Charging Modes. The MW LF-CC008A has three (3) modes. The Lithium charge mode require the mode button to be pressed and held
for three (3) seconds to enter the enhanced mode. This "Enhanced" modes require your full attention before selecting. Do not operate the
charger until you confirm the appropriate charge mode for your battery. Below is a brief description:

PREPARING TO CHARGE

a) If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all
accessories in the vehicle are off, so as not to cause an arc.
b) Be sure area around battery is well ventilated while battery is being charged.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d) Study all battery manufacturer's specific precautions while charging and recommended rates of charge.
e) Determine voltage of battery by referring to car owner's manual and make sure that the output voltage selector switch is set at
correct voltage. If charger has adjustable charge rate, charge battery initially at lowest rate.

CONNECTING TO BATTERY

a) Set any charger switches to "off" position and remove ac cord from electric outlet before connecting or disconnecting DC
output clamps or eyelets. Never allow clamps or eyelets to touch each other.
b) Identify the correct polarity of the battery terminals. The positive battery terminal is typically marked with (POS, P, +). The
negative terminal is typically marked with (NEG, N, -).
c) Position cords and cables to reduce risk of damage by hood, door or moving parts (including fan blades, belts, and pulleys)
or other parts that could cause injury to persons.
d) Do not connect to carburetor, fuel lines, or sheet-metal body parts.
e) Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to the chassis (as in
most vehicles) see (f). If positive post is grounded to the chassis, see (g).
f) For Negative-grounded vehicle, connect POSITIVE (RED) clamp from battery charger to POSITIVE (POS, P, +) post of
battery. Connect NEGATIVE (BLACK) from battery charger to the NEGATIVE (NEG, N, -) post of battery.
g) For Positive grounded vehicle, connect NEGATIVE (BLACK) from battery charger to NEGATIVE (NEG, N, –) post of
battery. Connect POSITIVE (RED) clamp from battery charger to the POSITIVE (POS, P, +) post of battery.
h) When disconnecting charger, turn switches to off, disconnect AC cord, remove connectors in reverse sequence from
connecting procedure.
