Alpha® VSP-320 / VSP-340 Variable Speed Wet PolisherThe Alpha® VSP-320 (120V) and VSP-340 (230V) replace the legacy VSP-120 with a major overhaul that includes a heavy-duty gear system with step-down transmission, precision-machined parts to minimize noise and vibration, and a specially coated spindle that reduces friction between oil seals. A flexible kink-free water hose, inline GFCI on the power cord, EasyOn-EasyOff sleeve and an exclusive adjustable splash guard with ventilation cap keep water out of the motor housing and make the tool comfortable to handle all day. Variable speed of 700-2,500 RPM covers the full polishing range for granite, marble and engineered stone.Features Variable Speed 700-2,500 RPM Heavy-Duty Gear System with Step-Down Transmission Powerful 7 Amp Motor (800W) 15 ft Flexible All-Weather Water Hose with Garden Hose Adapter 15 ft Electrical Power Cord with Inline GFCI EasyOn-EasyOff Sleeve for improved maneuverability Adjustable Splash Guard with Clamp Center Water-Feed System Ventilation Cap diverts water from motor housing C-Handle and reversible Side Handle included One-Year Tool Warranty .dst-accordion { margin-top: 25px; border: 1px solid #FDDCC5; border-radius: 6px; overflow: hidden; } .dst-accordion-item { border-bottom: 1px solid #FDDCC5; } .dst-accordion-item:last-child { border-bottom: none; } .dst-accordion-toggle { display: none; } .dst-accordion-label { display: flex; justify-content: space-between; align-items: center; padding: 14px 20px; cursor: pointer; font-size: 17px; font-weight: 700; color: #231F20; background: #fff; transition: background 0.2s; } .dst-accordion-label:hover { background: #FFF3EB; } .dst-accordion-label::after { content: '+'; font-size: 22px; font-weight: 700; color: #F15C22; transition: transform 0.3s; } .dst-accordion-toggle:checked + .dst-accordion-label { background: #FFF3EB; } .dst-accordion-toggle:checked + .dst-accordion-label::after { content: '\2212'; } .dst-accordion-content { max-height: 0; overflow: hidden; transition: max-height 0.4s ease; padding: 0 20px; background: #fff; } .dst-accordion-toggle:checked ~ .dst-accordion-content { max-height: 5000px; padding: 15px 20px 20px; } Models / Part Numbers Part No. Voltage Amperage Speed Range Spindle UPC VSP-320 120V 7.0A 700-2,500 RPM 5/8"-11 749173541032 VSP-340 230V 7.0A 700-2,500 RPM 5/8"-11 749173541049 How to Use Verify your supply voltage matches the model — VSP-320 for 120V or VSP-340 for 230V. Thread a 5/8"-11 polishing pad, backer pad or polishing disc onto the spindle. Connect the 15 ft flexible hose to a garden hose source using the included adapter; open the in-line valve to start water flow. Plug in to a grounded outlet and confirm the inline GFCI is operational before each use. Install the C-Handle or reversible Side Handle for the most comfortable grip and best control. Start at the lowest speed and dial up gradually within the 700-2,500 RPM range to match the abrasive grit. Keep the pad flat against the work; let the tool do the work — do not bear down. After use, run the spindle briefly to evacuate water and blow-dry the housing with compressed air when available.

When compressed air is available, blow-dry the inside of the motor housing and clear dust from moving parts.Where can I send the polisher for repair?You can order spare parts for in-house service, take the tool to a local Alpha dealer, or send it directly to Alpha for factory repair.What is the difference between the VSP-320 and the VSP-340?The VSP-320 is the 120V North American version (Type A plug); the VSP-340 is the 230V international version (CEE plug). All other specifications are identical.
