Safety Recommendations
For your safety and the safety of others, read and understand the safety recommendations and operating instructions before operating a screwdriver.
Always wear protective equipment:
WARNING!
Impact resistant eye protection
must be worn while operating
or working near this tool.
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,
N.Y. 10036.
CAUTION!
Personal hearing protection is
recommended when operating
or working near this tool.
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 or 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 screwdrivers 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,
removing a tool from service or changing bits, 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.
CAUTION!
Tools with clutches can stall 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.
Higher torque screwdrivers can be equipped with grip
sleeves and dead handles. Tool balance arms are available to absorb the torque reaction of the tool while balancing the weight of the tool for improved ergonomic applications.
Poor quality fasteners and bits can cause vibration during
run down. Use quality fasteners and bits.
Some individuals may be susceptible to disorders of the
WARNING
!
Repetitive work motions and/or vibration
may cause injury to hands and arms.
Use minimum hand grip force consistent
with proper control and safe operation.
Keep body and hands warm and dry.
Avoid anything that inhibits blood circulation.

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 aggravated 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 repetitive motions may contribute to the disorders. Hereditary
factors, vasculatory or circulatory problems, exposure to
cold and dampness, diet, smoking and work practices are
thought to contribute to the conditions.

OPERATING
INSTRUCTIONS
Any tool operator should be aware of the following warning
signs and symptoms so that a problem can be addressed
before it becomes a debilitating injury. Any user suffering
prolonged symptoms of tingling, numbness, blanching of
fingers, clumsiness or weakened grip, nocturnal pain in the
hand, or any other disorder of the shoulders, arms, wrists,
or fingers is advised to consult a physician. If it is determined that the symptoms are job related or aggravated by
movements and postures dictated by the job design, it may
be necessary for the employer to take steps to prevent
further occurrences. These steps might include, but are not
limited to, repositioning the workpiece or redesigning the
workstation, reassigning workers to other jobs, rotating
jobs, changing work pace, and/or changing the type of tool
used so as to minimize stress on the operator. Some tasks
may require more than one type of tool to obtain the
optimum operator/tool/task relationship.
The following suggestions will help reduce or moderate the
effects of repetitive work motions and/or extended vibration
exposure:
• Use a minimum hand grip force consistent with proper
control and safe operation
• Keep body and hands warm and dry (cold weather is
reported to be a major factor contributing to Raynaud's
Syndrome)
• Tasks should be performed in such a manner that the
wrists are maintained in a neutral position, which is not
flexed, hyperextended, or turned side to side.
• Stressful postures should be avoided — select a tool
appropriate for the job and work location
• Avoid highly repetitive movements of hands and wrists,
and continuous vibration exposure (after each period of
operation, exercise to increase blood circulation)
• Keep tool well maintained and replace worn parts
Work gloves with vibration reducing liners and wrist supports are available from some manufacturers of industrial
work gloves. Tool wraps and grips are also available from
a number of different manufacturers. These gloves, wraps,
and wrist supports are designed to reduce and moderate
the effects of extended vibration exposure and repetitive
wrist trauma. Since they vary widely in design, material,
thickness, vibration reduction, and wrist support qualities,
it is recommended that the glove, tool wrap, or wrist support
manufacturer be consulted for items designed for your
specific application. WARNING! Proper fit of gloves is
important. Improperly fitted gloves may restrict blood
flow to the fingers and can substantially reduce grip
strength.
For more information on the safe use of portable air tools,
see the latest edition of ANSI B186.1, Safety Code for
Portable Air Tools, available from the American National
Standards Institute, Inc. 11 West 42nd Street, New York,

