SAFETY RULES Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result.
ADDITIONAL SAFETY RULES FOR GRINDERS 1. DO NOT operate your tool until it is completely assembled and installed according to the instructions. 15. MAKE CERTAIN the blotter and wheel flanges furnished are used to mount the grinding wheels onto the grinder shaft. 2. IF YOU ARE NOT thoroughly familiar with the operation of grinders, obtain advice from your supervisor, instructor or other qualified person. 16. THE USE of attachments and accessories not recommended by Delta may result in the risk of injuries.
UNPACKING AND CLEANING Carefully unpack the tool and all loose items from the carton. Remove the protective coating from all unpainted parts. This coating may be removed with a soft cloth moistened with kerosene (do not use acetone, gasoline, or lacquer thinner for this purpose). Fig. 1 illustrates the components of the grinder. WARNING: FOR YOUR OWN SAFETY, DO NOT CONNECT THE TOOL TO THE POWER SOURCE UNTIL THE MACHINE IS COMPLETELY ASSEMBLED AND YOU HAVE READ AND UNDERSTAND THE ENTIRE INSTRUCTION MANUAL.

ASSEMBLING PEDESTAL (MODELS 23-730 & 23-735) NOTE: Pedestal hardware is illustrated ACTUAL SIZE Fig. 10. 1. Stand the column up with the square end on the floor Fig. 11. 2. Place the base on top of the round end of the column, and line up bolt holes Fig. 12. 3. Insert bolt (11) and washer (12) Fig. 10, through the round end of the column and then thread the screw through the base plate. 4. Once all four screws are threaded into the base plate Fig. 12, place one washer (13) Fig. 10, one nut (14) Fig.
EXTENSION CORDS 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 a 3-pole receptacle which will accept the tool’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the saw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. 14, shows the correct gauge to use depending on the cord length.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts: GROUNDED OUTLET BOX CURRENT CARRYING PRONGS This tool is intended for use on a normal 120-volt circuit and has a grounded plug that looks like the plug illustrated in Fig. 15. If a properly grounded outlet is not available, a temporary adapter, shown in Fig. 16, may be used for connecting the 3-prong grounding type plug to a 2-pole receptacle.
STARTING AND STOPPING GRINDER The “ON-OFF” switch (A) Fig. 18 is located on the front of the grinder. To turn the grinder “ON” move the switch to the right, and to turn the grinder “OFF” move the switch to the left. A GRINDING WHEELS WARNING: THE USE OF ACCESSORIES AND ATTACHMENTS NOT RECOMMENDED BY DELTA MAY RESULT IN RISK OF INJURIES. Grinding wheels used with Model 23-730 grinders should be rated for 3600 RPM or higher and be 8" in diameter with a 5/8" or 1" arbor hole.
CHANGING GRINDING WHEELS A CAUTION: DISCONNECT MACHINE FROM POWER SOURCE BEFORE CHANGING GRINDING WHEELS. 1. When changing wheels, remove the three screws (A) Fig. 20, attaching the side covers to the grinder and remove the side cover (B). 2. To prevent shaft rotation, place a wedge between the grinding wheel (C) Fig. 21, and the tool rest (D). NOTE: Facing the front of the grinder: to replace the wheel on the left side of the grinder, turn the arbor nut (E) Fig.
OPERATIONS IMPORTANT: KEEP SPARK GUARDS AND EYE SHIELDS IN PLACE AT ALL TIMES. Figures 23, 24, and 25, illustrate several typical operations that can be accomplished using the grinder. Each tool rest should be positioned a little below the center of the grinding wheel and adjusted so the edge of the tool rest is as close as possible to the grinding wheel for maximum support to the piece that is being ground. This is the most practical and safest position for general work.
