Make sure that the charger cable clips make tight connections.

3.11 

CHARGER LOCATION

4.

Risk of explosion and contact with 

battery acid.

Locate the charger as far away from the battery as the DC cables permit.

4.1 

Never place the charger directly above the battery being charged; gases from 

4.2 

the battery will corrode and damage the charger.
Do not set the battery on top of the charger.

4.3 

Never allow battery acid to drip onto the charger when reading the electrolyte 

4.4 

specific gravity or filling the battery.

Do not operate the charger in a closed-in area or restrict the ventilation in any 

4.5 

way.

DC CONNECTION PRECAUTIONS

5.

Connect and disconnect the DC output clips only after setting all of the charger 

5.1 

switches to the “off” position and removing the AC plug from the electrical

outlet. Never allow the clips to touch each other.
Attach the clips to the battery and chassis, as indicated in sections 6 and 7.

5.2 

FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE.

6.

A spark near the battery may cause 

a battery explosion. To reduce the 

risk of a spark near the battery:

Position the AC and DC cables to reduce the risk of damage by the hood, door 

6.1 

and moving or hot engine parts. NOTE: If it is necessary to close the hood 

during the charging process, ensure that the hood does not touch the metal 

part of the battery clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.

6.2 

Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post 

6.3 

usually has a larger diameter then the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chassis. 

6.4 

If the negative post is grounded to the chassis (as in most vehicles), see step 

6.5. If the positive post is grounded to the chassis, see step 6.6.
For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the 

6.5 

battery charger to the POSITIVE (POS, P, +) ungrounded post of the battery. 

Connect the NEGATIVE (BLACK) clip to the vehicle chassis or engine block 

away from the battery. Do not connect the clip to the carburetor, fuel lines or 

sheet-metal body parts. Connect to a heavy gauge metal part of the frame or 

engine block.
