Ensure Proper Pressure, Filtration & Lubrication
Properly lubricated pneumatic tools work better, last longer between maintenance
intervals and are safer in general use. The maintenance costs are reduced dramatically
when a little time is taken to regularly lubricate the tools. There are several ways to
ensure proper lubrication.
1) Filters, Regulators & Lubricators
These devices should be installed in the air system at each work station and inspected
regularly to ensure proper operation. Each device in this set performs a vital task that
greatly affects the performance of the tool and overall longevity of the component
parts.
Filters
A filter is a device used to trap/contain particulate and liquid contaminants in the
compressed air system. They generally have a cartridge or screen that requires
cleaning or replacement regularly. Without this maintenance, the filtering device can
become clogged and reduce the flow of air to the tool. A loss in performance can result.
Regulators
A regulator adjusts the operating pressure supplied to the tool. This device generally is
used with a pressure gauge that will indicate the current pressure setting. All Top Cat
® pneumatic tools are designed to operate at 90 PSI (6.2 bar) while the tool is running.
The tool should never be run if the pressure should exceed 90 PSI (6.2 bar).
Lubricators
Lubricators are devices that induce a controlled amount of oil into the air supply for
pneumatically driven tools. They generally contain a reservoir that one must keep filled
with oil. A light grade oil such as Mobil DTE light or equivalent is recommended. There
is a variable setting on the lubricator that will determine the amount of oil induced into
the air supply. Lubricators should be adjusted to add one to two drops of oil per minute.
It is important to inspect both the setting and amount of oil in the lubricator regularly to
determine proper functioning of the device. The lack of oil in the air system will greatly
reduce the performance and longevity of the pneumatically driven tool.
2) Direct injection of oil into the tool
A simple and easy way to ensure proper lubrication is to inject the oil directly into the
tool air inlet. This should be performed prior to storage of the tool. To perform this task
one must have a small container of the proper lubricating oil.
● Disconnect the tool from the air supply at the air coupling.
● Place a few drops of oil from the container into the air inlet of the tool directly.
● Reconnect the tool to the air supply.
