7.2 Adjusting the angle of the drill stand with AB52
CAUTION
 Before tilting the column, ensure that the drill stand is firmly fastened by an anchor bolt to
the material to be drilled, and the drill motor with the carriage block is removed from the
column.
 Take care not to pinch fingers between the column and the base.
 Wear protective gloves.
NOTE
The angle scale indicates approximate angle degrees. If higher precision is required, alternative
measuring method should be used.
Follow the procedure below.
1) Loosen and remove hex. bolt (M12x70) which fixes the column to the base on the front side of the
base. Also, remove the spring washers (2-12). Keep them for the future use.
2) Loosen 2 pieces of hex. bolts (M12x90) on the side of the column so that the column tilts.
3) Tilt the column to a desired angle.
4) Tighten 2 pieces of the hex. bolts (M12x90) on the side of the column. The tightening torque is 60
Nm (44 lbf・ft) each.
5) When using it as a fixed drill stand, ensure to re-attach hex. bolt (M12x70) and spring washers
(2-12) and tighten the bolt. The tightening torque is 60 Nm (44 lbf・ft).
