Using the damper stopper
Engaging the damper stopper, located on the performer side in the center of the long frame,
holds the damper open (letting the tone bars sustain) without having to continuously press the
damper pedal.
While holding the pedal down with your foot, press the stopper knob and remove your foot from
the pedal. The pedal remains in the lowered positioned and locked.
Press on the pedal again to automatically disengage the stopper and restore normal operation.
* If pedal height adjustment in step 3-1 "Pedal height adjustment" is set too low, the damper stopper
may not function properly. Please set the space between the bottom of the pedal and the floor to more
than 2cm.

Adjusting the tone bar height
CAUTION
Holding down both low and high register side side frames, loosen the slide guide fixing bolts.
After adjusting the instrument to a comfortable height, tighten the slide guide fixing bolts to secure.
Use the guide lines on the slide legs as a reference and adjust the height so that the instrument's
playing surface is parallel to the floor.
A gas spring system is incorporated into one of the legs on the high register end, and another leg
on the low register end. When the slide guide fixing bolts are loosened on the low register side,
the side attached to the leg without the gas spring may slightly lower (diagram A) however, this is
not a sign of any problem. When adjusting instrument height, slightly lift up on the side that is not
equipped with the gas spring.
After assembly is complete, make sure all nuts and bolts are tightened firmly.
Equipped with gas springs
The brown felt attached to both sides of the glockenspiel's main unit and the cardboard attached at two positions
on the low register side are part of the packing materials used to hold the tone bars in place. After assembly is com-
plete, pull on the felt and cardboard to remove.
When loosening the slide guide fixing bolts be sure to hold down the side frame
from above. The side frame can suddenly rise which is extremely dangerous.
Without gas springs
The stopper slides in between the adjustment nut
and the main unit to hold the damper open.
