Replacing the Covering
• Do not apply excessive force to the sensor and
cushion located under the head. Doing so can
interfere with accurate detection, and may damage it.
• When replacing the covering, avoid touching any
parts other than the wing bolts, and be careful that
no foreign matter enters the interior of the unit.
Otherwise, you risk causing malfunction.
• Be careful not to hurt your fingers on the corners or
points of the metal parts.

Pull the other end of the covering so that there is
no slack, and then tighten the other wing bolt to
securely fasten that end.

and plate.
6.
Attach the hoop and head, and tighten the tuning
bolts.
7.
Adjust the tension of the head. Refer to "Adjusting
the Head Tension" (p. 8).
Fully tightening a tuning bolt at only a single location
will produce uneven tensioning, which will make it
impossible to achieve correct strike response and may
also cause malfunctions.
