If you have purchased the RB-aggregate as an extra equipment for your grinder, and the
grinder i produced before around 2011, initially two threaded holes must be established in
the grinders Fork for contact weel and then the role holder is mount with the new
grindingbelt. The procedure is described below.
2.1.a Dismantling
Remove the sparkbox (F) and holder of the grinding facility holder (B) from the grinder.
Figur 2.1.1 Parts of a grinder.
2.1.b Establishment of threaded holes.
Establish as accurately as possible two M6 threaded holes in the belt grinder's fork for
contact weel. Belt grinders manufactured before around 2011 do not have these holes.
See grinder split draft position 23 and place the holes as according to the drawing in figur
2.1.2.

5
Figur 2.1.2 Dimensions for establishing of thread holes.
2.1.c Mounting the Fork Bracket
The fork bracket is tightened with two screws, see below. Make sure the underside of the
little plate seen on the upper fork bracket is level with the top of the fork of the contact
wheel (see picture below). You can hold a finger on top of the support plate while fastening
the bracket.
Fig. 2.1.3 The fork bracket is mounted on the grinder.
2.1.d Mounting of roll holder.
Roll holder and justification part is mounted as seen below, left on fig. 2.1.4. Fasten the
justification part that is situated to the right by the M6-screw. Mantle then the grinding belt.
(grinding belts are given in sec. 5.1: Technical Data).
Check that the roll holder sits straight by measuring the distance between the cross bar of
the roll holder and the shaft of the contact weel in both sides. In case it is the right contact
disc that sits in the roll holder (corresponding to the thickness of the pipe to be notched)
you can just go ahead. Otherwise change contact disc. See section 3.4 for placement of
contact disc.

2.2 Installing Belt Grinder and Mounting RB-Aggregate.
In the following you will need the tools below:
Spanners 2x17mm
Spanners 1x13mm
Spanners 1x10mm
1x3mm Hex key
1x5mm Hex key
Spirit level
2.2.a Installing the belt grinder.
The belt grinder should be installed at a level, smooth, solid surface. Attach it to the floor
and tilt it to horizontal position.
2.2.b Dismantling of two bolts.
Dismantle the two screws M10x16 on the right side of the belt grinder. See fig. 2.2.2.
2.2.c Connect the bodies of belt grinder and aggregate.
On the bottom of the belt grinder body is found one or two slotted holes. This is the belt
grinders original holes for mounting the spark box. The spark box is dismantled.
On the draft below the back side of the aggregate is seen to the right and the front of the
belt grinder is seen to the left. The draft below only shows one slotted hole as with a 75
model, where as 150-models have two slotted holes. The arrow starts at the assembling
part which is specially designed to connect belt grinder and RB-aggregate. The
assembling part has two threaded rods for a 150 RB-model as it follows.
Slide the front end of the aggregate in around the beltgrinder as the arrow shows on the
figure below. Push the aggregate in so the bottom of the aggregate goes under the bottom
of the belt grinder front and so the assembling part goes into the slot.

7
Figur 2.2.1 Samlingsgevindstykket forener de to kroppe.
The assembling part should go right to the bottom of the slot in the belt grinder. Tighten
the nut underneath loosely so it is possible to make further adjustment.

8
2.2.d Mounting two bolts on the right side.
Then mount the two bolts M10x16 on the right side (see the figure below at the arrows),
they are tightened loosely with possibility of further adjustment.
Fig.: 2.2.2 Two screws M10x16 on the right
Belt grinder and aggregate are now positioned horizontally at the top by help of the Spirit
level. The belt grinder can be tilted and the aggregates foot has 4 screws under making it
possible to stabilize and adjust the height. Tighten the nut(s) on the assembling part at the
bottom of the aggregate. Tighten them well! The two bolts on the right side are also
tightened.

9
2.2.e Adding the right and left support brackets.
Fig.: 2.2.3 Suppport Brackets are mounted
The support brackets (left: S2 and right:S1) sits upside down during the shipping. When
mounted they counteract a vertical movement of the roll holder. Dismantle a screw and
turn them upwards (see figure 2.2.3) with the split inside the oval hole at the top. Tighten
left and right support bracket (S2 and S1) tightly with the two M6x12 Allen Screws.
2.2.f Dismantling and attaching of the housing.
Fig.: 2.2.4 The housing is dismantled by loosening of the two screws.
On the draft above the housing is seen in grey. The housing can swiftly be taken off and
on by loosening and tightening the Allen Screw M6x12 at the bottom of each side of the
housing. The left screw is seen on the draft.

