4. Operating Instructions

The Lewmar 89400108 Control Mechanism is designed for intuitive operation. The cranked handle provides a tactile interface for controlling various marine functions, typically related to steering or other mechanical adjustments on a vessel.

4.1 Basic Operation

• To engage the control function, grasp the cranked handle firmly.
• Rotate the handle in the desired direction to initiate the corresponding action (e.g., steering adjustments, throttle control, or other mechanical linkages).
• The non-magnetic properties ensure minimal interference with sensitive navigation equipment.

4.2 Safety Precautions

• Always ensure the area around the control mechanism is clear before operation.
• Avoid applying excessive force to the handle, as this may damage the mechanism or connected components.
• Regularly check for smooth operation and any signs of wear or damage.

5. Maintenance

Proper maintenance is crucial for the longevity and reliable performance of your Lewmar Control Mechanism.

5.1 Routine Cleaning

• Clean the stainless steel crank handle and the mechanism housing regularly with fresh water and a mild soap solution.
• Rinse thoroughly to remove all soap residue.
• Avoid abrasive cleaners or solvents that could damage the finish or internal components.

5.2 Inspection

• Periodically inspect all fasteners for tightness. Re-tighten as necessary, but do not overtighten.
• Check the crank handle for any signs of bending, cracking, or excessive play.
• Inspect the mechanism for smooth operation. If stiffness or grinding is noted, consult a qualified technician.
• Examine the mounting area for corrosion or structural fatigue, especially in a marine environment.

6. Troubleshooting

This section addresses common issues you might encounter with your control mechanism.

6.1 Handle Stiffness or Binding

• Cause: Accumulation of dirt, salt, or corrosion; misaligned components; worn internal parts.
• Solution: Clean the mechanism thoroughly. Check for proper alignment during installation. If the issue persists after cleaning and alignment checks, professional inspection may be required.

6.2 Loose Handle or Excessive Play

• Cause: Loose fasteners; worn shaft or bearing.
• Solution: Check and tighten all mounting fasteners. If the handle itself is loose on its shaft, inspect the connection point for wear. If wear is significant, replacement of the handle or internal components may be necessary.

6.3 Mechanism Not Responding

• Cause: Disconnected linkage; internal component failure.
• Solution: Verify that all linkages between the control mechanism and the controlled device are securely connected. If the issue is internal, professional service is recommended.
