performed by the manufacturer or authorized service providers.
IMPACT WRENCH SAFETY WARNING
1. Hold the power tool by insulated gripping surfaces, when performing an operation where the
fastener may contact hidden wiring.
Fasteners contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the operator an electric shock.
SAFETY WARNINGS FOR BATTERY PACK
a) Do not dismantle, open or shred cells or battery pack.
b) Do not short-circuit a battery pack. Do not store battery packs haphazardly in a box
or drawer where they may short-circuit each other or be short-circuited by conductive
materials.
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.
c) Do not expose battery pack to heat or fire. Avoid storage in direct sunlight.
d) Do not subject battery pack to mechanical shock.
e) In the event of battery leaking, do not allow the liquid to come into contact with the skin or

(20 °C ± 5 °C).
m) When disposing of battery packs, keep battery packs of different electrochemical systems
separate from each other.
