4.4.2
Rear support for 70 mm column
For most drill operations a back support is needed to give greater stability, for example when drilling with
high pressure and high load. The back support should always be used to stabilize the column, especially
where circumstances are hard and demanding.
4.4.3
Mounting of carriage CE1 on 70 mm column
CE1-70 carriage with friction brake
1. Loosen the socket on the hydraulic feed unit or the 19 mm Hex bolt on the friction brake.
2. Put the carriage on the column.
3. Adjust the height of the carriage by turning the feed shaft with a knuckle bar.
4. Tighten the socket on the feed unit or the hex bolt on the friction brake until the carriage doesn’t
slide down the column.
5. For optimum preload of the rollers on the column, the rear rollers should be adjusted using a ½”
spanner and a 15 mm wrench. Adjusted correctly, this eliminates all play between the carriage and
the column. Do not set the rollers too hard. The result will be premature wear of the column.
6. Lock the eccentric shafts for correct pre load of the rollers, by tightening the screw with a 15 mm
wrench.
The drill unit (gearbox, spindle unit and hydraulic motor) can mounted on the carriage with the drill spindle
pointing in both directions along the column. Note that the drill unit can be mounted in two positions along
the carriage.

Important!
•
Be careful when mounting the carriage on the column. Make sure the
socket / hex bolt is tightened to avoid clamp injuries. Do not overtighten!
