16. DC CONNECTION PRECAUTIONS
a. Connect and disconnect the DC output clamps only after setting the charger switches to the OFF position and removing the AC cord from the
electric outlet. Never allow the clamps to touch each other.
b. Attach the DC clamps to the battery post and twist or rock back and forth several times to make a good connection. This tends to keep the
clamps from slipping off the terminals and helps to reduce the risk of sparking.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE. A SPARK NEAR THE BATTERY
MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
a. Position the AC and DC cords to reduce the risk of damage by the hood, door, or moving engine parts.
b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c.
Check the polarity of the battery post. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, –)
post.
d. Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most
vehicles), see item "e". If the positive post is grounded to the chassis, see item "f".
e. For negative-grounded vehicles, connect the POSITIVE (RED) clamp from the battery charger to the POSITIVE (POS, P, +) ungrounded post
of the battery. Connect the NEGATIVE (BLACK) clamp to the vehicle chassis, heavy gauge metal part of the frame, or engine block, away
from the battery. Do not connect to the carburetor, fuel lines, or sheet metal body parts.
f. For positive-grounded vehicles, connect the NEGATIVE (BLACK) clamp from the battery charger to the NEGATIVE (NEG, N, –) ungrounded
post of the battery. Attach the POSITIVE (RED) clamp to the vehicle chassis or engine block away from the battery. Do not connect the clamp
to the carburetor, fuel lines, or sheet-metal body parts.
g. When disconnecting the charger, turn the switches to OFF, disconnect the AC cord, remove the clamp from the vehicle chassis, and then
remove the clamp from the battery terminal.
h. See the operating instructions for length of charge information.
18.
FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE. A SPARK NEAR THE BATTERY
MAY CAUSE BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
a. Check the polarity of the battery post. The POSITIVE (POS, P, +) usually has a larger diameter than
the NEGATIVE (NEG, N, –) post.
b. Attach at least a 24 inch long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG, N, –)
battery post.
c. Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS, P, +) post of the battery.
d. Position yourself and the free end of the cable as far away from the battery as possible, then connect
the NEGATIVE (BLACK) charger clamp to the free end of cable.
e. Do not face the battery when making the final connection.
f. When disconnecting the charger, always do so in reverse sequence of connecting procedure, and break the first connection while standing as
far away from the battery as practical.
g. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.

GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS
The charger should be grounded to reduce the risk of electric shock. This charger is equipped with an electric cord having an equipment grounding
conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes
and ordinances.
DANGER. Never alter the AC cord or plug provided - if it will not fit the
outlet, have a proper outlet installed by a qualified electrician. Improper
connection can result in a risk of an electric shock. This battery charger is
for use on a nominal 120-volt circuit, and has a grounding plug that looks
like the plug illustrated in FIGURE (A). A temporary adapter, which looks
like the adapter illustrated in FIGURE (C), may be used to connect this plug
to a two-pole receptacle, as shown in FIGURE (B), until a properly grounded outlet can be installed by a qualified electrician.
DANGER. Before using an adapter as illustrated, be certain that the center screw of the outlet plate is grounded. The green-colored rigid ear or
lug extending from the adapter must be connected to a properly grounded outlet - make certain it is grounded. If necessary, replace the original
outlet cover plate screw with a longer screw that will secure the adapter ear or lug to the outlet cover plate and make ground connection to grounded
outlet.
NOTE: USE OF AN ADAPTER IS NOT ALLOWED IN CANADA. IF A GROUNDING TYPE RECEPTACLE IS NOT AVAILABLE, DO NOT USE
THIS APPLIANCE UNTIL THE PROPER OUTLET IS INSTALLED BY A QUALIFIED ELECTRICIAN.
20.
NOTE: SIDE TERMINAL TO BE USED IN POSITIVE CLAMP ONLY! For instructions for NEGATIVE clamp attachment refer to
section 17e or 17f.
Storage position
Will not get lost. Always ready to use.
Extended position
Note: Pressure, when handle is squeezed,
holds adapter firm. Will not slip back.
Thrust on terminal
Note: Clamp is released and spring
tension holds adapter firm.
