WARNING: Fire hazard
The jump start feature is designed for short term operation only- less than 5
seconds. Operating the jump start feature for more than 5 seconds may
cause damage to the unit. Allow the power pack to cool down for at least 3
minutes after each jump start.
WARNING: Risk of explosion, fire or burns
The battery terminals exposed at the jump start cable port have enough
energy present to cause a spark, creating an explosion hazard, or to cause
burns if a metal object contacts both terminals. Always clip the plastic guard
over the port when not in use.
CAUTION: Equipment damage
Do not expose the power pack to temperatures over 104° F(40° C) or under
14° F(-10° C).
Precautions when working with batteries
WARNING: Explosion and fire hazard
1. Follow all instructions published by the battery manufacturer and the
manufacturer of the equipment in which the battery is installed.
2. Make sure the area around the battery is well-ventilated.
3. Never smoke or allow a spark or flame in vicinity of the engine or
batteries.
4. Be careful not to drop a metal object on the battery or allow a metal tool
to simultaneously touch the positive and negative cable ends or battery
terminals. It might spark or short-circuit the battery or other electrical
parts and cause an explosion.
5. Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with batteries. Batteries produce a short-circuit
current high enough to weld a ring or other similar objects to metal,
causing a severe burn.
6. If you need to remove a battery, always remove the negative terminal
from the battery first. Make sure all accessories are off so you don’t cause
an arc.
7. Someone should be within range of your voice, or close enough to come to
your aid when you work near batteries.
8. Have plenty of fresh water, soap and a supply of baking soda on hand in
the area of the batteries in case of contact with battery acid. Baking soda
neutralizes lead acid battery electrolyte.
9. The product is supplied with a rechargeable, sealed lead acid battery. This
battery is self contained and not consumer replaceable. Batteries must be
disposed of properly when they no longer hold a charge. Proper charging
practices will increase the life of the batteries.
