the line pressure is released before disassembly.
METER REASSEMBLY

O
to each other.
(see fig 2). Check the rotor rotation by turning either of the
rotors. If the rotors are not in mesh correctly or do not
rotate freely remove one of the rotors and replace it
correctly at 90
0 to the other rotor. Re-check the operation of
the rotors.
5) Test the meter by turning the rotors with a finger or by
applying low air pressure (No more than a good breath)
to the inlet port of the meter. This will confirm the meter
is operating correctly.
