Action
Turn off the hand operated air valve and make sure
that the air filter is not pressurized.
Remove the bowl assembly, by following these
steps:
• Push the bowl assembly lock button.
• Lift the bowl assembly.
• Rotate the bowl assembly 45° (right or left).
• Pull out the assembly.
Remove the baffle, filter element and deflector by
rotating the baffle counterclockwise by hand.
Fit the deflector to the body assembly. Mind the fit-
ting direction of the deflector (concave in which the
element goes into).
Fit the new filter element by inserting it to the de-
flector concave.
Fit the baffle by inserting it to the filter element.
Mind the fitting direction of the baffle (convex to
which the element goes).
Tighten the baffle to settle the baffle, filter element
and deflector by rotating the baffle counterclockwise
until it contacts the element and deflector lightly.
Rotate approximately one half revolution counter-
clockwise further in order to tighten them.
Fit the bowl assembly.
Match the mating mark of the body and the bowl
assembly to insert the assembly to the body. Rotate
the assembly 45° (right or left) until the lock button
is tossed up to fit the bowl assembly.
