MAINTENANCE
WARNING
To reduce the risk of injury, always
remove battery pack before at

Never disassemble the pump, battery pack or
charger. Contact a MILWAUKEE service facility
for ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
operation. Return the tool, battery pack, and charger
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool, battery pack and charger to a MILWAUKEE
service facility for inspection.
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 prop
-
erly, return the tool, charger and battery pack, to a
MILWAUKEE service facility for repairs.
Impeller Replacement/Clearing
Check the impeller for wear before each use. Clear
or replace impeller if blocked or damaged.
1. Remove the four cover screws holding motor hous
-
ing and pump housing together. Cover is now free
and can be removed.
2. Inspect gasket and impeller for wear and damage.
If there is any evidence of wear or damage, replace
the parts (Cat. No. 49-16-2771).
3. Clear any debris from the gasket and impeller.
4. Reassemble gasket, cover, and cover screws.
5. Hand tighten cover screws. Do not use power tools
or over tighten.
6. After extended use or when replacing the impel
-
ler, apply a small amount of silicone grease to the
impeller blades for best performance.
Storage
Never store with liquid inside the pump. To store
the tool:
1. Remove inlet and outlet hoses.
2. Pour excess water from pump.
3. Run pump for no more than 5 seconds.
4. Remove battery pack.
WARNING
To reduce the risk of personal in-
jury 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 vents. Keep handles
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain clean-
ing 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, acetone, and household
detergents containing ammonia. Never use flam
-
mable or combustible solvents around tools.
