ROC-ANGIE

ROC-ANGIE measures forward and backward angles and right and left angles from the vertical position of the feed. If straight vertical holes are drilled, it is unnecessary to aim ROC-ANGIE. The machine can stand in any direction at all relative to the bench if ROC-ANGIE is correctly aimed.

ROC-ANGIE can be turned round a vertical axis and aligned in the desired direction instead of aiming the machine in a special direction at each hole. Use a compass or make an own aiming point if there is not an aiming point (for example, tree, telegraph pole). The steel in the machine can affect the compass needle if using a compass. The angles that are shown in the receiver are always relative to the aiming point, not to the machine, if ROC-ANGIE is aimed.

Preparing for Assembly ROC-ANGIE

1. •
   1.
   Set the feed in a vertical position with the spirit level.
2. •
   2.
   Adjust forward and backward for a accurate vertical reading.
3. •
   3.
   Adjust left and right for a accurate vertical reading.
4. •
   4.
   Check that both left and right angles and forward and rearward angles are still vertical.

Assemble ROC-ANGIE

Adjust ROC-ANGIE to Zero Reading

NOTE

A final check must be done by rotating ROC-ANGIE around its own axis while observing the two scales - they must show 0º in all directions

Precondition

• The feed must be in vertical position, both left and right angles and forward and backward angles.

1. •
   1.
   Loosen and retighten all bolts by hand.
2. •
   2.
   Check the upper scale and adjust the left and right bolts (A) to an exact zero reading on the upper scale (C).
3. •
   3.
   Tighten the left and right bolts by hand.
4. •
   4.
   Check the lower scale (D) and adjust ROC-ANGIE forward and backward to an exact zero reading.
5. •
   5.
   Tighten the front and rear bolts (B) by hand. Check left and right, forward and backward once again and adjust as necessary.
6. •
   6.
   Tighten all bolts using a torque wrench.

Install ROC-ANGIE

1. •
   1.
   Choose an aiming point preferably far away.
2. •
   2.
   Loosen the handle on the top of ROC-ANGIE.
3. •
   3.
   Look through the aim. Turn ROC-ANGIE around until the center arrow in the aim is exactly in the middle of the aiming point and between the two outer arrows.
4. •
   4.
   Adjust the aim or move it to the other side by undoing the knob at the bottom of ROC-ANGIE if necessary.
5. •
   5.
   Lock the handle.
6. •
   6.
   Adjust the feed to the correct angle.
7. •
   7.
   Start drilling.

Aiming Examples

Two different ways of aiming ROC-ANGIE are described here. In the first example, the aiming point is in line with the blasting direction.

A	Bench
B	Reference point

In the second example, the aiming point is parallel with the bench. Deciding which method to use depends on the nature of the terrain and the distance to the aiming point.
