Maintenance - Milwaukee 0613-20 Operator's Manual

Drilling in Masonry
When drilling in masonry, select the
hammer-drill operating mode
(Cat. No. 0613-20, 0614-20, and 0624-20
only). Use high speed carbide-tipped bits.
Drilling soft masonry materials such as cin-
der block requires little pressure. Hard ma-
terials like concrete require more pressure.
A smooth, even flow of dust indicates the
proper drilling rate. Do not let the bit spin in
the hole without cutting. Do not use water
to settle dust or to cool bit. Both actions
will damage the carbide.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into
thick or hard materials. Set the torque se-
lector collar to the proper position and set
the speed to low. Use the proper style and
size screwdriver bit for the type of screw
you are using.
With the screwdriver bit in the screw, place
the tip of the screw on the workpiece and
apply firm pressure before pulling the trig-
ger. Screws can be removed by reversing
the motor.
Overloading
Continuous overloading may cause per-
manent damage to tool or battery pack.
WARNING!
High rotational force. To reduce
the risk of injury, always hold or
brace securely. Always use side
handle on tools.
Bit Binding
A high rotational force occurs when a bit
binds. If the bit binds, the tool will be forced
in the opposite direction of the bit rotation.
Bits may bind if they are misaligned or when
they are breaking through a hole. Wood
boring bits can also bind if they run into
nails or knots. Be prepared for bit binding
situations.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely
to bind when drilling.
• Use the proper bit for the job. There are
bits that are designed for specific pur-
poses.
• Use caution when drilling pitchy, knotty,
wet or warped material or when drilling
in material that may contain nails.

MAINTENANCE

WARNING!
To reduce the risk of personal
injury, always unplug the
charger and remove the battery
pack from the charger or tool
before performing any
maintenance. Never disassemble
the tool, battery pack or charger.
Contact a MILWAUKEE service
facility for ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger
in good repair by adopting a regular main-
tenance program. After six months to one
year, depending on use, return the tool,
battery pack and charger to a MILWAUKEE
service facility for:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning
(gears, spindles, bearings, housing,
etc.)
• Electrical inspection (battery pack,
charger, motor)
• Testing to assure proper mechanical
and electrical operation
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 properly, return
the tool, charger and battery pack to a
MILWAUKEE service facility for repairs.
Maintaining Battery Pack
MILWAUKEE battery packs will operate
for many years and/or hundreds of cycles
when they are maintained and used ac-
cording to these instructions.
A battery pack that is stored for six months
without being used will discharge itself.
Batteries discharge at a rate of about 1%
per day. Charge the battery every six
months even if it is unused to maximize
battery life. Do not tape the trigger in the
"ON" position and leave the tool unattended
as this may discharge the battery to a point
where it will no longer be able to recharge.
Use a MILWAUKEE battery pack only until
it no longer performs with the power and
torque needed for your application.
Store your battery pack in a cool, dry place.
Do not store it where the temperature may
exceed 120°F (50°C) such as in a vehicle
or metal building during the summer. High
temperatures will overheat the battery pack,
reducing battery life. If it is stored for sev-
eral months, the battery pack will gradu-
ally lose its charge. One to three cycles of
charging and discharging through normal
use will restore the capacity of the battery
pack. During the life of the battery pack,
the operating time between charges be-
comes shorter. If the operating time be-
comes extremely short after a proper
charge, the usable life of the battery pack
has been reached and it should be re-
placed.
WARNING!
To reduce the risk of personal
injury and damage, never
immerse your tool, battery pack
or charger in liquid or allow a
liquid to flow inside them.
Cleaning
Clean dust and debris from charger and
tool vents. Keep tool handles clean, dry and
free of oil or grease. Use only mild soap and
a damp cloth to clean the tool, battery pack
and charger since certain cleaning agents
and solvents are harmful to plastics and
other insulated parts. Some of these in-
clude gasoline, turpentine, lacquer thinner,
paint thinner, chlorinated cleaning solvents,
ammonia and household detergents con-
taining ammonia. Never use flammable or
combustible solvents around tools.
