Page 5: Before Use
Before use Rotec magnet drilling machines are specially designed for drilling holes is steel, possibly expanded by the possibility of tapping/reaming/countersinking (depending on model). Rotec magnetic drilling machines may not be adapted and/or used for applications other than those they were designed for, including driving other machines. Make sure that you can oversee the entire work areas from where you are operating this machine. Use barriers to keep others away. Do not use the machine in places subject to hazard of explosion‐ electrical tools produce sparks which may ignite flammable materials or gasses. To prevent electrical shocks, do not use the machine in moist or wet conditions or environments. Always operate this tool using both hands. Make sure the work piece is always clamped down safety. This magnetic drilling machine is equipped with a lead and plug approved for the country or region it is to be used in. The yellow‐green wire in the lead is the earth wire. Never connect this to a pole under voltage. All Rotec magnetic drilling machines are manufactured to use with AC current and not suitable to work on DC current. Make sure the magnetic drilling machine is connected to a stable power supply. Rotec do not recommend the use of a generator or other mobile power supply for power supply. Rotec does not recommend the use of extension cables. If there is no other way, use good quality cables and keep extension cables as short as possible.

Page 7: Cooling/Lubrication
2 Fixing screws of Morse Taper Rotec recommends the use of cooling and lubrication agents. Not only do these assist in drilling but they will also lengthen the lifespan of your tools. One of the advantages of the use of hole cutters is that cooling and lubrication agent scan be supplied from the inside, so that the agents end up in the right place. All magnetic drilling machines from Rotec can be equipped with a automatic cooling system which provides a guaranteed supply of the cooling and lubrication agents from the inside. If your machine is not be equipped with an automatic coolant system it will still be possible to cool from the inside. Use the holes in the Morse Taper (number 1 in picture) for this purpose by squirting the cooling and lubrication agent through them and fill the Morse Taper. NOTE : For vertical or upside‐down processing, Rotec recommends the use of a drilling compound or paste like 901.4045 or 901.4046. 4 ‐ Tool Assembly Morse Taper Assembly Mount the Morse Taper into your machine by push it firm into the shaft extending from the motor unit. Beware that the tip on top of the Morse Taper is in line with the shaft. To take the Morse Taper out use the Ejector Pin to force it out. Hole Cutter Assembly ... -
Page 8: Drill Chuck Assembly
Drill Chuck Assembly The option of making our machines suitable for the use of standard spiral drills and other tools by using a cylindrical shaft is an important characteristic of Rotec magnetic drilling machines. Please see the technical data for maximum capacity. Installation of 13mm Chuck by using adapter IBK.14 The 545.1021 is a adaptor from 1/2"x20 UNF to 19mm Weldon. Attach a Drill Chuck with internal 1/2"x20 UNF on the 545.1021 adaptor. To attach the assembly into your Spindle, follow the instructions (with exception of the Pilot Pin) for installation of a Hole Cutter. Adaptor IBK.14 can be used on most machines in our program. Installation of 13mm Chuck directly on the motor unit For the RTC.100/4 magnetic drilling machine it is possible to install a drill Chuck directly to the shaft extending from the motor unit. Attach to the drill chuck with article number 181.1005 a adaptor with article number 180.2016. This way the drill chuck can be mounted as a Morse Taper in your machine. 4 ‐ The Magnetic Drilling Machine The Magnetic base Material of minimum 10mm thickness is required for the magnet to work the best. The attachment force generated by the magnet depends on various factors. ‐ Thickness of the material the magnet is placed on ‐ Paint or coating of the material the magnet is placed on. ‐ Metal chips, oil or other dirt under the magnet. If the LED indicator lights up GREEN, the magnet is generating sufficient attachment force. If the LED indicator lights up RED, the magnet may not generating sufficient attachment force. We would like to point out that this is only an indication and not a certainly that the magnet will not release from the material. Rotec accepts no liability ensuring from the magnet indicator not functioning or functioning poorly. Make sure that the magnet attaches tightly to the work piece before turning on the motor unit of the ... -

2 ‐ The On/Off Switch: This switch is used to switch the motor unit On and Off and is included on every Rotec Magnetic Drilling Machine 3 ‐ The Fuse holder with Fuse: This Fuse holder is included on every Rotec Magnetic Drilling Machine and holds the fuse type : 5x20, F2A. 4 ‐ The Magnet LED Indicator: This LED indicator shows the generated magnetic force. 5 ‐ The L/R Switch: This switch controls the direction of the motor unit. The Electronic Controls On the side of the motor unit are the variable electronic control wheels. The blue wheel regulate the rotation speed and the red wheel regulate the torque power of the motor unit. When drilling with big diameter cutters or deep holes start drilling with the torque wheel in a low position to prevent cutter damage. Increase the power setting a bit when the machine stops too fast. When the machine stops cause of torque overload, press the 0 and then the I button of the On/Off switch to start drilling again. Continuous electronic Temperature protection : The RTC.100/4 is equipped with a all‐time electronic temperature protection. If the temperature of the motor unit reaches 70° Celsius, the motor unit will stop. After a few minutes it can be started again and we recommend to let the motor run unloaded with the electronic speed adjustment set on 100% to let the motor unit cool down. 4‐speed Manual Gearbox 9 ... - Page 10 The RTC.100/4 is equipped with a 4‐speed gearbox. The two gear switches makes it possible to choose 4 manual speeds. Also does the RTC.100/4 have a electronic speed adjustment so every wanted speed can be selected. Important is that the closest mechanical gear is selected first and after that the speed can be decreased by the electronic adjustment. Therefore, always try to keep the electronic speed wheel above 50% to prevent the armature to build up heat due low running speed. 600rpm: left switch up, right switch down For twist drills and hole cutters till 25mm 370rpm: left switch up, right switch up For hole cutters 25‐50mm 175rpm: left switch down, right switch down For hole cutters 50‐75mm 110rpm: left switch down, right switch up For hole cutters 75‐100mm and tapping. ("left" and "right" is seen from front of motor unit) Note that the mentioned cutter sizes is only a indication. Depending on variables as the condition of the used cutter, hardness of material or if oil is used the best drilling speed can be different as mentioned above. To select other gear, turn off motor unit and main power. Push the black switch on the side of the gearbox and slide to other position. A slight turn of the output shaft by hand while sliding the black switch to the other position can be necessary to line up the gears inside. Proof that the gear is locked if the black switch comes back to front. ...

7 Adjust the oil supply when necessary, if your drill does not have a auto coolant system, stop drilling regularly, refill the holes of the spindle and continue drilling. 8 Apply less pressure when the drill cuts through the material. 9 Turn the arms to put the motor in highest position and turn off the motor unit. 10 Remove the burr, metal chips and clean the cutter and surface without getting injuries. Caution : The metal piece drilled out can be sharp and very hot!! Tapping RTC.100/4 Drill the hole on the recommended size of the tap. Do not turn the magnet off to keep the machine on its position. Take the cutter out and use a tap collet to fix the tap to the machine. These adapters exist in several DIN and ISO norms and are based on the shaft diameter of the tap that is used. Use the low gear and low rpm for tapping. Stop the machine manually before the tap is completely through the hole. Select the Reverse (Left) and let the tap run back slowly but also support the run back by turning back the handles. Do not let your tap push back the motor unit by itself! If your tap have to make the whole way through the material, then remove the tap out of the collet when the hole is completely tapped. 11 ... -
