Installation Instructions

Mounting Procedure

1. Select two appropriate suspension points above the workstation to prevent skewing.
2. Connect the safety chain first before hanging the balancer.
3. Attach the fixing pipe to the suspension point.
4. Ensure the mounting surface can support at least 1.5 times the maximum load capacity.

Wire Rope Setup

1. Extend the wire rope fully before first use.
2. Check for smooth retraction without binding.
3. Verify the anti-collision rubber sleeve is properly positioned.

Operation Guide

Tension Adjustment

1. To Increase Tension: Rotate the adjustment knob counterclockwise.
2. To Decrease Tension:
   • Disconnect the fixed pipe.
   • Rotate the knob clockwise.
   • Reconnect the fixed pipe.

Height Locking

1. Pull down the suspended object to desired working height.
2. Engage the manual locking mechanism using the positioning clip.
3. For SBA/SB series: Adjust the screw to set lock distance (approximately 10cm from starter).
4. Secure the locking screw firmly.

Normal Operation

• The balancer will automatically maintain tension to support your tool.
• Tools should float freely within the weight capacity range.
• Smoothly guide tools up or down without forcing movement.

Safety Warnings

Critical Safety Instructions

1. Never exceed the specified weight capacity for your model.
2. Always connect the safety chain before suspending any load.
3. Do not operate without a suspended object as this may damage the wire rope.
4. Inspect the wire rope regularly for signs of wear, fraying, or damage.
5. In case of spring failure, the safety lock will engage automatically – do not attempt to bypass this feature.
6. Ensure mounting points are secure and can handle dynamic loads.
7. Keep hands clear of moving parts during operation.
8. Do not modify or alter any safety mechanisms.

Operational Precautions

• Avoid sudden impacts or jerking motions.
• Do not allow the wire rope to completely retract with no load.
• Keep the unit clean and free from excessive dust or debris.
• Operate within specified temperature ranges (-10°C to +40°C).

Maintenance & Care

Regular Inspection

• Daily: Check wire rope condition and smooth operation.
• Weekly: Verify locking mechanism functionality.
• Monthly: Inspect mounting hardware and safety chain.
• Quarterly: Lubricate moving parts if necessary (use light machine oil).

Cleaning

• Wipe exterior with a clean, dry cloth.
• Remove dust from the wire rope with a soft brush.
• Do not use solvents or corrosive cleaners.
• Keep the anti-collision rubber sleeve clean and flexible.

Storage

• Store in a dry environment away from direct sunlight.
• Fully retract the wire rope when not in use for extended periods.
• Hang vertically to prevent wire rope deformation.
