Using the Power Port

After installing the battery pack, open the access 
door and plug in a 12 V Automotive or 5 V USB 
powered appliance.

If the appliance draws more than the rated output of 
the outlet, the power port will shut off to protect the 
battery pack. To restart the power port, remove and 
reinstall the battery pack. Use only appliances rated 
within the output specifi cations for the port. 

OPERATION

WARNING 

Always remove battery 

pack before changing or removing acces-
sories. Only use accessories specifically 
recommended for this tool. Others may be 
hazardous.

MAINTENANCE

WARNING 

To reduce the risk of per-

sonal injury and damage, never immerse your 
tool, battery pack or charger in liquid or allow 
a liquid to fl ow inside them.

WARNING 

To reduce the risk of injury, 

always unplug the charger and remove the 
battery pack from the charger or power port 
before performing any maintenance. Never 
disassemble the power port, battery pack or 
charger. Contact a MILWAUKEE
 service facil-
ity for ALL repairs.

Maintaining Tool 

Keep your power port, battery pack and charger 
in good repair by adopting a regular maintenance 
program. After six months to one year, depending 
on use, return the power port, battery pack and 
charger to 

a MILWAUKEE

 service facility for:

• Electrical inspection

• Testing to assure proper mechanical and

electrical operation

If the power port does not start or operate at full 
power with a fully charged battery pack, clean the 
contacts on the battery pack. If the power port still 
does not work properly, return the power port, 
charger and battery pack, to a 

MILWAUKEE

 service 

facility for repairs.

Cleaning

Clean dust and debris from charger and power 
port. Keep power port clean, dry and free of oil 
or grease. Use only mild soap and a damp cloth 
to clean the power port, battery pack and charger 
since certain cleaning agents and solvents are 
harmful to plastics and other insulated parts. Some 
of these include gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents, 
ammonia and household detergents containing 
ammonia. Never use fl ammable or combustible 
solvents around power port.
