Installation Steps
-
Confirm installation location and space requirements
- Ensure mounting surface is flat and sufficiently strong
- Reserve appropriate space for piping and wiring
- Confirm required installation space based on model
-
Secure the gripper body
- Use suitable screws to fix the gripper to the mounting surface
- Select appropriate mounting screw specifications based on different bore sizes
- Ensure secure installation to avoid precision issues due to looseness
-
Install fingers and accessories
- Install appropriate fingers or fixtures according to application requirements
- Fix fingers using finger mounting threaded holes
- Ensure fingers are installed parallel and symmetrically (2-finger) or evenly distributed (3-finger, 4-finger)
-
Piping connection
- Confirm the opening and closing direction of the gripper
- Connect to air ports using suitable air tubes and fittings
- Ensure piping is properly sealed without leaks
-
Magnetic switch installation (optional)
- Install magnetic switches if position detection is required
- Adjust switch position to accurately detect finger position

Operation Guide
-
Pre-start checks
- Confirm air supply pressure is within specified range
- Check piping connections for correctness
- Ensure operating environment temperature is within allowable range
- Verify proper installation of fingers and fixtures
-
Basic operation
- Control the opening and closing of fingers by controlling the supply and exhaust of compressed air
- Finger opening: Compressed air enters from the "open port"
- Finger closing: Compressed air enters from the "close port"
- 3-finger and 4-finger models achieve synchronized movement through a rack-and-pinion mechanism
-
Gripping force adjustment
- Adjust gripping force by regulating working air pressure
- Higher air pressure results in greater gripping force
- Select appropriate gripping force based on workpiece weight and material
- Ensure gripping force is sufficient to prevent workpiece slippage but not excessive to cause deformation
-
Stroke adjustment
- Choose appropriate stroke length as needed
- Ensure workpiece is stably clamped throughout the entire stroke range
- Note the maximum stroke limitations for different bore sizes

Maintenance
-
Daily inspection
- Check for piping leaks
- Confirm smooth operation of the gripper
- Inspect fingers and fixtures for wear or damage
- Verify proper operation of magnetic switches (if installed)
-
Regular maintenance
- Every 3 months:
- Clean the exterior of the gripper
- Check for loose mounting screws
- Inspect wear on fingers and fixtures
- Every 6 months:
- Replace grease
- Check the working status of magnetic switches
- Perform comprehensive functional testing
- Annually:
- Inspect seal condition
- Replace worn components
- Every 3 months:
-
Lubrication
- The MHS series is designed for maintenance-free operation and typically does not require additional lubrication
- For long-term use or in harsh environments, an appropriate amount of lubricating oil may be added as needed
- Use the recommended lubricating oil type and avoid incompatible lubricants

Safety Precautions
- Read this user guide carefully before operation
- Ensure air supply pressure is within specified range to avoid equipment damage or safety accidents due to excessive pressure
- Cut off air supply before installation and maintenance
- Avoid use in environments with corrosive gases, dust, or high temperatures unless the equipment is specially treated
- Do not exceed the rated load and operating frequency of the equipment
- Regularly inspect equipment status to identify and address potential issues promptly
- Immediately stop use and perform inspection if abnormal conditions are found
- Ensure workpiece is securely clamped before handling or processing
- Keep fingers and other body parts away from the working range of moving components
- Use appropriate safety protection devices, such as protective covers or safety light curtains
