Maintenance - Milwaukee 0612-20 Operator's Manual

APPLICATIONS
WARNING
To reduce the risk of electric shock,
check work area for hidden pipes
and wires before drilling or driving
screws.
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, start the drill slowly, gradually
increasing speed as you drill. When drilling
into wood, use wood augers or twist drill bits.
Always use sharp bits. When using twist drill
bits, pull the bit out of the hole frequently to
clear chips from the bit fl utes. To reduce the
chance of splintering, back work with a piece
of scrap wood. Select low speeds for plastics
with a low melting point.
Drilling in Metal
When drilling in metal, use high speed steel
twist drills or hole saws. Use a center punch
to start the hole. Lubricate drill bits with cut-
ting oil when drilling in iron or steel. Use a
coolant when drilling in nonferrous metals
such as copper, brass or aluminum. Back
the material to prevent binding and distortion
on breakthrough.
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 fi rm pressure before pulling the trig-
ger. Screws can be removed by reversing
the motor.
Overloading
Continuous overloading may cause perma-
nent damage to tool or battery pack.
WARNING
High rotational force. To reduce the
risk of injury, always hold or brace
securely.
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 specifi c
purposes.
• Use caution when drilling pitchy, knotty,
wet or warped material or when drilling in
material that may contain nails, screws,
staples, etc.

MAINTENANCE

WARNING
To reduce the risk of injury,
always unplug the charger and
remove the battery pack from
t h e c h a r g e r o r t o o l b e f o r e
performing any maintenance.
N e v e r d i s a s s e m b l e t h e t o o l ,
battery pack or charger. Contact a
MILWAUKEE service facility for ALL
repairs.
Keep your tool, battery pack and char-
ger in good repair by adopting a regular
maintenance program. After six months
to one year, depending on use, return the
tool, battery pack and charger to a
MILWAUKEE service facility for:
• Lubrication
• Mechanical inspection and cleaning
(gears, spindles, bearings, housing,
etc.)
• Electrical inspection (battery pack,
charger, motor)
• Testing to assure proper mechanical and
electrical operation
Maintaining Tool
If the tool does not start or operate at full pow-
er 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.
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 fl ow 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 include gaso-
line, turpentine, lacquer thinner, paint thinner,
chlorinated cleaning solvents, ammonia and
household detergents containing ammonia.
Never use fl ammable or combustible sol-
vents around tools.
Repairs
For repairs, return the tool, battery pack and
charger to the nearest service center listed on
the back cover of this operator's manual.
