OPERATION
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
STORING THE TRANSFER PUMP
Store indoors in a dry, locked-up place out of the reach of
children, with the battery pack removed and power supply
disconnected. Keep away from corrosive agents such as
garden chemi cals and de-icing salts.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
After extended use, disconnect the battery pack and flush
the pump from the inlet side with fresh clean water. This pre-
vents any build up of solid deposits on the pump’s internal
water sensors.
MAINTENANCE
REPLACING THE IMPELLER AND O-RING
See Figures 8 - 9.

Remove battery pack or disconnect pump from power
source.

Locate and remove the four screws from the impeller
plate cover.

Carefully remove impeller cover plate and inspect o-ring
for damage or wear. If o-ring is damaged or worn, replace
o-ring.
NOTE: Be sure to keep the pump cover, plastic window,
and glass plate together in the same order for installation.

Remove old impeller and replace with new, lining up the
key, and insert into the pump as far as it will go.

Apply a small amount of silicone grease to the impeller
vanes for best performance.

Make sure o-ring is properly seated and replace impeller
cover plate, plastic window, and glass plate.

Replace the four screws and hand tighten only. Refer
to Starting/Stopping the Transfer Pump and check to
make sure the impeller plate does not leak.
STARTING/STOPPING THE TRANSFER PUMP
See Figures 5 - 7.
WARNING:
Battery tools are always in operating condition, therefore
the unit should always be in the OFF position, with the
battery pack removed, when not in use. Do not leave unit
on while unattended. Failure to follow these instructions
could result in serious personal injury.

Add water or a small amount of silicone based pump oil
to the water inlet side of the pump to prime the impeller.
NOTE: For best results, add water to the inlet to prime
the pump. This step is necessary to improve the priming
reliability.

Insert the battery.

Make sure the inlet hose and filter are attached. See As-
semble Intake Filter and Hose in
Assembly
