CAUTION

!

Personal hearing protection is 
recommended when operating 
or working near this tool.

SafetyRecommendations

Never use the air hose for supporting, lifting, or lowering the tool.
Use a safety line or cable on the tool when working in elevated
areas.

Tools with exposed throttles should not be used where obstruc-
tions can hold the throttle in the "on" position. An impact wrench
operating in reverse will move backwards as a nut is removed
and can trap an operator's hand, making it difficult to release an
outside trigger. Inside trigger or pistol grip tools are advised for
close quarter operation.

Only use sockets designed for use with impact wrenches. Never
use a hand tool socket on an impact wrench. Hand tool sockets
can break, resulting in a hazard from flying pieces. Inspect
sockets, retainers, and drives regularly for wear or damage, and
replace as necessary. Worn sockets reduce power, cause drive
wear, and increase the chance for breakage and should not be
used.

Impact wrenches equipped with the spline drive have an integral
socket retainer pin which may be depressed by a screwdriver or
similar tool when installing or removing a socket. Tools with
square drives 3/4" and larger use an aor- ring and pin for socket
retention. Retainers—either pin or integral—should be properly
engaged to prevent dropping sockets into lower working levels.
Always use socket retainer components recommended by the
socket manufacturer. Never substitute wire, nails, or welding
rods for retaining pins because they are dangerous if thrown
from the tool at free speed, or if the protruding nail or wire is
accidently grasped by the operator.

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 tendoni-
tis may be caused or aggravated by repetitious, forceful exer-
tions of the hands and arms. Vibration may contribute to a
condition called Raynaud's Syndrome. These disorders de-
velop gradually over periods of weeks, months, and years. It is

For your safety and the safety of others, read and understand
the safety recommendations before operating an impact wrench.

Always wear protective equipment and clothing.

For additional information on eye protection, refer to Federal
OSHA Regulations, 29 CFR, Section 1910.133, Eye and Face
Protection, and ANSI Z87.1, Occupational and Educational Eye
and Face Protection. This standard is available from the Ameri-
can National Standards Institute, Inc., 11 West 42nd Street,
New York, NY 10036.

Hearing protection is recommended in high noise areas (above
85 dBA). Close proximity of additional tools, reflective surfaces,
process noises, and resonant structures can substantially con-
tribute to the sound level experienced by the operator. 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 OSHA Regulations, 29 CFR, Section 1910.95,
Occupational Noise Exposure, and American National Stan-
dards Institute, ANSI S12.6, Hearing Protectors.

• Gloves and other protective clothing should be worn as
   required, unless they create a greater hazard.

• Do not wear loose fitting clothing, or clothing that may
   restrict movement, become entangled or in any way
   interfere with the safe operation of the impact.

Cleco impact wrenches 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 highly 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 endanger adjacent person-
nel, clear air hose of accumulated dust and moisture. Before
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.
