Interior pump cleaning
Keeping the pump clean will allow it to perform its best and prolong the life of the
pump. Never pump water from a standing source without using a lter / screen. Do
not store the pump without draining the pump housing. Do not allow dirt or debris to
dry inside the pump housing. You can clean the interior of the pump by following the
steps below:
1. Disconnect the spark plug lead from the engine. Place it to the side of the plug.
2. Drain the system as outlined in DRAINING THE SYSTEM FOR STORAGE section
of this manual.
3. Using a screw or nut driver, loosen the worm screw clamps (Fig. 22). Carefully
remove them from the anges then slide them to the right.
4. Using an open end wrench, loosen and remove the six nuts (four under the engine,
two under the pump) that hold the unit to the vibration mounts (Fig. 23).
NOTICE

and internal components. Damage caused by chemical cleaners and corrosive liquids
is not covered under warranty. To avoid damaging pump seals and components, do not
use chemical cleaners or corrosive liquids to clean the components inside the pump
housing.
