Overview

The Festool HL 850 electronic planer is a versatile tool designed for a wide range of woodworking applications, from achieving smooth finishes to milling edges and creating rebates. Its unique design, featuring a planing head mounted on one side, allows for the creation of rebates in wood to almost any desired depth, a capability that sets it apart from standard planers. This feature is particularly useful for furniture making and interior finishing, where rebates are frequently required.

To effectively use the HL 850 EB-Plus planer for creating rebates, a specific procedure is recommended. Before starting, it is advisable to connect a dust extractor with a large container, such as the Festool CLEANTEC CTM 36 E, to manage the wood chips produced during planing. This setup is more economical in the long run compared to using SELFCLEAN filter bags alone, as a pre-separator can be fitted to collect the chips efficiently.

The first step in creating a rebate involves setting the desired rebate depth. This is achieved by measuring the exact distance from the planer foot to the rebate depth stop. To facilitate this measurement and ensure precision, the tool should be placed on its side with the rebate depth stop facing upwards. This orientation allows for an accurate setting, which is crucial for achieving a precise rebate in the wood.

Once the depth is set, the actual planing process begins. The chip thickness should be set to 1 mm for the initial pass. During this first work step, it is essential to guide the planer so that the parallel side fence fits precisely along the wood. This initial pass is critical for accurately positioning the rebate, ensuring that subsequent passes build upon a well-defined starting point. The precision of this first step directly impacts the overall accuracy and quality of the finished rebate.

After the first pass, the procedure changes slightly for subsequent work steps. From the second pass onwards, the edge of the planer foot is placed against the newly formed rebate edge. This means that the parallel side fence, which was crucial for the initial positioning, is no longer necessary and can be removed. The focus shifts to maintaining a consistent guide along the rebate edge with the planer foot. It is imperative to ensure that the edge of the planer foot is always guided exactly along the rebate edge to maintain the straightness and consistency of the rebate.

The planing continues until the rebate depth stop makes contact with the workpiece. At this point, the set rebate depth has been reached, indicating that the desired depth has been achieved. The planer is designed to stop at this point, preventing over-planing and ensuring the rebate is exactly as deep as intended. However, if the rebate depth stop is not used, the planer offers the flexibility to plane the rebate as deep as the user chooses, providing greater control for specialized applications that may require deeper cuts.

The HL 850 EB-Plus planer is designed for ease of use and precision, making it suitable for both experienced professionals and those new to woodworking. Its robust construction ensures durability, while its ergonomic design contributes to comfortable handling during prolonged use. The ability to create rebates of almost any depth, combined with the detailed guidance on setting up and operating the tool, makes it an invaluable asset for a variety of woodworking projects.

For maintenance, while specific details are not provided in the manual excerpt, the general recommendation for using a dust extractor suggests that keeping the tool clean and free of debris is important for its longevity and performance. Regular cleaning of the planing head and other moving parts would likely contribute to maintaining its precision and operational efficiency. The emphasis on safety instructions in the "Please note" section also implies that proper handling and adherence to the operating manual are crucial for both user safety and the tool's upkeep.

In summary, the Festool HL 850 electronic planer is a high-performance tool distinguished by its unique planing head, enabling the creation of deep and precise rebates. Its operation involves careful depth setting, precise initial guidance with a parallel side fence, and subsequent passes guided by the rebate edge. The integration with a dust extractor enhances the working environment and contributes to the tool's maintenance. This planer is a testament to Festool's commitment to providing versatile and efficient solutions for complex woodworking tasks.
