safety device because it controls
the air supply even if the air hose
is ruptured.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil to the airline connection be-
fore operation. Add a few more drops
after each hour of continual use.
2. Attach an air hose to the compres-
sor’s air outlet. Connect the air hose
to the air inlet of the tool. Other com-
ponents, such as a connector and
quick coupler, will make operation
more efficient, but are not required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air flow, and therefore Air Angle
Die Grinder performance, can be
hindered by undersized air supply
components.
3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.
4. Make sure tool’s Trigger Lever (4) is
in the off position; refer to Operation
section for description of controls.
5. Close the in-line safety valve between
the compressor and the tool.
6. Turn on the air compressor according
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
7. Adjust the air compressor’s output
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.
8. Inspect the air connections for leaks.
Repair any leaks found.
9. If the tool will not be used at this
time, turn off and detach the air sup-
ply, safely discharge any residual air
pressure, and release the throttle
and/or turn the switch to its off posi-
tion to prevent accidental operation.
