Inlet/Outlet Hoses
• Use hoses with 3/4" GHT female fittings.
• A heavy duty hose should be used for the inlet
hose to prevent the hose from collapsing. For best
results, use a short length, large diameter hose,
such as a 6' long, 3/4" inner diameter garden hose.
Longer or thinner hoses may reduce performance
and flow rate.
• A regular garden hose may be used as an outlet
hose.
• Use thread seal tape or a gasket on the inlet to create
an airtight connection ensure the pump will prime.
• Make sure connections are tight.
• Small leaks in the inlet hose will greatly reduce
suction and the efficiency of the pump, and may
prevent priming.
• Thread the inlet and outlet hoses onto the pump.

waterproof or weatherproof and is not intended to be
used outdoors or inside showers, saunas or other
potentially wet locations.
1. Attach inlet and outlet hoses.
2. Place inlet hose below water surface, aiming as
near as possible to the middle of the water source.
3. Lay out inlet and outlet hoses to ensure there are
no blockages, kinks or bends.
4. Secure outlet hose to ensure it does not whip around
or move unexpectedly when pumping begins.
5. Place pump flat on it's feet for maximum stability.
6. Insert battery pack.
7. Turn on pump.

pump could occur. To prevent pump damage, a
dry pump may shut off automatically within 60
seconds. Turn pump off to reset.
11. For best results, the pump should be no more
than 18 feet above the inlet source. The maximum
discharge height is 75 feet.
NOTE: If anything but clear water is accidentally
pumped, flush with clear water for at least 30
seconds.
12. Do not block air vents. If overload occurs, due to
overheating, a jammed impeller, etc, turn off the
pump immediately. Pump may shut off automati-
cally. Clear the jam and allow the tool to cool be-
fore restarting. Turn pump off and back on to reset.
13. Do not run the pump for more than 1 hour continu-
ously.
14. When done, remove inlet and outlet hoses and
pour any excess water from the pump. To remove
remaining water from pump, run pump for no
more than 5 seconds. In cold situations, freezing
temperatures can cause remaining water in the
pump to freeze and damage the pump.
