Frequently Asked Questions for tonewheel consoles and
spinets. (selected models only)
1. Q: My Hammond has two switches to
turn it on, what is the correct procedure?
At the right hand side of the music rack you will find two switches
- the first a ‘toggle’ switch which is the START
switch, and another ‘toggle’ switch which is the RUN
switch. First make sure that the RUN switch is in the ‘off’
position and then push the START switch and hold it while
you count to 8 slowly. Still holding the START switch, push
switch into the ‘RUN’ position. Hold both switches while
you count to 4 slowly, the release the START switch, leaving
switch in the ‘RUN’ position. In about 30 seconds the
organ will be ready to play. To shut off the organ, simply pull the RUN
switch to its ‘off’ position. A small light is behind the
switches, letting you know at a glance whether the organ is on or
off. In the event of a power failure or if the organ becomes
disconnected, the above procedure must be repeated in order to start
2. Q: I need to move my Hammond,
what special precautions should I take? (generator and reverb locking does not apply to all
A: If the organ is
moved always be sure that its weight is supported by the case and not by
the pedals or pedal mechanism. Be careful also not to put undue strain on the
legs. Aside from this no special precautions ore required if the organ is
to be moved only from one room to another. If it is to be moved some distance,
it is important that the generator be fastened down to the shelf. Remove and
reassemble the four sleeve and washer assemblies with sleeves the down and
tighten securely. This will prevent serious damage.
When the organ is set up for operation, the generator
should be freely suspended. To do this remove four hexagon head screws under the
shelf, turn four sleeve and washer assemblies over so that washers are down, and
replace screws, tightening them securely. Use shims under console, if necessary,
to set level in order that generator is free to move in any direction. Failure
to do this will cause noisy operation.
Later models are equipped with a reverb lock, to avoid
damage to the reverberation unit this should be carefully engaged so that the
springs are held captive by the locking mechanism. It may be necessary to remove
the back cover from the organ to do this
3. Q: Why does my organ make a
humming sound when it is turned on?
When playing the console, see that no piece of
electrical equipment having a strong magnetic field is close to it. For example,
an electric clock standing on the console can in some cases produce a loud hum
in the speaker. This may occur also if a clock or other piece of electrical
equipment is in on adjoining room close to the wall opposite to the organ.
Q: How do I oil the generators?
The generator is lubricated by a centralized system
fed from three oil cups visible inside the back. Follow the oiling instruction
on the generator cover, using the chart as a reminder. When your supply of
oil is exhausted, you may purchase another can from your dealer or direct from
With the exception of regular oiling, the organ will
require little attention. If any servicing is required, call your Hammond Organ
dealer or write to the factory. Always mention the model and serial number,
shown on the name plate.
