Picote Maxi Miller shafts and leaders can break during use due to several factors, primarily related to improper operation and maintenance. These include excessive force, incorrect rotational direction, worn-out parts, and insufficient lubrication.
Specific reasons for breakage:
- Excessive force: Pushing the tool with too much force, rather than allowing it to work at its intended speed, can cause the shaft and leader to bend, twist, or break.
- Incorrect rotational direction: The Maxi Miller is designed for clockwise rotation (forward) for optimal torque. Using anticlockwise rotation (reverse) for extended periods can lead to shaft failure.
- Worn-out parts: Regular inspection of the shaft and leaders for damage, wear, or loose parts is crucial. If fastener screws are worn, they should be replaced immediately.
- Insufficient lubrication: The flexible shaft requires lubrication to reduce friction and prevent wear. Lack of proper lubrication can lead to increased stress on the shaft and eventual breakage.
- Overheating: If the motor overheats due to insufficient cooling or overloading, it can affect the shaft and lead to failure.
- Incorrect pipe size or material: Using the Maxi Miller in pipes that are too small or made of a material it’s not designed for can cause excessive strain on the shaft and leader.
- Damage during installation or removal: Improper handling during the installation or removal of the tool can also lead to damage.
- Using the tool outside the pipe: Never power on the Maxi Miller outside the pipe. The tooling needs to be fully inserted before powering on, to prevent damage to the shaft and leader.
Preventing breakage:
- Follow operating instructions: Adhere to the manufacturer’s recommendations for speed, force, and rotational direction.
- Regularly inspect: Inspect the shaft, leaders, and other components for wear and damage before each use.
- Lubricate the shaft: Apply lubricant to the flexible shaft as recommended by the manufacturer.
- Ensure proper cooling: Ensure the motor has sufficient cooling and that vents are not blocked.
- Use the correct tooling for the pipe: Select the appropriate Maxi Miller size and accessories for the specific pipe diameter and material.
- Replace worn parts promptly: Replace any worn or damaged parts immediately.
- Handle with care: Be cautious when installing and removing the tool to avoid damage.
