MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. 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, bro-
ken 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 electri-
cal operation
WARNING To reduce the risk of injury,
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to fl ow 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

ner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
