Drilling in Wood, Composition Materials and
Plastic
When drilling in wood, composition materials and
plastic, select the drill operating mode. Start the drill
slowly, gradually increasing speed as you drill. Se-
lect low speeds for plastics with a low melting point.
Drilling in Metal
When drilling in metal, select the drill operating
mode. Use high speed steel twist drills or hole
saws. Use a center punch to start the hole. Lubri-
cate drill bits with cutting 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.
Drilling in Masonry
When drilling in masonry, select the rotary hammer
operating mode. Use high speed carbide-tipped
bits. Drilling soft masonry materials such as cinder
block requires little pressure. Hard materials 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. Do not
attempt to drill through steel reinforcing rods. Both
actions will damage the carbide.

injury, always unplug your tool before
performing any maintenance. Never disas-
semble the tool or try to do any rewiring
on the tool's electrical system. Contact a
mIlwAukEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the gen-
eral condition of your tool. Inspect guards, switches,
tool cord set and extension cord for damage. Check
for loose screws, misalignment, binding of moving
parts, improper mounting, broken parts and any
other condition that may affect its safe operation. If
abnormal noise or vibration occurs, turn the tool off
immediately and have the problem corrected before
further use. Do not use a damaged tool. Tag damaged
tools "DO NOT USE" until repaired (see "Repairs").
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electrical
operation

electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to flow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your tool
since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include: gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use flammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
