Maintenance
Before Each Use
Before each use, check and torque all fasteners before
operating the equipment. See Torque Sequence , page
29 . Replace worn or damaged parts as needed.
NOTE: Be sure to use a compatible liquid thread sealant
on all replaced male threads.
Check and tighten all air and fluid connections before
operating the equipment. Replace worn or damaged
parts as needed.
Lubrication
The equipment is lubricated at the factory. It is
designed to require no further lubrication for the life of
the equipment. There is no need to add an inline
lubricator under normal operating conditions.
The air valve is designed to operate unlubricated. If
lubrication is desired, every 500 hours of operation (or
monthly) remove the line from the equipment air inlet
and add two drops of machine oil to the air inlet.
Flushing and Storage
•
Flush before changing fluid materials, before fluid
can dry or freeze in the equipment, at the end of the
day, before storing, and before repairing equipment.
• Flush at the lowest pressure possible. Check and
tighten all fasteners and fluid connections. Replace
worn or damaged parts as needed.
• Flush with a solvent that is compatible with the fluid
being dispensed and the equipment wetted parts.
• Flushing schedule will vary based on particular
uses.
• Always cycle the equipment during the entire
flushing process.
• Always perform the Pressure Relief Procedure ,
page 12 , and flush the equipment before storing it
for any length of time.
1. Perform the Pressure Relief Procedure , page 12 .
2. Insert the suction end of the supply line (G) into a
compatible solvent.
3. Open the air regulator (C) to supply low pressure air
to the equipment.
4. Run the equipment for enough time to thoroughly
clean the equipment and lines.
5. Close the air regulator (C).
6. Remove the suction end of the supply line (G) from
the compatible solvent and drain the equipment.
Recycling and Disposal
End of Product Life
At the end of the product’s useful life, dismantle and
recycle it in a responsible manner.
• Perform the Pressure Relief Procedure , page 12.
• Drain and dispose of fluids according to applicable
regulations. Refer to the material manufacturer’s
Safety Data Sheet.
• Deliver remaining product to a recycling facility.
NOTICE
Firmly tighten all fasteners and connections to avoid
air or fluid leaks. To avoid equipment damage, do
not over-torque the fasteners on the equipment. See
Torque Sequence , page 29 .
NOTICE
Do not over-lubricate the equipment. Lubricant is
exhausted through the muffler and could
contaminate your fluid supply or other equipment.
Excessive lubrication can also cause the equipment
to malfunction.
To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
