Repairing a Makita DUH502 18V Cordless hedge trimmer under warranty with a faulty controler.
Education
Introduction
In today's workshop, we have a new challenge: a Makita Hedge Cutter DUH502, which requires warranty repair due to a reported malfunction. This particular unit is a cordless hedge trimmer that utilizes an 18V battery and has a versatile design, including a feature that allows the operator to adjust the angle for more comfortable trimming. However, the customer states that the machine isn't operational, so we need to diagnose and repair the issue.
Upon receiving the hedge trimmer, we powered it on, but it showed no signs of activity. The first troubleshooting step was to assess the switch mechanism, specifically the safety lever switch that must be engaged to operate the motor. Typically, these are the primary culprits in cordless and corded tools not functioning—sometimes, they simply do not activate correctly.
To begin our assessment, we needed to disassemble the machine carefully. The process involved removing two plastic covers and the handle to access the internal mechanisms. Starting at the end of the machine, we removed screws that secured the handle. We found springs and protective rubber mounts that act as dampers for the gearbox, which was similar to the 36V model.
As we delved deeper into the trimmer's innards, we examined the switches and control board, hoping to identify the source of the problem. One notable observation was a hot spot detected on the controller board using a thermal imaging camera. This indicated a potential failure within the controller itself, which was confirmed after further inspection. A defective controller is a more significant issue, requiring part replacement.
The cost of the controller was approximately €200, which is more than half the purchase price of the hedge trimmer itself, costing between €300 and €350. Thankfully, given that the customer claimed this was under warranty, the repair costs would not fall on him. It’s important to keep in mind that genuine parts for this Makita trimmer are readily available, which is not always the case with other brands.
During our assessment, it was crucial to ensure the motor and other electrical components were in good condition to prevent future operational issues. With the controller identified as the faulty part, we proceeded to order the replacement.
As we reassembled the hedge trimmer, we ensured all wiring was correctly positioned to avoid any electrical shorts. We applied a systematic approach in reconstructing the unit to guarantee all components fit perfectly. Once completed, the trimmer powered on seamlessly, and the operation was smooth, showcasing both the integrity of the repair and the quality of the Makita machine itself.
In conclusion, this process illustrated the importance of pinpointing faults accurately, understanding warranty implications, and ensuring operability of the tool. Makers like Makita stand out due to their commitment to repair and replacement, ensuring customers receive support rather than just a new product without any examination of the original fault.
