Need help?Do you have a question about the EINHELL TE-RH 40 3F and is the answer not in the manual?
The Einhell TE-RH 40 3F is a robust rotary hammer designed for demanding drilling and chiseling tasks in concrete, rock, and brick. This tool is engineered for efficiency and user comfort, featuring a range of functionalities that make it suitable for various construction and renovation projects.
The primary function of the TE-RH 40 3F is impact drilling, which allows it to bore into hard materials like concrete and stone with ease. It also excels at chiseling work, making it versatile for breaking and shaping these materials. The tool is equipped with a selector switch (4) that allows the user to choose between different operating modes: impact drilling and chiseling. This versatility ensures that the tool can adapt to various job requirements. For hammer drilling, the user presses button (E) on the rotary switch (4) and simultaneously turns the rotary switch (4) to position A. For chiseling, the process is similar; pressing button (E) and turning the rotary switch (4) to position B allows for chiseling where the chisel is not locked. If a locked chisel position is required for specific tasks, the user can press button (E) and turn the rotary switch (4) to position C. This ensures precise control over the chisel's orientation during operation.
The TE-RH 40 3F incorporates an electronic speed control system, enabling users to preselect the desired speed by turning the speed controller (8). This feature is crucial for adapting the tool's performance to different materials and applications, ensuring optimal results and preventing damage to the workpiece or the tool itself. The speed can be increased by turning the controller in the plus direction and decreased by turning it in the minus direction.
Safety and user comfort are paramount in the design of the TE-RH 40 3F. The tool is equipped with an additional handle (3), which is essential for safe operation. For safety reasons, the hammer drill must only be used with this additional handle attached. The handle provides better stability and control, especially during high-impact tasks, significantly reducing user fatigue and improving precision. The additional handle (3) is secured by a clamp mechanism. To adjust its position, the user turns the handle anti-clockwise to release the clamp, allowing the handle to be swung into the most comfortable working position. Once the desired position is achieved, turning the handle clockwise tightens the clamp, securing it firmly.
The tool features a quick and secure tool insertion and removal system. To insert a tool, the user first cleans the tool and applies a thin coating of drill bit grease to its shaft. Then, the locking sleeve (2) is pulled back and held while the dust-free tool is inserted into the tool mounting as far as it will go, turning it slightly until it locks itself. A quick pull on the tool confirms that it is properly secured. For removal, the locking sleeve (2) is pulled back and held, allowing the tool to be easily extracted. This system ensures efficient tool changes, minimizing downtime during work.
The On/Off switch (6) controls the power to the tool. For continuous operation, the On/Off switch (6) can be secured with the switch lock (5), allowing the user to maintain power without constantly holding the trigger. To switch off the tool, the On/Off switch (6) is simply pressed.
Regular cleaning and maintenance are crucial for ensuring the longevity and optimal performance of the TE-RH 40 3F. Users should always pull out the mains power plug before starting any cleaning work to prevent accidental activation.
All safety devices, air vents, and the motor housing should be kept free of dirt and dust. This can be achieved by wiping the equipment with a clean cloth or blowing it with compressed air at low pressure. It is recommended to clean the device immediately after each use. For more thorough cleaning, a moist cloth and some soft soap can be used. However, it is important to avoid cleaning agents or solvents, as these can damage the plastic parts of the equipment. Care must also be taken to ensure that no water seeps into the device, as water ingress can increase the risk of an electric shock.
The carbon brushes, which are wear parts, should be checked by a qualified electrician in case of excessive sparking. Carbon brushes should only be replaced by a qualified electrician to ensure proper functioning and safety. The equipment itself does not contain any parts that require additional maintenance by the user.
When ordering replacement parts, it is important to quote specific data: the type of machine, the article number of the machine, the identification number of the machine, and the replacement part number of the required part. This ensures that the correct parts are ordered, maintaining the tool's integrity and performance.
The TE-RH 40 3F is designed for robust performance and ease of use, making it a reliable tool for professionals and DIY enthusiasts alike. Adhering to the operating and maintenance instructions will ensure its safe and efficient operation for many years.