OPERATING & SERVICE INSTRUCTIONS
The No. 88C Series CLECOMATIC screwdrivers are push-to
start, automatic shutoff tools. Accurate torque is achieved by
setting the CLECOMATIC clutch to the desired torque. The tool
will automatically shut off at this preset torque. Removing the
tool from the work piece will reset the tool for the next cycle.
NOTE: The 88C SAPT and 88C RSAPT models are equipped
with a trigger which must be depressed before the push-to-start,
automatic shutoff cycle will begin. The 88C RSAL models are
equipped with a lever which must be depressed before the
push-to-start, automatic shutoff cycle will begin.
CLUTCH ADJUSTMENT
Unscrew (left hand threads) the clutch housing, from the gear
case. Tighten the adjustment nut (clockwise) to increase torque
and loosen (counterclockwise) to decrease the torque output of
the tool.
CAUTION
!
If the clutch is adjusted over the maximum power output of the
tool, the clutch will not function and the tool will operate like a
stall-type tool. Also, if the tool is being operated at its upper
torque limits, a drop in air pressure could cause the clutch not
to function due to a loss of motor power and the tool will function
like a stall-type tool. While resisting torque operator must
remove tool from fastener to shut off tool.
OPERATIONAL CHECK: Grip tool securely and be prepared to
counteract stall torque if clutch is improperly adjusted.
AIR SUPPLY
The tool is designed to operate at 90 psig air pressure. The air
pressure should be checked at the tool's air inlet while the tool
is running.
For maximum performance, use a 1/4" I.D. air hose up to 8' in
length. If additional length is required, a 3/8" I.D. or larger hose
should be connected to the 1/4" I.D. hose. The air hose should
be cleared of accumulated dirt and moisture.
Application of the tool should govern how frequently it is
greased. It is recommended that the idler gears receive a
generous amount of NLGI 2-EP grease after every 40 hours of
operation. The clutch housing (left hand threads) and clutch
must be removed and the grease applied through the hex in the
spider.
DISASSEMBLY — GENERAL (All Models)
Clamp the backhead in a soft-jawed vise and unscrew (left hand
threads) the clutch housing and remove the clutch assembly.
Unscrew and remove the gear case assembly. The trip rod and
motor unit may now be removed from the front of the backhead.
See the following paragraphs for complete disassembly instructions on the various sub-assemblies.
CLUTCH DISASSEMBLY
Unscrew the adjustment nut, No. 202755. This will allow the
adjustment plate, No. 202754, thrust bearing, No. 847596,
thrust race, No. 202753, torque spring, release spring, No.
202752, release sleeve, No. 203271, two (2) steel balls, No.
8842161, ball retainer No. 203272 and five (5) steel balls to be
removed from the clutch spindle assembly. Wash the spindle
assembly in a solvent and rotate the cam, No. 203270, to
remove as much grease as possible. Remove the retainer ring,
No. 202749, ball plug, No. 202748, and twelve (12) steel balls,
No. 842161, from the cam. This will allow the trip plunger, No.
202745, reset spring, No. 202746, and pin, No. 843231, to be
removed from the rear of the clutch spindle.
GEAR CASE DISASSEMBLY
The spider should be pressed out the rear of the gear case, No.
867907. Remove the retainer ring, No. 844364, and press the
bearing, No. 847147, out the front of the gear case.
If replacement of the idler gear pins is necessary, they should
be pressed out the rear of the spider. See drawings below for
replacement pin height. The pin height on the gear case spiders
are the same as the 1st reduction spider below.
LUBRICATION
An automatic in-line filter-lubricator is recommended as it increases tool life and keeps the tool in sustained operation. The
in-line lubricator should be regularly checked and filled with a
good grade of 10W machine oil. For proper adjustment of the
in-line lubricator, place a sheet of paper next to the exhaust
ports and hold the throttle open approximately 30 seconds to
one minute. The tool is receiving adequate oil when a light stain
appears on the paper. If the oil mist is visible to the naked eye
it is generally an excessive amount of oil. Excessive amounts of
oil should be avoided.
In the event that it becomes necessary to store the tool for an
extended period of time (overnight, weekend, etc.), it should
receive a generous amount of lubrication at that time and again
when returned to service. The tool should be stored in a clean
and dry environment.
