The disc holder (A) slides neatly into the pocket of the sander as shown in Fig. 17. A A Fig. 16 Fig. 17 FASTENING S A N D E R TO A SUPPORTING S U R FA C E If during operation there is any tendency for the sander to tip over, slide or walk, the sander must be secured to the supporting surface using the four holes in the base of the machine.
GROUNDING INSTRUCTIONS CAUTION: THIS TO O L MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
O P E R ATING CONTROLS AND ADJUSTMENTS STARTING A N D STOPPING SANDER The on/off switch (A) Fig. 21, is located on the sander base. To turn the sander ON move the switch to the up position. To turn the sander OFF move the switch to the down position. A Fig. 21 LOCKING SWITCH IN THE OFF POSITION W e suggest that when the sander is not in use, the switch be locked in the OFF position. This can be done by grasping the switch toggle (B) and pulling it out of the switch, as shown in Fig. 22.
O P E R ATIONS PLEASE READ THE SAFETY RULES BEFORE OPERATING THE SANDER. The random orbital sander can be used with or without the fence depending on the application; however, we recommend that the fence be used whenever possible. Fig. 25, illustrates a typical edge sanding operation using the fence as a backstop. Fig. 26, illustrates a typical flat sanding operation using the fence as a guide. Fig. 27, illustrates a typical flat sanding operation without the fence. Fig. 25 Fig. 26 Fig.
