ADDITIONAL SPECIFIC SAFETY RULES FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. CLEAN THE MACHINE thoroughly when processing different types of workpieces (wood, steel, or aluminum). Combining wood and metal dust can create an explosion or fire hazard. DO NOT GRIND OR POLISH MAGNESIUM. Fire will result. 17. NEVER GRIND NEAR FLAMMABLE GAS OR LIQUIDS. Sparks can create a fire or an explosion. 18.
POWER CONNECTIONS A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the machine’s plug.
EXTENSION CORDS MINIMUM GAUGE EXTENSION CORD RECOMMENDED SIZES FOR USE WITH STATIONARY ELECTRIC MACHINES Ampere Rating Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine.
ASSEMBLY ASSEMBLY TOOLS REQUIRED Phillips Screwdriver Adjustable Wrench ASSEMBLY TIME ESTIMATE Approximately 30 Minutes ATTACHING AND ADJUSTING THE EYE SHIELD 1. 2. 3. Fasten the eye shield (A) Fig. 1 to the mounting bracket (B) using the two screws (C) and nuts (D). Use the knob screw and washer (G) Figs. 1 to attach the eye shield and the mounting bracket assembly (E) Fig. 3 to the side of the grinding wheel guard (F). The eye shield (A) Fig. 3 is adjustable.
A B B A Fig. 5 Fig. 4 E C E C E D D Fig. 7 Fig. 6 ADJUSTING THE SPARK DEFLECTOR As the five inch grinding wheel (H) Fig. 8, wears down due to extended use, the spark deflector (J) should be adjusted downward with it, so it is always set close to the grinding wheel for maximum operator safety. To adjust the spark deflector, loosen the screw (K) Fig. 8, position the spark deflector (J) close to the surface of the grinding wheel, and retighten the screw (K).
OPERATION OPERATIONAL CONTROLS AND ADJUSTMENTS STARTING AND STOPPING THE MACHINE 1. 2. The on/off switch (A) Fig. 11 is located on the front of the grinder. To turn the machine “ON”, move the switch up to the “ON” position. To turn the machine “OFF”, move the switch (A) down to the “OFF” position. A Make sure that the switch is in the “OFF” position before plugging in the power cord. In the event of a power failure, move the switch to the “OFF” position. An accidental start-up can cause injury.
CHANGING THE GRINDING WHEELS When changing the 5” grinding wheel, remove the eye shield, tool rest and side cover. Loosen and remove the arbor nut (A) Fig. 15 by turning it toward you (counterclockwise). To prevent shaft rotation, hold the grinding wheel by hand. A IMPORTANT: Do not overtighten the arbor nut (A) when you install a new wheel. Fig. 15 To change the 10” grinding wheel, remove the screws (A) Fig. 16. Lift the complete motor assembly (A) Fig. 17 from the base (B).
10" WET GRINDING WHEEL The 10" aluminum oxide grinding wheel operates at a slow speed of 70 RPM. This speed is suitable for honing garden tools, or sharpening chisels, and axes (Fig. 21). During operation, keep the water level in the reservoir (A) Fig. 26 at a 1" depth. This level will keep the wheel constantly wet and keep hardened tools cool without damaging their temper. The large wheel also is used to remove burrs from tools requiring keen edges. Fig.
MAINTENANCE LUBRICATION Periodically, lubricate the arbor shaft with light machine oil, through the oiler (A) Fig. 23. A To lubricate the worm gears, remove the nameplate (C) and apply grease to the two gears (A) and (B) Fig. 24. B A C A Fig. 23 Fig. 24 KEEP MACHINE CLEAN LUBRICATION Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts.
