    PRO 100 4.2. Installing and removing the arbor, MT3 twist drill bit, or tap chuck Unplug the power cord and lift the chip guard (1). Turn the handles to the right (2) to lift the motor. Use petroleum ether to clean the spindle and the arbor (drill bit,). Then, clean them with a dry cloth.
  • Page 12 PRO 100 To remove the arbor (drill bit), continue as follows. If the arbor has a nut (1), remove the nut. Next, lift the motor and turn the spindle (2) to align the holes in the spindle and gearbox (3). Put the drift into the hole (4). Next, hold the carrying handle with one hand and hit the drift with a mallet (5).

    PRO 100 4.3. Installing and removing the annular cutter Install the arbor as described before. Use gloves to put the correct pilot pin into the annular cutter (1). Use a dry cloth to clean the arbor and the cutter. Put the cutter into the arbor (2) to align the flat surfaces (3) with the screws (4).

    PRO 100 4.4. Installing and removing the cooling system Attach the bottle to the bracket (1). Put the hose with the spring (2) between the stop rod and the body (3). Then, attach the hose to the fitting and move the spring to the arbor (4, 5).

  • Page 15: Monitoring System Of The Clamping Force

    PRO 100 4.5. Monitoring system of the magnetic clamping force The drilling machine has a system that monitors the clamping force of the electro- magnetic base. The force will be lower if there is rust, paint, chips, or dirt. The force will be lower also if the surface is thin, rough, not flat, not rigid, the voltage is lower than required, or the bottom of the base is worn.
  • Page 16 PRO 100 Use the safety strap to prevent fall and injury if the machine loses the clamping. Attach the machine to a stable structure by putting the strap through the hole in the machine body. In the horizontal position, attach the strap to the carrying handle. Make sure that the strap is tight and not twisted.

    PRO 100 4.7. Drilling Set the speed based on the table that follows. Maximum hole diameter Rotational speed* Tool [mm] [in] [rpm] 3 5/32 100 (gear I) 2 3/64 175 (gear II) HSS annular cutter 1 19/64 275 (gear III) 45/64 500 (gear IV) 100 (gear I)
  • Page 18 PRO 100 Turn the gear switch as shown in the figure until you feel resistance. Incorrect setting can damage the gearbox. ✓ CORRECT INCORRECT ✗ Rotation direction Rotation direction Steel of strength of R ≥ 500 N/mm (70,000 psi), such as St5 (E295), 18G2A (S355N), or 45 (C45), requires lower speeds.
  • Page 19 PRO 100 When you use an annular cutter, drill only through holes. For incomplete through holes do not use the pilot pin. Incomplete through holes Complete through holes Keep the machine in the same position until the hole is made. When you use a drill bit, drill holes with diameters of 20-31.75 mm (25/32-1 1/4″) in two steps.
