MAINTENANCE

WARNING

To reduce the risk of injury, always unplug your tool before per- forming any maintenance. Never disassemble 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 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.

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 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 thinner, paint thinner, chlorinated cleaning solvents, ammonia and house- hold 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.

ACCESSORIES

WARNING

To reduce the risk of injury, always unplug the tool before attach- ing or removing accessories. Use only specifically recommended accessories. Others may be hazardous.

For a complete listing of accessories refer to your MILWAUKEE Elec- tric Tool catalog or go on-line to www.milwaukeetool.com. To obtain a catalog, contact your local distributor or a service center.
