Operation
After change of reservoir or after malfunction, for
example if pump sucked air:
⇒ See instructions in section 5.
2 ‘Initial Operation’.
The required air pressure to pump can be set again
thus continuing standard operation after change of the
material reservoir, when pump priming is completed.
Putting out of operation
If using pumping materials that may alter when
equipment is shut-down and pump is not used for
longer periods of time, flush the pump (pump tube). In
some cases it may become necessary to disassemble
and clean the pump tube before storage.
CAUTION
Flush pump again with mineral oil before phase out /
storage if a cleaning material is used that can cause
corrosion after flushing.
5.
4 Inspection and maintenance
Inspection and maintenance works shall be carried out
by skilled, qualified personnel only.
Warning.
Hands away from lower part of the
pump (material inlet) and all outlets for
the material.
Never attempt to disassemble pump /
equipment while system (pump and
system components) is pressurized.
− If using a FRL-Air service unit:
Periodically as well as in time, open drain cock of air
filter and blow-down bowl from moisture and dirt.
Periodically as well as in time, refill reservoir of air
lubricator.
If an air line lubricator is not used, perform manual
lubrication at least 1 x per day prior to operation of
pump. Before coupling the air quick-coupling to air
motor inject some drops of light mineral oil into the air
coupler nipple using an oiler/oil can.
− Check screwed connections and hoses of material
supply system regularly for fastening and leaks.
Replace damaged hoses immediately.
− Keep pump neat and clean. Keep stickers legible.
Visually check pump for proper shape and
completeness before operation.
− Lubricate air valve mechanism of airmotor at least
1 x per year.
⇒ See illustration and instructions in section 6. ‘Repair’.
5.
5 Preventative maintenance
Preventative maintenance by replacing wear parts
(for example seals and valves) in time is recommended.
Service life of parts depends on the material pumped
and working strains of the equipment.
• It is recommended to disassemble the air valve
mechanism of the pump drive 1 x per year. Replace
parts found worn.
− Lubricate air valve mechanism on assembly.
⇒ See illustration and instructions in section 6. ‘Repair’.
Preventative maintenance works and repairs shall be
carried out by qualified, trained personnel only.
If the user should not have personnel to perform such
works, please contact
Lincoln GmbH & Co. KG, Service department.
⇒ Address / telephone see foot line.
5.
6 Trouble shooting
Repair works must be performed by qualified, trained
personnel only if any repair required.
Warning
• Never attempt to disassemble pump while airmotor,
pump tube and fluid system are pressurized.
• Hands away from lower part of the pump (material
inlet) when pump is in operation mode.
• Do not exceed the max. working of pump/equipment
when performing adjustments/settings that cause
changes of the operating pressure.
If working problems can only be eliminated by repair of
the pump:
− Shut off pump immediately for repair.
If overpressurizing of the pump/equipment is believed to
have occurred, return pump for inspection and repair.
Contact Lincoln GmbH & Co. KG.
⇒ Address / telephone see foot line.
CAUTION
If pump accelerates to abnormal high frequency of
pump cycles, for example when pump is cavitating,
immediately shut off pump.
