Overview

The Chicago Pneumatic CP870 Dual-Action Sander is a robust pneumatic tool designed for sanding applications, primarily utilizing a flexible disc fitted with abrasive paper. Its dual-action mechanism ensures efficient material removal and a smooth finish, making it suitable for various professional sanding tasks. The tool is powered by compressed air, emphasizing the importance of a clean and dry air supply for optimal performance and longevity.

For proper operation, the sander requires a consistent air supply of 90 psig (6.2 bar). Maintaining this pressure is crucial, as higher pressures can significantly reduce the tool's lifespan. The air line connection should adhere to specified pipe, hose, and fitting sizes, and it's explicitly advised against installing a quick coupler directly into the sander's throttle handle to prevent potential issues. Lubrication is also a key aspect of its usage; an air line lubricator with SAE #10 oil, adjusted to two drops per minute, is recommended. If a lubricator isn't available, air motor oil should be added to the inlet once a day to ensure smooth operation and prevent premature wear.

The design of the CP870 focuses on user safety and operational efficiency. It incorporates features that address common workplace hazards associated with pneumatic tools. For instance, the tool's sound pressure level is declared at 92.5 dB(A), and its vibration value is 5.7 m/s², indicating the need for appropriate personal protective equipment, such as hearing protection, to mitigate potential long-term health effects. The emphasis on maintaining a balanced body position and secure footing during operation highlights the importance of user stability to prevent slips, trips, and falls, which are major causes of serious injury.

The sander's usage features also include warnings about entanglement hazards. Users are advised to keep away from rotating drives and to avoid wearing jewelry or loose clothing that could get caught in the tool or its accessories. Specific warnings about neckwear and hair are provided to prevent choking and scalping, respectively. Direct contact with accessories during and after use should be avoided, and gloves are recommended to reduce the risk of cuts or burns. The manual also stresses the importance of using only proper accessory retainers and deep sockets to ensure secure attachment and prevent breakage.

Projectile hazards are another significant concern addressed in the manual. Users and anyone in the vicinity are required to wear impact-resistant eye and face protection during operation, repair, or maintenance. Even small projectiles can cause severe eye injuries, including blindness. The use of impact wrench sockets and accessories in good condition is critical, as worn or hand sockets used with impact wrenches can shatter. The manual also advises using the simplest hook-up possible, as long, springy extension bars and adapters can absorb impact power and potentially break, leading to projectiles. Operating the tool off the work surface is discouraged, as it can cause the accessory to run too fast and be thrown off, posing a serious injury risk. Furthermore, the manual warns about the dangers of over-torqued or under-torqued fasteners, which can break or loosen and become projectiles, emphasizing the need to check assemblies requiring specific torque with a torque meter.

Maintenance is a critical aspect of ensuring the CP870's longevity and safe operation. The manual recommends disassembling and inspecting the air motor and orbital assembly every three months if the tool is used daily. Damaged or worn parts should be replaced promptly. High-wear parts are specifically underlined in the parts list to draw attention to components that require more frequent inspection and potential replacement. To minimize downtime, a specific Tune-Up Kit (CA144954) is recommended, which includes essential parts for routine maintenance. This proactive approach to maintenance helps prevent unexpected breakdowns and ensures the tool remains in optimal working condition.

The manual also addresses various workplace hazards beyond direct tool operation. It warns about the dangers of inhaling dust or handling debris from the work process, which can be harmful to health. Consequently, the use of dust extraction systems and respiratory protective equipment is strongly advised when working with materials that produce airborne particles. The manual explicitly states that some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer and birth defects or other reproductive harm, citing examples like lead from lead-based paints, crystalline silica from masonry products, and arsenic and chromium from chemically-treated rubber. Users are advised to work in well-ventilated areas and use approved safety equipment, such as dust masks designed to filter microscopic particles, to reduce exposure to these chemicals.

Additional safety topics covered include the warning that the tool is not recommended for use in explosive atmospheres and that it, along with its accessories, must not be modified. Operators and maintenance personnel must be physically capable of handling the tool's bulk, weight, and power. The CP870 is intended for professional use only, underscoring its design for demanding industrial environments where adherence to safety protocols is paramount. The manual serves as a comprehensive guide, emphasizing that the user's care and good judgment are the best protection against injury, and that while not all possible hazards can be covered, the document highlights the most important ones to ensure safe and efficient operation.
