High carbon steel:
600 RPM
Stainless steel:
300 RPM
Generally speaking, the smaller in relation the drill bit, the
greater the RPM required.
Wood requires higher speeds than metal.
Metal is usually drilled at slower speeds; cutting oil is applied
if necessary.
Warning:
Always keep your hands well clear of the rotating bit.
Do not remove chips and workpiece parts until the machine is
at a standstill.
Always close the chuck guard and pulley cover before you
start the machine.
When using a drill press vice, always fasten it to the table.
Never do any works "freehand" (hand-holding the work piece
rather than supporting it on the table), except when polishing.
Support long workpieces with helping roller stands.
Do not use wire wheels, router bits, shaper cutters, circle
cutters, or rotary planers on this drill press.
Never cut magnesium - high danger to fire!
7. Setup and adjustments
General note:
Setup and adjustment work may only be carried out after
the machine is protected against accidental starting by
pulling the mains plug.
7.1 Removing the Chuck and Arbour
Unplug the machine from the power source.
Lower the quill using the down feed handle.
Rotate the spindle to align the key in the spindle with the key
hole in the quill.
Insert the drift key (V, Fig 3) into the aligned slots and tap
lightly. Have another person (or a protected table) catch the
chuck and arbour assembly as it falls away from the spindle.

7.2 Adjusting the Depth Stop
To drill multiple holes at the same preset depth, use the
depth stop (J, Fig 4).
With the drill bit in the chuck, lower the down feed handle to
advance the drill bit to the work piece.
Lock the depth stop to the desired cutting depth.
J
The drill bit will now advance only to this point.
7.3 Changing Spindle Speeds
Unplug the machine from the power source.
Loosen the locking screw (W, Fig 5) on the pulley cover, then
open the cover.
Release the belt with the tension lever (C).
Change the belt location according the speed chart and the
speed you desire (Fig 6).
