SMA794C REPLACING FUELFILTER

1. Disconnect watersensor connector andreplace fuelfilter
with anew one.

Hand-tighten fuelfilter byabout 2/3turn after O-ring touches
mounting surface.Followtheinstructions onfuel filter.

2. Connect watersensor connector andbleed fuelsystem.

FUEL SYSTEM AIRBLEEDING

1. Move priming pumpupand down until
there issuddenly
more resistance inthe movement. Thenstopthisaction and
start theengine.

2. Ifengine doesnotoperate smoothly afterbeing started,
race ittwo orthree times.

When refilling empty-fueltank, bleed airout offuel system.
