For your safety and the safety of others, read and understand
the safety recommendations and operating instructions before
operating an Airetrol.
Safety Recommendations
Hearing protectors are required in high noise areas, 85 dBA or
greater. The operation of other tools and equipment in the area,
reflective surfaces, process noises and resonant structures can
substantially contribute to, and increase the noise level in an
area. For additional information on hearing protection, refer to
Federal OSHA Regulations, 29 Code of Federal Regulations,
Section 1910.95, Occupational Noise Exposure, and American
National Standards Institute, ANSI S12.6 Hearing Protectors.
Airetool Airetrols are designed to operate on 90 psig (6.2 bar)
maximum air pressure. If the tool is properly sized and applied,
higher air pressure is unnecessary. Excessive air pressure in-
creases the load and stresses on the tool parts, which may
result in cage, mandrel or roll breakage. Installation of a filter-
regulator-lubricator in the air supply line ahead of the tool is rec-
ommended.
Before the tool is connected to the air supply, check the throttle
for proper operation (i.e., throttle moves freely and returns to the
closed position). Clear the air hose of accumulated dust and
moisture. Be careful not to endanger adjacent personnel. Be-
fore removing a tool from service or changing sockets, make
sure the air line is shut off and drained of air. This will prevent
the tool from operating if the throttle is accidently engaged.
It is essential for the safe operation that the operator of an Airet-
rol use good balance, sure footing, and proper posture in antici-
pation of the torque reaction. Insure that the operator’s hand will
not be wedged or pinched between the work and the tool when
operating.
Tools with clutches can stall rather than shut-off if adjusted
over the maximum power output of the tool, or if there is a drop
in air pressure. Operator must then resist the stall torque until
the throttle is released.
Higher torque right angle Airetrols can be equipped with spline
torque reaction mounting plates which accept torque reaction
bars. These bars can be braced against the work or other suit-
able points to absorb and relieve the operator of the torque reac-
tion transmitted by the tool. Tool balance arms are also avail-
able to absorb the torque reaction of the tool while balancing the
weight of the tool for improved ergonomic applications.
Some individuals are susceptible to disorders of the hands and
arms when exposed to tasks which involve highly repetitive mo-
tions and/or vibration. Those individuals predisposed to
vasculatory or circulatory problems may be particularly suscep-
tible. Cumulative trauma disorders such as carpal tunnel syn-
When using right angle Airetrols, be sure the throttle is posi-
tioned relative to the angle head so that the throttle will not be-
come wedged against an adjacent object in the “ON” position
due to torque reaction. The angle head may be repositioned with
respect to the lever to accomodate proper location for the task. If
tool is to be reversed, locate throttle lever in a neutral position
that will prevent entrapment. Refer to operating instructions for
additional information.
For additional information on eye and face protection, refer to
Federal OSHA Regulations, 29 Code of Federal Regulations,
Section 1910.133., Eye and Face Protection, and the American
National Standards Institute, ANSI A87.1, Occupational and
Educational Eye and Face Protection. Z87.1 is available from

drome and tendonitis can be caused or aggravated by repeti-
tious, forceful exertions of the hands and arms. These disorders
develop gradually over periods of weeks, months and years.
