IMPORTANT SAFETY INSTRUCTIONS

1. 

Risk of electric shock or fire.

Keep out of reach of children.

1.1 

Use only recommended attachments. Use of an attachment not recommended 

1.2 

or sold by Schumacher® Electric Corporation may result in a risk of fire, 

electric shock or injury to persons or damage to property.
To reduce the risk of damage to the electric plug or cord, pull by the plug rather 

1.3 

than the cord when disconnecting the charger.
An extension cord should not be used unless absolutely necessary. Use of an 

1.4 

improper extension cord could result in a risk of fire and electric shock. If an 

extension cord must be used, make sure:

That the pins on the plug of the extension cord are the same number, size

and shape as those of the plug on the charger.
That the extension cord is properly wired and in good electrical condition.

That the wire size is large enough for the AC ampere rating of the charger

as specified in Section 8.

To reduce the risk of electric shock, unplug the charger from the outlet before 

1.5 

attempting any maintenance or cleaning. Simply turning off the controls will not 

reduce this risk.
Remove personal metal items such as rings, bracelets, necklaces and watches 

1.6 

when working with a lead-acid battery. A lead-acid battery can produce a short-

circuit current high enough to weld a ring or the like to metal, causing a severe 

burn.

Do not operate the charger with a damaged cord or plug; take it to a qualified 

1.7 

service person.
Do not operate the charger if it has received a sharp blow, been dropped or 

1.8 

otherwise damaged in any way; take it to a qualified service person. 

Do not disassemble the charger; take it to a qualified service person when 

1.9 

service or repair is required. Incorrect reassembly may result in a risk of fire 

or 

electric shock. 

PERSONAL PRECAUTIONS

2.

Risk of explosive gases.

Working in the vicinity of a lead-acid battery is dangerous. Batteries generate 

2.1 

explosive gases during normal battery operation. For this reason, it is of 

utmost importance that you follow the instructions each time you use the 

charger.
To reduce the risk of a battery explosion, follow these instructions and those 

2.2 

published by the battery manufacturer and the manufacturer of any equipment 

you intend to use in the vicinity of the battery. Review the cautionary markings 

on these products and on the engine.
