Yamaha HS840 Owner's Manual

r Spring Tension Knob

The Spring Tension Knob supplies tension control over a 11-step range, To increase
tension, slide the Spring Tension Knob up (Fig. A) to any position you like (use the
scale as a reference) and then rotate the knob to the left to lock in place. (Fig. B)
To reduce tension, rotate the Spring Tension Knob to the right (Fig. C) and slide to
any position you like.
To increase tension, slide the Spring Tension Knob up, to decrease tension, slide the
Spring Tension Knob down.

t Footboard Stabilizer Rod

The Footboard stabilizer rod should attach to holes in the frame at the bottom
of the hi-hat base.

y Spur

The large heavy-duty rubber feet prevent unwanted movement of the hi-hat
stand during playing conditions.
To minimize slippage further, there are two spurs in the frame.
These spurs can be extended as needed by adjusting the turn screws pro­vided on either side of the frame base.

u Leg Position Adjustment

Loosen Bolts A and B shown in the illustration to
the right to change the position of the legs
(footboard). After the position has been
determined, tighten both Bolts A and B firmly.
Also, we recommend that the legs be positioned
in the same manner as shown in the illustration
on the left so as to leave some space available
for setup and to provide sufficient stability for the
stand. (This setup is for right-handed drummers.
For left-handed drummers, please set up in an
opposite manner.)

Note:

To maintain smooth action, occasionally apply some grease-grade oil to all
of the moving parts.
Be careful not to use excessive force when tightening the extender base nut
as this may damage the nylon bushing inside the tube.

q Cymbal Support Plate

To install the bottom hi-hat cymbal, remove the hi-hat clutch assembly and
place the cymbal on the felt washer on the cymbal support plate. The angle of
the bottom cymbal can be adjusted by turning the angle bolt on the underside
of the support plate.
To adjust the angle of the hi-hat cymbal, use the Knob Bolt located on the
underside of the cymbal support.

w Hi-Hat Clutch

To install the top hi-hat cymbal, loosen the wing bolt and remove the entire hi­hat clutch assembly from the upper pull rod. Next, remove the clutch nut and
position the cymbal between the two clutch felts.
After installation, tighten the clutch nut on to the clutch assembly to secure the
cymbal. Place the entire assembly onto the hi hat upper pull rod and tighten
the wing bolt to secure the desired position of the top cymbal.
The lock nuts on the top of the clutch can adjust the feel and sound of the hi
hat cymbals. To obtain a loose sound, open the nuts off of the felt; for a tight
sound, close the nuts onto the felt. Once the desired sound has been ob­tained, tighten firmly the lock nuts onto each other.

e Position Clamp

Once the bottom hi-hat cymbal height has been decided, the position clamp
can be used to mark the settings for future set ups and to prevent uninten­tional changes during musical performances. Use a drum key to firmly tighten
the position clamp into place.

* Specifications and design are subject to change without notice.
