adding new meaning to user friendly in efforts to improve power tool user comfort levels some operational factors deserve special attention noise process airflow and vibration-induced noise from pneumatic tools should be within osha and iso standards double chamber pulse unit large drive locating diameters limit extension run-out to reduce vibration top air inlet to allow air drops from above enabling proper workstation setup dust an avoidable byproduct of grinding and other operations fine dust particles should be collected and trapped by a vacuum source near the workstation before they are absorbed into workers lungs torque reaction industry consensus is that 100 inchpounds is the maximum torque that should be delivered use of high pressure low pressure pulse low-force start trigger mechanism handle coating for operator comfort acceleration via tool software coded with hard algorithms operator detection of speed shifts is avoided the result is less fatigue to the operator and consistent torque transmission to the assembly task hydraulic blades housing control blades the hydraulic pulse unit of our cleco pulse tools nearly absorbs all the torque reaction that is normally felt by an operator ultimately worker productivity is improved bottom air inlet quiet exhaust reduces noise bucking bars and torque-absorbing mounting accessories can help reduce torque buck vibration dynamically balanced true-running wheels can help reduce vibration in power tools with the goal of avoiding the extreme amounts of vibration which can disturb the flow of blood to the hand and cause white finger this diagnostics screen of the cleco tightening manager displays an oscilloscope style torque trace of the joint to help identify potential assembly process problems some higher torque tools incorporate torque reaction bars which transmit the reaction to a solid fixture rather than the operator for improved production and safety tool arms absorb the torque produced by the tool eliminating torque reaction to the operator balanced by springs or air cylinders the arm and not the operator supports the weight and reaction of the tool by reducing the fatigue factors the operator productivity is improved arms can be post mounted wall mounted or mounted on an adjustable height post tool holders for all models will accommodate most major brands of air tools straight and pistol tool holders allow the tool to swing swivel and rotate enabling the operator to work more comfortably and productively.