2.2.g The belt grinder is prepared
This section concerns users who accessed the belt grinder and aggregate as a set. If you
have already a prepared belt grinder you can jump to the next section 2.2.h.
The belt grinder is in standard delivered equipped with a speed motor with motor brake,
switches (X) with overload relays, zero voltage poles, and coupled to the desired voltage.
! The electrical connection must be performed by a licensed electrician. It should be
verified that the motor (and possibly the ventilator) has the correct rotation (see the arrow
on the motor).
2.2.h Preparation before use.
Before use, eye protection, suction hoses and dust bag should be mounted. Clamps for
installing the suction hose is found in the dust bag. Eye protection (A) should be mounted
in the eye protection bracket (see Fig.: 2.2.1). Check that the aggregate does not touch the
belt.
Fig. 2.2.5 Belt grinder with attached RB aggregate 150
2.2.i Handle adjustment of the belt straight way
The following justification is swiftly done with handle D in case of receiving the belt grinder
and RB aggregate as a set. The other way of adjusting belt straight way was handled at
the production site. Therefore it is possible to start the grinder and control that it is running
straight and stable as follows:
1. Turn the contact wheel (E) by hand and adjust the belt with the handle (D) until it
runs straight.
2. Start the engine carefully and fine tune again with the handle.

11
If the handle can not get the belt to run straight it is necessary to make a different
adjustment. This may, for example, be the case if you have received the RB unit as extra
utils. of the tape straight way out in the following section 2.3.
2.3 Thorough adjustment of the sanding belt.
If the belt starts running unevenly and the handle (D) on fig. 2.2.5 cannot make the belt run
straight it is necessary to make an adjustment with the adjustment part. Via the adjustment
part seen on fig. 2.3.1 you can change the angle of the contact disc which is relevant for
the sanding belt run.
Fig 2.3.1 The adjustment part can adjust the grinding belt.
2.3.a Get ready to adjust
Loosen the right and left support brackets and turn the handle D so it is approx. midway
between the two extreme positions. Check that the machine stands stable and that both
bodies are horizontal. The nuts B1 and B2 are shown in Fig. 2.3.1 should be free and
detached as the drawing.
2.3.b Adjustment with adjustment part
Turn unbracobolt w/spring in adjustment part labeled "A" fig. 2.3.1. This will move the
thread in adjustment part up or down and this will result in the tape runs either right or left.
If you turn the bolt counter clockwise it influences the band to the left and turn the bolt
clockwise influences the band to the right. Run the belt forward by hand to see the result of
your adjustment. When the tape runs just it is adjusted. Then the machine can be started
you can fine tune with the same bolt while it is running.
2.3.c Adjustment of grinding belt.
Check that the belt runs level on the roll. First through manual operation. If the belt runs to
one side, it can be adjusted using an unbraco-bolt w/spring (pos. 34 and 43). Then the
machine can be started at low speed and can be fine tuned with the same bolt. The
adjustment is locked by tightening the two nuts (pos. 32) on the adjustment part. The
rough adjustment should only be done occasionally. To ensure that the adjustment does
not shift, the supporting brackets are now fastened (Nos. 12 and 13 (RB)).
For normal operation, the belt is fine-tuned by using adjustment lever D as usual on the
belt grinder. (see drawing below)

3.3 Maintenance
Clean the suction ducts regularly. The dust bag is emptied after use. Replace the grinding
surface on the level grinding table as needed.
For belt replacements, the pressure is taken off the belt by turning the handle (D) on fig.
2.2.5 counterclockwise. The housing (see fig. 2.2.4) is disassembled and the worn belt is
removed. Put a new belt on and verify that the direction of the arrows on the back of the
belt, are equivalent to the direction of the rotation. The handle (D) is turned back clockwise
until the belt is tightened. And then the housing is assembled again.
Check that the belt runs in the middle by turning the belt around with your hand and adjust
inwards if necessary.
3.4 Roll holder –location of contact discs
The distance between belt grinder and contact weel must be changed when you wish to
grind another pipe dimension.

3.5 Adjustment of the pipe holder’s height compared to the roller
It is important that the contact disc and the pipe holder are parallel and at the correct
height.
3.5.a Contact disc and Pipe Holder is made Parallel
The distance between the pipe holder table surface and the top of the roll in the right and
left side should be the same (=parallel).
Fig.:3.5.1 Height difference between Contact disc and pipe holder table is measured.
If there is a measurable height difference this should be adjusted. On fig. 3.5.2 the pipe
holder is seen. The lower part lies in reality inside the body and under the body you will
find the shown bolts and nuts protuding out.
Figur 3.5.2 The Pipe Holder is seen from below- the body is invisible.
First you loosen the nuts that the arrows point to. The table lies now loose in the body of
the aggregate on top of the 4 bolts w/nuts(V1, V2, H1, H2) that is seen on fig. 3.5.2. You
must now rotate in pairs on either the two nuts on the left side or the two nuts on the right
side.
By turning the nuts V1 and V2 one circuit downwards and after that the bolt one circuit up
the table will move one mm  upwards in the left side and similarly for H1 and H2. So

17
when you finish making the pipe holder parallel to the contact disc you fasten the two nuts
that the arrow points to again.
Height adjustment of pipe holder to the middle of the roll holder is done through a similar
adjustment of the 4 screws mentioned above. Now you have to turn all 4 nuts at once. One
full turn equals a 1 mm  adjustment.
3.6 Angle of Pipe Notching
The grip (pos. 41 on the spare part list of the aggregate) is loosened and rotated to the
desired degree, after which it is tightened, and the subject is placed in the vice and
fastened.
Fig. 3.6 shows a pipe and sanding belt from above. A RB pipe grinder can grind at a
maximum angle. The width of the band, however, limit the scope. An RB75 is limited
