clecomatictm screwdrivers clecomatic screwdrivers improve productivity operator performance and finished product quality every clecomatic product feature is designed for higher production and increased productivity with high power-to-weight ratios clecomatic screwdrivers reduce cycle time from fastener to fastener and operators prefer the lighter more powerful tool on many applications a higher speed tool can be used for faster rundown and because of the automatic shut-off feature will provide consistent torque repeatability clecomatic screwdrivers allow the operator to remove the tool from the fastener instantly after shut-off clecomatic tool t o ta ltimeper fa stener torque because no dwell time is needed to reach torque thereby increasing productivity by as much as 10 the automatic stop feature also prevents unnecessary bit rotation and extends bit life up to 25 times or longer than the average life of bits used in ratcheting tools other benefits provided by quality clecomatic screwdrivers are lower scrap improved product quality reduced warranty claims and costly rework tool positioning fastener rundown dwell tool removal clecomatic tools improve operator performance reduce operator fatigue clecomatic tools have been designed from the inside out to make your operators more efficient and productive while helping to minimize the fatigue associated with high volume assembly operations reduced torque reaction absence of vibration quieter operation ease of starting compact size high power-to-weight ratio better tool feel and balance and greater reliability are some of the benefits clecomatic tools provide for operators couple these advantages with more power per pound which reduces operator fatigue along with a tool that is easy to handle and more efficient ratcheting clutch screwdriver 60 month warranty cleco® 14 8 series clecomatic® screwdrivers cooper power tools warrants the 14 and 8 series clecomatic screwdrivers and parts to be free from defects in workmanship and material of the life of the tool the clutch assemblies are warranted for sixty months against failure or wear causing malfunction cooper power tools obligation under this warranty is to repair or replace without charge to the original purchaser any part which does not meet the warranty outlined above during the active commercial production of this tool this tool is to be returned to the factory with carrying charges prepaid this warranty shall not apply to any product that has been fixture mounted or subjected to misuse negligence or accident or in which parts not made or supplied by cooper power tools shall have been used or which shall have been altered or repaired by other than cooper power tools personnel in a manner which in the determination of cooper power tools shall have affected its operation this warranty constitutes the entire obligation of the company relating to the sale and use of such product and its maximum liability is limited to the purchase price of such product in no event shall the company be liable for consequential indirect incidental or special damages of any nature arising from the sale of use of such product low power to weight tool t o ta ltimeper fa stener time saved time clecomatic clutch operation pre-start in the pre-start position air pressure forces the shutoff valve forward and seated preventing live air from reaching the motor in turn the clutch assembly is forced forward to the front of the clutch housing by the trip rod torque clecomatic screwdriver pre-start rundown shutoff shutoff valve remains seated shutoff valve closes reset because clecomatic tools do not ratchet the operator is not subjected to tiring shock vibration and excessive torque reaction the torque time graphs at left illustrate how clecomatic tools reduce the length of time an operator spends counteracting the ratcheting effect of other screwdrivers rundown shutoff valve seated as the operator pushes the tool against the workpiece the clutch is forced back into the clutch housing unseating the shutoff valve and allowing live air to reach the motor during rundown spring force holds balls within the clutch assembly firmly down in valleys between lobes of the clutch cam causing the reverse motor gear train and clutch assembly to valve rotate as one unit to tighten the fastener shutoff valve unseated operators using clecomatic tools are exposed to far less tool noise providing an improvement in their working environment the automatic start/stop feature means that the tool runs only while the fastener is being tightened when the tool shuts off the fastener is accurately seated and there is virtually no clutch ratcheting reducing the operator s exposure to tool noise by as much as 80 time the cost saved in reduced air consumption alone can easily cover the cost of a clecomatic screwdriver over its service life up to five times longer life fewer replacement parts and lower service costs make clecomatic screwdrivers a true value in quality the major benefit offered by clecomatic screwdrivers is their extremely long service life as with other quality products their cost should be measured in terms of years of service maintenance costs for parts and labor and on-the-job performance measurably longer life of clecomatic screwdrivers has been achieved through simplicity of design requiring fewer moving parts coupled with the smooth rolling action of large diameter clutch balls that increase load bearing surfaces for longer clutch life also the use of fewer parts allows the size and wall thickness of the vital components to be beefed up for greater strength and durability these patented design features along with high quality close tolerance motors and rugged gear components extend the interval between service and reduce replacement parts cost the warranty covering the 14 and 8 series clecomatic screwdrivers is further proof that these cleco tools last longer 37 shutoff the torque at which the clutch shuts the tool off is determined by the amount of compression force exerted by the torque spring this torque is preset and can be torque adjusted externally by either compressing spring or relaxing the torque spring in order to increase or decrease torque output at the critical moment that the desired output torque on the fastener is reached two things happen 1 the balls roll over the top of the cam lobes disengaging the spindle from the motor reducing the influence of inertia clutch assembly from the spinning motor in forward 2 the clutch spindle cam forces the position trip slide far enough to the side to allow a dowel pin to move forward through a hole in the trip slide this allows the shutoff valve to seat shutting off the tool pin shifts forward trip slide resets trip slide shifts to side clutch assembly forced back balls roll over cam clutch assembly returns to forward position type of screwdriver motor noise during positioning of tool none none motor noise while driving fastener motor and clutch noise during dwell none clecomatic push-to-start ratcheting lever-operated ratcheting reduce energy costs as much as 85 bit engaged torque achieved reset when the tool is removed from the workpiece the clutch moves forward in the housing and two small springs reverse the linear motion of the previous step allowing the trip slide to return to its operating position clecomatic screwdrivers save energy costs time studies on air consumption conducted with several types of screwdrivers have shown that the time a tool is using air can be decreased from 4.0 seconds to .6 seconds per fastener cycle lowering the cost of compressed air by 85 over lever operated ratcheting screwdrivers 36
