IMPORTANT SAFETY INSTRUCTIONS - SAVE THESE INSTRUCTIONS
Read all safety warnings, instructions, illustrations and specifications provided with this tool.
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
1. Do not obstruct ventilation openings or mount in
zero clearance compartment. Overheating may
increase the risk of fire and electric shock.
2. Do not expose to rain or use in damp locations.
3. Remove the battery before servicing.
4. Do not use inverter if it has been dropped
or impacted sharply. Use of a damaged
device increases the risk of fire.
5. Remove the battery pack from the
inverter when not in use.
6. Do not disassemble the battery inverter.
7. Keep out of the reach of children.
8. Store power inverter indoors and
out of the reach of children.
9. AC Output must be used for powering
devices of 300W or less. Connecting large
loads to the inverter can lead to damage.
10. Plugs must properly fit the outlet without
being forced. Do not insert any plug into the
inverter if it does not fit easily into place.
11. Power inverter must be kept in cool
environment. Keep away from heat.
12. Do not use power inverter near flammable
gases or fumes. Do not power medical
equipment with this power inverter.
13. Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of
fire when used with another battery pack.
14. Use power inverter only with specifically
designated battery packs. Use of any other battery
packs may create a risk of injury and fire.
15. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
16. Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
17. Do not use a battery pack or power inverter that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
18. Do not expose a battery pack or power tool to
fire or excessive temperature. Exposure to fire or
temperature above 140°F may cause explosion.
19. Follow all charging instructions and do not charge
the battery pack outside of the temperature range
specified in the instructions. Charging improperly or
at temperatures outside of the specified range may
damage the battery and increase the risk of fire.

20. Have servicing performed by a qualified repair person
using only identical replacement parts. This will
ensure that the safety of the product is maintained.
21. Do not modify or attempt to repair the power
inverter or the battery pack except as indicated
in the instructions for use and care.
22. The battery Charger gets hot during use.
The Charger’s heat can build up to unsafe
levels and create a fire hazard if it does
not receive adequate ventilation, due to
an electrical fault, or if it is used in a hot environment.
Do not place the Charger on a flammable surface.
Do not obstruct any vents on the Charger.
Especially avoid placing the Charger on carpets
and rugs; they are not only flammable, but they
also obstruct vents under the Charger. Place the
Charger on a stable, solid, nonflammable surface
(such as a stable metal workbench or concrete floor)
at least 1 foot away from all flammable objects, such
as drapes or walls. Keep a fire extinguisher and a
smoke detector in the area. Frequently monitor the
Charger and Battery Pack while charging.
