Mounting of CER carriage, roller type carriage with manual feed
1.
There is a latch on the CER carriage which prevents it from sliding along the track.
!
Important!
When mounting the CER carriage on the track it is important to don’t let go of it until you
are sure the latch is in a position so the drill motor cannot unintentionally slide along the
track, see pictures above.
2.
Open the handles.
3.
Fold the carriage CER on to the track with the side without handles first.
4.
Fold on the other side of the CER-carriage and close the handles. First
the lower handle.
5.
Adjust the carriage CER along the track so that the feed gear fits the
rack on the track, then, close the upper handle.
6.
Put the latch so that it cannot unintentionally be moved downwards
when the drill rig is mounted for vertical drilling downwards.

Adjusting the rollers on CER carriage
To avoid play between the carriage and the track, the eccentric rollers need to be adjusted at regular
intervals.
c. Do the same procedure for the lower rollers.
!
Important!
Do not over tighten the screws, as this may damage the thread.
a. Locked position, in
either direction.
b. Neutral position, used
when drilling.
b. Use the 19 mm wrench and a torque wrench
with a 6 mm hexagon to tighten the bolt to 38
Nm.
a. Open the upper handle. Then turn the handle
inwards at the same time using a 19 mm wrench to
tighten the screw for the eccentric roller on the
other side. The rollers should be fairly hard
adjusted on the track to remove all play.
