OPERATION EXTENSION CORDS • The use of any extension cord will cause some drop in voltage and loss of power. • Wires of the extension cord must be of sufficient size to carry the current and maintain adequate voltage. • Use the table to determine the minimum wire size (A.W.G.) extension cord. • Use only 3-wire extension cords having 3-prong grounding type plugs and 3-pole receptacles which accept the tool plug. • If the extension cord is worn, cut, or damaged in any way, replace it immediately. Extension Cord Length Wire Size A.W.G. Up to 25 ft 18 25 to 50 ft 16 NOTE: Using extension cords over 50 ft. long is not recommended. MOTOR The sander is assembled with motor and wiring installed. The electrical wiring schematic is shown in Figure 8. MOTOR SPECIFICATIONS: Horsepower (Continuous Duty 1/4 Voltage 120 Amp 2.6 Hertz 60 Phase Single RPM 1725 ELECTRICAL CONNECTIONS WARNING: All electrical connections must be performed by a qualified electrician. Make sure tool is off and disconnected from power source while motor is mounted, connected, reconnected or anytime wiring is inspected. Motor and wires are installed as shown in wiring schematic (See Figure 8). Motor is assembled with approved, 3-conductor cord to be used at 120 volts. Switch Line Cord Figure 8 - Wiring Schematic Motor The power lines are inserted directly onto the switch. The green ground line must remain securely fastened to the frame to properly protect against electrical shock. The power supply to the motor is controlled by a single pole locking rocker switch. • Remove the key to prevent unauthorized use. OPERATION Refer to Figures 9 and 10.

Always wear safety goggles complying with United States ANSI Z87.1 (shown on package) before commencing power tool operation. Safety goggles are available at Sears retail stores or catalog. CAUTION: Always observe following safety precautions. SAFETY PRECAUTIONS • Whenever adjusting or replacing any parts on the tool, turn switch OFF and remove the plug from power source. • Make sure all guards are properly attached. All guards should be securely fastened. • Make sure all moving parts are free and clear of any interference. • Make sure all fasteners are tight and have not vibrated loose. • With power disconnected, test operation by hand for clear- ance and adjust if necessary. • Always wear eye protection or face shield. • After turning switch on, always allow drum to come up to full speed before sanding. • Be sure drum turns clockwise. • Avoid kickback by sanding in accordance with the direction- al arrows. • Keep your hands clear of abrasive sleeve and drum. • For optimum performance, do not stall motor or reduce speed. Do not force the work into the abrasive. • Always support workpiece with table. • Never push a sharp corner of the workpiece rapidly against sleeve. Abrasive backing may tear. • Replace abrasives when they become loaded (glazed) or frayed. • Never use machine for wet sanding which can create hazard of electrical shock. ON/OFF SWITCH Refer to Figure 9, page 6. The ON/OFF switch is located on the upper front right of the base. To turn the sander ON, pull the switch to the up position.
