To improve lubrication, after
the work is finished and the motor is stopped
toggle
the gear
to the
opposite position
(for
example:
from gear II to I) and run the drilling
machine
for
a
while
without
load.
Then,
stop
the motor and disable the electromagnetic
base,
unplug
the
power
cord
from
the power outlet, and clean metal chips and coolant
remainder from the machine. Tighten the bottle cap of the cooling system, close the
valve, and press the pilot pin to expel the coolant remaining within the system. Before
putting the drilling machine into
the
tool
box,
disassemble the cooling system and
remove the tool from the holder using gloves.
3.8. Tapping
Position the machine in such a way to place the tap no. 1 above the hole with proper
diameter. With the hole diameter being too low, tapping may be impossible because
of excessive milling resistance and insufficient motor power.
Select the first gear using the gear lever and set the rotation direction switch to
position ‘R’. Spread grease on the working part of the tap to prevent seizure and
extend durability. Then, start the motor with the green MOTOR button and slowly
rotate the spoke handles to lower the tap to the workpiece and begin tapping. Once
tapping with the tap no. 1 is finished, stop the motor using the red MOTOR button
and
set the rotation direction switch to position ‘L’. Then, press and hold the green
MOTOR button to retract the tap from the hole, and release the button once the tap is
retracted.
At this stage, replace the tap no. 1 with the tap no. 3 and perform the tapping
again, proceeding as described before. To improve lubrication, after the work is
finished and the motor is stopped, switch to gear II and run the drilling machine for
a while without load. Then, stop the motor and disable the electromagnetic base, and
unplug the power cord from the power outlet.
