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 grinding 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. 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.
