Step 2. Lift the strainer element (conical screen) out of
the strainer body.
Step 3. Carefully scrub down the strainer element with
a rigid nylon brush until all matter is loosened.
Do not use a steel brush.

Step 5. Wash all matter from the strainer gaskets and
clean the inner-ring where the bottom of the
strainer element rests.

the strainer element into the body of the strainer.
Step 7. Make sure the strainer head gasket is secure on
the top of the strainer body. On V-band models,
O-rings should be seated completely in the body

* For clamped models, opening and closing is achieved
without adjusting the lock nut. It is tightened at the
factory to the correct compression. (Minor tightening
may be necessary if the gasket loses memory over time.)
To open the clamp, depress the safety latch and pull
the over-center lever outward. To close the clamp,
make sure the T-bolt is seated in its receiver and push
the over-center lever back toward the strainer housing.
Be sure that the safety latch is engaged before putting
the unit to use.
