15 PRECAUTIONS ON USING AUTOMATIC MAGNETIC DRILL PRESS. Do not use the machine for drilling non-magnetic materials. As the magnetic drill press drills the workpiece by attracting it with as electromagnet, it is not applicable for drilling non-magnetic materials (aluminum, copper alloy, etc.) which is not attracted by the electromagnet.. Take special care in handling the electromagnet attracting surface. If the attracting surface is rusted or has a flaw or dent, it weakens the attracting force of the electromagnet. Periodically check whether there are any scratches, etc., on the attracting surface. 3. Fasten the chain with the body. This machine is intended for operation on the floor. Do not use it in the ceiling, on a wall or an oblique surface. Always use the chain available as optional accessory while drilling in high places. Fasten the machine to a suitable place in the work area to protect it from falling or moving. 4. Make sure that the electromagnet is not raised. In order to prevent the electromagnet from rising during work, make sure that its whole attracting surface contacts the workpiece and that the body is firmly fastened to the workpiece (for instance by pulling the top of the drill sideways). 5. When opening holes in the thin plate, make sure to use a auxiliary plate. If the workpiece thickness is too small, the attracting force of the electromagnet is weakened, causing failure of drilling. In such cases, use an auxiliary iron plate to strengthen the attracting force. 6. Pay attention to areas below the work site when operating at high places. When the machine is used at high places, make sure there is nobody below before starting operation. 7. Check the mains socket. If the power cord plug is disconnected from the mains socket during operation, the electromagnet does not work, causing a hazard. Check if the power cord plug is loose and liable to easy disconnection when it is connected to a main socket. 8. Do not use this machine with an engine-powered generator or DC power supply. Connecting this machine to an engine-powered generator can damage the electronic circuits. Do not use it with a DC power supply either. Such usage not only can damage the product, but is also dangerous. 9. Do not wear gloves during operation. Avoid wearing gloves during operation of the machine, because there is a possibility that the gloves may get caught in the machine. 0. Wear safety shoes during operation. As there is a good deal of heavy material handling during operation, wear safety shoes to protect your feet.. During automatic operation, there must be no obstructions within the movement range. During automatic operation, there must be no obstructions within the range through which the drill moves up and down or within the range through which the handle rotates.. Never touch rotating parts. Keep your hand and body well away from the rotating drill or swarf to avoid injury. The drill is hot after drilling. Avoid touching it directly when replacing it. 3. Eliminate the play of the sliding part. Play in the sliding parts of the electric drill will shorten the service life of the steel core bit considerably. Adjust the play in the sliding part so the drill does not drop from its own weight when the feed handle is set to manual. Refer to the section Maintenance and Inspection for a description of the adjustment procedures. 4. Supply cutting lubricant when using the steel core bit. Be sure to supply cutting lubricant when using the steel core bit. Otherwise, the blade edge life is greatly reduced. 5. When the electromagnet floats away from the work during operation. Turn the feed handle inversely to eliminate the thrust applied to the drill. If the electromagnet floats away, the attracting force is greatly weakened and it is dangerous to continue operation. 6. Do not stop rotation halfway when manual drilling. If the machine is stopped or locked halfway when manual drilling, the steel core bit blade edge may be damaged. Before stopping the machine, turn the feed handle inversely and withdraw the steel core bit from the material. 7. Pay attention to flying of the cut core (cylindrical cut chip). Pay attention to flying of the cutting core at the end of drilling with the steel core bit. Particularly, in operation at high places, take care to prevent the falling of the cutting core presenting a hazard. As the cutting core is heated, do not touch it directly with bare hands. 8. Be careful of welding machines. If you work right next to a welding machine, the rotation or feed may be unstable. 9. Store the machine in a dry place. If the machine is stored in a humid place, the electromagnet may become rusted, reducing the attracting force. The electric insulation may also be impaired, presenting the possibility of electric shock. 4

Firmly secure the two steel plates. 5 Drilling various types of steel plates Drilling various types of shape steels PREPARATION BEFORE OPERATION. Grounding. This tool should be grounded while in use to protect the operator from electric shock. The tool is equipped with a three-conductor cord and grounding type plug to fit the proper grounding type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never connect the green (or green and yellow) wire to a live terminal.

