Installation Steps
-
Confirm installation location and space requirements
- Ensure the mounting surface is flat and sufficiently strong
- Reserve appropriate space for piping and wiring
- Verify required installation space based on the model, especially considering the long stroke Characteristics
-
Secure the gripper body
- Use appropriate screws to fix the gripper to the mounting surface
- Select the correct mounting screw specifications based on bore size
- Ensure secure installation to avoid accuracy issues due to looseness
-
Install fingers and accessories
- Install appropriate fingers or fixtures based on application requirements
- Secure fingers using the finger mounting threaded holes
- Ensure parallel and symmetrical installation of fingers
- For long stroke models, pay special attention to the rigidity and stability of the fingers
-
Piping connection
- Confirm the opening/closing direction of the gripper
- Connect to air ports using appropriate air tubes and fittings
- Ensure proper piping seal to prevent leaks
- For long stroke models, pay attention to the length and arrangement of air tubes to avoid motion interference
-
Magnetic switch installation (optional)
- Install magnetic switches if position detection is required
- Adjust switch position for accurate finger position detection
- For long stroke models, multiple switches may be required to detect different positions

Operation Guide
-
Pre-start checks
- Confirm air supply pressure is within the specified range
- Check for correct piping connections
- Ensure operating temperature is within the allowable range
- Verify proper installation of fingers and fixtures
- For long stroke models, specially check for any interference in the finger movement range
-
Basic operation
- Control finger opening/closing by supplying and exhausting compressed air
- Double acting type:
- Finger opening: Compressed air enters from the "open port"
- Finger closing: Compressed air enters from the "close port"
- Single acting type (normally open):
- Finger closing: Compressed air enters from the "close port"
- Finger opening: Exhaust air, relying on spring force
- Single acting type (normally closed):
- Finger opening: Compressed air enters from the "open port"
- Finger closing: Exhaust air, relying on spring force
-
Gripping force adjustment
- Adjust gripping force by regulating operating air pressure
- Higher air pressure results in greater gripping force
- Select appropriate gripping force based on workpiece weight and material
- Ensure sufficient gripping force to prevent workpiece slippage, but not excessive to cause workpiece deformation
- For long stroke models, note that gripping force may vary at the end of the stroke
-
Stroke adjustment
- The MHZL2 series offers fixed long stroke designs
- Select appropriate bore size and stroke length based on requirements
- Ensure stable workpiece gripping throughout the entire stroke range
- Note maximum stroke limitations for different bore sizes

Maintenance
-
Daily inspection
- Check for piping leaks
- Verify smooth operation of the gripper
- Inspect fingers and fixtures for wear or damage
- Confirm proper operation of magnetic switches (if installed)
- For long stroke models, specially check the wear condition of guide rails and sliders
-
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 operating status of magnetic switches
- Perform comprehensive functional testing
- Annually:
- Inspect the condition of seals
- Replace worn components
- For long stroke models, check the precision and wear condition of guide rails and sliders
- Every 3 months:
-
Lubrication
- The MHZL2 series is designed for maintenance-free operation and typically does not require additional lubrication
- For long-term use or in harsh environments, add an appropriate amount of lubricating oil as needed
- Use the recommended lubricant type and avoid incompatible lubricants
- For long stroke models, pay attention to the lubrication of the guide rail part

Safety Precautions
- Carefully read this user guide before operation
- Ensure air supply pressure is within the specified range to avoid equipment damage or safety accidents due to excessive pressure
- Cut off the 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 detect and address potential issues promptly
- Immediately stop use and perform inspections if abnormal conditions are detected
- Ensure workpieces are securely gripped before handling or processing
- For long stroke models, pay special attention to the movement range of fingers to avoid collisions and interference
- Avoid placing fingers or other body parts within the working range of moving components
- Use appropriate safety protection devices, such as protective covers or safety light curtains
