Charger Location
1. Locate charger as far away from battery as cables permit.
2. NEVER place charger directly above battery being charged; gases from battery will corrode and damage charger.
3. NEVER allow battery acid to drip on charger when reading gravity or filling battery.
4. NEVER operate charger in a closed-in area or restrict ventilation in any way.
5. Marine batteries must be removed and charged on shore.
6. Do not set a battery on top of charger.
Charger Clamp Connection Precautions
1. Connect and disconnect clamps only after removing AC cord from electric outlet.
2. Never allow clamps to touch each other.
3. Attach clamps to battery and chassis as indicated in "Battery Installed in Vehicle" steps 5 and 6, and in "Battery Outside of
Vehicle" steps 2, 4 and 5.
CAUTION: A spark near the battery may cause an explosion. Follow these steps to reduce the risk of a spark near the
battery when the battery is installed in a vehicle:
1. Position AC and clamp cords away from hood, door, or moving engine parts.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N, –)
post.
4. Determine which post of battery is grounded (connected) to the chassis. If NEGATIVE post is grounded to chassis (as in
most vehicles), see 5. If POSITIVE post is grounded to the chassis, see 6.
5. For negative-grounded vehicle, connect POSITIVE (RED) clamp from battery charger to POSITIVE (POS, P, +) ungrounded
post of battery. Connect NEGATIVE (BLACK) clamp to vehicle chassis or engine block away from battery. Do not connect clip
to carburetor, fuel lines, or sheet-metal body parts. Connect to heavy gauge metal part of the frame or engine block.
6. For positive-grounded vehicle, connect NEGATIVE (BLACK) clamp from battery charger to NEGATIVE (NEG, N, –)
ungrounded post of battery. Connect POSITIVE (RED) clamp to vehicle chassis or engine block away from battery. Do not
connect clip to carburetor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine
block.
7. When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery
terminal.
8. Do not charge the battery while the engine is operating.
9. See operating instructions for length of charge information.
CAUTION: A spark near the battery may cause an explosion. Follow these steps to reduce the risk of a spark near the battery
when the battery has been removed from a vehicle:
1. Check polarity of battery posts. Positive post (marked POS,P, +) usually has a larger diameter than the Negative battery post
(marked NEG, N, –).
2. Attach a 24-inch (minimum length) #6 AWG insulated battery cable to the NEGATIVE battery post (marked NEG, N, –).
3. Connect the POSITIVE (RED) battery clamp to the POSITIVE battery post (marked POS, P, + or red).
4. Stand as far back from the battery as possible, and do not face battery when making final connection.
5. Carefully connect the NEGATIVE (BLACK) charger clamp to the free end of the battery cable connected to the NEGATIVE
terminal.
6. Set the charge rate to appropriate setting according to battery size.
7. When disconnecting charger, always do so in reverse sequence of connecting procedure and break first connection while as
far away from battery as practical.
Note: A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially
designed for marine use. This unit is NOT designed for such use.

Controls and Functions
CHARGING GAUGE
FUNCTION CONTROL KNOB
The Function Control Knob is used to select either the Smart Charge or Alternator Check function. This selection must be made
BEFORE connecting the battery charger clamps to the battery.
Smart Charge analyzes the battery and starts the recharging process.
Alternator Check checks to determine that the alternator is keeping up with the electrical load.
SCROLLING MESSAGE LCD DISPLAY
The Scrolling Message LCD Display (LCD) indicates the various status messages and/or conditions as described in the Smart
Charge Function and Alternator Check sections that follow.
CHARGING GAUGE
The Charging Gauge displays the percentage of charge during the Smart Charge process.
SETTING UP THE UNIT
Ensure that all installation and operating instructions and safety precautions are understood and carefully followed by anyone
installing or using the charger. Follow the steps outlined in the "Important Safety Instructions" section of this manual.
After turning the Function Control Knob to the desired function position, plug the charger into a functioning 120 volt AC outlet.
