Dobby
Mount the left and right-hand side pieces with in each case two legs and a connecting bar. The wooden dowel
into the groove of the leg positions the connecting bar at the correct height. Use the Allen bolts and Allen key 5 mm.
Fix the two holders of the shaft with hand wheel on the right side piece (spanner No. 10).

If disassembled, slide the holders, bobbins and pedals onto the axle.
The eyes of the bolts on the pedals are on top side, the holders with the nuts are on top side.
Mount the holder with the pedals at the back between left and right side with two Allen screws.
Then place the dobby mechanism between the 2 sides and fix with 8 Allen screws 6 x 70 mm, 4 on each side.
Finally the loom can be placed on the floor stand with dobby.
Make sure that the bottom metal bars of the
shafts fits in a correspondending aluminum profile. 		Each leg of the floor stand has a hook that
fits around the connection rail of the loom.
In the front, the metal lever must be connected
with the left and right pedal by means of 2 chains.
Make sure the pedals hang a little above the floor
in lowest position. 		At the left side, the 2 chains must be connected with
the 2 small pedals and the tension spring with
the eye behind on the wide pedal.
In the lowest position of the wide pedal, it must
be possible to control the small pedals.
You can pull out the drum along the
right side of the dobby. 		With pliers you can put the
metal pegs into the holes of
the program bars. 		Take attention that you turn the
pegs in the correct direction.
Place the drum on its place, put
the belt on the pulleys and block
the drum with the slides on both
sides. 		The program bar, of which te side
with number (here 19) coincides
with the top of the front board,
is the active one. 		If desired, you can adjust the
hand wheel with numbers
(loose the black star button).
If you push the right pedal down, the 'knife' (flat metal rod) will push up the hooks that are selected.
They, in turn, will bring the shafts upward. You can change the height of the shed.
Use two fork spanners No. 13 (for nut and locknut). You can lock the bolt (of the connection between
the knife and lever) on a different place in the securing groove.
Do so at the front as well at the back in the same proportion.
At the back is a tension spring. Which helps to rise
the shafts. You can tighten or loosen the spring.
Use two fork spanners No. 13. 		In front there is a wooden lever with ball bearing,
which ensures that the drum remains in correct
position. You can adjust this position by shifting
the bearing (with 2 fork spanners No.13).
If the shafts go up, a pawl
turns between 2 notches so
that the drum can not turn. 		The side of the notch with
number (here 19) must be
on the same height as the
upper side of the frame. 		The drum is rotated by means of two wooden
pawls, the left pawl allows the drum to turn
forward, the right pawl let it run backwards.
Those pawls must be able to move freely.
The wooden pawls are mounted sit on a shelf, which
can move about. Make sure the retaining bolts are
a little loose.
The movement of the shelf is bounded by two bolts
which can be adjusted (do not change). 		The trapezium wooden piece is connected with the
small pedals by means of two chains.
A traction spring (at the wide trapper) ensures that
the shelf with pawls return to its neutral position.
You can tighten the spring if necessary.
If a blockage occurs between the drum with pins and
hooks, you can unlock the hooks.
Remove the top axis (perpendicular to the hooks).
You can use hammer and punch.
Then you can pull out the hooks upwards.

A possible cause of a blockage is loosening of one
of the bolts which fix the metal levers to the ax
(front and rear).
The knife that pushes up the hooks, should be
horizontal in rest position (lowest position).
If this is not the case, loose the screws 2 and 3.
Make sure that the screw (1) (front
and rear) is properly fastened.
The screw fits into a hole in the
axe which connects the levers. 		With the knife horizontally in lowest positionon (4), you can tight the
adjustment screws (3) with a fork spanner 13, then the screws (2) with a
fork spanner 17. Do that simultaneously at the front and at the back.
