Schumacher SE-4225 owner manual Follow These Steps When Battery is Outside Vehicle

6.6For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the POSITIVE (RED) 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.

6.7When disconnecting the charger, turn all switches to off, disconnect the AC cord, remove the clip from the vehicle chassis and then remove the clip from the battery terminal.

6.8See CALCULATING CHARGE TIME for length of charge information.

7.FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE.

A spark near the battery may cause a battery explosion. To reduce the risk of a spark near the battery:

7.1Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.

7.2Attach at least a 24-inch (61 cm) long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG, N, -) battery post.

7.3Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post of the battery.

7.4Position yourself and the free end of the cable you previously attached to the NEGATIVE (NEG, N, -) battery post as far away from the battery as possible – then connect the NEGATIVE (BLACK) charger clip to the free end of the cable.

7.5Do not face the battery when making the final connection.

7.6When disconnecting the charger, always do so in the reverse order of the connecting procedure and break the first connection while as far away from the battery as practical.

7.7A marine (boat) battery must be removed and charged on shore. To charge it onboard requires equipment specially designed for marine use.

8.BATTERY CHARGING – AC CONNECTIONS

Risk of electric shock or fire.

8.1This battery charger is for use on a nominal 120-volt circuit and has a grounded plug that looks like the plug illustrated. The charger must be grounded to reduce the risk of electric shock. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. The plug pins must fit the receptacle (outlet). Do not use with an ungrounded system.

8.2Never alter AC cord or plug provided – if it does not fit the outlet, have proper grounded outlet installed by a qualified electrician. Improper connection can result in a risk of an electric shock or electrocution.
