Spindle speed selection:
Is effected by the three knobs on the left side of the spindle housing according to the
plate situated under the knobs. Gear shifting may not take place while the machine is
running.
Elevating drive:
The machine is equipped with an elevating drive for the vertical movement of the
drill head. First loosen the two handles on the right hand side of the spindle housing,
clamping it to the column. The movement is actuated by means of a switch situated in
the front of the drill head. A built in friction clutch in the gear box of the elevating
device prevents damages in case the drill head moves against stop in either direction
or if it gets locked.
Power feed:
The selection of the four different feed rates is effected by means of the dial on the
front of the spindle housing.
NOTE!
The dial cannot be turned directly from the highest to the lowest feed or
vice versa, it is necessary to go step by step.
Selecting of feed rates can be made at lower speeds when the drill is running but not
under load. The desired drilling depth is set by the depth stop and scales on the front
side of the spindle housing. The engagement of the power feed is effected by moving
the dial to the right and then down as per instructions on the sign. By reaching the
preset drill depth the spindle returns automatically to its upper position and stops to
rotate.
NOTE!
Always see to it that the fine feed is disengaged before engaging the power
feed.
Fine feed:
The fine feed is connected and disconnected by the lever situated under the fine feed
wheel. In vertical position of the lever the fine feed is disconnected, and when in
horizontal position it is connected. After the operation has been finished always
disconnect the fine feed.
Locking the quill:
The drill is locked with the screw on the lower front of the quill housing.
