MAINTENANCE / SERVICE
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, 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 necessary until the motor brushes need to be
replaced. After six months to one year, depending on use, return your tool to the nearest
service station 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
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.
CHANGE CARBON BRUSHES
Remove and check the carbon brushes regularly. Keep the carbon brushes clean and free to
slip in the holders. Both carbon brushes should be replaced at the same time. Use only
identical carbon brushes. Use a screwdriver to remove the brush holder caps. Take out the
worn carbon brushes, insert the new ones and secure the brush holder caps.
After replacing brushes, plug in the tool and break in brushes by running tool with no load for
about 10 minutes. Then check the tool while running and electric brake operation when
releasing the switch trigger.
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
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.
