipped on the storage holders.
3. Open the protective cover of the 12V DC power outlet on the front of the jump starter.
4. Plug the 12V DC device into the 12V DC power outlet, and turn the 12V DC device on (if required).
