CAUTION !
Personal hearing protection is
recommended when operating
or working near this tool.
For your safety and the safety of others, read and under-
stand the safety recommendations and operating instruc-
tions before operating a nutrunner.
Always wear protective equipment:
For additional information on eye protection and face
protection, refer to Federal OSHA Regulations, 29 Code
of Federal Regulations, Section 1910.133., Eye and Face
Protection, and American National Standards Institute,
ANSI Z87.1, Occupational and Educational Eye and Face
Protection. Z87.1 is available from the American National
Standards Institute, Inc., 11 West 42nd Street, New York,
NY 10036.
Hearing protection is recommended 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 the area. Excessive air
pressure above 90 PSIG and worn motor components can
also increase sound level emitted by tool. Proper hearing
conservation measures, including annual audiograms
and training in the use and fit of hearing protection devices
may be necessary. For additional information on hearing
protection, refer to Federal Regulations, Section 1910.95,
Occupational Noise Exposure, and American National
Standards Institute, ANSI S12.6, Hearing Protectors.
Cleco nutrunners 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 increases the loads and stresses on the tool
parts, sockets, and fasteners and may result in breakage.
Installation of a filter-regulator-lubricator in the air supply
line ahead of the tool is recommended.
Before the tool is connected to the air supply, check the
throttle for proper operation (i. e., throttle moves freely and
returns to closed position). Being careful not to endanger
adjacent personnel, clear the air hose of accumulated
dust and moisture. Before connecting a tool to the air hose
or removing a tool from service or changing sockets, make
sure the air line is shut off and drained of air. This will
Safety Recommendations
prevent the tool from operating if the throttle is accidently
engaged.
When using right angle nutrunners, be sure the throttle is
positioned relative to the angle head so that the throttle will
not become 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 accommodate
proper location for task. If tool is to be reversed, locate
throttle lever in a neutral position that will prevent entrap-
ment. Refer to operating instructions for additional infor-
mation.
It is essential for safe operation that any operator of a
nutrunner use good balance, sure footing, and proper
posture in anticipation of a torque reaction.
Tools with clutches can stall rather than shut-off if adjusted
over maximum power output of tool, or if there is a drop in
air pressure. Operator must then resist stall torque until
throttle is released.
Tool balance arms are available to absorb the torque
reaction of the tool while balancing the weight of the tool
for improved ergonomic applications.
Some individuals may be susceptible to disorders of the
hands and arms when performing tasks consisting of
highly repetitive motions and/or exposure to extended
vibration. Cumulative trauma disorders such as carpal
tunnel syndrome and tendonitis may be caused or aggra-
vated by repetitious, forceful exertions of the hands and
arms. Vibration may contribute to a condition called
Raynaud's Syndrome. These disorders develop gradually
over periods of weeks, months, and years. It is presently
unknown to what extent exposure to vibrations or repeti-
tive motions may contribute to the disorders. Hereditary
factors, vasculatory or circulatory problems, exposure to
