2.7. Tapping
With the entering tap (tap no. 1) installed, set the first gear. Next, rotate the spoke handles
to the left to place the tap above a hole with diameter appropriate for the tap used. If the
diameter of the hole is too small, tapping may be impossible due to excessive milling
resistance and insufficient motor power.
Spread tap oil on the cutting part of the screw tap to prevent seizure and extend
durability. Next, press the lever lock and set the ON/OFF lever to the lower position to start
the motor, and then slowly rotate the spoke handles to the left to bring the screw tap close to
the workpiece, and begin tapping. After tapping with the entering tap (tap no. 1) is finished,
press the lever lock and set the ON/OFF lever to the horizontal (‘0’) position to stop the motor,
and then set the ON/OFF lever to the upper position and rotate the spoke handles to the right
to retract the tap from the hole.
Press the lever lock and set the ON/OFF lever to the horizontal (‘0’) position to stop
the motor, replace the entering tap (tap no. 1) with the bottoming tap (tap no. 3), and then tap
again, proceeding as described before.
After the work is finished and the motor stopped, set the second gear, and then run the
machine for a while without load, which will improve lubricity.
2.8. Maintaining the air preparation unit
Maintain the air preparation unit as required to keep the water trap drained, filter cleaned, and
the oil reservoir filled so that there are 12 drops of oil per minute. Use only oil whose ignition
temperature exceeds 260°C (500°F). If the machine is to be left idle for at least 24 hours after
the work is finished, increase the delivery of oil and run the motor for 2–3 seconds, which will
prevent rusting and degrading of the rotor vanes.
as often as possible to allow chips to be removed from the hole. If the grooves of the tool
are clogged, stop the motor and use a brush to clean them. After the drilling depth exceeds
40 mm (1.6’’), apply the cutting fluid manually into the drilling area.
After the hole is made, retract the tool from the workpiece, and then press the lever
lock and set the lever to the horizontal (‘0’) position to stop the motor.
To move the machine to another drilling spot, first release the magnets by rotating their
levers as far as possible to the right, and then either use a crane for transport or disassemble
the machine as described before and reassemble it in another location. Releasing the
magnets from thin or round workpieces results in the magnet lever acting as a spring. In such
a case it is extremely important to hold the lever tightly when rotating it to the right or else the
lever may hit the magnet with significant force and permanently damage the magnet.
After the work is finished and the motor stopped, set the first gear, and then run the
machine for a while without load, which will improve lubricity. Next, stop the motor, clean
chips and excess coolant from the machine and tool, close the valve of the cooling system,
and then press the pilot pin to expel the coolant remaining within the system. Finally, release
the magnets, and then unplug the machine from the supply, and remove it from the worksite.