17 . Extension cord. When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable. CAUTION: Damaged cord must be replaced or repaired. 3. Transporting of the machine. CAUTION: When transporting this machine, set the feed handle to automatic (as explained in ltem 7 of Usage on Page 9) and fasten so that the electric drill does not move. (Fig. ) () When moving the machine -m in places with secure foothold, it is convenient to use the grip handle. () When moving the machine a longer distance or moving it at places with insecure foothold, two persons are needed to hold the grip handle and electric drill switch handle. Carry the machine carefully. NOTE: Do not pull the cord coming from the electric drill. Code Side handle Grip handle Fig. Feed handle Side handle 4. Clean the attracting surface of the electromagnet. If the attracting surface of the electromagnet is rusted or stained by foreign matter, the attracting force of the electromagnet is weakened. The attracting surface should be kept clean. 5. Keep the chain ready to hand. If the electromagnet floats away from the attracting surface due to a thrust, the attracting force is greatly weakened and the electromagnet does not work at power failure. Therefore, if there is a possibility of the machine moving or falling during operation at the side of the workpiece or above your head, for example, the machine must be firmly secured to the workpiece beforehand. Keep the chain (optional accessory) ready at hand to secure the machine in such cases. For how to use the chain, refer to HOW TO USE, 9. When there is a possibility of the machine body moving. PRIOR TO USE. Power source. Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate. CAUTION: Connecting this machine to an engine-powered generator can damage the electronic circuits. Do not use it with a DC power supply either. Such usage not only can damage the product, but is also dangerous. If the voltage of the power supply used is lower than that on the nameplate, the electromagnetic attractive force drops and the electromagnet may float away from the work.. Power switch. Ensure that the power switch is in the [OFF] position. If the plug is connected to a power receptacle while the power switch is in the drill switch [ON] position, the power tool will start operating immediately, inviting serious accident. 3. Attaching the center pin and steel core bit. This machine has two of the springs marked * in the figure (Fig. 3) (one black and one yellow). Use them as follows according to the plate thickness. Spring color Application Can be used with thin plates and Black plates up to a maximum thickness of 50mm. For thin plates: use this spring when Yellow the cutting core jams easily with the black spring. CAUTION: Do not use the yellow spring for drilling plates thicker than 0mm. The spring or the center pin may break. Use the following procedure to install the center pin and steel core bit. () Pass the center pin through the center pin guide, insert the spring and the thrust washer and install in the threaded section of the spindle. (Fig. 3) After installation, tighten securely with two of the supplied wrenches (3 and 7mm). NOTE Do not forget to install the thrust washer. The center pin guide may be difficult to remove. () Install the steel core bit in the center pin guide and tighten securely with two of the supplied wrenches ( and 7mm). *Spring Thrust washer Spindle Center pin guide Center pin Fig. 3 6

18 4. Fill the tank with cutting solution. Dilute the special cutting solution that is a standard accessory with 0 parts tap water. Remove the tank cap and pour in the cutting solution without spilling it. CAUTION: When pouring in the cutting solution, be careful to keep any cutting solution from getting on switch sections or motor sections of this machine. The cutting solution can freeze in cold weather. Use only the special cutting solution made for this machine. Do not dilute the cutting solution with well water. Well water can cause rusting in the spindle or allow adhesion of impurities and block the flow of the cutting solution. 5. Check the mains socket. If the mains socket is too loose or the plug is liable to easy disconnection from the socket, repair is necessary. Consult your nearest electric shop. If the machine is operated without repairing the mains socket, the machine may become overheated, presenting a hazard. If the power cord plug is disconnected during operation, the electromagnet does not work and this is very dangerous. 6. Check that there is no play in sliding sections. If there is any play in the column and electric drill sliding sections, the lifespan of the steel core bit is drastically reduced. If the electric drill falls freely with the feed handle set to manual, the play has increased, so adjust the play before using. This adjustment is explained in Maintenance and Inspections on Page. DISPLAY LAMPS The display lamps change as in the table below according to switch lever operation, the feed handle Manual Feed/Automatic Feed setting, the load, and the power supply voltage.

