1. Replace stem assembly and retighten retention nut.
Reattach trigger lever.
As needed: Clean the inline strainer (Fig. D) when
solution flow is visibly reduced. To clean the filter, loosen
the strainer assembly nut, and remove the strainer and
strainer washer. Rinse these items in clean water and
reassemble the strainer. It is not usually necessary to
replace the inline filter element. Be sure to include the
nylon washer when reassembling, and take care not to
over-tighten the strainer assembly nut.
To maintain appearance, wipe exterior surfaces with a
damp cloth.
