Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
operation. Return the tool, battery pack, and charger
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool, battery pack and charger to a MILWAUKEE
service facility for inspection.
If the tool does not start or operate at full power with
a fully charged battery pack, clean the contacts on
the battery pack. If the tool still does not work prop
-
erly, return the tool, charger and battery pack, to a
MILWAUKEE service facility for repairs.

ONE-KEY™
WARNING
Chemical Burn Hazard.
This device contains a
lithium button/coin cell battery. A new

-
ternal burns and lead to death in as
little as 2 hours if swallowed or enters the body.
Always secure the battery cover. If it does not
close securely, stop using the device, remove the
batteries, and keep it away from children. If you
think batteries may have been swallowed or en
-
tered the body, seek immediate medical attention
.

1. Remove the battery pack.
2. Remove the screw and open the battery door.
3. Remove the old battery, keep it away from children,
and dispose of it properly.

Cleaning
Clean dust and debris from vents. Keep trigger

include gasoline, turpentine, lacquer thinner, paint
thinner, chlorinated cleaning solvents, ammonia and
household detergents containing ammonia. Never
use flammable or combustible solvents around tools.
