Clore Automotive Booster Pac ES400, Operator'S Manual

WARNING

Read these instructions completely before using the 

J900 and save them for future 

reference. Before using the 

J900 to jump start a car, truck, boat or to power any 

equipment, read these instructions and the instruction manual/safety information 
provided by the car, truck, boat or equipment manufacturer. Following all manufacturers’ 
instructions and safety procedures will reduce the risk of accident.

Working around lead-acid batteries may be dangerous. Lead-acid batteries release 
explosive gases during normal operation, charging and jump starting. Carefully read and 
follow these instructions for safe use. Always follow the specific instructions in this 
manual and on the 

J900 each time you jump start using the J900.

All lead-acid batteries (car, truck and boat) produce hydrogen gas which may violently 
explode in the presence of fire or sparks. 

Do not smoke, use matches or a cigarette 

lighter while near batteries. Do not handle the battery while wearing vinyl clothing 
because static electricity sparks are generated when vinyl clothing is rubbed. Review all 
cautionary material on the 

J900 and in the engine compartment.

Always wear eye protection, appropriate protective clothing and other safety equipment 
when working near lead-acid batteries. Do not touch eyes while working on or around 
lead-acid batteries.

Always store clamps in their holsters, away from each other or common conductors. 
Improper storage of clamps may cause the clamps to come in contact with each other, 
or a common conductor, causing the battery to short circuit and generate high enough 
heat to ignite most materials.

Use extreme care while working within the engine compartment, because moving parts 
may cause severe injury. Read and follow all safety instructions published in the vehicle's 
Owner's Manual.

While the battery in the 

J900 is a sealed unit with no free liquid acid, batteries being jump 

started with the 

J900 unit likely contain liquid acids which are hazardous if spilled.

Failure to follow instructions may 

cause damage or explosion, 

always shield eyes. 

Read entire 

instruction manual before use.
