The Radley 5" Random Orbit Sander, model 1262-171, is a corded power tool designed for sanding various surfaces. It operates on a 120V, 60Hz AC power supply with a 2.0 Amp motor, delivering a no-load speed of 12,000 OPM (Oscillations Per Minute). The sander is equipped with a 5-inch disc diameter and weighs 3 lb. 6 oz (1.53 kg), making it a relatively lightweight and manageable tool for a range of sanding tasks.
Function Description:
The Radley Random Orbit Sander is intended for general sanding applications, providing a smooth finish on various materials. Its random orbital motion helps prevent swirl marks and ensures an even sanding pattern. The tool is designed for use with 5-inch sanding discs that feature an 8-hole pattern and a hook & loop backing system for easy attachment and removal. It includes a dust bag assembly for collecting sanding dust, contributing to a cleaner work environment and improved visibility of the workpiece.

Usage Features:
The sander is designed with user convenience and safety in mind.
- ON/OFF Switch: A clearly marked ON/OFF switch allows for easy control of the tool. The switch is operated by pressing the left side for ON and the right side for OFF.
- Palm Grip: The tool features a palm grip design, allowing for comfortable one-handed operation. Users are cautioned not to cover the motor's cooling vents with their hands during use to prevent overheating.
- Sanding Disc Installation: Sanding discs are easily attached by firmly pressing them onto the hook & loop pad, ensuring the 8 holes on the disc align with the matching holes on the sanding base. Removal is achieved by simply peeling the disc away. The manual includes 3 x hook & loop sandpapers (60, 80, 120 grit) to get started.
- Dust Bag Assembly: The dust bag connects to a dust port at the rear of the sander. It is installed by sliding the connector into the port, ensuring a key on the connector mates with a keyway in the port, and then turning the bag approximately 15° clockwise to lock it in place.
- Sanding Technique: Users are advised to place the sander on the workpiece with the entire sanding disc surface in contact before turning it ON. The sander should be moved slowly over the workpiece in parallel lines, circles, or crosswise movements. The random orbital motion eliminates the need to sand with the grain. The sander should be turned OFF and allowed to come to a complete stop before being removed from the workpiece.
- Sanding Disc Selection: The manual emphasizes the importance of selecting the correct grit and type of sandpaper for the desired finish. Aluminum oxide, silicon carbide, and other synthetic abrasives are recommended for power sanding. Coarse grit removes more material, while fine grit produces the best finish. Users should start with coarse grit for rough surfaces, then progress to medium and fine grits until the surface is uniform. Higher numbers indicate finer grit, and lower numbers indicate coarser grit.
- Safety Precautions: The manual highlights several safety warnings, including the necessity of reading all instructions before use, wearing CSA approved eye protection (safety goggles, not glasses), ear protection, and a dust mask. It also warns against operating the tool in explosive atmospheres, exposing it to rain or wet conditions, and using it while tired or under the influence. Proper circuit protection and extension cord selection are also emphasized.
Maintenance Features:
Regular maintenance is crucial for the longevity and safe operation of the sander.
- Cleaning the Dust Bag: The dust bag should be cleaned frequently to maintain efficient dust collection. To clean, the dust bag assembly is removed by rotating it counterclockwise approximately 15° and pulling it out. The collected dust is then removed by shaking the bag with the end cap opening pointing downward.
- General Cleaning: Plastic parts should be cleaned with a clean cloth to remove dirt, dust, oil, and grease. Solvents, brake fluids, gasoline, petroleum-based products, and penetrating oils should not be used on plastic parts as they can cause damage.
- Motor Cooling: If the motor overheats during extended sanding, the sander should be turned OFF, allowed to cool, and checked to ensure cooling vents are not covered.
- Lubrication: All bearings in the tool are pre-lubricated with a high-grade lubricant for the life of the unit under normal conditions, so no further lubrication is required.
- Inspection: Before each use, verify that the sander cord is not damaged, the sanding disc is in good condition and properly installed, and the workpiece is secured and free from foreign objects.
- Repair: Any electrical repairs should be performed by a qualified technician. Only identical replacement parts should be used for servicing to avoid hazards and product damage. Modifying the tool or creating accessories is strongly discouraged as it voids the warranty and can lead to serious injury.
- Dust Exposure Warning: The manual specifically warns about dust created by power sanding, which may contain chemicals known to cause cancer or other abnormalities. Users are advised to work in a well-ventilated area and use approved safety equipment, such as a dust mask designed to filter microscopic particles. The use of the tool on fiberglass, wallboard, spackling compounds, or plaster is noted to cause accelerated wear, and frequent cleaning with an air jet is recommended if used on these materials.
Warranty:
The Radley Random Orbit Sander comes with a one-year warranty from the date of purchase, covering defects in material or workmanship. This warranty allows for exchange at any Home Hardware store with the original bill of sale. It explicitly excludes expendable parts like blades, brushes, belts, light bulbs, and batteries. The warranty does not cover normal wear and tear, abuse, misuse, or defects caused by careless or accidental mishandling. Commercial or rental use of the product also voids the warranty.
