This pump is pressurized
internally with air pressure
during operation. Always
make certain that all bolting
is in good condition and
that all of the correct
bolting is reinstalled during assembly.
Before pump operation,
i n s p e c t a l l g a s k e t e d
fasteners for looseness
caused by gasket creep. Re-
torque loose fasteners to
prevent leakage. Follow recommended torques
stated in this manual.
When used for toxic or
aggressive uids, the pump
should always be ushed
clean prior to disassembly.
Before maintenance or
repair, shut off the com-
pressed air line, bleed the
pressure, and disconnect
the air line from the pump.
The discharge line may be
pressurized and must be bled of its pressure.
Before doing any main-
ten ance o n the pum p,
be certain all pressure is
completely vented from the
pump, suction, discharge,
p i p i n g , a n d all o t h e r
openings and connections. Be certain the air
supply is locked out or made non-operational,
so that it cannot be started while work is being
done on the pump. Be certain that approved
eye protection and protective clothing are worn
all times in the vicinity of the pump. Failure to
follow these recommendations may result in
serious injury or death.
Airborne particles and
loud noise hazards.
Wear ear and eye
protection.
In the event of diaphragm
rupture, pumped material
may enter the air end of the
pump, and be discharged
into the atmosphere. If
pumping a product which is hazardous or toxic,
the air exhaust must be piped to an appropriate
area for safe disposition.
Take action to prevent static
sparking. Fire or explosion
can result, especially when
handling ammable liquids.
The pump, piping, valves,
containers or other miscellaneous equipment
must be grounded. (See page 32)
Read these safety warnings
and instructions in this
manual completely, before
installation and start-up
of the pump. It is the responsibility of the
purchaser to retain this manual for reference.
Failure to comply with the recommendations
stated in this manual will damage the pump,
and void factory warranty.

Many components of LINCOLN Air-Operated
Diaphragm pumps are made of recyclable
materials (see chart on page 9 for material
specications). We encourage pump users to
recycle worn out parts and pumps whenever
possible, after any hazardous pumped uids
are thoroughly ushed.
Systems which will be dispensing uids under
pressure may need to be protected by using
a thermal relief kit which will safely limit the
pressures caused by thermal expansion. Please
contact your local Lincoln distributor and
refer to Service Page Section K5 Page 31 for
more details. Failure to include thermal relief
protection may cause damage not covered
under Lincoln’s warranty policy.
