USING QUICK CHANGE RETAINER
1 Disconnect air supply and remove all accesso
ries.
Thread quick change chisel retainer onto end of
barrel.
While pushing end of spring to side of the toot,
insert a standard .401" taper shank chisel into
barrel and allow spring tension to rest against
chisel. Make sure chisel is between barrel and
retaining part of spring.
Remove chisel by pushing spring to si(
and pull chisel out of barrel.

Always hold chisel to work surface before
operating tool.
Lubrication
An in-line filter-regulator-lubricator (fig 1) is recommended
as it increases toot life and keeps the toot in sustained
operation. The in-line lubricator should be regularly
checked and filled with air toot 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 3). The tool should be run for
approximately 30 seconds to ensure oil has been evenly
distributed throughout the toot. 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. 3 for location/air inlet).
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.
