Speed selection
Setting the Spindle Speed
The rotation speed is set using the gear lever on the left side of the spindle case. Set it according
to the sign on the front side. The machine must be at a stand still to make the switch. If any of
the gears are difficult to get into position, rotate the spindle nose manually. By setting the
machine to “On” position and turning the speed knob at the front, it can be set to the ultimate
speed by checking the speed display at the top of the machine front (picture 4).
Machines equipped with Automatic Feed
The feed speed is set using the knob on the right side of the feeding box. The feeding rate can be
set while the machine is in operation, but not when loaded.
The knob cannot be turned directly from the highest to the lowest feed rate, or vice versa. You
always have to go through the middle positions.
Feeding occurs automatically when drill pressure occurs and the feed handle is pressed
furthermore to a click stop. When the desired drill depth is achieved, the spindle returns to its
upper position.
Handling
The machine is equipped with a 1-speed motor.
Select the spindle speed using the gear lever on the left side of the machine. See the sign on the
front side of the machine.
If any of the gears are difficult to get into position, rotate the spindle nose manually.
Set the Machine in on position by the push button marked 1 at the front and 0 to turn off
(picture 4).
NOTE! The machine cannot be shifted during operations.
Hand-fed Drilling
The claw coupling (1), picture 2, on the hand lever must be pushed in.
Set the drill depth using the scale and the lockable lever on the front of the machine. Also, the
digital depth scale shows a more accurate depth and adjustment possibilities
Machine-feed Drilling
Machine feeding provides a complete work cycle with only one handle. The work cycle is
obtained by feeding the drill spindle down against the work piece. When drill pressure appears,
the machine feed is connected and the machine drills to the set drilling depth. The drilling
spindle then returns to the withdrawal position. The machine feed's repeated accuracy is 0.1 – 0.2
mm. If required, feeding can be cancelled by holding back any of the hand feed levers.
Setting the machine-fed drill depth:
• Lock the drill depth scale in its upper position.
• Remove the coupling (1) towards the right.
• Loosen the two female screws (2) in the hand lever fastener.
• Feed the spindle down to the desired drilling depth. In the event of machine feeding, the
spindle goes approximately 3 mm longer than what is set.
