of the
tie
rods).
2. Mount

(Item
2) to airmotor

rod.
3. Hand tighten
tie rods to the
pumptube
with four nuts supplied
with airmotor.
4. Slowly
cycle the pump several
times,
using
just
enough
air
pressure
to
operate
the pump without
stalling.
5. Stop the pump on an "up" stroke
and
tighten the four nuts to securely fasten
the airmotor
to the pumptube.

containers
must
be grounded
when
handling

etc.
and
wherever

is hazard.
Check continuity
(a good static wire
connection)
with an ohmmeter.
Place
one probe
on one hose fitting
and
the other probe on other hose fitting,
continuity
or
proper
grounding
through
hose is good when a reading
is obtained
on the ohmmeter.
PREVENT
FIRES.
When
pumping,
flushing
or
recirculating
volatile
