6-2. Drilling Procedure
(1) Punch Marking
Put a rather large punch mark in the workpiece by
driving a punch down with a hammer. The punch
mark will be used as a guide for drilling operation
that follows, so it must be made in accurate
position. (Fig.21)

(2) Keep the Magnet and Workpiece Contacting
Surfaces Clean.
WARNING
●
Always keep surfaces clean.
Always keep the Magnet surface clean. Always
keep the work piece surface clean. If there are any
foreign objects between the Magnet and the work
piece surfaces, this will reduce magnetic power.
This could cause the machine to move during
operation. This can result in an accident. Keep
all surfaces clean of rust, chips or other foreign
material.
(3) Aligning with Punch Mark.
Turn the Rod Handle counterclockwise to slightly
lower the cutter and align the tip of Pilot Pin to the
punch mark. (Fig.22)
