If you are going to drill holes deeper than 50
mm (2″), retract the tool above the
workpiece as often as possible. This allows chips to be removed from the hole. If the
grooves of the tool are clogged, turn off the motor and use a brush to clean them.
After you get to the depth of 40
mm (1.6″), retract the tool above the work-
piece as often as possible. Then, manually apply the coolant from the bottle into
the drilling area.
After the hole is made, retract the tool from the workpiece, and press the red
MOTOR button to turn off the motor. Before you move the machine, set the MAGNET
switch to ‘O’ to turn off the base.
After the work is finished and the motor turned off, set the gear switch to the op-
posite position. Then, turn on the motor and let it operate for a while with no load to
improve lubrication. Next, turn off the motor and the base, and then unplug the
power cord. Clean the machine and the tool, and then remove the machine from the
work area.
Tighten the bottle cap, close the valve, and then press the pilot pin to remove the
coolant that remains in the cooling system. Before you put the machine into the box,
remove the bottle, and use gloves to remove the tool from the holder.
