5. Turn the Control Ring (3) slowly to
the “ON” position to begin grinding or
cutting. The more you turn the knob,
the higher the RPM.
6. If the tool requires more force to
accomplish the task, verify that the
tool receives sufficient, unobstructed
airflow (CFM) and increase the pres-
sure (PSI) output of the regulator up
to the maximum air pressure rating of
this tool.
CAUTION! TO PREVENT TOOL
AND ACCESSORY FAILURE, RE-
SULTING IN INJURY:
Do not exceed the tool’s maximum
air pressure rating.
If the tool still does not have sufficient
force at maximum air pressure and
sufficient airflow, then a larger tool
may be required.
7. To prevent accidents, turn off the
tool, detach the air supply, safely
discharge any residual air pressure
in the tool. Clean external surfaces
of the tool with clean, dry cloth, and
apply a thin coat of tool oil. Then
store the tool indoors out of children’s
reach.