21 [Steel core bit drilling operation] Center pin Cutting core. Align the center pin with the punch position.. Starts drilling while supplying cutting solution. If the center pin is pushed up, supply of lubricant will start automatically. Fig The cutting core pops out simultaneously with completion of drilling. The center pin drops and supply of lubricant stops automatically. NOTE Cut in manually -3mm, then before putting the drill into automatic, stop the feed for - seconds and allow the electric drill to idle. If you put the drill into automatic with a load still on it, the drilling may speed up excessively or the electric drill may either rise up midway through the drilling or fail to rise up after the drilling. When using the steel core bit, always cool the tip with cutting solution. If you do not cool the steel core bit, the life of the tip is reduced. That is why this machine should not be used on ceilings or walls, in which usage the cutting solution would not reach the steel core bit tip. If the electric drill is outside the range indicated by the arrow on the automatic feed range label and you set the feed handle to Automatic Feed, the feed stops after a few seconds. If that happens, switch off the Drill switch [ON], return the feed handle to Manual Feed and move the electric drill into the automatic feed range. Never switch the gear change lever during the drill operation. This may damage the changing part. Watch out for the cutting core flying out when the drilling is complete. In particular, when working in high places, watch out for the cutting core dropping. Immediately after completing drilling, the electric drill rises and the feed handle turns rapidly, so be careful the rapidly turning handle does not strike your hands. When adjusting the cock lever for automatic drilling, watch out for the feed handle. In particular, do not adjust the cock lever from immediately after the end of drilling until the electric drill stops. The steel core will become clogged excessively if there are repeated overloads while drilling holes and may be difficult to remove. If this occurs, use a long handle wrench or other similar device to remove. After each hole drilled, remove the cutting core and the cutting power. If cutting power remains in the steel core bit, remove it before drilling the next hole. If the cutting core is jammed in the steel core bit, remove it by knocking gently on the flange of the cutting core with a thin rod or the like. You can not drill two steel plates at once with this steel core. To drill two steel plates at once, use the multi-cutting steel core, sold separately. 0

22 9. When there is a possibility of the machine body falling. When there is a possibility of the machine body falling due to power failure or floated electromagnet in operation at high places be sure to secure the machine body to the workpiece with the chain available as optional accessory. (Fig. 5) Use the chain as follows. () Activate the electromagnet. () Wind the chain round the workpiece. (3) Connect the chain and the machine body securely with the shackle attached to the chain. Chain Shackle Tighten the screw fully ABNORMAL SYMPTOMS Detailed view of joint Fig. 5 This machine is microcomputer controlled. It is designed to stop in the unlikely event that the microcomputer malfunctions due to power line noise or any other cause. If any of the following symptoms occur during use, it does not indicate a break down. Return the switch lever to the Magnet ON position, return the feed handle to Manual Feed, implement the appropriate solution, then carry out the next drilling operation. Symptom Cause Solution With the switch lever in the Drill ON position, when the feed handle was moved to Automatic Feed, the electric drill stopped. During drilling, the electric drill rate of rotation fluctuates greatly and the drill groans or the electric drill stops and the overload lamp blinks. The electric drill is outside the automatic feed range. The power supply voltage is too low. The power supply voltage is too low due to voltage drop across the extension cord. The flow of cutting solution is insufficient. The tip of the steel core bit is dull. The drill speed is too fast. Move the electric drill to within the automatic feed range. Change the power supply. Stop using extension cord or use thicker ones. Increase the flow of cutting solution or remove jams midway. Regrind the tip or replace it. Set the gear change lever from HIGH to LOW. Otherwise set the speed change switch from high speed to low speed. Midway through drilling, the electric drill rises and stops. After drilling is complete, the electric drill stops without rising. Microcomputer malfunction. While drilling with manual feed, the switch was set to Auto. Microcomputer malfunction. The feed handle was set to automatic feed while drilling with manual feed. Microcomputer malfunction. Repeat the drilling operation. Do not switch to Auto while there is a load on the electric drill. Repeat the drilling operation. Do not switch the feed handle to automatic feed with a load on the electric drill. Repeat the drilling operation.

23 MAINTENANCE AND INSPECTION CAUTION: Be sure to switch power OFF and disconnect the attachment plug from the power receptacle to avoid serious trouble.. Check the electromagnet. If the electromagnet bottom is flawed or rusted, the attracting force is weakened. Before operation, check the bottom for any flaw or rust. When the machine is not in use, turn off the power switch, disconnect the power cord plug from the mains socket and store the machine in a dry place.. Adjust the play of the sliding part. (Fig. 6) If there is play in the electric drill sliding part, the steel core bit life will be greatly reduced. If there is play, adjust it as follows. () Set the switch lever to the Magnet ON position to fasten to the steel plate with the electromagnet. () Set the feed handle to the manual feed position. While turning the feed handle and gently tighten the four M8 nylock screws with the supplied hexagon bar wrench. Tighten enough that the electric drill does not fall due to its own weight. (3) If the movement feels too hard or too easy, the adjustment is insufficient, so loosen the four screws and tighten them again evenly. M8 Nylock set screw Hexagon bar wrench Electric drill Nut M0 Lock lever Fig Check the steel core bit. If the machine is continuously operated with a dull steel core bit, the motor is overloaded, decreasing operation efficiency. Re-grind or replace the steel core bit as soon as possible. <Replacement of the steel core bit> The steel core bit is attached by winding it clockwise around the spindle. When replacing, use the two accessory wrenches ( and 7mm) to remove.
