SAFETY GUIDELINES - DEFINITIONS This manual contains information that is important for you to know and understand. This information relates to protecting YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the symbols to the right. Please read the manual and pay attention to these sections. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 12. USE THE RIGHT MACHINE. Don’t force a machine or an attachment to do a job for which it was not designed. Damage to the machine and/or injury may result. 13. USE RECOMMENDED ACCESSORIES. The use of accessories and attachments not recommended by Delta may cause damage to the machine or injury to the user. 14. USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
ADDITIONAL SAFETY RULES FOR LINE BORING MACHINES FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury. OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not thoroughly familiar with the operation of this machine. Knowledge is safety.
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 3prong grounding type plugs and matching receptacle which will accept the machine’s plug.
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 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. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct gauge to use depending on the cord length.

ALIGNING BORING BITS (For 32-325 Line Boring Machine Only) 1. Place a flat piece of wood (A) Fig. 37, on the table and against the fence as shown. Pull operating handle downward until ANY ONE boring bit (B) first contacts the top of the wood surface (A). NOTE: If all boring bits (B) contact the top surface of the wood at the same time, no alignment is necessary. 2. If any of the boring bits (B) Fig. 37, are not contacting the wood surface (A), remove each bit that does not contact the board one at a time.
CONNECTING AIR TO MACHINE (For 32-326 Pneumatic Line Boring Machine Only) A 1/4" female pipe thread (A) Fig. 43, is provided on the air filter for connecting the air line to the machine. An air supply of 90 psi is recommended for best results and this air supply must not exceed 125 psi. A Fig. 43 ADJUSTING AIR PRESSURE (For 32-326 Pneumatic Line Boring Machine Only) An air pressure gage (A) Fig. 44, and regulator (B) are supplied to regulate the air pressure used to operate the machine.
STARTING AND STOPPING MACHINE (For 32-326 Pneumatic Line Boring Machine Only) B A 1. Plug the motor cord (A) Fig. 46, into outlet (B) located on rear of the air and electric control box as shown. 2. Move the motor on-off switch (C) Fig. 47, to the “ON” position. The motor will not start at this time. MAKE SURE THE AREA UNDER THE HEAD IS FREE OF ALL OBSTACLES AND HANDS BEFORE PRECEDING TO THE NEXT STEP. Fig. 46 3. Press in and hold the start button (D) Fig. 47.
MULTI-POSITION LOWERING HANDLE B (For 32-325 Line Boring Machine Only) For extra leverage when boring holes, the handle (B) Fig. 50, can be pulled out as desired to increase leverage, as shown. To move the handle (B) out of the way when not in use, simply push in on handle. CONTROLLING DOWNWARD TRAVEL OF BORING HEAD Fig. 50 (For 32-325 Line Boring Machine Only) A stop is provided to set the depth of the boring bits above the table surface.
2. IMPORTANT: Before setting the limit switch depth setting, make certain all assembly instructions for PNEUMATIC LINE BORING MACHINES detailed in the instruction manual have been completed. Read and understand “STARTING AND STOPPING INSTRUCTIONS FOR PNEUMATIC LINE BORING MACHINES”, before continuing these instructions. C M L E Setting Limit Switch (Depth Control) 3. Place a test board (F) Fig. 54, long enough to reach both clamp cylinders (G), against the fence and under the boring bits as shown.
FENCE STOPS Two fence stops, one right (A) Fig. 58, and one left (B), are supplied with your boring machine. A scale (D) is provided on the fence which has a “0” mark in the center and extends 15 inches out to the left and right. The stops (A) and (B) can be moved anywhere along the fence by loosening lock handles (C), moving the stops (A) and (B), and tightening lock handles (C).
OPERATIONS LINE BORING 1. Figure 63 illustrates a typical line boring operation being performed on a workpiece. Note that the right end of the workpiece is positioned against the fence stop (A) and 13 holes are being bored with a 32mm center distance between each hole. A Fig. 63 2. If more than 13 holes are required, simply slide work-piece along the fence and push down on the indexing pin (B) Fig. 64, until the pointed end of the pin is in the last hole that was previously bored.
CORRECT OPERATING TECHNIQUE (For 32-326 Pneumatic Line Boring Machine Only) The following is a typical example of a line boring operation and how the electric/air controls function: 1. Place the workpiece (A) on the table and against the fence as shown in Fig. 66. A Fig. 66 B 2. Depress and hold the start button (B) Fig. 67. As soon as the start button (B) has been depressed, the two air clamps (C) will activate and the air clamp plungers (C) will lower, holding the workpiece firmly against the table.
