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. Output non-sinusoidal.
2. Do not obstruct ventilation openings or mount in
zero clearance compartment. Overheating may
increase the risk of fire and electric shock.
3. Do not expose to rain or use in damp locations.
4. Remove the battery before servicing.
5. Neutral floating.
6. For use with Bauer 20V Li-Ion battery
packs (sold separately).
7. Do not use inverter if it has been dropped
or impacted sharply. Use of a damaged
device increases the risk of fire.
8. Remove the battery pack from the
inverter when not in use.
9. Do not disassemble the battery inverter.
10. Keep out of the reach of children.
11. Store power inverter indoors and
out of the reach of children.
12. AC Output must be used for powering
devices of 150W or less. Connecting large
loads to the inverter can lead to damage.
13. 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.
14. Power inverter must be kept in cool
environment. Keep away from heat.
15. Do not use power inverter near flammable
gases or fumes. Do not power medical
equipment with this power inverter.
16. 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.
17. Use inverter only with specifically designated
battery packs. Use of any other battery
packs may create a risk of injury and fire.
18. 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.
19. 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.
20. Do not use a battery pack or inverter that is
damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.

21. Do not expose a battery pack or power inverter to
fire or excessive temperature. Exposure to fire or
temperature above 140°F may cause explosion.
22. 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.
23. Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that the
safety of the product is maintained.
24. Do not modify or attempt to repair the inverter
or the battery pack except as indicated
in the instructions for use and care.
25. 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.
