Place chisel against work surface and pull trigger in
short bursts until chisel sets in work. Use both hands to
hold hammer for better control.
Lubrication
An in-line tilter-regulator-lubricator
(fig 1) 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 tools 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, weekend,
etc.), it should receive a generous amount of
lubrication through the air inlet (fig 2). 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
absorbent, rust inhibitors, metal wetting agents and an
EP (extreme pressure) additive. (See Fig. 2 for
location/air inlet).
I, A CAUTION]
Never
operate
hammer
without
a chisel installed
and
placed against
the work surface.
Doing so may result in
personal
injury
or damage
to the tool.
Sears offers a variety of chisels for this hammer.
