Adjusting The Head Tension; Head Replacement; Replacing The Head - Roland KD-140 Owner's Manual

Adjusting the Head Tension

Please tune the head before playing the KD-140.
A slightly looser tuning will make the beater response and
rebound similar to that of an acoustic bass drum.
To avoid malfunctions, please observe the following
points.
• Adjust the head so that it does not sag.
• Adjust the tuning bolts so that they do not wobble.

1.
Adjust each tuning bolt little by little, working back
and forth across the head in the order shown in the
illustration.
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.
2.
Adjust each tuning bolt so that the head is
tensioned evenly.
• On the KD-140, adjusting the head tension affects
only the strike response of the head; it does not
adjust the pitch of the sound as it would on an
acoustic drum. To adjust the pitch, edit the sound
parameters of your drum sound module. For details,
refer to the owner's manual of your sound module.
• The tension of the head will change during extended
use. Readjust the tension as necessary.

Head Replacement

When to Replace the Head
A drum head does not last forever, may eventually wear out
and might need to be replaced if any of the following occurs.
• The head surface is torn
• The head is very worn out at the beater strike point
• Slack portions remain even when head tension is correct
To replace a head, contact your dealer or Roland service
center.

Replacing the Head

• 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 head, 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.
