FEATURES KNOW YOUR CORNER CAT™ FINISH SANDER ORBITAL SANDING ACTION The oscillating action of your sander produces a very quick, small circular motion of the sanding pad. The motion is ideal for producing a fine finished grain or, when using the scrubbing pad, removing light rust, paint and other build up from the work surface. See Figure 1.
OPERATION NOTE: Batteries will not reach full charge the first time they are charged. Allow several cycles (operation followed by recharging) for them to become fully charged. WARNING: Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury. CHARGING A COOL BATTERY PACK If battery pack is within normal temperature range, the red LED on charger will come on.
OPERATION CHARGING A HOT BATTERY PACK When using the tool continuously, the batteries in the battery pack will become hot. You should let a hot battery pack cool down for approximately 30 minutes before attempting to recharge. When the battery pack becomes discharged and is hot, this will cause the green LED to come on instead of the red LED. After 30 minutes, reinsert the battery pack in the charger.
OPERATION WARNING: Battery tools are always in operating condition. Therefore, switch should always be locked when not in use or carrying at your side. SANDING SHEET AND PAD SELECTION Selecting the correct size grit and type sandpaper is an extremely important step in achieving a high quality sanded finish. Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding. Natural abrasives, such as flint and garnet, are too soft for economical use in power sanding.
OPERATION OPERATING THE SANDER See Figure 6 - 7. Secure the workpiece to prevent it from moving under the sander. WARNING: Unsecured workpieces could be thrown towards the operator, causing injury. WARNING: Keep your head away from the sander and the sanding area. Your hair could be drawn into the sander causing serious injury. Place the sander on the workpiece so that all of the sanding sheet surface is in contact with the workpiece.
OPERATION CHANGING SANDING SHEETS AND PADS HOOK-AND-LOOP PAD See Figure 8. The sander is packed with sanding sheets and scrubbing pads designed for a variety of uses. To change sheets and pads, simply pull the used sheet off the base and attach the desired sheet by pressing the sheet or pad onto the base of the sander. SANDING SHEET ROTATING THE SANDING SHEETS See Figure 9. The majority of wear in a precision sanding application occurs at the tip of the sanding sheet.
MAINTENANCE Only the parts listed in this manual are intended to be repaired or replaced by the customer. All other parts should be replaced at a Ryobi Authorized Service Center. WARNING: When servicing, use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product damage. CLEANING THE SCRUBBING PADS To ensure longer life and optimum performance, periodically clean all sanding residue and foreign materials from the scrubbing and polishing pads.
