L ubrication
An inqine filter-regulatorqubricator
(fig 1)
is recommended
as it increases tool life
and keeps the tool in sustained operation.
The inqine lubricator should be regularly
checked and filled with air tool oil. Proper
adjusl;nent
of the inqine lubricator is
performed by placing a sheetofpaper
nextto the tools exhaust ports and holding
the throttle open approximately
32)
seconds. The lubricator is properly set
when a lightstain
ofoil collects on the
paper.
Excessive amounts ofoil should be
avoided. In the eventthat
it becomes
necessary to store the tool foran
extended period of time (overnighL
weekend, etc.), itshould
receive a
generous amount of lubricalJon through
the air inlet(Figure
3). The tool should be
run for approximately
3:Dseconds to
ensure oil has been evenly distributed
throughoutthe
tool. The tool should be
stored in a clean and dry environmenL
R ecommended
L ubricants
Use air tool oil or any other high grade
turbine oil containing
moisture absorbenL
rustinhibitors,
metal wetting agents and
an EP (extreme pressure) additive. See
F igure 3 for Iocation/_tir inleL
