MAINTENANCE
WARNING!
To reduce the risk of injury, always unplug the charger and remove the battery pack from the charger or tool before performing any maintenance. Never disassemble the tool, battery pack or charger. Contact a MILWAUKEE service facility for ALL repairs.
Keep your tool, battery pack and charger in good repair by adopting a regular main- tenance program. After six months to one year, depending on use, return the tool, battery pack and charger to a MILWAUKEE service facility for:
•Lubrication
•Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.)
•Brush inspection and replacement
•Electrical inspection (battery pack, charger, motor)
•Testing to assure proper mechanical and electrical operation
Maintaining Tool
If the tool does not start or operate at full power with a fully charged battery pack, clean the contacts on the battery pack. If the tool still does not work properly, return the tool, charger and battery pack, to a MILWAUKEE service facility for repairs.
Maintaining Battery Pack
MILWAUKEE battery packs will operate for many years and/or hundreds of cycles when they are maintained and used ac- cording to these instructions.
A battery pack that is stored for six months without being used will discharge itself. Batteries discharge at a rate of about 1% per day. Charge the battery every six months even if it is unused to maximize battery life. Do not tape the trigger in the “ON” position and leave the tool unattended as this may discharge the battery to a point where it will no longer be able to recharge.
Use a MILWAUKEE battery pack only until it no longer performs with the power and torque needed for your application.
Store your battery pack in a cool, dry place. Do not store it where the temperature may exceed 120°F (50°C) such as a vehicle or metal building during the summer. High tem- peratures will overheat the battery pack, reducing battery life. If it is stored for sev- eral months, the battery pack will gradu- ally lose its charge. One to three cycles of charging and discharging through normal use will restore the capacity of the battery pack. During the life of the battery pack the operating time between charges becomes shorter. If the operating time becomes ex- tremely short after a proper charge, the usable life of the battery pack has been reached and it should be replaced.
WARNING!
To reduce the risk of personal injury and damage, never immerse your tool, battery pack or charger in liquid or allow a liquid to flow inside them.
Cleaning
Clean dust and debris from charger and tool vents. Keep tool handles clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean the tool, battery pack and charger since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include gasoline, turpentine, lac- quer thinner, paint thinner, clhlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use flammable or combustible solvents around tools.
