The Dual Piston Straight Line Sander, Stock Number M574DB, is a pneumatic tool designed for sanding applications, offering efficient material removal and surface finishing. This owner's manual provides comprehensive information on its operation, maintenance, and safety, ensuring users can maximize its performance and longevity.
The sander operates by utilizing compressed air to drive a dual-piston mechanism, which in turn moves a sanding pad in a straight-line motion. This linear action is particularly effective for achieving smooth, uniform finishes on various surfaces, making it suitable for tasks ranging from preparing surfaces for painting to fine-finishing woodworking projects. The tool is designed to remove high spots and roughness efficiently, allowing users to progress from coarse to finer grits to achieve the desired surface quality. Its pneumatic operation ensures consistent power delivery, which is crucial for maintaining sanding efficiency and preventing premature wear.
Operating the Dual Piston Straight Line Sander requires adherence to specific guidelines to ensure safety and optimal results. Before connecting the tool to an air supply, it's essential to prepare the 1/4" Quick-disconnect Coupler Plug by wrapping it with pipe thread seal tape and threading it into the air inlet. A Quick-Disconnect coupler on a 3/8" ID air source hose then connects to the tool. For users not employing an automatic oiler system, a few drops of Pneumatic Tool Oil should be added to the airline connection before operation, and additional drops after each hour of continuous use. The air pressure from the compressor should be set to 90 PSI, and this recommended pressure should not be exceeded. It's also crucial to check for air leaks after connection and address any found before use.
During operation, users should avoid applying additional pressure to the machine, as this can slow down the pad speed, reduce sanding efficiency, and shorten the tool's life. The sander should be started off the workpiece, then set down evenly, and moved slowly back and forth in wide, overlapping areas. When finished sanding, it should be lifted off the workpiece before stopping the motor. The sanding process typically begins with an abrasive grit coarse enough to remove high spots and roughness, followed by additional sanding with progressively finer grits until the desired finish is achieved. It is important never to jump directly from a coarse grit to a fine grit in a single step.
The manual emphasizes several safety precautions. Users must read, understand, and follow all instructions and warnings. The work area should be kept clean and well-lighted, free from clutter, and away from damp or wet conditions. The tool should not be used in the presence of flammable gases or liquids, nor should combustible materials be near the tools. Common sense should prevail during operation, meaning loose clothing or jewelry should be avoided, and the tool should be operated at a safe distance from oneself and others. Children must be kept away from the work area and never allowed to handle the tool or its components. When not in use, the tool should be stored in a dry, locked location, out of reach of children and untrained persons. Approved eye protection is mandatory, and a suitable mask should be worn if dust is raised.
When operating, a firm grip with both hands is necessary, and the user should be positioned appropriately relative to the workpiece. Awareness of what lies directly underneath the work area is crucial, as the tool can quickly penetrate material. Limbs and body should be kept clear of the tool, and spectators must maintain a safe distance. The tool or air hose should never be pointed at anyone. Proper footing and balance must be maintained at all times, and users should avoid reaching over or across running machines or hoses. Operating the tool under the influence of alcohol or drugs is strictly prohibited. Before connecting the tool to the air supply, ensure the air is in the OFF position. Only accessories designed for use with the tool should be employed, and the tool should be disconnected from the air supply before changing accessories, performing service, or when not in use. Following air source manufacturers' directions for connecting regulators, filters, and other accessories is also important. Quick couplers should not be installed directly on the tool, as this can strain the air inlet threads; instead, they should be installed on a short length of air hose attached to the tool.
Regular maintenance is vital for the longevity and optimal performance of the Dual Piston Straight Line Sander. Before each use, the air motor should be lubricated with a good grade of air tool oil, and the compressor tank should be drained daily. Grit or gum deposits can reduce power, which can be corrected by cleaning the air strainer and flushing the tool with gum solvent oil. Water accumulation in the air supply line can lead to gumming and power loss, so draining water from hoses and the compressor tank before each use is essential. The air filter on the supply line should be cleaned, and the tool flushed with gum solvent or a 50/50 mix of air tool oil and kerosene. Disassembly may be necessary for thorough cleaning and re-lubrication.
Beyond daily checks, the tool should be inspected for damaged parts before each use. Any part that appears damaged, including issues with alignment, binding, broken components, or mounting fixtures, should be carefully checked to ensure proper operation. Damaged parts must be repaired or replaced by a qualified technician using original Performance Tool® replacement parts. Failure to do so can lead to accidents and will void the warranty. Only accessories intended for use with this tool and recommended by the manufacturer should be used.
The air source itself requires attention. Clean air at the correct pressure is recommended. While a maximum of 90 PSI at the tool is generally suitable, the compressor pressure may need to be increased to 100 PSI depending on the length of the air hose and other circumstances to ensure 90 PSI at the tool. Water in the air hose and compressor tank negatively impacts performance and can damage the air tool, necessitating regular draining of the air tank and filters. Hose lengths exceeding 25 feet can cause line pressure loss, which may require increasing the hose I.D. or compressor pressure to compensate. An in-line pressure regulator with a gauge is recommended if air inlet pressure is critical.
The manual also addresses troubleshooting common issues. If the tool experiences insufficient power, probable causes include dirty or clogged air passages, insufficient air supply, air leakage, or worn/damaged wear and tear parts. Solutions involve flushing and lubricating the tool, draining the air tank and supply line, increasing line pressure, using Teflon tape at fittings, checking for worn O-rings and seals, and replacing worn parts. If the tool won't start or stalls, the probable cause is pistons being out of alignment. This can be corrected by setting the sander on a solid surface or workbench, holding the forward knob and handle to draw the body of the tool back, pushing the shoe as far forward as possible. This action realigns the dual pistons and drive gear for normal operation and may need to be performed before each use, depending on the shoe position.
