4.6 Set 0° angle (only BST 650 S and BST 460 S)
Unfasten the handle 8 (Fig. 2) by turning it. Press the
button 11 and keep it pressed. Swivel the column
slowly toward the 0° angle (angle scale) until the
push rod snaps into place. Turn the button to the left
and then release it. Tighten the handle.
The 0° angle is then locked into place. In order to
release the lock, press the button downward and turn
it toward the right until the push rode snaps out of
place.
4.7 Mounting the copy insert (special accessory)
A copy insert (special accessory)
can be used for hole patterns and
rows of holes.
Templates with Ø 25 mm of wood
or metal can be used for drilling the
holes of repreated drilling patterns.
Set the copy insert from below into the base plate and
tighten it with both countersink screws 12 (Fig. 3).
4.8 Working with the parallel guide (special
accessory)
The parallel guide (special accessory) can be
attached on all four sides to the base plate and be
tightened with the wing nuts included in delivery.
The base plate has read-off edges on three sides;
you can use them to read the scale on the parallel
guide.
Furthermore the parallel guide can be used as a twin
pad simply by turning it over.
The parallel guide also has a lateral stop that can be
inserted into the side-face from both sides and then
tightened with the Allen wrench included in delivery.
The scale can be read on the edges at the end of the
side-face.
5 Operation
5.1 Initial operation
Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular
attention
to
the
chapter
"Safety
instructions".
Ensure that the tool is properly fastened.
5.2 Operating method
Switch on the drill.
Use moderate pressure to press the running drill
downward until the crest of the drill thread engages
the wood. The drill then automatically continues the
feed. Once a hole has been drilled, the built-in
Zugseilden Schlitten wieder zurück. It might be
necessary to help by pulling on the handle of the drill.
The return force of the hoisting rope is continuously
adjustable (see section 4.5).
5.3 Drill holes at right angles
First set the column to the °0 angle (only BST 650 S
and BST 460 S)
(see section 4.6)
Align the drilling station to the break of the desired
bore hole. The break indicator on the base plate or
insert panel are helpful for this.
5.4 Slanted drill holes (only BST 650 S and BST
460 S)
The column can be swivelled to the
left and right by 45 degrees°.
The pivot axis is on the workpiece surface so that the
break indicator of the base plate can be used even
when swivelled.
Unfasten the handle 8 (Fig. 2) by turning it. Swivel the
column to the desired position accordinf to the angle
scale 7. Re-tighten the handle.
5.5 Stud holes
Unfasten the tension lever 4 (Fig. 1). Set the depth
stop 5 according to the depth scale 6 and re-tighten
the tension lever. (Take the drill bit distance above
the wood into account).
The surfaces of the depth stop marked in red and the
die coloured depth scale are helpful for this.
6 Service and maintenance
Danger
Always remove the drill from the
drilling station before working on
the unit.
