allow spring tension to rest against chisel. Make sure
chisel collar is between barrel and retaining part of
spring.

Lubrication
An automatic in-line filter-regulator-lubricator is
recommended as it increases tool life and keeps the
tool in sustained operation. The in-line lubricator
should be regularly checked and filled with air tool oil.
Proper adjustment of the in-line lubricator is performed
by placing a sheet of paper next to the exhaust ports
and holding the throttle open approximately 30
seconds. The lubricator is properly set when a light
stain of oil collects on the paper. Excessive amounts
of oil should be avoided.

In the event that it becomes necessary to store the
tool for an extended period of time (overnight, week-
end, etc.), it should receive a generous amount of
lubrication at that time. The tool should be run for
approximately 30 seconds to ensure oil has been
evenly distributed throughout the tool. The tool should
be stored in a clean and dry environment.
Recommended lubricants: Use air tool oil or any
other high grade turbine oil containing moisture
absorbents, rust inhibitors, metal wetting agents and
an EP (extreme pressure) additive.

WARNING:
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or
reproductive harm. Some examples of these chemicals
are:
·
Lead from lead-based paints
·
Crystalline silica from bricks, cement and other
masonry products
·
Arsenic and chromium from chemically treated
lumber
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated
area and work with approved safety equipment such as
those dust masks that are specially designed to filter out
microscopic particles.
