The CS45 is a ¼″ hex‐shank, straight-handle pneumatic screwdriver from Sumake featuring a cushion clutch (slip clutch) mechanism. Its straight‐handle design makes it favourable for assembly operations where access is restricted or where the operator needs a low‐profile tool. The cushion clutch allows repeatable torque control by “slipping” once the preset torque is reached, helping avoid over‐tightening and reducing operator fatigue.
Features
:- Cushion / slip clutch mechanism : The tool slips when the preset torque is reached, providing a tactile “give” to prevent over-tightening.
- Torque range of ~8.9-62.0 in-lb (≈1.0-7.0 N·m) : Enables a wide range of fastening applications within that range.
- Lever start : Operated with a lever rather than only a trigger, giving better control of start/stop.
- Forward/Reverse switch : Allows both tightening and loosening operations.
- Ergonomic grip : Thermoplastic elastomeric grip “Top Wave” design provides a comfortable, non‐slip handle feel.
- Compact and lightweight body : Length about 140 mm (5.5 inches), weight ~600 g (1.3 lb) in this class.
- Air inlet ¼″ and bit shank ¼″ hex : Standard fittings for pneumatic assembly tools.
- Low vibration & low noise operation : Suited for repeated use in production/assembly lines.
Applications
:- Electronics assembly – fastening small machine screws or sheet-metal screws where consistent torque is required.
- Automotive component assembly – e.g., fastening brackets, sensors, interior trim where ¼″ hex tools suffice and over-tightening must be avoided.
- Appliance and white-goods manufacturing – repeatable fastening of many identical components, benefiting from clutch slip to prevent damage.
- General manufacturing / production lines – tasks requiring moderate torque (< ~7 N·m) and ergonomic tool use for operator comfort.
- Maintenance and repair operations where a straight-handle compact screwdriver is needed for tighter spaces.
Usage
:Air supply setup :
- Connect tool to a clean, dry compressed air supply. Recommended working pressure around 85 psi (~6 bar) as per specification.
- Fit an air filter, regulator and lubricator (FRL) to ensure the air is well-filtered and lubricated—essential for pneumatic motor longevity.
- Use appropriate air hose (minimum ID recommended by manufacturer) and quick‐coupler for mobility.
Tool and bit preparation :
- Insert a ¼″ hex shank bit (impact rated if required) securely into the tool’s chuck/bit holder.
- Select and set the torque setting: the external dial (in some cushion‐clutch models) allows adjustment to match fastener requirements. Ensure correct torque setting so that the clutch will slip at the desired value.
- Check reverse/forward switch is set for desired direction (tightening or loosening).
Operation :
- Hold the tool firmly but not rigidly; align bit to fastener head squarely to avoid cam-out or damage.
- Activate the lever start, allowing full speed to build, and push the tool into the fastener only as needed. Avoid applying excessive side loads.
- For tightening: allow the tool to drive until the clutch slips or the sound/feel indicates the preset torque is reached. For loosening: use reverse and pull smoothly.
- After completing an operation, release trigger, switch off air, inspect fastener or joint for correct torque/fit.
Safety & environment :
- Wear eye protection and hearing protection (even though noise may be low, repetitive use still warrants protection).
- Ensure the workspace is free of obstructions; avoid tangled hoses.
- Ensure ventilation if using in an enclosed space; also ensure bit/socket is correct size to avoid damage.
- Disconnect air supply when the tool is idle or for maintenance.
