Recommended Air Line Components
Incorporate a lter, regulator with 1.
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best
service, as shown in the diagram
above. An in-line shutoff ball
valve is an important safety device
because it controls the air supply
even if the air hose is ruptured.
The shutoff valve should be a ball
valve because it can be closed
quickly.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil to the airline connection
before operation. Add a few more
drops after each hour of continual
use.
Note: Air ow, and therefore tool
performance, can be hindered by
undersized air supply components.
The air hose must be long enough 3.
to reach the work area with enough
extra length to allow free movement
while working.
Turn the tool’s throttle or switch to the 4.
off position; refer to Operation section
for description of controls.
Close the in-line safety valve between 5.
the compressor and the tool.
Turn on the air compressor according 6.
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
Adjust the air compressor’s output 7.
regulator so that the air output is
enough to properly power the tool,
but the output will not exceed the
tool’s maximum air pressure at any
time. Adjust the pressure gradually,
while checking the air output gauge
to set the right pressure range.
Attach an air hose to the 2.
compressor’s air outlet. Connect the
air hose to the air inlet of the tool.
Other components, such as a coupler
plug and quick coupler, will make
operation more efcient, but are not
required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
Inspect the air connections for leaks. 8.
Repair any leaks found.
If the tool will not be used at this 9.
time, turn off and detach the air
supply, safely discharge any
residual air pressure, and release
the throttle and/or turn the switch to
its off position to prevent accidental
operation.
