Resumen del manual
Following this rule will reduce the risk of serious personal injury. The key to efficient operation begins by controlling the pressure and surface contact between the grinding wheel and workpiece. Flat surfaces are ground at an acute angle, normally between 5 to 15 degrees. For maximum control, hold the grinder in front and away from you with both hands, keeping the grinding wheel clear of the Fig. 8 TRIGGER SWITCH LOCK-ON BUTTON 5° TO 15° Fig. 7 workpiece. Start your grinder and let the motor and grinding wheel build up to full speed. Gradually lower grinder until the grinding wheel contacts the workpiece. For best results keep the grinder tilted at an angle from 5 to 15 degrees and continuously moving at a steady, consistent pace. Move the grinder back and forth or up and down over the work area. Keep the grinder moving so that an excessive amount of material is not removed from one area. If the grinder is held in one spot too long, it will gouge and cut grooves in the workpiece. If the grinder is held at too sharp an angle, it will also gouge the workpiece because of concentration of pressure on a small area. Use just enough pressure to keep the grinder from chattering or bouncing. Heavy pressure will decrease its speed and put a strain on the motor. Normally the weight of the tool alone is adequate for most grinding jobs. Use light pressure when grinding jagged edges or loose bolts where there is the potential for the grinder to snag on the metal edge. Lift the grinder away from the workpiece before turning your grinder off. Page 10 MAINTENANCE MAINTENANCE WARNING: When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product damage. GUARD REPLACEMENT See Figure 9. After extended use, the guard may become worn and need adjustments or replacing. If you drop your grinder and damage the guard it may also be necessary for you to replace it. PROCEED AS FOLLOWS WHEN REPLACEMENT IS REQUIRED: ¦ UNPLUG YOUR GRINDER. WARNING: Failure to unplug your grinder could result in accidental starting causing serious injury. ¦ Remove and reassemble parts as shown in figure 9. ¦ Depress spindle lock button and rotate clamp nut until spindle locks. ¦ Using the wrench provided, loosen and remove clamp nut from spindle. ¦ Remove grinding wheel and disc flange. ¦ Using a screwdriver, loosen the clamp screw until the guard can be adjusted or removed. ¦ If you are making adjustments, rotate the guard to its correct position as shown in figures 4, 5, and 9, then retighten clamp screw securely.Never use your grinder without the guard in place and properly adjusted. See Figures 4 and 5. ¦ If you are replacing the guard, loosen the clamp screw until the guard and clamp can be removed from the bearing cap. ¦ Place the new guard and clamp on the shoulder of the bearing cap. See Figure 9. NOTE: If the new guard and clamp will not fit, loosen the clamp screw until they slide over the bearing cap. ¦ Rotate guard to the correct position as shown in figure 9. ¦ Tighten clamp screw securely. ¦ Reassemble disc flange, grinding wheel, and clamp nut. Refer to "INSTALLING THE GRINDING WHEEL" instructions on page 8. ¦ Securely tighten the clamp nut with the wrench provided.

Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc. WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. WARNING: LUBRICATION Do not at any time let brake fluids, gasoline, petroleum- All of the bearings in this tool are lubricated with a sufficient based products, penetrating oils, etc. come in contact amount of high grade lubricant for the life of the unit under with plastic parts. They contain chemicals that can normal operating conditions. Therefore, no further lubrication damage, weaken, or destroy plastic. is required. DOUBLE INSULATION Double insulation is a concept in safety, in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. WARNING: The double insulated system is intended to protect the user from shock resulting from a break in the tool's internal wiring. Observe all normal safety precautions related to avoiding electrical shock. IMPORTANT Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service we suggest you return the tool to your nearest RYOBI A...
