Horizontal Alignment
For safe and accurate work, it is important that
all instrument feet are in uniform contact with the
installation surface.
The stainer is horizontally aligned at the factory.
If a completely level or horizontal surface is not
available at the installation site, the instrument
must be realigned.
For this purpose, the instrument feet (
25
) are
height-adjustable.
•
For alignment, loosen the locknuts (
26
) using
a size 11 open-end wrench.
•
Adjust the instrument feet (
25
) until the instru-
ment is in a stable position at the installation
location according to requirements.
•
Retighten the locknuts.
4.3 Setup
Mounting the Support Bracket
To ensure that the instrument cannot tip over
when its keys are pressed, the support bracket
(
27
) must be mounted on the rear.
•
To do this, first unscrew the two Phillips head
screws (
28
) with a screwdriver. Place them
together with the two associated washers (
29
)
•
Place the support bracket against the rear of
the instrument (
Fig. 20
), reinsert but do not fully
tighten the two screws.
•
Press the support bracket down onto the sup-
port surface until a face of the plate lies flush
with the bench surface. Tighten the plate in
this position.
