Maintaining Tools
Keep your tool in good repair by adopting a regular maintenance pro-
gram. Before use, examine the general 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 im-
mediately 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 necessary 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
Maintaining Hammer Chisels
Through normal use, the shank of the chisel can "mushroom" over and cause
the chisel to become stuck inside the hammer. To prevent this from happen-
ing, periodically remove the chisel from the tool and inspect the shank. If the
shank starts to "mushroom", have the chisel refurbished or replaced.
Brush Replacement
These MILWAUKEE hammers are will automatically shut off when the
brushes need to be replaced. Return your tool to the nearest MILWAUKEE
service facility for repairs.
Service Indicator Light
These MILWAUKEE Hammers feature a service indicator light. When the
red light turns on, the tool is in need of servicing. Return your tool to the
nearest MILWAUKEE service facility for service.
NOTE: When the service light comes on, the tool will continue to run for a
few hours and then the motor will shut off.
MAINTENANCE
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
thinner, paint thinner, chlorinated cleaning solvents, ammonia and house-
hold detergents containing ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the nearest service center.

forming any maintenance. Never disassemble the tool or try to do
any rewiring on the tool's electrical system. Contact a MILWAUKEE
