How to hang up the clock case
For optimal readability we suggest to place the drilling for the wall plug approximately in
190 cm height.
Caution!
Please be careful, the door can be opened only up to 120°! By non-consideration, the
case could be damaged!
Then affix the case to the wall using the lens head screw and dowel (8 mm) provided. Under
no circumstances should you use a hook. The door of the Opus Metallica 100 case is fastened
by magnets, so it has to be fixed with a second screw at the wall. Put the case in an exact
vertical position and mark the second fixing point (at the wall) through the longslot, above the
bottom of the case. Now the clock has to be removed from the wall again.
Take the case from the upper screw and place the second, smaller dowel (6mm) at the marked
position in the wall. Fix the case again at the upper screw and set it into the exact vertical
position. and than screw in the four case screws located in the corners of the clock case until
the tips get stuck slightly in the wall.
Screw in the lower fastening screw and put the pendulum scale at the case.
How to hang in the pendulum
Caution!
Do always hold or carry the pendulum
at the free pendulum rod, never at
the adjusting-table or the plate of the
barometer-instrument.
To avoid damage of the delicate suspen-
sion spring we recommend to insert it into
the slot of the pendulum rod first, hold it
in place and then hang the pendulum to-
gether with the suspension spring into the
suspension spring block.
How to fit the movement
Remove the safety rubber band from the pallet.
When fitting the movement, pay attention to the
driving pin of the pendulum being located at the
left side of the beat adjuster. (s. fig. yellow point)
Hang the end of the steel cord in the cable pillar
to the right at the case back.
Place the clockwork carefully onto the two pillars
and screw it on the tight by means of the two
movement holding screws.
How to set the clock in motion
Make sure the cable runs in the front groove of
the barrel wheel and the pulley.
Then hang the weight in the bow of the rope
pulley without bending the steel cable.
Wind the clock with the crank one turn counter clockwise. Deflect the pendulum until a “tick”,
caused by the drop of the escapement wheel tooth on the pallet, is audible. Watch the
pendulum scale and note the angular minutes, indicated by the tip of the pendulum, exactly in
the moment where the “tick” occurs. Now deflect the pendulum to the other side and again
note the angular minutes when the “tick” is audible. It is ideal, when the angular minutes are
equal on both sides.
If the pendulum has to be deflected more to the right side than to the left to hear the “tick”,
you can correct this by turning the adjustment screw (see above) on the pendulum rod behind
the movement to the left side.
Stop winding the clock, when the top end of the pulley is about 1 cm below the dial
ring.
